Happy New Year - And Welcome to National Diet Month!

If you visit your local supermarket on Wednesday morning the first thing you'll notice is that the isle that last week was full of holiday candy is now filled with expensive branded "diet" foods.

It's diet season. For the next four weeks people will eat diet bars, diet shakes, diet drinks, diet pills, and they'll drive up the price of boneless chicken breast. They'll clog the gyms and make it miserable for those of you who go to the gym every month.

It all ends the last week of January when the supermarkets move the diet food off the feature shelves and replace it with chips, dips, and Cheez Whiz for the Super Bowl. At that point most people's diets will have completely failed and they'll give up for another year.

If you've decided it's time to burn off those holiday pounds, good for you! But if you'd like to succeed on this year's diet, here are a few tips gleaned from my years of dieting adventures which you can read about in more detail on my Low Carb Diet Facts web site:

1.Avoid packaged "diet" foods and drugs. Many of them are full of soy, which is far from healthy. You can find out the facts about soy from this excellent book: The Whole Soy Story by Kayla T. Daniel. They are also filled with tons of additives of the sort you'd never eat in anything home cooked: glycerine, maltitol, modified food starch, etc. Many of these will raise your blood sugar--especially maltitol and glycerine. Raised blood sugar and/or insulin levels cause hunger.

Not only that, but bars and shakes filled with chemicals do not replace the high quality protein you find in good meat and cheese nor do the chemicals in them replace the nutrients you'll find in fresh salad greens and vegetables. A month of living on diet bars and shakes will leave you depleted of many nutrients and that, too, can make you hungry.

If you want to lose weight eat small portions of real food. Meat, soup, salad, green vegetables, cheese, colorful berries. If you keep your blood sugar flat, you will avoid hunger, which is the main benefit of a low carb diet for those of us with diabetes. If you aren't hungry, it's a lot easier to cut down on what you eat.

2. Be realistic about how much you will lose each week.

At the start of any diet you may see a dramatic drop in your weight. This is due entirely to flushing water out of your body and reducing your stomach contents. After that initial drop, you will very slowly start to lose real weight.

How much? You can see some very revealing graphs showing how much weight dozens of devoted low carb dieters lost over a period of many months HERE.

As you can see after the first couple weeks when people lose a lot of water weight, the median weight loss for a woman who weighs between 150-250 lbs is 4-5 lbs a month. That's about one pound a week. So if you have 50 pounds to lose, and "only" lose 1 pound a week you're doing great.

If you're an older lady, like me, don't even dream of losing a pound a week. A pound a month may be more like it, thanks to the natural slowing of metabolism that occurs for everyone as we get older.

3. Exercise has benefits, but weight loss is NOT one of them.

The people who sell gym memberships will promise you that going to the gym alone will cause you to lose weight. This is not true. The "calorie burning" counts you see displayed on the machines in the gym are completely fictional. This was recently documented by Gina Kolata writing in the New York Times HERE.

Many of us find that exercise makes us hungry. This is particularly true for people with diabetes because exercise makes our blood sugar fluctuate. If you come home from the gym ravenous and eat a couple hundred calories under the impression you've burned off more, you'll gain weight, not lose it. Exercise to look hot, build strength, and maintain cardiovascular fitness.

To get slim, cut out food. If you aren't sure what you are eating, invest in a food scale, weigh portions and look up the calories in that exact portion. If you don't know how much to eat, calculate your metabolic need with this handy tool: Calories Per Day Calculator. Be sure to describe yourself as "sendentary" as you probably are unless you are training for a marathon, play Football, or hang wallpaper for a living. Most of us way overestimate our activity level, even if we go to the gym.

A study of successful dieters who kept large amounts of weight off for many years found many of them only started exercising after losing the weight. That was my own experience and a whole year of near daily gym attendance did not help me lose further weight. I maintained my weight loss without exercise for several years thanks to some orthopedic problems, too.

So don't fall for the hype about exercise. Weight is about how much food you eat.

4. Cutting Carbs Helps but Calories Rule

The people who earn millions selling diet books and doing infomercials always tell you that their diet is all you need for success. Most of them greatly oversimplify the issues involved in dieting. I've met people who have lost large amounts of weight on just about any diet you can think of. I've also met people who have stalled on every possible diet, too.

So I am not going to tell you that if you cut the carbs weight will drop off like magic and you can eat luxuriously while watching pounds fade away. I find it easier to lose weight when I cut carbs--but only if I also cut my calories down significantly. Avoiding carbs controls my hunger and makes it possible for me to cut down on what I eat without feeling deprived. But for me it is the calorie levels alone that make the difference in my weight. The main reason I cut carbs is to bring down my blood sugar to healthy levels.

5. Some Diabetes Meds Make Weight Loss Very Tough

Avandia and Actos will pack baby fat cells on you and make it impossible to lose weight. Insulin can cause weight gain, especially, it seems, Lantus, though Levemir is supposed to cause little or no weight gain. I gained no weight on R insulin but did gain, rather dramatically, on Lantus. One reason to cut carbs if you are on insulin is to cut down the amount of insulin you need, this may also help you with weight loss. Insulin is a fat building hormone.

Some diabetes drugs may help with weight loss--if you cut back on what you eat while taking them. Metformin and Byetta are the only drugs with proven weight loss effects, but those effects are very modest. Studies show most people who take these drugs over a year lose only a couple pounds. You can harness their power to lose more if you cut back on what you eat.

6. Diet Pills are Dangerous and Usually Ineffective

Alli will keep you from metabolizing fat which is NOT healthy for your body as it leaches out fat soluable viatmins. But even if you can tolerate it, at the end of a year the studies show you probably won't lose more than a couple pounds and you won't keep those pounds off if you stop the drug. Is this worth the risk of pooping in your pants? That's the best known side effect of drugs that block fat digestion.

The over the counter "fat burners" are either complete scams or contain ephedra and other stimulants that are not good for your long-term health and may be very dangerous if you, like most people with diabetes, have a tendency towards high blood pressure. In that case, they can cause strokes. So if you must experiment with one of these, check your blood pressure regularly. Mostly though, they are likely to lighten only your wallet.

No over the counter drug will "blocks carbs." There is prescription drug that does, Acarbose (Brand name Precose) but the side effects of this drug are horrendous gas so bad that its maker, Bayer, stopped marketing the drug shortly after introducing it because even though it is mildly effective, no one would take it for very long. I could take one Precose a day and block about 15 grams of carbs, but quite frequently the gas would be very overwhelming. Unless you are all done with social life involving other humans, you probably don't want to block carbs.

If a "carb blocker" does not give you gas, it isn't blocking carbs, because any carbs that reach your gut not digested will ferment there thanks to the helpful bacteria we all have.

7. The Dirty Little Secret the Diet Books Leave Out

If you lose a significant amount of weight you will have to eat at a calorie level only one or two hundred calories higher than the calorie level you ate at to lose weight. All the studies show this to be true. It is the major reason that people are unable to keep off the weight they lose on diets.

So if you are serious about losing weight, you have to accept that the diet you'll have to eat for the rest of your life to maintain that weight loss will be one very much like the one you were eating while you lost the weight. In short, you'll have to stay on a diet for the rest of your life or all the weight will come back.

The people who profit from writing diet books rarely tell you this. They sell a ton of books to people who lose a ton of weight and then pack it right back on and become the market for New and Improved diet books by authors who pretend to have found yet another "diet secret." Even with those few books that do tell you this, experience shows that the readers ignore it, certain that THEY will somehow not find weight loss maintenance the problem that 95% of all other dieters have found it to be.

It's ugly, but it's reality. And if you want to lose weight and keep it off, you better take it seriously.

That's why it is a lot better to lose weight slowly but steadily eating a diet of foods you enjoy eating rather than going on any extreme diet which deprives you of things you love to eat. Do that, and you'll spend your diet looking forward to eating those foods as soon as the diet is over and when you burn out on dieting you will end up eating all those foods and they will pack the weight right back on.

If you are serious about weight loss, the diet is never going to be over.

Scams that Prey on People with Diabetes

It's time to hand out the lumps of coal. Here in no particular order are a list of scams that readers of this blog have asked me about.

1. Stem Cell "Cure" for Diabetes.

The weasels who run this one understand that most people know a lot more about Britney Spears' marriage than they do about science. They also know that you've heard dumbed down reports on TV about how stem cells might someday be able to cure diabetes. The result: an expensive scam that is 100% phony.

There is no technology available right now that will turn any stem cell into a beta cell. Just infusing a solution of stem cells into your body will NOT cause them to turn into beta cells, any more than swallowing a fertilized embryo would let you have a baby. End of story.

2. Herbal Substitutes for Oral Drugs or Insulin.

I get a lot of letters from people convinced that there must be some "natural" herb out there that will control their blood sugars and keep them from having to use oral drugs or insulin. Unfortunately, there isn't.

The oral drugs leave a lot to be desired, but at least when you take one of them you know what is in the pill and you can read peer-reviewed studies exploring what these drugs do. Herbs, in contrast, are completely unregulated and what little "research" there may be into the effectiveness of one of these herbs is almost always a tiny study funded by someone with a financial interest in the product that has been published in a vanity "Journal" which exists only to lend bogus credibility to what is actually an untested advertising claim.

Because there is no regulation of herbs and supplements most of the expensive bottles of supplements you buy--no matter who manufactures them--are full of mystery ingredients from from China and/or India including, at times, the toxins that notoriously pollute these countries' rivers and water supplies.

When these supplements are taken to the lab and tested, they frequently contain ingredients other than what are on the labels. More significantly, several "effective" herbal mixtures for diabetes sold in vitamin and "health food" stores have been found to be effective because they contain cheap first generation sulfonylurea drugs, which will lower your blood sugar dramatically--but which have been also found to cause heart attacks.

If you want to take a sulf drug, take a much safer second generation sulfonylurea drug like Amaryl. It is available as a generic for $4 at Wal-Mart. Why pay $30 for a bottle of chopped leaves and mystery sulf from China?

3. Sugar Free "Diabetic Foods"

Most of my readers know what a farce these are, but there are always new victims coming into the diabetes community who don't, to say nothing of their family and friends. I saw so many of these for sale this past Christmas season that I've concluded we can't warn people enough what a waste of money these are.

It isn't just "sugar" that harms people with diabetes, it is all carbohydrates. But almost all "Sugar free" and "Diabetic" products are full of flour and other starches. Most also contain maltitol or glycerine, which are not technically "sugar" but which break down into carbohydrates on digestion and can raise raise blood to surprising heights. If a "sugar free" food contains Lacitol, another sugar alcohol, it may not raise blood sugar that high, but it may give you a case of the runs that will ensure that your first experiment with "sugar free" products is your last.

If you are considering eating a "sugar free" or diabetic food, examine the nutritional panel closely and ignore any claim that the carbohydrates you see listed on it have somehow been magically relieved of their ability to raise blood sugar. It isn't true.

The one sugar alcohol that doesn't raise blood sugar is erythritol. Sadly, it can no longer be found in sugar free or "low carb" candies, probably because it was much more expensive than cheap maltitol. And even more unfortunately, though you can buy Erythritol at great expense in health food stores or by mail order, I have yet to find any recipe where the stuff you can buy is able to substitute effectively for sugar. It appears to need industrial food science techniques to work properly in candies.

This is only a start. What scams perpetrated on people with diabetes have you observed lately?

No Food has Carbs on Christmas!

It's only a matter of time until the Journal of Irreproducible Results publishes definitive proof of something we have all known: food eaten at Christmas and on New Years Eve contains no carbohydrates. This will be accompanied by a major long term study that shows that dieting during the holidays causes heart disease.

In fact, it's been a pretty good year for cheering dietary news. Peer reviewed research has confirmed that, for those of us getting on in age, being overweight is far healthier than being slim. There's evidence accumulating that eating saturated fat prevents stroke, and Gary Taubes has proven beyond doubt that the bad rap of sat fat stems from researchers a) confusing it with trans fat and b)blaming fat for the effects of the high carb side dishes people ate with their fats, and c) fudging their results.

Chocolate has made it into the ranks of health food. Soy has been shown to be the nasty poison it tastes like and someday it will be relegated to the ranks of other disgusting and worthless "health foods" like the blackstrap molasses and brewers yeast so beloved by health nuts in my youth.

So enjoy your holiday!

Food does have carbs the week after the holidays, and if you find yourself having a tough time getting back on track after the holidays are over, here's a page that has some tips that will help you get back into control: When You Crash Off Your Diet

One in six doctors is addicted or a drunk. Is yours? You'll never find out!

Buried in all the seasonal holiday cheer is this disturbing news story:
AP News: Programs Let Addicted Docs Practice

It blows the whistle on the way that the medical community protects its image by allowing doctors who are seriously impaired to continue practicing. It discusses how even when local medical associations know that a doctor is impaired and offer that doctor treatment for serious addictions or alcoholism, these organizations keep this information secret and allow the doctors to continue treating patients while undergoing rehab--even though, like so many other people in rehab, many doctors in rehab do not cure their addictions.

The article focuses on the major horror stories: obstetricians who kill babies by accident because they show up at the delivery drunk. Plastic surgeons who maim and mutilate their patients. Doctors who have a string of malpractice suits behind them along with drunk driving convictions who continue to attract new patients who have no way of finding out how dangerous they are.

There are a lot of these people. I grew up in a hospital family and I remember hearing my parents discuss the brain surgeon who operated drunk. But they liked him and it would never have occurred to them that they should have been demanding that the hospital administration for which they worked should pull this guy's license to operate. They just warned their friends not to go to him if they needed surgery. The rest of his patients? Well they were out of luck.

I remember being horrified when I heard this, but in all fairness to my parents, if they had made an issue of this man's impairment, or God forbid gone public with it, they would have been likely to have lost their jobs. That was how it was 40 years ago and that is how it is now. I later had a friend who was an M.D. who did have the courage to blow the whistle on another doctor at her hospital who had severely physically abused his wife, who was her patient. She lost her job. He kept his.

Perhaps the scariest thing in today's AP story is the statistics given about how common substance abuse is among doctors. The story cites statistics I've seen elsewhere that estimate that between 10 and 15% of ALL doctors have substance abuse problems. These statistics come from medical associations. Of those who are drunk or addicted, the estimate is that only 1% enroll in treatment programs. Meanwhile all these impaired doctors continue to treat patients who have no way of knowing how dangerous they may be.

Apparently, doctors cover for these guys out of the belief that its better to have patients die than to tarnish the reputation of the medical profession. But horror stories like these hide a much more pervasive problem. Doctors also cover for peers they know to be incompetent for reasons other than drug or alcohol abuse.

They know that colleagues may be giving outdated treatments. They know that some of the older practitioners may be in the early stages of dementia. They know that there are local endocrinologists who haven't a clue about how to prescribe insulin or thyroid medication. And they know, too, when a lot of their patients are coming down with MRSA in local hospitals. (There is no requirement that any hospital report the incidence of MRSA or other hospital borne infections to anyone.)

In short, the medical community knows a lot about the really bad medical care available in their regions. But they do nothing about it because far stronger than the Hippocratic Oath is the Physician's Code that says, "Speak No Evil of a Colleague." If the choice is your health or their profession's reputation, you're out of luck.

So ask your self this: If as many as one in six doctors may be practicing impaired, what percentage of doctors is giving substandard care?

How many prescribe expensive new drugs whose side effects are poorly understood because drug companies reimburse them for every new prescription written as part of a phony "study?"

How many ignore it when patients report severe side effects after they have been put on a new drug because they don't pay any attention to even the Black Box warnings flagging potentially deadly side effects of these drugs?

How many have set up their offices so that LPN "nurses" with a high school education and a certificate from a Junior College screen all patient calls and let these LPNS decide whose messages get passed on to doctors--in whatever garbled form the poorly educated, poorly paid clerk sets them down.

How many doctors are putting all their efforts into building up money making side line businesses like "laser hair removal" and other unregulated plastic surgery procedures instead of worrying about their patients' health?

When you read about the prevalence of impaired or incompetent doctors, you probably think that it this is someone else's problem. Your doctor is such a nice guy. Well, so was that brain surgeon who operated drunk. The fact is, you aren't likely to learn who the incompetent or dangerous doctors in your area are until you become their victim. Even if every doctor in your community knows who these people are.

Squeaky Wheels Needed at the Hospital

Last week I managed to inhale a piece of peanut. After 24 hours of croupy coughing my doctor sent me to the ER. I ended up hospitalized overnight, mostly because the doctor assumed that since I had diabetes I must be having a heart attack--which I wasn't. But during the night and morning I spent at the hospital the diabetes treatment I received was so terrible that I took my own advice and wrote a long letter to the Hospital's President and M.D. Patient care director detailing the problems with their diabetes treatment.

The problems I listed were these:

1. While each room had two brand new flat screen TVs, the blood sugar meter the nurse was using was a 5 year old Medisense meter that took a huge drop of blood, took 45 seconds to get a reading and was off by almost 50% from the value I got on my own Ultra 2 which had matched the previous night's lab draw very closely.

The nurse told me that my blood sugar of 79 was "heading for a hypo" and offered me orange juice when my Ultra read 115 mg/dl.

2. The nurse gave me a shot of insulin in a needle that must have been a 25 gauge or worse. It hurt like heck and left a huge bruise. Since many people's first exposure to insulin in in the hospital, I can see why so many Type 2s who first encounter insulin in the hospital will go to any length to avoid insulin.

3. The food I was given was from what called itself a "Carb Controlled Diabetes" menu. The "Control" in this case appears to mean that they made it impossible for you to eat anything BUT carbs. Breakfast offerings were French toast, pancakes, commercial breakfast cereal with extra high carb skim milk, toast and something they called "eggs" which when ordered turned out to be about 2 tablespoons of a powdered abomination that smelled strongly of sulfur and were so sickening I couldn't eat them. The toast came with a choice of low fat cream cheese, margarine or jelly.

To add insult to injury, when I asked for Peanut butter, what I got was fully hydrogenated and contained molasses. I was also told I could not have coffee with caffeine and when I protested the menu the Hospitalist M.D. assigned to my care lectured me about the importance of eating a low fat diet for the rest of my life to control my diabetes.

Well, I know that the hospitals in my region are locked in competition with each other for patients, because they run a lot of ads in the local newspaper touting their services. So I figured the best thing I could do would be to explain to hospital management why I was going to have to tell my diabetic friends that as far as this hospital was concerned "good control stops at the hospital door."

Yesterday I received a phone call from the M.D. in charge of their ER services who had been given my complaint by the head of Patient Care. He started off the conversation by telling me that his wife was a Pediatric Endocrinologist and that he had shown her my letter before calling me.

He said that she had thought my criticisms to be completely on target. She told him the Ultra was the most accurate meter available and that it was likely the old meters they were using were inaccurate. She added that she told her patients to bring their own needles to the hospital because the ones used there were so horrible, and she asked why the menu provided did not give the carb counts of the various foods and allow patients to eat at the carb level they were supposed to be eating at!

The doctor/administrator and I had a long talk, during which he accessed my What They Don't Tell You About Diabetes web site and I reminded him of the research showing the relationship of A1c and post-prandial blood sugar to heart attack risk and mortality (since he was an ER guy) and reminded him, too, of the WHI data that has discredited the low fat/high carb diet as a way of preventing heart disease.

He promised me that something would be done about the problems in his hospital that I'd identified and said that he would get back to me about the progress. I'm not hoping for miracles. They'll probably have to hear from a lot more patients before things change, and the quality of care in my region is such that most people with diabetes are still following the ADA's outdated advice that 180 mg/dl post meals is a great blood sugar and they are eating the ADA's sponsor's beloved high starch/high sugar diet so I don't expect a lot of people to complain.

But I learned a couple things from this experience:

1. Don't wait until you are in the hospital to find out what your local hospital's policy is about diabetes treatment--especially if you use insulin. Write a letter NOW to the M.D. administrator in charge of patient care at your local hospitals and ask them the following.

a. If I am hospitalized but conscious, will I be allowed to retain my own blood sugar testing supplies, and insulin needles? Will I be allowed to administer my own insulin using the doses I set? Will I be allowed to keep wearing my insulin pump?

I have heard horror stories of nurses removing pumps and giving generic insulin doses to people with Type 1. None of the nurses in my local hospital's cardiac ward had ever heard of the "insulin/carb ratio" nor did they know anything about Basal/Bolus insulin regimens. I was allowed to use my own Novolog pen, which I'd brought along, and to set my own Lantus dose (though they provided the Lantus which came in their railroad spike needle) but not all hospitals will allow patients to do this.

b. If I am not conscious, what is the blood sugar target your staff will use when administering insulin to me? Will they consult with my endocrinologist or PCP about my insulin dosing?

c. What kind of meters does your nursing staff use. How old are they? How often are they calibrated with the lab results?

d. Is your nutrition staff aware of the data that has emerged in the past decade which finds that the very low carbohydrate diet is both safe and very effective for controlling diabetic blood sugars? Do your nutritionists realize that the low fat/high carb diet can provoke dangerously high blood sugars in people with diabetes? When hospitalized will I be allowed to choose my own food or will I be forced to eat the discredited low fat diet that may raise my blood sugar to dangerous levels?

If you are told there is a "carb controlled" menu (as I was) tell them how many grams of carbs the nutritionists prescribe per meal, and state how many grams per meal you eat to maintain your currently excellent level of blood sugar control.

If every hospital started getting letters like this on a steady basis, things would change. I'm old enough to remember when hospital maternity departments actively discouraged new mothers from nursing. We La Leche League ladies changed, that, with a lot of letters, articles in the press, informational meetings with pregnant ladies, and public information campaigns.

Now its time for us folks with diabetes to take on the medical community by making it clear that we will not tolerate substandard care.

The peanut appears to have dissolved on its own. I'm not coughing, though I'm sure the sight of the bill I'm going to get (with my high insurance deductibles) will set me sputtering again. I will just have to write that off as "research costs" as this was educational and, I hope, may help some other folks get better treatment.

But don't wait until your gall bladder acts up or some imbecile rear ends you! Write that letter to your local hospital administration today and make it clear to them what kind of diabetes care you're looking for in the hospital you choose to patronize!

Actos is Dangerous Too!

If you follow the diabetes news, you probably saw reports today about a new study published in the Journal of the American Medical Association, this one, a study of the medical records of people over 65, is being reported as it if found that Avandia raised the rate of heart attacks and death. That is how the New York Times and many other news organizations are headlining this story. But that isn't actually what the study found. Here's a better report.

Study: Type 2 diabetes drugs raise heart risks: Chicago Tribute based on study published in JAMA

The crucial piece of information here is that, in a study of patient records of people over 65 taking various diabetes drugs both TZD drugs, Avandia and Actos, appeared to cause significant increases in death and heart problems.

I can't help but wonder if the way this story is being reported--with many news outlets making it sound like only Avandia causes excess heart deaths--is because Takeda, the maker of Actos, is advertising heavily in the media now that Avandia has been so thoroughly discredited. Are the media downplaying the suggestion that Actos too may be dangerous to keep this big-money advertiser?

In reports like those of the New York Times the article claims that Avandia alone is identified as dangerous because most of the patients taking TZD drugs in this study were on Avandia so there wasn't enough data to draw firm conclusions about Actos.

But we know that Actos, like Avandia, causes heart failure. It carries a black box warning to this effect in its prescribing information, as required by the FDA.

Heart failure means that the muscle of the heart has weakened. Research has found both TZD drugs appear to cause heart failure in people who did not have it before starting the drug. This may be because Avandia and Actos can cause intense water retention and swelling, which can stress a marginal heart.

We also know that Actos, like Avandia, causes thinning of bones leading to osteoporosis and fractures in older women. I discussed that in this previous blog post.

Sadly, most doctors have responded to the media blizzard of bad news about Avandia by switching their patients to Actos. That is probably because they don't have the time or inclination to research the safety of Actos on their own and depend too heavily on media reports and drug company salespeople for guidance on what drug to prescribe.

ADA Won't Recommend Against TZDs
In related news, Diabetes in Control reports that the latest ADA practice recommendations still recommend TZD drugs, despite the evidence against them.

This should come as no surprise, given the huge contributions the drug companies make to the ADA and the long track record the ADA has amassed of working to ensure that people with diabetes eat high carb diets full of their sponsors' junk foods that raise their blood sugar so that these patients need to take their other sponsors' expensive (and dangerous) drugs.

The ADA really should be renamed, "The American Association of Those who Profit from Diabetes." That is who they serve, not the people who HAVE diabetes.

What Does This Mean For You?
If you are a person with Type 2 diabetes you need to understand that both Avandia and Actos work by affecting the PPAR-gamma receptor. They both cause water swelling and this swelling is probably what strains the heart. They both also cause dramatic weight gain, because the way that they appear to work is that they push the body to create new fat cells which lower blood sugar by storing excess glucose in the form of fat in those new fat cells. They weaken bones because the receptor they affect also controls the rate that the body destroys bone cells, and the way they affect it makes for more bone destruction.

The drug companies claimed for years that both these drugs rejuvenated beta cells. This has never been proven. They also claimed that these drugs lessened the amount of metabolically dangerous belly fat. This to turned out to be a result of (intentional) misrepresentation of data. The ratio of belly fat to butt fat decreases with these drugs--but only because these drugs pack so much more new weight on the butt!

Meanwhile, with none of their supposed benefits proven--the ones that motivated doctors to put so many people on these expensive drugs--the heart and bone problems of these drugs have become apparent.

If your doctor assures you Actos is safe, remind him or her that it causes the same increase in heart failure as Avandia and causes the same bone thinning. Remind him or her that the only reason we don't have as much data pointing to the dangers of Actos the way we do about Avandia is that it never has had the market penetration or scrutiny that Avandia had.

Will we ever know the truth?
It's very unlikely Takeda will be funding any large scale controlled studies investigating the safety of Actos. Why kill the goose laying the platinum eggs? No one else has the kind of money it takes to fund the kinds of studies that will discover the long-term health damage Actos causes. And even if they do, do you really want to take this drug for the 10-12 years it would take for the real cost of using it to be proven beyond doubt--years during which your bones erode, new fat cells accumulate, fluid build up and stresses you heart, and who knows what is happening to other parts of your body that use this same PPAR-gamma receptor?

Let's Get Back to Basics
The reason we lower our blood sugars is to maintain our health. Any drug that improves blood sugar by increasing mortality is a bad drug. Any drug that improves blood sugar by causing osteoporosis--a major killer of older women--is not a good drug.

And the really sad part is that neither Avandia OR Actos lower blood sugar all that much. The typical A1c drop people see when taking this drug is around 1%--but that is when their A1c starts out at 9% or 10%. And the price people pay for this very small decrease in A1c is to pack on weight--in the form of new fat cells--that does NOT go away even if they stop taking the drug.

It is all so unnecessary! I get mail all the time from people who have brought their A1cs down from as high as 16% to the 5% range simply by cutting down their carbs to where they no longer are spiking over 140 after a meal.

This strategy has no dangerous side effects, and the only people who will tell you that cutting carbs is dangerous are those who are ignorant of the findings of current medical research.

As long as you eat enough protein, your body can manufacture every one of the grams of glucose your brain needs. Any dietitian who does not know this is ignorant and dangerous. Lowering your carbohydrate intake to where your blood sugar is normal or near normal will also improve your lipids. And low carb diets will not damage your kidneys unless, perhaps, you have end stage renal disease. Again, anyone who tells you differently is merely repeating old wives tales and is not familiar with what science has found.

The key to safety with low carb dieting is that you have to cut your carbs low enough to keep your blood sugars in the normal zone--under 140 mg/dl. Do that, and you will see dramatic improvements in your A1c--improvements much better than what you can get with either Actos or Avandia.

And if you do need a drug to lower your insulin resistance, Metformin has a much longer history of safe use and it is more effective than the TZDs.

If you can do it, regular exercise may also improve your insulin resistance better than TZDs.

There is simply no reason to take a drug that will erode your bones, strain your heart, and make you fatter, when there is a much safer way to control your blood sugars.

Bad Science: Study Published as Suggesting Byetta Can Replace Insulin Shows Opposite

UPDATE (April 2, 2013): Before you take Byetta, Victoza, Onglyza, or Januvia please read about the new research that shows that they, and probably all incretin drugs, cause severely abnormal cell growth in the pancreas and precancerous tumors. You'll find that information HERE.

Original post:

Study after study shows that Byetta is not the wonder drug that its manufacturer would like you to believe it is, but that doesn't keep the drug company from spinning the results of their disappointing studies.

Here's the abstract of this new study which was preformed by researchers who were forced to disclose that they were funded by the makers of Byetta:

Exploring the Substitution of Exenatide for Insulin in Patients With Type 2 Diabetes Treated With Insulin in Combination With Oral Antidiabetes Agents

It concludes "it is feasible to sustain glycemic control when substituting exenatide for insulin". But a closer look at the study finds that this is NOT at all what it really found.

First of all, the researchers stacked the deck for Byetta by comparing Byetta with insulin used incorrectly. To quote an editorial published besides the study "the insulin regimen used in this study was often non-physiological and that no attempt was made to optimize insulin therapy before substituting exenatide."

Secondly, even when compared to those using poorly prescribed insulin regimens, the people taking Byetta saw their A1c deteriorate and suffered many more side effects.

This doesn't stop the people who profit from Byetta from touting the idea that their study "proves" that expensive Byetta can be substituted for insulin.

You can bet your bippy drug company reps will be telling your doctor that these exciting new results mean they should move patients on insulin to Byetta.

If your doctor tells you this, call him or her on it and ask why they haven't looked at the actual data. You might also cite the conclusions published in the accompanying editorial by Drs. Julio Rosenstock, of the Dallas Diabetes and Endocrine Center, and Vivian Fonseca, of Tulane University, New Orleans, who were not funded by the makers of Byetta.

They wrote, "The overall effect on glycemic control was rather disappointing. ...this was clearly a negative trial, with a flawed study design and a conclusion that perhaps should have been stronger against substituting exenatide for insulin."

Avandia Causes Osteoporosis and Broken Bones--But Actos Does TOO!

This week's medical news is full of reports about a study that explains why Avandia causes osteoporosis.

Here's a report that gives more than the usual amount of detail about this study:

Avandia Researchers Find Reason Behind Bone Fracture, Osteoporosis Side Effects

I have already blogged about Avandia's connection with a doubling of the incidence of fractures this last year HERE.

But what concerns me now is that the way this new story is being reported makes it sound as if the osteoporosis is only a side effect of Avandia, a drug that for all practical purposes is dead after the press discovered the long-known fact that research proved it increases heart attacks.

But as the article I link above makes clear, the reason Avandia causes the bones to thin is because of the way it affects the PPAR-gamma receptor. To quote the report cited above, "the new research found that Avandia also appears to affect a key cellular protein called the peroxisome proliferator-activated receptor (PPAR-gamma). In their study, the California team discovered that activating this receptor in mice also stimulates the production of osteoclasts, cells whose key function is to degrade bone."

Those of you who study diabetes drugs know that it is NOT news that both Avandia and Actos stimulate PPAR-gamma. In fact, this PPAR-gamma stimulation has been the mechanism used to explain how these drugs work ever since the drug companies started selling them over a decade ago. So this finding that Avandia's effect on PPAR-gamma destroys bone suggests strongly that Actos, too, may cause osteoporosis and fractures.

The way the media has spun the Avandia story until now has been that Avandia is bad but Actos, its competitor, is still a good choice. But this new finding should make us think twice about using Actos at all.

The prescribing information for Actos clearly cites that osteoporosis and a doubling of bone fractures has been found by research to be an Actos side effect.

Here is what the FDA-mandated Prescribing Information for ACTOS tells us:

Fractures: In a randomized trial (PROactive) in patients with type 2 diabetes (mean duration of diabetes 9.5 years), an increased incidence of bone fracture was noted in female patients taking pioglitazone. During a mean follow-up of 34.5 months, the incidence of bone fracture in females was 5.1% (44/870) for pioglitazone versus 2.5% (23/905) for placebo. This difference was noted after the first year of treatment and remained during the course of the study. The majority of fractures observed in female patients were nonvertebral fractures including lower limb and distal upper limb. No increase in fracture rates was observed in men treated with pioglitazone 1.7% (30/1735) versus placebo 2.1% (37/1728). The risk of fracture should be considered in the care of patients, especially female patients, treated with pioglitazone and attention should be given to assessing and maintaining bone health according to current standards of care.

Note that these studies only lasted a few years. Over time it is likely that a higher incidence of broken bones and osteoporosis would be found with this drug. Men have thicker bones than women and it would take longer for bone thinning in males to be diagnosed.

Bottom line: Broken hips are one of the biggest killers of older people whose bones naturally thin with age. Hastening the degeneration of your bones is suicide. Don't take either Avandia or Actos. These drugs do not provide anywhere near enough benefit to outweigh their dangerous side effects.

Special strains of acidophilus fight yeast and adjust pH

I'm really happy to note that last week the New York Times wrote a long article praising Good Germs, Bad Germs: Health and Survival in a Bacterial World by Jessica Snyder Sachs, which I reviewed here enthusiastically a few weeks ago.

In the discussion of how we can harness other microorganisms to fight the harmful ones in our bodies, Sachs's book contained what the medical newsletters call a "pearl for practice", one which I tested out myself with excellent results.

Sachs discussed a product, Fem-Dophilus, that contains strains of acidophilus which are those that naturally colonize healthy female reproductive and urinary tracts. After killing off our own friendly acidophilus by using antibiotics, many of us have attempted to introduce acidophilus using yogurt, but it turns out that the kind of acidophilus found in yogurt is a different strain that does not flourish in our bodies for any period of time.

The benefits of having the right strains colonizing your body are that they outcompete yeasts and the bacteria that cause bacterial vaginosis by giving you the correct pH and secreting high levels of hydrogen peroxide that kill other microorganisms.

As those of you who read my blog know, I'm not a big fan of supplements, but I read enough user praise for Fem-Dophilus online to think it was worth a try. I bought it mail order. Buying it that way costs half of what you'll pay in local health food stores even with postage. I have been using it for three weeks.

It really works! Many, if not most, of us older ladies whose hormone levels have dropped have problems maintaining normal vaginal pH. If we have high blood sugars, we may be very susceptible to yeasts or other hostile microorganisms. Even if we have normalized our blood sugars if we had frequent urinary tract infections before diagnosis, we may have fatally screwed up the natural flora in our guts and vaginas.

I've gone through a lot of antibiotics in the past, because my high blood sugars gave me unrelenting urinary tract infections which resulted in some scarring that makes new infections even more likely to occur. After three weeks of introducing these friendly bacteria into my system, I am experiencing improvements in both digestion and in pH-related issues that are quite encouraging.

So if you are a woman who has been battling urinary tract infections or vaginal dryness investing in a bottle or two of this stuff might be well worth a try.

To update my report on another helpful supplement: Vitamin D.

After a brief period I stopped seeing any blood sugar effects from Vitamin D, but I did noticed that I seemed to be more cheerful than usual and when I stopped taking it I found that the mood effects wore off. They came back when I started it again. I think that the initial burst of cheerfulness many of us experience when going out on a sunny day may be connected with our body's pumping out some Vitamin D in response to the sun exposure. (If you are like me and have very pale skin, that cheerfulness turns to dismay as you almost immediately afterwards redden up and everything starts to burn!)

Vitamin D seems like it might be a very good supplement for people with diabetes to take, as it might be related to the depression that has been observed to accompany diabetes--along with the lowered Vitamin D levels.

One caution though: I read that if you don't take calcium WITH your Vitamin D, it may actually promote the storage of other metals in your bones--the ones you are getting in polluted air, Chinese supplements, and foods. So don't take Vitamin D without calcium. Cheese and other food sources are best. I use the kind of supplements that are mostly ground up limestone.

Lessons for the Diabetes Community from the Cancer World

I just read a very disturbing book, The Secret History of the War on Cancer by Devra Davis. Suffice it to say that if you are easily scared, you should not read this book.

Dr. Davis is a distinguished epidemiologist. Her subject in this book is how the companies that profit from selling cancer causing products coopted the very organizations and government organs set up to "fight cancer." She describes how the American Cancer Society was taken over by people from the tobacco industry who used the mantra, "This needs further study" to keep the organization from letting the public know that as early as the 1930s scientists had proved very conclusively that cigarettes caused cancer, and that the more a person smoked the more likely they were to develop cancer.

The tobacco industry provided a great deal of funding for the American Cancer Society and one way it kept the public from learning how dangerous their products were was to fund research into other obscure causes of cancer, which was done to downplay the role their product was playing in the huge rise in lung cancer that followed the addiction of millions of soldiers to cigarettes in World War I.

An even more disturbing finding that Davis documents is the way that industries that produce cancerous chemicals have for decades paid researchers to research the cancer causing properties of their products and the chemicals used to make their products, but kept their results hidden from the wider scientific community. Companies have known for decades that workers in their plants were dying horrible deaths from exposure to chemicals used in their workplace, but kept this secret. In some industries, chemicals were used that caused 100% of all workers to get cancer after 25 years on the job. Nevertheless though scientists working for these companies knew this, the information was kept completely secret, because revealing it would reduce corporate profits. That people died because of the secrets they kept was just too bad.

What does this have to do with diabetes?

Well, the ADA has had the same role in the diabetes world that the ACS had in the cancer world. Funded largely by companies that make the high carb products that worsen blood sugar and the drug companies that profit mightily when people eat those products, the ADA has fought for decades against letting the public know that it is carbohydrates that raise blood sugar and that people with diabetes can control their diabetes by lowering their carbohydrate intake substantially.

Any time research proves that cutting out most carbohydrates from your diet--especially those supposedly "healthy whole grains"--improves the health of people with diabetes, the ADA says, "More studies are needed." Meanwhile they put their stamp of approval on high carb junk foods made by companies like Campbells "One gram of salt per serving" Soup.

The ADA has put millions of dollars into convincing people with diabetes that sugar is good for them. Not so coincidentally a top ADA sponsor is Cadbury Schweppes, the candy and soda maker. Check out the annotated list of ADA sponsors as of August 2006 . The company has removed the list of sponsors from the page linked on that entry, probably because it was so damning. But their sponsors continue to be companies that sell you food that makes you more diabetic or expensive drugs you will need if you eat that kind of food.

Like the American Cancer Society, the ADA raises huge amounts of money from the victim of the disease their policies have made more widespread. These donors do not realize that just as the ACS's leadership was full of chemical industry and cigarette company lobbyists, the ADA's leadership is not made up of people with diabetes or of doctors, but of laymen whose corporate connections are not made public, but who probably have long histories of connections with the drug and junk food companies.

Just as the ACS kept the public from knowing for 20 years that cigarettes caused cancer, the ADA has fought to keep you from knowing that it is carbohydrates that raise blood sugar and that a "healthy diet" for a person with diabetes is one that does not raise the blood sugar over normal limits.

Recently a news release went out to say that the ADA has decided to soften its long held hostile stance against recommending low carbohydrate diets for people with diabetes. Well, don't get your hopes up. The outcry against their dangerous and outdated dietary advice has gotten so loud they have to do some kind of spin control. But a "diabetes" organization that in 2007 still defines "tight control" as a blood sugar that drops to 180 mg/dl (10 mmol/L) at 2 hours after eating, and does not mention the word "carbohydrate" once on their Tight Diabetes Control web page is not about to tell anyone to stop eating the diet that is killing them. Not when the funds that pay the salaries of the mystery people who run the organization are paid by huge corporate junk food and drug makers.

The venality documented in Davis' book is terrifying. I had naively thought that the mess that is diabetes treatment was the result of our having a non-glamorous disease people think is caused by our own bad habits. Davis' book makes it clear that callous disregard for the public, deceptive advertising, and cooking the research to hide results that might cost some company money are standard operating procedure throughout the health establishment.

The end-of-life repentances of the cigarette and chemical executives who spent their lives misleading people about the safety of their products do not begin to atone for the hundreds of thousands of people they killed. Will the ADA executives and their self-serving sponsors who fund the organization to ensure that their products continue to find a market, ever come to grips with the way they have caused generations of Americans to go blind, lose their feet, and go on dialysis?

Probably not. After all, unlike those cigarette industry folks who eventually got cancer from their own product, the ADA denizens don't have diabetes, they only profit from it.

Great Diabetes Gift!

I just got the diabetes bag I ordered only two days ago from Rickina at Stick Me Designs.

It is even nicer than I expected it to be. I can stuff every possible diabetes supply I can think of into this bag and still get it shut.

Here's a photo:

Needles, pen, pen needles, insulin vial, meter, lancet, strips, even my handy dandy needle snipper, all fit in. And with all this stuff in the bag, it still closed:

Rickina, who recently went through a diabetic pregnancy which made her realize the need for this kind of bag, makes these herself. I also sew, and I can tell you, her work is beautiful.

You could also put your glucose in one of the zippered compartments, or your house keys wallet and money, for that matter. It would also be perfect for putting in a larger handbag or for when you travel and want to be sure you have all your stuff with you as carry on.

Most of all what I love is how jaunty it is.

Way to go Rickina!

When to Test Blood Sugar in Type 2

One of the topics that comes up a lot in the email I get from visitors to my What They Don't Tell You About Diabetes web site is the question of when is the best time to test your blood sugar.

A lot of doctors still tell people with Type 2 to test first thing in the morning and before meals. That was what I was told at diagnosis in 1998. People who test using this schedule may tell you their blood sugar is usually 120 mg/dl, which sounds pretty good, except that since this is a fasting number it usually hides the information that the person's blood sugar maybe going to 250 mg/dl or higher after every meal.

Research has shown that for people with Type 2 diabetes--especially those who have been diagnosed recently and still retain some beta cell function--it is the high spikes after meals that contribute most heavily to raising the A1c and causing complications. If you only test your fasting blood sugar, you will not know anything about how high your blood sugar is spiking after meals, so you won't know which foods are toxic to you because they cause dangerous spikes.

If you are like most people with Type 2 your access to the very expensive blood sugar testing strips is limited. You may have to pay for strips yourself or your insurance may pay for a single box each month. That means that you need to use each strip as efficiently as possible. Here are some strategies that you can use to get the information out of your blood tests that will let you drop your A1c back into the healthy zone.

  1. Keep a written log that matches what you eat with the test result you get.
    Even though your meter may keep a list of your readings, these readings are meaningless unless you know what food you ate that resulted in each particular reading. If you write down what portion size of which food you ate and match it to the blood sugar you saw after eating it, you will accumulate the information you need to eliminate toxic foods and replace them with those that do not raise your blood sugars.

  2. Determine when your blood sugar reaches its highest point after eating.
    Your goal is to bring your blood sugar peaks below the level that we know cause complications. To do this, you need to learn when your blood sugar hits its highest level. Research studies show that the average person sees a blood sugar peak 75 minutes after eating carbohydrate.

    But you're not average, you're you. So the first thing you need to do is determine when your own blood sugar peak occurs. Start out by testing at 1 hour, 1.5 hours, 2 hours, and 3 hours. Do this for three meals. You should start seeing at which time the highest reading occurs. That's the time you should plan to test in the future.

    Don't test at 30 minutes after eating. Though many people see a high at this point, research has shown that brief peaks at 30 minutes after eating do not correlate with an increased incidence of complications. The one hour reading is the earliest that you should concern yourself about.

    If you eat pasta which digests very slowly you may see a peak much later than usual. You should test for peaks from pasta 4 or 5 hours after eating if you don't see them in the first 3 hours.

  3. Eliminate the Foods that Cause Unacceptable Spikes.
    You can test all you want, but if you don't use the test result to eliminate the foods that cause blood sugar spikes, you might as well not test at all. Testing is the most powerful tool you have as a person with diabetes to regain your health, but you must act on the information you get from your testing.

    If you see an unacceptable high blood sugar reading, the only way to bring it down is to cut back on the amount of carbohydrate in your meal. Carbohydrates are what raise blood sugar, and despite what you may read in books written by people who do not have diabetes, every gram of carbohydrate you eat will raise your blood sugar no matter whether it is supposedly "healthy", "low glycemic" or the label says it is magically treated to keep it from raising blood sugar.

    So if your blood sugar is too high after eating a meal, determine where the carbs came from that raised your blood sugar in that meal, and cut back on the carbohydrate food or eliminate it completely.

  4. Nutritional Software Can Help You Discover Where The Carbs Are
    I like LifeForm. Others use Fitday. Find a reliable source of nutritional information and look up the foods you eat to see where the carbs are coming from. Read the labels on the prepared foods you buy and be careful to note the portion sizes which are almost always much less than you eat. For example, have you ever gotten "2.5" servings out of a can of Campbell's soup? No. I didn't think so. But that's the portion size given on the label, so if you eat half the can, you're getting 20% more carbs than are listed on the label.

  5. Shoot for Healthy Blood Sugar Targets
    These are the targets that will give you an A1c in the 5% range no matter how high your A1c is now. If you don't believe me, check out THIS PAGE of reports from people who have used these targets to dramatically lower their A1cs.

    One hour after eating: under 140 mg/dl (7.8 mmol/l)

    Two hours after eating: under 120 mg/dl (6.7 mmol/l)

    If you can do better than this, go for it. Normal people rarely go over 120 mg/dl ever and are usually under 100 mg/dl at 2 hours after eating.

  6. Use Generic Meters and Strips if Access is Limited

  7. Wal-mart sells the Relion meter for $8.88 and the strips are less than half the price of the name brand strips. They work just as well. The drugstore brand meters made by TrueTrak are also much cheaper than the brand name strips, though the strips may lose their accuracy over time, once the vial is opened. Companies give away "free" meters only to get you using their overpriced strips. Don't pay full price for name brand strips. It isn't necessary. You can sometimes get good deals on strips on eBay but check the expiration date. Don't buy expired strips and don't buy strips by mail when it is hot as the heat can destroy them.

Study: Studies funded by Drug Makers Underestimate Problems

Today's New York Times drew my attention to this study:

Adverse Effects of Inhaled Corticosteroids in Funded and Nonfunded Studies

It looked at studies of inhaled drugs and found two phenomena that should surprise no one who follows the news about any new drug.

1. Studies paid for by the company making the drug found far fewer side effects than studies of the same drug paid for by organizations that had no financial stake in the drug. The drug maker's studies were much more likely to describe a drug as "safe" or "effective" than were other studies.

2. The reason for this lay in the way that the studies were designed which appeared to make it easier to hide the side effects.

What's crucial here is that the misleading studies funded by the drug makers included the clinical trials used to get approval for the drug.

This should remind you that all the studies done to get approval for a drug are paid for by the company who will profit (greatly!) from the drug's sale. But this system ensures that the studies will be cooked as far as possible.

What does this mean for you? Simply this: for chronic conditions it makes sense to avoid new drugs no matter how well hyped until they've been in the marketplace for enough time that their real side effects will become apparent.

And don't trust those company funded studies that "prove" that the drugs cause much-yearned for benefits like weight loss or beta cell regeneration. Almost always these benefits disappear when the drug is studied by someone who isn't going to profit from its sale.

Debugging the Highs: Update

Well, I went through my debugging sequence as I described in a previous blog entry and the news is not good.

I am responding completely differently to R insulin than I was just three months ago, which is the the last time I was not taking Metformin.

My response to the R insulin was so different from what it was 90 days ago, that I went so far as to drive to a Wal-mart pharmacy in a different state and buy a new vial of R there, just to make sure that the two week old-vial I was using didn't have something wrong with it. The previous vial I'd bought at my usual pharmacy was the same lot as the insulin I'd bought a couple months before and I wondered if perhaps it had weakened.

To test the potency of the new insulin, I ate the identical meal for dinner using the same dose of the new insulin as I had eaten the night before with the dose from the older vial. I ended up with a blood sugar reading only 5 mg/dl different at one hour from what I'd seen the previous night. Unfortunately, that reading was 178. And that was with 4 units of insulin, which is a lot for me. This was using a 1/12 insulin/carb ratio which was what I would have used before when not taking Metformin.

Yesterday tried using a 1/8 insulin ratio, and it worked okay at lunch with 25 grams of carbs, though not great. But when I tried it at dinner with 40. I ended up at 157 at 1 hour and 126 at two.

That doesn't sound too bad, but there's a hitch: Eventually the insulin IS kicking in and I'm going low. After my meals yesterday I ended up in the low 80s feeling shivery--and after eating more fast acting carbs I was still in the 80s an hour later.

This sounds like what happens when a person has developed antibodies to insulin. The insulin is bound by the antibodies for a while making it less effective, then the antibodies release it and it kicks in later.

If that is my problem, the only thing I can do is wait it out and hope it goes away. Needless to say, I'm going to have to cut way back on carbs because I am going too high after meals, staying high and then getting lows, which make me feel like crap all day long.

If any of you have had anything like this occur, let me hear about it.

Halle Berry: Poster Girl for MODY?

There's been a huge outcry online now that Halle Berry, previously a poster girl for Type 1 diabetes, has told the press that she has been able to wean herself off insulin.

A lot of people with Type 1 diabetes are very upset with this for the very understandable reason that it is impossible to go insulin if you have Type 1 diabetes unless you get an experimental pancreas or beta cell transplant--and even those are iffy. So there are a lot of people with Type 1 who are feeling betrayed and that is making for a lot of anger.

In fact, what happened to Berry has happened to quite a few people who have emailed me over the years since I put up my web page about monogenic diabetes (MODY).

None of them are TV or movie stars, so their experiences didn't hit the media. But all of them were diagnosed with Type 1 diabetes in their late teens or early 20s only to find out years later that they actually had a genetic form of diabetes that keeps beta cells from secreting--a form of diabetes where it is possible to reestablish beta cell secretion using sulfonylurea drugs like Amaryl or, more recently, Byetta instead of, or in combination with, insulin.

While some forms of MODY, like the one I appear to have, are mild enough to be misdiagnosed as Type 2 diabetes, as mine was, others can be quite severe and easily confused with Type 1 diabetes. Here's a case history of just such a case:

Identification of MODY: the implications for Holly
Journal of Diabetes Nursing, Jan, 2004 by Jo Dalton, Maggie Shepherd

The main things hinting that MODY might be at fault here were that insulin doses remained in the "honeymoon" range, years after diagnosis and that the patient did not develop DKA. Note also that the patient's father was diagnosed with "Type 2" later in life, but actually had a much milder form of the same genetic diabetes. The virulence with which these gene express is modified by many environmental factors science does not yet understand.

Many doctors still believe, incorrectly, that a person cannot develop MODY unless one parent has been diagnosed with diabetes. But even though neither of Ms. Berry's parents was diagnosed with MODY it does not rule out that she might have inherited the gene from one of them. In addition, as in the case of Holly's father, the gene may spontaneously mutate and appear in a person with no relatives with diabetes.

That there are "silent" carriers of these genes scattered through the population was only realized recently when scientists started testing family members of people diagnosed with MODY via gene tests. They discovered that there were other people in the families who were carrying MODY genes but whose blood sugar abnormalities had escaped diagnosis--probably because, like mine, the gene defect affected only post-meal blood sugar levels and were not detectable using a fasting plasma glucose test.

It is also worth noting that scientists who study genetic diabetes believe there are many more genes out there causing insulin secretory disorders than the six that have been so far identified. So it is possible that there are a lot more people diagnosed as Type 1 diabetics who have one of these not yet diagnosed genes.

However, it is also very important to note that whatever the cause of the defect, these MODY forms of diabetes are every bit as capable of wreaking havoc on eyes, nerves, and kidneys as is Type 1.

As far as Ms. Berry's situation goes, I hope that she isn't settling for the 7%-8% A1c that so many doctors consider good enough for someone with Type 2. As exciting as it might be to be able to give up insulin, trading shots for blood sugars high enough to cause blindness, amputation, and dialysis is not such a smart idea.

Ms Berry still has diabetes, it still has the potential to ruin her life, and she still needs support from the rest of the diabetes community in learning how best to get her blood sugars down into the normal range so she can avoid developing complications.

And we all need to realize that Ms. Berry's situation points out how misleading are the current diagnostic criteria which lump hundreds of different genetic and metabolic disorders into one of two bins--Type 1 and Type 2.

"Overweight" is Healthiest Weight

This is not actually news, as there was a good study published some years ago that found the very same thing to be true, but a new study presented at this years American Heart Association meeting confirms the finding, and has led to some headlines on the topic.

The basic message here is that you are most likely to live a long and healthy life if your BMI is between 25 and 30, which for a 5' 4" woman means having a weight of 150-174 lbs and for a 5' 10" man is 175 - 208 lbs.

Here's a report on the finding from the New York Times.
Causes of Death are Linked to a Person's Weight

Here are some earlier large population-based studies that have found similar results:

From JAMA in 2005 based on NHANES III data

Here is a further review of the NHANES data that points out that over age 70, overweight AND obesity are more healthy than normal or underweight. Be sure to scroll down to Table 4.

Supplemental Analyses for Estimates of Excess Deaths Associated with Underweight, Overweight, and Obesity in the U.S. Population
by Katherine M. Flegal, Ph.D.

The current data does NOT break health down by decade, which is a shame, because the strongest signal in the NHANES study points to weight becoming increasingly healthful as we go through middle age. By not breaking mortality figures out by age, we may miss this vital point.

This data flies in the face of our society's obsession with thinness and its tendency to equate near-anorexia with moral superiority and overweight to sinfulness. However, as anyone who is over 50 knows, at middle age the body ramps up its weight gaining mechanisms to the point where it is almost impossible NOT to gain weight. Now this research suggests that there is a reason for it, and it is not that we suddenly become lazy, greedy slobs.

As we age, the metabolism slows down at a predictable rate. The result of this slowing is that at 59, I can now gain weight eating the same diet that I would have lost weight on at age 40. A diet, by the way that has the same number of calories used to induce starvation in men who averaged a weight only 10 lbs more what I now weigh during Ancel Keye's famous WWII Starvation Experiment.

This is not because I am less physically active than I was at 40, which is the usual excuse given for middle age weight gain. No, my body has clearly decided that I need an extra 20 lbs and the more I fight it the harder it fights back.

So what a sudden revelation it is to realize that maybe my body is doing this because it is trying to keep me alive!

There is a predictable backlash to this data from people who know it has to be wrong. But as the analysis of the NHANES research linked above shows, their belief that overweight is unhealthy may derive from studies that cherry-picked the data in such a way as to achieve the result that the researchers already believed to be true. Taubes' work has made it very easy to see how common this is in so-called scientific studies.

And it's also worth remembering many of the claims of excess mortality linked to weight, like Julie Gerberding of the CDC's famous discredited estimate of mortality due to overweight, were pulled from thin air.

Does this mean you should rush out and gain weight? Of course not. Does it mean that carrying an extra 100 lbs is good for you? Again, of course not. The health benefits of weight drop off significantly at a BMI of 35--204 lbs for a 5' 4" woman and 244 for a 5' 10" man.

In addition, the BMI as an index to health has to be taken with a grain of salt, because it completely the two Bs: boobs and brawn. I'm carrying 6 lbs of boob, which do not go away even if I weigh 108 (I've tried it.) That raises my BMI by 1.1. Does this mean I'm much less healthy than a completely flat chested woman of my size? I doubt it.

In a similar manner, when my son was playing on his college football team, he had a BMI well into the "obese" range, based on his height and weight, though he was measured as having a body fat percentage of 17% which is normal for a male. This discrepancy was because he was carrying an enormous muscle mass which the BMI calculations treat as if they were body fat.

One of the things doctors always tell people with diabetes is that if they could lose as little as ten pounds, they could lose the diabetes. Hundreds if not thousands of you reading this blog have probably tried this and found it to be nonsense. Some of us, like, say, me, have lost over 15% of our body weight and found it to have zero impact on our blood sugars.

Well, heave a sigh of relief. Your weight is not going to kill you. Then take another deep breath because no matter WHAT you weigh, your blood sugars might: the connection between blood sugars rising over 140 mg/dl after each meal and heart attack is very well documented with more research confirming it every year.

So concentrate on getting those blood sugars down. Get your A1c as close to 5% as you can, and once you do look forward to having long debates about "healthy eating" with your grandkids and great grandkids!

More Problems with Galvus the Other DPP-4 Inhibitor

UPDATE (April 2, 2013): Before you take Byetta, Victoza, Onglyza, or Januvia please read about the new research that shows that they, and probably all incretin drugs, cause severely abnormal cell growth in the pancreas and precancerous tumors. You'll find that information HERE.

Original Post:

There's a new and troubling problem connected with DPP-4 inhibition. Read about it here:

New Safety Warning Delays Norvartis Diabetes Drug

Galvus is the other drug that uses the same mechanism to lower blood sugars as Januvia does. It is a DPP-4 inhibitor which has been approved for use in Europe and Latin America, but so far, not in the U.S.. It came up for approval around the same time as Januvia, but the FDA refused to approve it citing vaguely described "skin-related findings."

The chances are very good that these skin related findings are the same ones that have recently been discovered to occur with Januvia, including the potentially fatal Stevens-Johnson syndrome, where your skin separates from your body, as well as other allergic skin reactions including severe rashes and swelling.

There's no mystery why Januvia and Galvus cause such problems. Both suppress DPP-4 which, besides having a role in eliminating GLP-1 from the body, are major players in the regulation of the immune system. Stop DPP-4 from doing its job, and the immune system will start displaying subtle changes like rises in some white blood cells and not so subtle changes, like major allergic skin reactions.

The recent discovery of these Januvia side effects is detailed in this Reuters news story:
(Merk's Januvia Wins New Uses but Risks Outlined.).

Now a new problem has emerged with Galvus. When prescribed in the dose needed to make it a once a day pill, like Januvia, it can elevate liver enzymes to an unacceptable level. Elevated liver enzymes tell you that liver cells are being damaged or killed. Kill enough of them and you are looking at a liver transplant or death.

It was high liver enzymes that first warned of the toxicity of an earlier diabetes drug, Rezulin. Unfortunately few doctors paid any attention to the warnings about elevated liver enzymes with Rezulin. So for several hundred patients on Rezulin, by the time they learned they had elevated liver enzymes it was too late and they died, several hundred of them.

The solution that Novartis has come up with to pretty up Galvus is to cut the recommended dose in half. Supposedly at the lower dose, taken twice a day, the liver enzymes signal disappears in the study pool. However, this does NOT mean that the drug isn't causing liver damage. Only that it may take longer for the tiny bits of damage to accumulate.

Galvus is a different molecule than Januvia, but we don't know whether the damage was caused by something specific to the Galvus molecule or by fiddling around with DPP-4 and GLP-1. There is no requirement for drug companies to study and explain WHY a certain dangeous side effect occurs with their drug.

Since the two drugs appear to be pretty similar in their effect on the body. It would probably be a very good idea to get your liver enzymes checked every year if you are taking Januvia and if you see any sign that your liver enzymes are rising, get off the drug.

If your doctor pooh-poohs your concern, remember that busy doctors are very unlikely to know about newly discovered side effects. Your doctor probably also doesn't know about the immune system and skin problems that FDA just discovered with Januvia and added to the prescribing information. The drug company reps who give doctors 99% of their "education" about new drugs are not legally required to inform doctors about new warnings put into the Prescribing Information doctors rarely read.

Debugging Unexpected Blood Sugar Highs

Every time I get things working, as far as balancing food and insulin, something changes and I get knocked back to square one. And, surprise, surprise, it has happened again.

Out of the blue, last week, I started seeing highs after meals using doses of insulin that up until then had matched specific food inputs perfectly. Over the week they've gotten worse until yesterday I spent most of the day well over 150 mg/dl and partly over 200, though I used more insulin yesterday than I've ever before used in one day.

I checked the Usual Suspects that I always consider when my blood sugar goes blooey on insulin, which I'll list here:

1. Meter problem: I tested highs on two different meters with strips from two batches and they matched within 4 mg/dl. No meter problem. (Of course, I washed my hands after seeing the first high, to make sure I didn't have sugary fingers.)

2. Insulin problem: Because I use very small doses of insulin, one vial or pen can last me a very long time. But over the past two years I've learned that any vial of insulin that gets used 3 times a day can deteriorate after six weeks, even if I've only used 100 units out of the 300 in the bottle. Sometimes I can see tiny crystals in the previously clear insulin. Sometimes I can't see anything, but replacing the vial or pen solves the problem of mysterious highs.

I replaced both my R and my Novolog pen with new ones. The problem did not go away.

3. Getting Sick? Sometimes we see rises in blood sugar days before we get sick.

I did end up developing a nasty viral outbreak in my mouth this past week, which is something I get from time to time. But I'm not sure that would be enough to cause the dramatic deterioration I'm seeing. I've had it before without seeing highs. And the outbreak is clearing up while the blood sugars are getting worse.

4. Carb Creep/Wrong Carb Insulin Ratio: Is that 30 grams of carbs really 60? Sometimes we get sloppy with our carb counting.

I thought that might be the problem, but yesterday I weighed portions and had a very good idea of what I was eating and saw crazy high numbers. More importantly, the timing of the highs was really strange--with the highest reading almost 3 hours after eating and injecting Novolog. When I did a Novolog correction at 3 hours, I ended up with a wicked low an hour later. This is NOT the usual pattern I see at all, but it does require further investigation.

5. A Change in Meds or Supplements: Any medication or supplement we take, whether for diabetes or not, can impact on our blood sugar.

In this case there were two obvious suspects. The high blood sugars started before I stopped taking Metformin again, and ideally I should have NOT stopped taking metformin when I developed highs, because my blood sugar will go up a bit without metformin, though not a lot. But I had no choice, as the Metformin was giving me continual burning stomach pain and I was also feeling very exhausted after taking it, which is something that had gone away when I stopped taking it before. So I decided that I had to stop taking it, because it was clearly not helping me out anymore.

But that said, I had stopped taking Metformin for several months only a few months ago without seeing dramatic highs. Usually I see a rise of about 10 mg/dl in fasting blood sugar and maybe of 20 mg/dl after eating when I am not taking Metformin. In the past, to correct for this I had only had to add another unit or so to my dose at meals, and 1.5 unit of NPH at night to knock down the fasting blood sugar. This was nothing like the 50-70 mg/dl rise I have been seeing this past week.

A I blogged earlier, I have also recently started taking 1000 IU of Vitamin E, which initially was causing lows which stopped after a week or so. Then after reading up about Vitamin E I added 2 Calcium/Magnesium supplement pills to my daily regimen, since it turns out that without available Cal/Mag Vitamin D may store metals in your bones. Hmmmmm. Needs further investigation!

6. Too Much Insulin Causing IR? It's one of the ironies of insulin use that if you use too much insulin the body may get into a counter-regulatory mode where surges fight and flight hormones push blood sugar up out of the low range and the body becomes more insulin resistant out of self-protection. I have always had a huge problem with unwanted counter-regulation in the past, which is characteristic of MODY-2, the kind of genetic diabetes I'm currently being tested for.

So this idea isn't so far fetched. When I figured out the right dose of Lantus to use to avoid hypos last year, I saw very high post-prandial numbers--and that was why I stopped the Lantus. I have been using increasing doses of NPH for the past month to try to get my always high fasting bg down and had added a unit or two every morning, too. Requires investigation.

7. Deteriorating Beta Cells: While this is not a likely explanation, we can't rule out that something may have caused my beta cells to shut down or otherwise misbehave. I don't think this is likely, because the last time I stopped using insulin (with a very low carb diet) my post-prandial control was a lot better than it had been 2 years ago when I started insulin, suggesting that beta cell rest had given me more function in my beta cells, not less.

Into Debugging Mode!

Since I come from a computer engineering background, I'm familiar with the techniques used to debug problems that develop in large, complex, poorly documented systems. So now it's time to sort out what might be causing these highs.

Key to doing this is the basic debugging concept: When there are multiple possible causes for a poorly understood problem, go back to something that works (if possible) and then change one thing at a time and see if you can reproduce the problem. Start with the most likely and work back to the least likely.

So here's what I'm gong to do:

1. Cut out everything that looks like it might be causing the problem: the Vitamin E/Cal/Mag supplementation, carbs, and NPH. I can do this because I am fortunate to still have some natural insulin production left. A Type 1 could not cut out a basal insulin, because cutting out the basal could make them very, very sick.

2. Cut carbs way, way down and stick to foods where I'm certain about the carb count. My most recent stint of low carbing wasn't that long ago. I was able to stay between 95-120 most of the time if I kept my carbs under 12 grams per meal and 6 at breakfast, a la Bernstein diabetes diet. I have some other problems that this diet makes worse, but for now I'm going to eat that way to get to an acceptable baseline. It mostly eliminates the problems caused by mismatching insulin to meals.

3. Add back one suspicious element at a time to see if I can determine what is causing the problem. Here's my thinking:

a. Add nighttime NPH. I started using NPH at night when I was off Metformin before because without Metformin my fasting blood sugar is always around 100 or more. It did not seem to cause a rise in my day time blood sugars. Because my fasting bg on a Bernstein diet will quickly go up to 110-120 mg/dl I want to address the high fasting value first before doing anything else.

If after doing this I don't see daytime highs:

b. Raise the number of carbs I eat in each meal gradually using my old reliable R insulin and my usual Non-Met carb/insulin ratio (1:10-1:12). Use measured portions of foods I'm familiar with. This should quickly tell me if using the wrong carb/insulin ratio was the problem.

If this solves the problem of daytime highs:

c. Add back the Vitamin D and Calcium/Magnesium.

If this doesn't cause daytime highs:

d. Add back the morning NPH dose.

Obviously, if one of these elements DOES cause the daytime highs, I'll have to stop using it.

I should wait a couple days before introducing each element.

Obviously, this is all a pain in the neck, but when I'm done, I should have a better idea of what is going on. I hope! If the problem was that I'm really about to come down with a cold, I might add everything back in and not reproduce the problem, but that works too.

Any other debugging suggestions from you folks who live with this crap day in and day out?

Good Germs, Bad Germs

No, this is not a pun on the title of Gary Taubes' new book. It's the name of a completely different book which should be of great interest to anyone whose diabetes is autoimmune in origin.

Good Germs, Bad Germs: Health and Survival in a Bacterial World by Jessica Snyder Sachs, is an up-to-date summary of what we know about how bacteria interact with humans.

It's a fascinating story, because after a lifetime of "fighting germs" it seems that scientists are coming to learn that the interaction between bacteria and our bodies is far more complex than was ever realized and we have to work with germs and make alliances with "good germs" in order to survive.

Why this relates to diabetes is that the book starts out with several chapters that explore in greater detail than I've seen elsewhere, the research that has been establishing "The Hygiene Hypothesis." This is the idea that the huge rise in autoimmune disease we are currently experiencing is being caused by too much cleanliness.

It is starting to look like we are not being exposed to enough of the right bacteria very early in life or as we go through our daily lives, thanks to changes in water treatment, how we get our food, how we medicate illness, and how we clean our homes.

It turns out that our bodies are complex ecosystems in which maintaining populations of billions of bacteria of various kinds is essential for preserving our health, particularly in the digestive system, where, if our population of bacteria are killed off, the digestive system fails to function properly. Children absorb the good bacteria they need to have populating their own digestive tract from birth on. A caesarian birth, for example, results in a baby who is not exposed to the bacteria found in the mother's perineal area, which raises the risk of developing autoimmune problems like asthma and Type 1 diabetes.

Children who are given antibiotics early in life which kill off the developing populations of healthful bacteria also develop more autoimmune diseases, particularly asthma.

And all of us who drink filtered water (which the book mentions was not common until the last 25 years of the 20th century) and eat packaged, preservative-filled foods, may not be maintaining the colonies of soil and fecal bacteria which our bodies depend on to regulate our immune systems and fend off dangerous bacterial invaders.

An important point that Sach's raises in Good Germs, Bad Germs, is that while in the past many people, including those opposed to vaccination, have argued that exposure to disease is required for the development of a healthy immune systems this is not, in fact, true. More recent research suggests that it is not infection with disease that protects children. Disease, is NOT good for people.

What is good for people is acquiring populations of benign non-disease causing bacteria that live on skin, on mucous membranes, and within the digestive tract. This is because these populations of benign bacteria do two things. One is that they fill up the ecological niche your body represents, making no room for the more dangerous bacteria which cause disease to move in.

The other, which is just starting to be understood, is that by their very presence, these benign bacteria send out biochemical signals that cause the immune system to respond by developing what is called "tolerance"--i.e. turning down the immune system. It is this tolerance that turns off the inappropriate immune attacks that cause asthma, diabetes, multiple sclerosis, etc. When the body is not populated by the bacteria it expects to meet, it does not develop tolerance, and instead seems to go on high alert, and unfortunately, this leads it to attack things like peanuts and pancreases.

Another interesting finding is that having the right bacteria established in your body causes changes in the cytokine mix which affect your mood. Sachs describes some research that finds that when levels of Interleukin-10, a cytokine that is secreted when tolerance develops, rise, serotonin levels surge too. The implication here is that the depression that is associated with autoimmune disease may not be psychological. Yes, it is a bummer having to deal with diabetes, but it may FEEL like a bummer because of the lack of calming chemicals in the brain.

This reminded me of one of the oddities of tuberculosis in the 19th century, which is that its victims were always described as being bizarrely cheerful especially as their condition worsened. One wonders if perhaps this had something to do with their immune systems having developed too much tolerance and pumping out serotonin happy juice. The book mentions that this kind of inappropriate tolerance can develop in the presence of some kinds of chronic infections that the immune system cannot take care of.

The good news reported in this book is that there are people working on using carefully cultured populations of benign bacteria to modulate the immune system. The bad news is that it turns out that bacteria can trade just about any trait you can think of with each other, particularly resistance to any antibiotic ever made, and they do it across species lines and very, very fast. A bad bug you pick up on your spinach can pick up a drug resistance gene from a "good" bacteria in your gut in the 3 hours it takes to hit your lower intestine.

This means that the most "healthful" bacteria in the world can go bad if you already have drug resistant bacteria haunting your gut. And unfortunately, most of us do. Much of the rest of the book is taken up with discussing the problems caused by the drug resistant bacteria that now fill our world.

One huge reason for the unstoppable growth of MRSA and other bacteria that do not respond to antibiotics is the overuse of antibiotics in animal feed. It turns out that the problem is not just residues that you might eat. The problem is that resistance genes that develop in livestock pass into the ground and get out into the world where the promiscuous bacteria trade them around continually. You don't need to eat meat to get bacteria in your gut that are resistant to antibiotics used only in cattle.

Another problem is the use of antibacterial soaps which kill off the friendly bacteria in our homes and leave a nice, big empty place for baddies to grow. Sachs compares cleaning your cutting board with antibiotic soap to nuking your lawn with Roundup without reseeding it, which ensures that you will end up ONLY with clumps of crabgrass and weeds.

There's lots more in this book that you should read if you are concerned about MRSA or worry about infection--a huge issue for anyone whose diabetes is not in excellent control.

For those of you who won't get around to reading it, here are a few "takeaway messages."

1. If you are serious about preventing autoimmune disease don't overprotect your baby from dirt. Throw out the antibacterial soaps. Let your kids get dirty. Let them play with the dog. Let them help diaper the baby. Eat fresh vegetables from local farms where possible.

2. Do not give your children antibiotics for viral diseases. If you do need an antibiotic, try to get the doctor to do a culture first so that the doctor prescribes a drug that is limited to attacking the kind of infection you have, rather than the "broad spectrum" antibiotics that also wipe out the bugs that are teaching your kids' immune system how to play nice.

3. Some autoimmune disease is caused by genetic flaws in the mechanisms that the body uses to develop tolerance. If that is the case, no amount of exposure to healthful bacteria will help. This may be what is going on in families that have long histories of autoimmune disease going back generations.

4. MRSA (antibiotic resistant staph) is probably the biggest health risk we all face. It is a direct result of the overuse of antibiotics in both hospitals and in animal feed. There is no easy solution to this problem. It is a huge killer of people who go to hospitals for other causes. It also produces a pneumonia that can be fatal very quickly, often in young people. Unfortunately, the U.S., alone in the Western World has no organized system for tracking hospital borne infections. So you will not know when there is an epidemic of MRSA in your local hospital. In fact, doctors at the hospital across town may not know about it.

5. If you have diabetes, the best thing you can do is avoid getting infections by keeping your blood sugar normal. People with diabetes who have high blood sugars are more prone to drug resistant infections than the rest of the population. These infections are a huge cause of amputation. Because drug resistant infections once established can be impossible to fight, take any infection no matter how small very seriously. If you are a diabetic with an A1c over 6.5% and your doctor does not treat a foot infection as an emergency, find another doctor who will.
