Diabetes - low caloric diet and exercise did nothing for heart!

A new report from an 11 years long just cancelled study "Look AHEAD", conducted by Dr. David Nathan (principal investigator) is going to be published.

Five thousand diabetes type 2 patients split in two groups, one (treatment group) underwent a rigorous diet (1200-1800kcal - about one half of general average!) and about three hours a week of exercise regimen, the other (control group) were only offered some general health information.

Results: in spite of 5% weight reduction in the treatment group - no difference in cardiovascular death!

See a write-up in NYT:

"Diabetes Study Ends Early With a Surprising Result" by Gina Kolata, October 19, 2012

The study randomly assigned 5,145 overweight or obese people with Type 2 diabetes to either a rigorous diet and exercise regimen or to sessions in which they got general health information. The diet involved 1,200 to 1,500 calories a day for those weighing less than 250 pounds and 1,500 to 1,800 calories a day for those weighing more. The exercise program was at least 175 minutes a week of moderate exercise.

But 11 years after the study began, researchers concluded it was futile to continue — the two groups had nearly identical rates of heart attacks, strokes and cardiovascular deaths.

My take on it?

I find it absolutely pathetic but also surprising! Only 5% weight reduction! Same rate of heart disease and stroke after after 11 years of consuming about half the calories of average American adult?!  How is that possible, unless...

     - half of the calories they threw out were in things like animal and dairy fat, fish, yolks and meat, leaving mostly carbs. Carbs - like perhaps those on the picture?

More, here are study materials and guidelines for this study ("Look AHEAD" trial):

Quote from the chapter demolishing the low carb diets:
The Claim [of low carb diets]
You’ll lose weight on the diets because they are low in carbohydrate.

The Truth
You may lose weight on the diets because they contain fewer total calories than most people consume. Most of the diets range from 1000-1800 calories. Also, many cause ketosis. In ketosis, the body breaks down fat stores, producing toxic wastes called ketones. To flush out the ketones, the kidneys pull water from the body. It’s the loss of water, not fat, that results in quick weight loss.

I can't help it, it so so so scientific, it is cracking me up! I need some vegan comments to straighten me up, please please ...

This is a "Surprising Result" mainly for those following a wrong paradigm.

Oh, well, what a sad state of affairs in the medical sciences.

1200-1500 calories a day with exercise in obese folk and only a 5% weight reduction. Please. Basically the same group as the "general health information" group.

Yup. Absolutely pathethic! I am looking forward to find out, when they publish, what exactly were they eating? American Diabetes Assoc guidelines?

Hey, you inspired me! I hope you will take a look at my related blog post.

I'll take my toxic ketones bodies, thanks. My brain, muscles and heart appreciate them very much.

Wow, I can't believe it was actually written as 'toxic'. No matter what the body has ketones even in high carb diets (at least in healthy individuals). The hilarity/absurdity is astounding.

Fix your blog commenting thing. You get so many spam.

I had to unsubscribe from comments b/c of the spam emails I got from your spam commenters.

I have to type in a password but yet you still get spammers? :/

Sorry, I allowed "anonymous" because some people could not post. Some spammers are members of google bloggers so disallowing anonymous would not exclude them. Is there a better way? If I make it too much hassle then it would discourage legitimate comments.
