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):

This is hillarious (and oh yes, I was right, breakfast cereals, bread, low fat etc., super "healthy"!):

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.
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 ...
