Our Imaginary Weight Problem
http://www.nytimes.com/2013/01/03/opinion/our-imaginary-weight-problem.html?_r=2But a new meta-analysis of the relationship between weight and mortality risk, involving nearly three million subjects from more than a dozen countries, illustrates just how exaggerated and unscientific that claim is.
The meta-analysis, published this week in The Journal of the American Medical Association, reviewed data from nearly a hundred large epidemiological studies to determine the correlation between body mass and mortality risk. The results ought to stun anyone who assumes the definition of normal or healthy weight used by our public health authorities is actually supported by the medical literature.
The study, by Katherine M. Flegal and her associates at the C.D.C. and the National Institutes of Health, found that all adults categorized as overweight and most of those categorized as obese have a lower mortality risk than so-called normal-weight individuals. If the government were to redefine normal weight as one that doesnt increase the risk of death, then about 130 million of the 165 million American adults currently categorized as overweight and obese would be re-categorized as normal weight instead.

(970 posts)...and a lot of these kids are fucking OBESE! When I was a kid in the 60s-70s, we usually had the "fat kid" (singular) in each class. Of course, back then we didn't have the glut of fast food and 900 oz sodas we have now. I did plenty of sitting on my ass as a kid staying in my room reading and listening to music, but I still had time to ride my bike and get some exercise.
