What if obesity has nothing to do with overeating?

Peter Attia, MD, once judged patients who were overweight or obese until, despite exercising three or four hours a day and following the food pyramid to the letter, he gained a significant amount of weight and developed metabolic syndrome. As he explains in this recently posted TEDMED talk, the experience motivated him to radically change his diet, helped him lose 40 pounds, and greatly shifted his perspective on the conventional wisdom of nutrition. And he became almost maniacally obsessed in trying to understand the real relationship between obesity and insulin resistance.

Watch Attia's talk to find out how he's working with a team of researchers with competing hypotheses on the cause of the nation's obesity epidemic to understand how the various foods we consume affect our bodies - and how use this information can be used to help people make sustainable lifestyle changes.
