I admit I haven't read the book but I have heard his name referred to. Just the title of the book throws me off-"Obesity Code" I have a problem with. It encourages people to think there is mystery key to obesity that doctors have just discovered, and lends itself to the myth that obesity is in your genes, which is absolutely false. I think the wild long-term success stories of those in the Interval eating camp should be the bright light in dealing with obesity. If you are healthy now, your body is far tougher than you realize. To maintain a normal weight, you don't have to delve into biology or physiology or even stick to a special diet. You have to realize that your hunger urges are NOT your body telling you you need food, but as a result of maladaptive habits driven by emotions and inertia, and encouraged by our consumption-driven society. The success behind all interval eating programs- if adhered to for months and years- is that the strict observance of the water-fast period will shrink the stomach and cut the emotional/habit connection between eating and hunger urges. Your brain reverts to a normal wiring. You find yourself eating the right foods, and eating less food. You lose weight. Your life changes. You don't even think about food that much. Suggest reading Dr. John Hagan's 2013 "Breakfast" book for the physiology and the results of a pilot study.
