Interesting show on the physiology of the obese
on the natgeo channel tonight called the "Science of Obesity". Basis is a simple formula-consume more calories than you expend, you gain weight. It also says an obese man at 40 has only consumed 25 calories more daily? throughout the years than a normal weight person. Also discusses how rapid weight loss increases hormones that increase hunger to return the body to its setpoint in weight and this is a big factor why weight loss can't be maintained easily.
