I tried to look up "set point" in the Obesity Handbook by Bray and Bouchard. On pg 168 Vol one:
"Whatever the mechanisms in many obesity-prone individuals, there is a constant upward resetting of the defended body weight in the face of continued excess caloric intake such that whatever level of adiposity an individual reaches when caloric restriction is instituted, there is a powerful drive to regain that level when caloric restriction is lifted."
