Well said. I believe you are right. That and ignorance of how Leptin works, setpoint or lipostat theory of bodyweight regulation...once you've gotten fat, your setpoint goes up and the hunger signals are far greater than folks who have never gotten fat. You can have 2 athletes with identical weight height and BF%, but if one had been fat once, their hunger signals from the brain will be far greater than the athlete who was always slim.
