Great, your one of the few. Statistics are pretty clear that most people cannot willpower their way out of their food seeking behaviours. They are to a large extent not under your concious control.

correcting satiety signaling on a chemical level more directly addresses the problem in those folks.

yes, the food environment is the main problem, in a way, but only because it punishes having a certain set of chemical and lifestyle parameters and rewards others.
