Once I committed to LCHF and found hunger & cravings disappeared if I completely avoided sugar and all but a few carbs, I found that my cravings were indeed medical, not due to lack of willpower or a personal choice. Yes, having a bite and then more bites is a personal choice, but without cravings or hunger I rarely feel tempted and realize that this is how "normal" people feel most of the time - their BG, insulin resistance & hormones are not driving them to stuff themselves so they cannot imaging anyone "wanting" to do it.
