Hey Jpye! In my own experience, it did get easier to resist the foods I shouldn't be eating. Those junk cravings did lessen. I got hungry sometimes, but that's to be expected. I learned how to plan!
What someone said once here on a thread was that the stomach doesn't shrink--but it does get used to having less food to feel full. As I remember, the "full receptors" get overridden if someone eats large quantities of food at meals over an extended period, but if they go back to more normal eating, the full receptors readjust. I don't know whether it's true...
Either way, it's good news!
