I think the goal is to not feel physical hunger. Once you do, youre just dealing with willpower and as we know lots of us lose that battle. Fills arent overrated to me, I think they're key. The reason lots of doctors schedule fills post op is that experience and research dictate that most people heal and are back to normal 4-6 weeks post op. If you aren't one of those people then you cancel the appointment and move it to when you feel you need it. I was told by my surgeon that you shouldnt be struggling too hard and fighting hunger too much...because then you could just be on a regular "diet". This is where the band comes in, when you have proper restriction you fight alot less with physical hunger therefore youre able to lose weight .
