Prior to banding I was insanely, physically hungry most of the time (stomach growling, getting shaky and lightheaded if I didn't eat, etc.). After surgery and upon getting to a good fill level, I am only sometimes mildly hungry at appropriate times (around typical meal times unless I'm PMSing! ), and am now full with smaller portions of food. The band definitely had an impact on my body's hunger, which allowed me to stop eating so much and lose weight. However, I never really had a terrible diet--my food choices in general were pretty good pre-band, I wasn't an emotional eater, it was just that I was so hungry that I ate A LOT. I can tell when I need a fill, because I start to get that driving, insanely hungry feeling again, which resolves after a slight fill. I feel so much better due to the weight loss, and am physically ABLE to be an avid runner now, when before I wasn't due to fatigue and foot/ankle/knee problems. I am a real believer of the vagus nerve theory! I think the band may work psychosomatically for some, but it definitely had a physical impact on me.
