I lost 25 lbs just from the liquid diet for preop and postop, and I was concerned about gaining that back since I'm now on solids, but I was told not to worry about that right now, just count my calories(900-1000) a day, and that when I get my first fill on 3/12, that I will start loosing my weight from the band...don't know if this helps, but its what I've been told....Good Luck....
