I was banded in May and lost 24 lbs within the first few weeks. Since then I have had 3 fills and my band is at 5cc's. I go down a few pounds then back up a few, even with exercising 4-5 days a week. I am at a total of 32 lbs at 4 months post op and frustrated too that I am not losing more quickly.
I find that if I eat a bit more, I actually lose. So....I think sometimes your body goes into starvation mode when you eat too little. I have a hard time with eating Protein, seems to get stuck.
