Everybody does loses at a different rate. I had my surgery Jan 8 and lost 40lbs by March. It is now July and I am at the same 40lbs. At first I was discouraged and then I realized at least I am not gaining. What I can tell you is exercise can make the difference. My nutritionist made one big suggestion and although you may feel like you can not exercise much, weights, even light ones are great. Stop comparing yourself and keep trying your hardest.
