You have had some good advice here. There is no way you will be able to eat the way we did before surgery. Those days are over. The great thing about the lap band is that it does help me eat less. I need to make smart choices about what I put in my mouth. I never eat pizza, Pasta, bread potatoes or rice. I do eat lots of vegetables, fruit and healthy protein( fish, chicken etc), I drink a ton of Water, but NEVER with meals. I will not drink anything other than water or clear tea. I exercise 7 to 9 times a week very vigorously and all of this helps the weight come off slowly but surely. I have lost 60 lbs and was banded August 8. I know this sounds rough but it is not so bad, really. I have come to really value well cooked fresh food. I feel so much better after I exercise. Yes, it is hard to get out there, but I found an exercise buddy and we encourage each other, plus it is a bit social, so the time passes much faster.
Good luck! It sounds like you may need a bit of a shift in your thinking around food and exercise, but you must already be feeling so much better than before! I know you can do it!
