Weight loss

I have not lost any weight for about 6 months. I am pretty stable at the weight I am now. I had a tummy tuck 1 month ago. I still want to lose 10 pounds. Does anyone have an idea how to jump start this weight loss again? I am not cleared to exercise yet. It will be 2 more weeks. I exercised pretty constistantly before the tummy tuck, but this 10 pounds stayed. I have came to the conclusion that my body wants to be at this weight-however- I want to go lower. Another thing is that a friend of mine who had the surgery in Dec 03 has caught to me and I am so jealous because she will pass me up if I do not do something. I am so competive about this- I know I should not be. So - anyone have any ideas on how to lose this last 10 pound that is just hanging around? Any suggestions would be great. Thanks
