It depends on what your diet is. If you exercise and eat vegitables regularly, you would lose for weight than people who lie around and eat potatoe chips. Hope this helps! - Oh and make friends with a surgeon
I'm not sure how much you can lose, probably at most 1 pound. A way is to eat better and working out. I you have any diet questions or fun work-outs you can post a message on my wall and I will...
First, ask your parents and your doctor whether you SHOULD be losing weight. If so, they should be able to provide you with a safe way in which to lose weight.
