ok, so if u hav a treadmill or can go walking regularly start doing that! go for about 20/30 mins per day (even 10 if u cant do more) and it will help. avoid being around foods that make u gain weight and try to find foods that arent so fatty that u like. start exercising regularly and find something fun that takes energy that u can do!

don't over eat, try not to binge. Your only 15, as your body develops your metabolism and structure will change.

Pretty much, I'm saying using weight loss techniques can help, but don't overdo it.

Eat three well balanced (referring to nutritional value, not the plate on the table) meals a day and exercise regularly. Running, jogging, biking are some good ones and they are even more enjoyable with a friend or two.
