hi all you really need to do is eat less, exercise at east twice a day. don't go out and buy like pills or anything b/c for kids our age it could make us sick and prob. wouldn't work. my sister is on slim fast and it's really helping her so like save mone or convince ur parents to help you and go out and buy some slim fast. it shouldn't be too much but their diff. prices everywhere. i hope i helped!! good luck :-)
