sorry, there is no magic pill to help you lose weight. moreoever, those pills that claim to melt fat off can be dangerous to your health.
i'd suggest eating a healthy diet that is high in fiber and full of fresh veggies and fruits. combine that with a good exercise program and you will most likely see results (if your weight issue is not caused by an underlying health condition). try to do some cardio (running, walking, eliptical machine, jump rope) for 20 or 30 minutes a day. do some weight training which will not only tone your body, but also build muscle which increases your metabolism.
