Diet pills are not the answer and can be harmful, let alone a big waste of money! You may want to take a look at teens.sparkpeople.com/resource/nutrition_a rticles.asp?id=510 for more info. We do not recommend any diet pills for anyone. They do not teach you healthy habits and can be harmful to your health or do nothing at all for you. Please do not take them!
The best thing for you to do is make sure you are eating the proper nutrition along with doing exercise (cardio and strength training). Doing those things will help you achieve your goals and allow you maintain a healthy weight.
Think of it this way too: If diet pills or other "miracle" supplements really worked, everyone would be taking them and no one would be overweight. They don't work, so save your money.
