If you are 13 What is the fastest way to lose 20 pounds besides starving yourself?

well the best way is to eat a light meal plus healthy snacks every day. and you can go to a local gym or jog around the block. but again your body is still growing just give it time. good luck i hope you can lose the weight you want!! The faster you lose weight the more likely you are to gain it all back. If you want long-lasting weight loss you can only get that by making long-lasting changes in the way that you eat and view food. Go for healthy eating, the rest will take care of itself.
