I guess, Todd, the best advice that I can give you is to start working on it now. You're only 13, so it will be easier, however, I am not guaranteeing anything. I think that you should definitely cut back on what you eat, work out more (but start off slowly for your safety), and drink lots of water. You may want to ask your doctor what would be the safest way around this. All I can say is the best of luck to you, and I hope it all works out for you. :)
