how tall are u? u may not even be over weight, just "bigger". but if you r sure you are then try to fill your house with alot of fruit and veggies and healthy food. try not to have any sweets. that way u eat what is in your house. and excersize some. and chew gum if u have cravings. gum is really great....too bad i can't have any wit my braces.:( oh well good luck!
