My stepdaughter is constantly hungry - she can eat a meal (usually consisting of a meat, vegetable and rice or potato, all cooked healthily because I'm on weight watchers), and an hour later, she says she's hungry again. There are times I've seen her eat more than a grown man. Her pediatrician says she's overweight by about 15 pounds, and I've noticed an increase in weight as well. She's active, likes to swim and be outside running around and riding bikes.
