Hi my 16 year old son is an extremely picky eater he basically only eats chips, crisps and other junk food I've tried for years to get him to eat anything else but he refuses and is willing to starve himself over eating food he doesn't like however he doesn't have any friends so never really goes out to get excersize this along with his bad diet has resulted in him becoming obese he is nearly 17 stone and I'm at my wits end I don't know what to do.
