I have a 16 year old son in the 11th grade. He wakes up and drinks a little soda and skips lunch and doesn't get home until about 4:15p.m. He usually eats a broiled hamburger patty, or a slice of pizza, or some type of chicken for supper and that's all. I can't get him to eat anything healthy. He is a very picky eater. I keep telling him he needs to take care of himself. Any suggestions?
