Certain medications--risperdal, zyprexa, depakote, lithium, and I believe even seroquel--cause hunger that you wouldn't believe. On BiPolar (BP) medications, my son went from 75 pounds to 150 lbs. in three years. He has been off medications now for three years and is still overweight, however he still only weighs 150 lbs. and has cut out the overeating. I take Paxil so I know the unrelenting hunger these medications can cause and kids are often just too young to fight the constant urge to eat. Heck, I blew up like a balloon myself until I cut out all sugar and junk food and lost the weight, but it's hard for even an adult to fight those horrible cravings. Before medications, I was always very thin, even with bipolar. I agree about the homework. He is probably unable to handle the homework bit right now.
