6. Have him see a doctor. Work from the inside out, body work, then help with his stressors.

The body and the mind are not separate. In my experience a thorough, sympathetic, wholistic approach without judgment and with sympathy for what might be his own internal judgment gives the best potential for dealing with whatever is going on. If he is eating candy in order to feel better, he might respond to having a good, non-reactive source of snacks. Beef jerky, fruit, a little cheese, popcorn, hummus and chips...they're not perfect and have carbs but adding protein and fiber will slow down the blood sugar swings. But I think it's a combination of things and he can feel better just knowing you care and respect him and are interested in helping, and so are others.
