I was just wondering if someone could think of something else. I have thought of diet, but he eats well.
I would say it's medical. Maybe candida or thyroid problems which can cause extreme fatigue.

Regardless, millions of people have great, healthy diets, they still get sick.
Take candida for example. Overdose on fresh fruit (sugar), you will get candida. Cruciferous vegetables can cause thyroid troubles.
