Thanks Vic, yeah he won’t eat steak at all but will eat very little of the others!
I'm going to be switching to one of these two

For other food, stick to eggs, burgers, steaks, fish and chicken. Pocket steak is a thing.
On the running thing, I haven't been running as of late, but that burns a ton of calories in the near term, and drops water weight from sweat. If he hasn't yet done so I'd suggest hill runs and fartleks over steady state flat runs.

Maybe try getting him to add protein to every meal. Just adding 3-4oz. of meat to every meal can really help. I found adding bacon and avocado to almost everything helped a little too well when I had trouble keeping weight on when I was younger.
