Johnny is an actor, but hadn’t had much luck in landing any gigs. He started eating healthy and exercising to cope with the stress. He was offered the lead in a play shortly afterwards, and he knew it was because of his new physique. He currently runs 5 miles every morning and goes to the gym for 4 hours in the evening. He eats an apple a day to keep the doctor away and a small salad (which he forcibly throws up after he eats it). What diagnosis would you give Johnny and why?
