Dan, a 38-old-year old woodworker from Maryland claims he has only eaten pizza for the last 25 years. Cheese pizza. Exclusively. He hasn't stop despite being diagnosed with diabetes. Then doctors told him to change otherwise he'd lose his life or limbs.

According to his interview in Vice, he has been eating an entire 14-inch cheese pizza every day and he never gets sick of it. "If I go to one pizza shop or another brand," he says, "it's like eating a completely different meal."
When I first got diabetes, my endocrinologist said, "You should go to a nutritionist. You eat horribly." So I went to a nutritionist, and it was a waste of time. They just basically give you a list of things to try, saying, "Oh, you're a vegetarian; you should try this, this, and this." And of course I'm not going to try any of those. I like pizza. I've never gotten a negative reaction except from my first endocrinologist. But all the other doctors have said, "Your cholesterol is fine. You seem healthy. Keep doing what you're doing." I haven't had anyone truly concerned about it, except for my fiancée, and she's not overly concerned. With her advice and support, I've been seeing a therapist about my food aversion, and we've been exploring why I have such a limited diet. I must say, even though I sound like a horribly unhealthy and fat person, I'm not. I'm thin. I have tons of energy, and I feel great every day, so there might be something to the exclusive pizza diet.
Do you think Dan is telling the truth?
