His name is Dan Janssen and for the last 25 years of his life he has eaten nothing but pizza! To top it off, he's fit, healthy, and engaged.

I’ve been eating pizza exclusively every day of my life for the past 25 years, and I’m not just talking about a slice of pizza every day. I usually eat an entire 14″ pizza, and I only eat cheese pizza. I never get sick of it. If I go to one pizza shop or another brand, it’s like eating a completely different meal.

Right around the age of 15 Dan made the decision to switch to his vegetarian, all pizza diet. But as a vegetarian, he hates vegetables so it's nothing but cheese pizza for him. He says his go-to frozen pizza is Red Baron, nah nah nah, it's Mama Bosso's all the way.
According to Consumer Reports the best frozen pizzas are:

  1. Home Run Inn
  2. Amy's
  3. Red Baron
  4. DiGiorno
