Janssen, 38, claims that he has eaten pizza for nearly every meal over the past 25 years. He said he rarely eats breakfast, subsisting on mainly coffee in the morning, and then downs a whole pizza for lunch and another one for dinner, day after day.
He does not drink or smoke, and exercises regularly by riding his bike long distances.
"I understand that this is a disgusting diet,'' he said. "You expect me to be overweight and have no energy, high blood pressure, and high cholesterol. Whenever I see a new doctor, I tell him, 'I have a terrible diet, and I only eat pizza.' With three different doctors, they have done bloodwork and my cholesterol levels and blood pressure are great, and I am fit and energetic.
"I'm sure when I'm 60 I'll drop dead of a heart attack, but right now I am fine."
