I eat nothing that's processed or refined - no high-fructose corn syrup, no sugar, no trans-fats. I eat a lot of fish and monounsaturated fats from olives, olive oil and nuts. A lot of organic, fresh fruits and vegetables. No bread. No gluten. No wheat. No rice.

When I ran across America, for 75 days I ate 10,000 calories a day. I still lost about five pounds.

Running is a simple, primitive act, and therein lays its power. For it is one of the few commonalities left between us as a human race.

I have an ElliptiGO. It's a standup bicycle. You don't pedal; you stride on it. It allows me to have the same striding motion as running without the impact.

I've raced on all seven continents at least twice. I've probably run thousands of races. But the single race that I'm most proud is a 10K. Yes, a 10K. I ran it with my daughter on her 10th birthday.

Sure I'm cut but not for the sake of vanity.
