I heard him say in the interview that he tries to eat "nonrefined" foods and starting at 22:05 (

He said that he avoids gluten and trains on a much lower carb diet than what most people suggest. When it's racing season, he apparently increases his carb intake. He's a fan of Primal/Paleo dieter and former ironman triathlete Mark Sisson. It sounds like he's eating much less refined and processed foods than the SAD. In addition to the diet he describes being mostly "Paleo," aside from the quinoa and small amount of yogurt, the raw meat aspect means that if what he reports is accurate, that his diet comes close to a raw Paleo diet. Given that many people here don't eat 100% raw Paleo, it sounds like he would actually fit in relatively well here.
