"We create a strict daily diet. They have a whole food-based diet that's very, very natural: regular meats, fresh fruits, nuts and seeds, veggies. These aren't processed foods. That's because it's mainly the quality of food that's how they're getting their nutrients.

What we know is that you can get the same nutrition from convenience foods, but it won't be of the same quality. The quality of the protein you get from chicken breast is just higher than what you'll get from a powder. Their bodies are their jobs, so how they feel really determines how well they'll succeed.

Going to food first is not only possible. It's a good idea. The highest achieving athlete, who is training eight hours a day, 95 percent of his diet is whole and real foods. You don't have to lean on potions or pills. Food is the best source of nutrients. It's not as sexy as some new seed from the Amazon, but 99 percent of the time, people get their nutritional material from food. You might need to supplement, but if these athletes can do with food, so can you."
