"to go TRUE Paleo, you'd have to pick a sport other than triathlon - such as farming, or hunting lions."
You're right about that. You would also need a time machine. And erase all memories of your former life. And go hungry most of the time, probably starve most of your life. But that's not the point though. Paleo diet is a way to get clues about what kind of foods the human body is genetically adapted to and try to incorporate them in a modern life style. The thinking is that grains doesn't provide the body with the right kind of fuel whether you're an athlete or not. They contain anti nutrients that actually, on the contrary, will interfere with the body's ability to absorb nutrients like vitamins and minerals. Paleo diet doesn't claim to be natural, but rather to try to mimic the natural in the best way possible given any individuals needs and possibilities.
