There are a lot of MMA guys who do Paleo too. I think Forest Griffin does Paleo and I know he has a quote in Robb Wolf's Paleo Solution. And sure there are some on the other side of the fence. Randy Couture not only was a vegetarian but I believe he might have even been Vegan and he was the champ for awhile. Thing with these guys are they are professional athletes who work out really intensely as their day job. So they end up burning off a lot of those carbs that they consume. Just like you hear Michael Phelps and Lance Armstrong consuming massive amounts of pasta when they are training heavy. But long term all that is just crying out "inflammation".

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
