Matt Lalonde on the science behind the Paleo Diet

Wow, Matt Lalonde's story is much like mine: Vegetarian for a decade, discovered CrossFit, wary of Paleo so did Zone Diet instead, and eventually transitioned to Paleo and omnivorousness. What I like most about Lalonde is his claim that it's too simplistic to say "eat like a caveman." There has to be science to back up dietary claims. Also, his discussion of genetic vs. epigenetic factors.
