Zak’s been talking about doing a “40 Day Paleo Challenge” for a couple of weeks now and he’s invited all of his (Facebook) friends to join him.  He asked me to write up a brief guide to Paleo for anyone who wants to play along, and when I was putting it together I decided to extend the invite here to you too.  It’s not a contest or competition, just an opportunity to try the Paleo lifestyle for 40 days, to give it a fair shot and to see if it might make a difference for you.
