I urge you to go check out Mark's Daily Apple if you haven't already - this resource was my #1 source of information on metabolism, exercise, and a more naturally-oriented lifestyle in general when I got started early last summer. I pored over Mark Sisson's site for hours upon hours, which is what drove me to take the plunge in avoiding grains, refined sugars, and vegetable oils. So many accessible, informative articles. Check out this one as a starting point: Welcome to Mark's Daily Apple.
So are you in? Are you ready to give one month of primal living a try? Post a comment if so!
