Hi, All! I am following the Primal Blueprint which is derived from the Paleo Diet. The book suggested using FitDay. I have been doing this now for about 19 days. So far, really good. Exceptions - I had a couple of Shiner Bock beers last night with my husband and the other night at a business dinner I had a couple of bites of bread pudding - other than that I have been very faithful. It is hard to think about moving away from a grain centered diet at first, but once you get the hang of it, it is easy and makes you feel so much better.
The Primal Blueprint, by Mark Sisson, a former marathoner and Triathelete, also proposes a less is more approach to fitness - high intensity but for shorter durations with adequate rest - very Crossfit style. I do crossfit workouts (except for the Olympic lifts which I find inimidating) P90X and recently found Body By Fish, which is new to me, but a very cool system of intense workouts using mostly body weight exercises.
I hope to see you around on the boards with your experiences and advice.
