Something I read today made me suddenly realize that there IS a difference between the Paleo and primal styles of eating. Upon further research, I discovered that Paleo sticks strictly to the foods our ancestors would have eaten before the dawn of agriculture (evil, evil agriculture). Primal is a bit looser. It emphasizes those same foods but also allows a few things that, while they wouldn't have been available back then, aren't particularly harmful. The primal folks are big fans of grass-fed butter, for example. And—more to the point—they say that for a small treat, there's really nothing wrong with an occasional bit of cheese or dark chocolate.
Now we're talking!
It's funny, but I think eating this way for a month really does change your way of thinking. To me right now, a square of dark chocolate sounds like a huge, reckless indulgence. A peanut butter sandwich sounds crazy and dangerous. Cake with frosting is completely out of the question. I don't even know who I am anymore.
