ok, here's my take - I honestly believe that there is a lot of wisdom in the idea that we should eat the foods that we evolved eating - we evolved eating a lot of various vegetables, fruits nuts, raw grains, meat and fish. we didn't evolve eating a diet of 90% cooked refined grains, which is where most people were at 100 years ago. that said, I don't follow a paleo diet, but I try to eat very little processed foods, and not very much refined and processed grains. I think that being too fanatic about it isn't good, either. and I am not sure that it is the best tool for long term health or weightloss. Fuck it, I like pasta and lots of it. However, I balance that by hitting the gym hard, getting lots of raw fruits and vegetables and over 1 g of protein per lb of body weight a day.
