I don't care for it.
I feel the human body was meant to adapt to various eating patterns. In fact I was reading a great article on an archeology blog (let me know if you want the link), dated 12/10, where they were discussing new finds about how Neanderthals liked sweets and ate carbs. They found dates and barley remnants stuck in teeth fossils.
So much for paleo not allowing dried fruits and grains!
I am following the ABS diet and love it. That said, I did give Paleo a try a while back. (As you can see, I am interested in archeology). It was extremely restrictive and just not for me.
