If new to eating primal, this is probably one of the worst books on the subject. The author spends 50% of his time bragging about how great his stats are and claims to be an expert on absolutely everything when he is truly only an expert on half of what he preaches about.
I have been eating primal for almost a year with fantastic results, but reading this book almost dissuaded me from the diet simply because of the fact that I wanted to slap the author the entire time.
There are better resources, with more honest voices available. Don't waste your time with this one.
