I liked this book, for the most part. Jason Seib really seems to know what he's talking about. He doesn't just say "do this" or "don't do that"; he actually explains some of the science behind his recommendations for nutrition and exercise. One thing I really liked was how he says "you can't fix a body you hate". "(B)odies can be changed in remarkable ways, but the minds that hate them just get more critical." If you hate yourself, you're really facing an uphill battle trying to change your eating and exercise habits. But if you care for your body, it's much easier to make such changes.
A couple things stood out that I did not like. For instance, eating "(j)unk food will never compare to the envy your friends will have as you coast through life's physical challenges without breaking a sweat" didn't sit well with me. Focusing on what other people think of me does not help me like myself any better. Also, the pictures used for before-and-after were not always the best choices. Having studied media literacy in college, I can catch a misleading ad a mile away, and some of these pictures are not true comparisons - e.g., the before picture is taken head-on while the after picture is taken at an angle, which would make anyone look thinner. There are too many dramatic terms, like "for extraordinary health" and "an incredible body" that could be misleading. But if you look beyond that, it's an informative, interesting, and inspirational book. I would definitely recommend it to anyone considering or following a Paleo diet.
