The best thing about this book is the recommendatio to take before and after pictures...

I don't know where to start...
The avoidance of junk foods is great, but they are present in the serving size list that is based on your hand... chips, pretzels, etc. I'm not sure why that is, since according to this book you will never need to measure these because you should never eat them.
The amount of carbohydrates that you need, particularly when you are exercising at a high intensity (which is what Crossfit does pretty exclusively), increases dramatically. A 40% carb diet is simply not optimal, and peer-reviewed research conducted on a variety of subjects, from Olympic level athletes down to normal people, shows that being in the 50% to 60% range is what you really need.
The protein chart is creative, and not awful, but also neglects a very important concept: When you restrict carbohydrate intake to below that which your body requires, the rest gets made out of protein. In this scenario, which is what a Zone diet puts you in, you actually need more dietary protein than they list (especially when trying to lose weight, and specifically body fat, due to the increased lean mass sparing effect), but this is a stupid situation to put your body in, so it shouldn't be an option to go so low carb with such a high intensity lifestyle.
The other single star review is correct... this isn't a Nutrition guide. It's a poorly hacked-together paleo zone template that neglects to follow the dietary guidelines that produce the best results in real, live athletes.
Just because what they suggest is better than what you currently practice does NOT make it the ideal solution... it just means that your diet is LESS s****y than it was before. That's technically a step in the right direction, but why spend your money on a half-assed book?
Eat whole foods, have ~20-30g of protein and at least one heaping cup of cooked veggies at each meal, remove processed carbohydrates from your diet (and replace them with whole food carbohydrates), and drink more water, and you'll accomplish more than this book will guide you into for free.
