There's some dubious stuff in the book and its total broscience. That being said, the weight loss chapter is very solid. I started using the "Slow Carb Diet" chapter in January and have had pretty remarkable results. I'm 5'9" and after Christmas feasting I weighed in at 184 lbs. I'm now 157 lbs. I wouldn't necessarily recommend buying the book just for the diet (though the whole book is a fun read). Basically the diet is: 1. Don't eat grains (rice as well as wheat is out) and don't eat starchy foods. 2. Don't eat fruit. 3. Don't eat dairy. 4. Don't drink calories (no soda, pretty much the only alcohol you can drink is red wine...I cheat with an occasional scotch). 5. Once per week eat whatever you want in any quantity to keep your metabolism up. He gives some specific meals to eat that were useful, (beans and nuts are a key part of his diet and usually omitted from other low-carb diets) but basically you'll be eating a lot of salads topped with meat. I coupled those rules with some moderate exercise (weights and cardio at the gym twice a week, running once or twice a week)...but not too much. I don't really love working out. For this diet alone, I like the book, though I think a lot of what is in there could probably be found elsewhere without the bro-attitude.
