Little to no added value. Preaches to the converted.

The book lacks justification for what is being stated. It all comes down to "trust me, I know better". Most if not all the chapters are stuff that have been know for a long time. Additionally, if you come from hearing the author in talks on keto/0-carb circles, then you probably know way more than what you get here. You won't change anyone's mind by recommending this book nor will you get additional knowledge, I really don't see the point of the book. Definitely not worth paying for. The cherry on top is that the author recognizes this surface level content and tells you that it is YOUR job to go get to the actual information, that he is just tickling your interest. This doesn't make sense because already interested people are buying the book. You may as well listen to the author on Youtube for free to get interested and then actually go do something useful for you.
One last thing, a recurrent theme in the book is "Nature/God made so it is good". Regardless of your beliefs, this is an unproductive argument for many reasons. One of them is that you can justify pretty much anything. For instance, God made rabies, therefore rabies are good for us. You may complain that there must be more nuisance in the argument but no, this is as plain as you can expect from the book. An example from the book: "God made the sun, and God made you". Then the author uses that to justify that the sun is good for you. The sun may be good for people but this is just lazy arguing/writing.
Conclusion: the book itself seems like a quickly put together money-grab. Please, spend your money more wisely.
