This is a great book. It is easy to read and very informative. The author shares his personal experience with a low carb diet and he also provides a lot of information that he has gleened from reading many books on the subjecct. It is an easy read and you can finish it in a few hours. I would discount spookies remarks. The information the author puts forth is documented so you can do your own research. He makes no claim to be a doctor and states that clearly in the disclaimer at the beginning of the book.
