I read the book not too long ago. Definitely some new information that I didn't see covered in other keto/paleo books -- especially the sections talking about how wheat has changed since early agriculture started. I also like that he emphasized that using rice flour or tapioca flour in place of wheat flour is really just the lesser of two evils.
All in all, I think the book is a good read but a bit longer than it had to be.
"There's no doubt that the Atkins diet will lower your cholesterol, weight and blood pressure and get rid of your diabetes, but then what?" asked Dr. Robert Rosati, the cardiologist who runs The Rice Diet Program Clinic, granddaddy of Durham's diet centers.
I guess there's really no pleasing some people.
