I am a doctor and have been using the Keto Diet in my practice for about a year. This book was referred to me by my friend and peer. He has been suggesting his patients purchase this book and follow Dr. Bosworth’s protocol. I bought this book at his suggestion and was amazed at how Dr. Bosworth has simplified the complexity of how the body works. If you have ANY heath issue read this book. In the year I have been using Keto in my practice I have seen diabetes, thyroid issues, auto-immune disorders, and cancer reverse course. My only complaint is I would like to see this book offered in Spanish. Dr. John D’Amanda
