The book is packed full of tested results. They were tested on Timothy himself. He didn’t rely on the options of doctors to write this book. I was and still am on the keto diet. All blood work is good, I was I was loosing weight 38kg and everything stoped at stand still on weight loss. I started to read this book and he had many suggestions and I started loosing weight again. During my weight loss journey, I was complacent and did not even realize what I was doing wrong. This book opened my eyes, I was the problem by not following the rules. I am not even done with the book I have only read 16% of the book. This book is worth every cent it cost. I would have to thank Tim for all his hard work and testing that went into this book. I recommend buying it.
