Shame more doctors are not up to speed on the latest findings. I was diagnosed as T2 diabetic, put on metformine, and would still be deteriorating had it not been for Dr Fungs work. After following a keto diet, and intermittent fasting, 8 months later I am no longer on medication, and my diabetic markers are back to normal. This book may save your life!

This book is an eye-opening truth about weight loss and gain
I'm shocked by how brainwashed we have been, Dr Jason proves that obesity is NOT a caloric imbalance. It's a hormonal imbalance and it's a multifactorial disease. I recommend it!

Great for anyone interested in weight loss
Excellent book for anyone looking to lose weight and potentially solve health issues. Easy to read, but explains diabetes and obesity very thoroughly. A must-read!

Leitura excelente pra quem enfrenta a obesidade
Já tentei perder peso - e perdi - pelo menos 3 vezes na minha vida. Sempre consegui bons resultados, mas dentro de um ano o peso sempre volta, e com reforços. A culpa sempre fica do lado do obeso, que se esforça MUITO mais que qualquer outra pessoa sem tendência a acumular gordura, mesmo comendo uma fração do que pessoas magras comem. A abordagem do Dr Fung é clara, se baseia em estudos científicos e oferece um novo paradigma pra se entender a obesidade e tratar sua causa original, e não aparente. Deveria ser leitura obrigatória pra professores de academia, nutricionistas e médicos que lidam com pacientes obesos.

This book is a must read for all
I have read Dr. Fung's website (Intensive Dietary Management) and seen many of his interviews on YouTube. You can get almost all the information from those sources as what is in this book. But this book is still fantastic. Dr. Fung explains that insulin is the driver of weight gain. Dr. Fung is a kidney specialist treating many patients with Type 2 diabetes. He has seen first hand the effect insulin has on the body. The strengths of this book. Part 1: Explaining insulin and how it is not (always) the same as blood sugar. This was surprising to me. Low-carb is in fashion now but doesn't mean we can eat unlimited protein. He also spends a lot of time talking about a body's set weight by homeostasis. Part 2: Fasting is a great way to reduce insulin levels. Dr. Fung shows how it is safe and can actually make us more productive. Another big point I took away from this book is that you don't need to fast for a week or even 24 hours. You just need to fast after meals. This means no snacking. Dr. Fung does give some scientific explanations did I have to work through a couple times but it is not wholly necessary in understanding his message. He cites study after study of peer-reviewed, non-animal research to make his case. In the end, the case is made to the reader to be mindful of their insulin levels. This will help lead to health and sustained weight loss for those in need.
