The Obesity Code: Unlocking the Secrets of Weight Loss (Why Intermittent Fasting Is the Key to Controlling Your Weight)

If you’ve spent years wondering why you haven’t lost weight despite calorie watching, this book’s for you. It’ll introduce you to a fresh new paradigm. It’s not just another weight loss book. It’s a must read!

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!

Everyone should read this book.

Put your doubts to one side and trust the information in the book. I have lost 20kg and my partner has lost 41kg and we’ve both kept the weight off! Buy it now!

This book did not come to me in a brand new condition

Life changing book. Opened my eyes to insulin and how to bring it down. Lost 20lb in 6 weeks by following Jason Fung guidelines

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!

Zeer goed boek Leuk geschreven en een eye opener

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!

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.

I have spent over 40 years practicing medicine in the trenches and I have spent much of this time managing patients with metabolic disorders and obesity. I have published on topics related to obesity in peer reviewed journals, lectured at Harvard and other venues and I have relationships with many of the top nutritional researchers in the world. I thought I knew just about everything there is to know about obesity, that is until I was literally blown away when I read Jason Fung’s book “The Obesity Code”. I now know what the term “back to school” really means. In this outstanding book Dr. Fung first outlines the history of obesity and how we went astray with the faulty calorie concept and “fat is evil” mantra. Up until this point I was familiar with the sad historical information that he presented. He then carefully outlines the biology of obesity, focusing on two key parameters: insulin and insulin resistance. Although I was somewhat familiar with both topics, he presents them in a way that makes perfect sense, both from a clinical and biological standpoint. Each statement is carefully referenced so the reader could go to the source to learn more. Dr. Fung has a very fluid writing style and his concepts are presented in such a way that both medical experts and novices can easily follow his thinking. When it comes to solutions he presents a well cited summary of the healthiest foods for us to eat and I was already fairly familiar with most of this information. I must admit that in the past I tended to focus on glucose levels because they are easy to measure and follow, but Dr. Fung convinced me that the focus must be on insulin. For example, like most clinicians I had been teaching my patients about the glycemic index and load, which reflect the relative glucose response of various foods. Dr. Fung recommends using the Insulin Index because some foods that do not raise glucose do significantly raise insulin levels and as he points out, it is elevated insulin that leads to obesity and type 2 diabetes. He also points out that in addition to carbohydrates, both protein and fat can sometimes raise insulin levels. For me the most important information in this book is the absolute importance of separating the glucose response from the insulin response to eating. The other important take home message that hit my brain like a sledgehammer is the issue of timing of meals. I hate to say it but until I read this book I never gave the issue of timing of meals much thought. Dr. Fung weaves a fascinating tale about how the timing of eating is the key to reversing insulin resistance. He outlines how intermittent fasting can be easily incorporated into any treatment program to manage common metabolic problems. I should have figured this one out on my own. When I married my Greek wife I also joined the Greek Orthodox Church and as he points out these folks are the masters of intermittent fasting. And by the way, don’t make the mistake of measuring your progress by weight loss alone. There really is no such thing as a “weight problem”. Obesity is defined as excessive body fat so the most accurate way to measure progress is by measuring body composition. Because this type of measurement is not easily available to many people, I recommend keeping tabs on your waist measurement at your belly button. You can also get a rough idea how you are doing by how your cloths fit. If you are noticeably shrinking you are likely losing fat even if the scale isn’t changing much. To summarize, all I can say is if you want to be healthy in today’s world loaded with endless amounts of toxic fake food, you need to read this book. And if like me you also want to read the second best book out there related to diet and health, re-read “The Obesity Code”. It’s so chock full of great information that it’s almost impossible for all of it to sink in on the first read.
