Why intermittent fasting is the key to controlling your weight

The landmark book from New York Times-bestselling author Dr. Jason Fung, one of the world's leading experts on intermittent fasting for weight-loss and longevity, whose 5-step plan has helped thousands of people lose weight and achieve lasting health.

"Not only full of insights but also surprisingly funny. Read it to understand why the world became fat, how to reverse the epidemic-and how to stay thin yourself."
-Andreas Eenfeldt, MD, Founder of dietdoctor.com

Everything you believe about how to lose weight is wrong. Weight gain and obesity are driven by hormones-in everyone-and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss.

In this highly readable and provocative book, Dr. Jason Fung sets out an original, robust theory of obesity that provides startling insights into proper nutrition. In addition to his five basic steps, a set of lifelong habits that will improve your health and control your insulin levels, Dr. Fung explains how to use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight-for good.

Product description

Review

“Not only full of insights but also surprisingly funny. Read it to understand why the world became fat, how to reverse the epidemic—and how to stay thin yourself.”
—Andreas Eenfeldt, MD, Founder of Dietdoctor.com

“Dr. Jason Fung’s explanation of insulin resistance and the accompanying insulin model of obesity is original, brilliant and game changing.”
—Zoë Harcombe, Obesity researcher, author of The Harcrombe Diet

“A fantastic book that exposes some of the world's most pervasive myths about obesity and weight management. A must read for anyone interested in the science of diet.”
—Kris Gunnars, nutrition researcher

“In The Obesity Code, Dr. Jason Fung triumphs in explaining the core underlying causes of obesity and manages to simplify it in a way that anybody can understand. If more doctors and people were able to understand these causes and implement Dr. Fung's actionable advice then we would be able to start reversing the obesity epidemic tomorrow.”
—Sam Feltham, USA Today World Fitness Elite Trainer of the Year

Mind Blowing simple way to lose weight if you are obese

Mind Blowing simple way to lose weight if you are obese
A dear friend recommended this book, citing that she hadn’t read it but everyone she knew who had said it was “earth shattering” and “completely revolutionized and debunked every diet myth”. I thought, impossible! So I bought it and read it and now am totally in agreeable! I even got buy-in from my family doctor to follow my weight loss as I tried intermittent fasting as a new way to shake things up. The surprising simplicity of “listening to your body” and only eat when your body actually needs to, is so counterintuitive to our society’s cultural norms of 3 meals a day and constant snacking. The basic premise of Dr. Fung’s years of research findings was so simple, our bodies are revolutionary geniuses. We have survived periods of long famine and short feast for centuries because our bodies are designed to store energy (aka body fat) to help us survive. So why not use this mechanism to lose fat? Try not eating voluntarily (aka fasting) Mind Blown!!! If you have excess weight, this method is genius and really not hard. The book explains why that is and how to get over pangs of hunger and cravings. Also not very hard. Spoiler alert, ignore them, distract yourself or have someWater or bone broth and you will survive!Goes well with the The Intermittent Fasting Guide.

This book is THE only book that you will ever need to understand why you are not getting any results on this diet, that diet and the whole cutting calories 'theory' ... Dr Jason Fung really breaks it all down in a language that you will all be able to understand. No waffly hard to grasp concepts. He has some great podcast appearances too ... a serious legend in the medical field, and responsible for turning so many peoples lives around and even saving people by improving their metabolic health !

4.0 out of 5 stars Easy to follow, fact-based, not shaming, & genuinely helps
Reviewed in Canada on May 16, 2019

This book is amazing. I've been starving myself & beating myself up for having no energy to lose weight! Of course I have no energy: I'm hungry. I starve myself, lose some weight, then quit my diet because I'm starving & have no energy. This book points out that exact classic cycle, tells you with easy-to-understand facts that it's not your fault - because all the crap we hear about weight loss is wrong. Since I've been reading this I've been staying away from the scale (or as I call it: the shame scale) & so I don't know if I'm losing "weight" but I'm getting leaner & healthier! So I really do feel like it's working, but it is a lifestyle change for sure! It's much easier than I thought it would be though & I feel good, which is rare for most diets. I highly recommend this book! Should be required reading for anyone who works in health care.

Finally the facts on how your body works. It all makes complete sense and requires no cost in any way to achieve your desired results. In 7 days my blood pressure is 121/73 and have now dropped 2 meds at 65 yrs old. No more drowsiness and so much energy. All the fat is literally melting into the sunset. When you know the truth that your body will not utilize muscle for energy until you are around 4% body fat.... you no longer equate a hunger pain with possible muscle loss. Instead you think this isn't really a hunger pain, it's just my 30, 40, 50 pounds of stored glucose in the form of fat is now being utilized for energy. Exactly what I want. How could it actually be a hunger pain carrying all that excess energy around....? Kinda funny. Just a shift in thinking more aligned with the truth about your body's design and function. Truly freeing information. I am so happy and becoming more liberated everyday from the self imposed prison of excess weight. All from not knowing how it all worked and now following a easy method of weight loss. This book should be mandatory reading in grade 9. I started at p.155 section 5. What's wrong with our diet?

Such a well researched book on the causes of obesity. The studies mentioned are all reputable, over years and hundreds or thousands of subjects. None of these food studies done by manufacturers promoting so called health benefits while stuffing their products with sugar you don't know is there!
I am trying the intermittent fasting recommended and find it definitely worthwhile.
This is quite a long read but so worthwhile for anyone who yo yo diets, in fact for anyone struggling with their weight.
Highly recommended.

This book I strongly recommend for all those who suffered from the diet industry.

It shows a very in-depth analysis of the history of diets and how the government and big food industry are making us obese.

It also talk about intermittent fasting at the very end, and what your body needs to break the obesity pattern

I am now on a 16/8 fasting pattern and feel super good This book really changed my perspective on food and how much I eat. less

3.0 out of 5 stars Like any other diet book with a meal plan at the end
Reviewed in Canada on July 10, 2021
Verified Purchase
I really enjoyed this book. Very informative and thought provoking. What disappointed me in the end was the suggested meal plans in the last chapter. Ugh. As soon as I saw them I was upset that I clearly just read another diet book. The "eat" days were super low carb items which couldn't have added up to much more than 1200 calories. Meanwhile, the book makes it clear several times over that cutting out or severely restricting any type of food is the reason mosy diets fail. Hence why I was surprised the non-fasting days were not almost completely open to all food (yes, even ice cream or pasta).
I give it a 5 star for information and the promotion of self-reflection, but I give it a 3 star for saving the truth till the end of the book. Basically, if you've done phase 2 of The South Beach Diet, you will be pretty much doing that if you follow this book. Fasting alone is not the secret to weight loss unless it's paired with....you guessed it! Healthy eating!
