Summary

We are in the midst of an obesity epidemic, but despite being inundated with diet advice we are only getting fatter. We count calories and exercise regularly, yet still the pounds won't budge. Why?

In this highly enjoyable and provocative book, Dr Jason Fung sets out a groundbreaking new theory: that obesity is caused by our hormones rather than a lack of self-control.

He reveals that overproduction of insulin in the body is the root cause of obesity and obesity-related illnesses including type 2 diabetes and offers robust scientific evidence that reversing insulin resistance is the only way to lose weight in the long term.

It turns out that when we eat is just as important as what we eat, so in addition to his five basic steps - a set of lifelong eating 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.

PLEASE NOTE: When you purchase this title, the accompanying reference material will be available in your Library section along with the audio on our desktop site.

Too much problem, too little solution...

A whopping 90% of this book is dedicated to proving history wrong. Jason May be correct in his analysis, but for someone who has spent his adult life looking for practical advice (that works) I found myself frustrated.

This book I think is aimed at doctors who see an epidemic of obesity and want some evidence to argue with colleagues on what the best approach to fixing it is.

For the ‘man in the street ‘ struggling with obesity he advice in the last 2 chapters boils down to:

1. Reduce added sugar
2. Make sure any carbs you consume are from ‘whole foods’
3. Implement a 24 or 36 hour fasting regime

Most of the practical steps outlined here are to be found in better forms on the internet.

Leave the other 90% of the book to the doctors and scientists...

Spoiler: Crack the Code by Intermittent Fasting

This was the clickbait of books. In short, he says insulin causes obesity and intermittent fasting is the only way to reverse insulin tolerance.

Repetitive and long winded

Although the science may be sound, he takes far too long to explain it, doesn't get to the point until near the end and is very tedious to listen to. Very disappointing, not suitable for audible and I've returned the book!

Superb and a Game Changer.

I cannot recommend this book highly enough. The detail and the in depth explanations of physiolog and aetiology of obesity is second to none in my opinion. The delivery of information is set out in such a way that you cannot fail to understand the implications.

An extremely methodical written book. Repeats itself just enough to get the point to hit home. I listened at the slowest setting to absorb it more readily.

I have total Faith that Dr Fung has done his research and constantly refers to academic papers and critically analyses them in a manner that I would do myself. This gives me the confidence to trust his opinions without me having to spend the time trawling the internet looking for others opinions. I still do that but after reading the book I already know the answers.

It really is exceptional and would recommend to anyone not just to people trying to lose weight or cure their diabetes.

The narrator is also absolutely superb. This is how I would imagine Dr Fung reading it himself but possible better as it is minus the "right" after nearly every sentence. Just a small critique after Listening to lots of Dr Fung podcasts and YouTube postings.

All round 5 stars and intend on listening to this repeatedly until the belly fat has gone!!

Best read if you’re looking for weight loss.

Finally someone who knows what he’s talking about, instead of trying to sell me something.

Also very well read.

It makes good sense

This book is a literature review on the science of dieting and basically it concludes that sugar is really bad for you; that high insulin levels cause you to become fat and are somehow involved in deciding your 'set weight' ; and that fasting between meals, skipping meals, and extended fasting resets your set weight and lowers your insulin.
After reading it I was much more selective in my food shopping and I was shocked how much sugar is in everything. It is difficult for people to maintain a healthy weight when 80% of supermarket food is unhealthy and will make you fat. I am skipping breakfast and I've reduced sugar by avoiding processed foods including bread and so far I've lost 8 lbs.

HARDLY EVER LEAVE REVIEWS, BUT HAD TO FOR THIS

If your diets have worked, plateaued, then failed and you've gone back to your original weight (or heavier) read this!

I was always thin in my youth (a size 8, 7-stone teenager). Then, as the decades passed, I got heavier and heavier. In my twenties: 8 stone. Thirties: 9 stone. Forties: 10 stone. Then, approaching fifty, I got on the scales to find myself at 11 stone. That may not sound that heavy but I never got used to the rolls of fat around my stomach, how much harder it was to exercise, how much more cellulite I had. In general, I didn't feel good. And if I kept going, by 90 I was going to be 15 stone and probably dead!! :)

Throughout my thirties and forties, I have tried EVERY diet there is: Weight Watchers, The Cabbage Soup Diet, The Ketogenic Diet, The Atkins Diet, The Juice Diet. I've run for an hour followed by an hour's swim three times a week. I've tried Paul McKenna's I can make you thin hypnosis. Even some crazy guy's advice to pretend you're running from a tiger before you go to sleep at night!!! You name it. I've done it. On each diet, I'd lose 3-7 lbs, plateau, and then put it all back on again, adding another 14 pounds every decade.

I thought I was doing something wrong. I'd feel myself slipping on these diets that weren't maintainable in the long term, and blame myself.

Then I found this book and everything fell into place.

I read this a month ago and gradually built up my fasting regime: 12 hours, then 24, then 36. This week, I've gone 4 days without any problems at all. I make the broth, I take vitamins, I drink lots of water and tea. But I break the rules a bit too. I drink a lot of milky coffee (instead of coffee with cream which makes me retch after drinking that too often on the keto diet) and I still treat myself to a low alcohol beer or two at night.

And even without following the rules to the letter, I've lost 14lbs in a month.

Finally, my weight has taken a turn.

Just buy this book! Best thing I ever did! Best book I've ever bought.

Thank you, Jason Fung.

Can be a bit scientific, but overall a good listen

Jason has some great observations about our eating habits and how they get bad. Ultimately he recommends fasting, having tried it I have to say he is correct - but trust what your body tells you.

Superb content, excellent narration

This book is brilliant, it offers all the scientific backup and research studies that you would expect if you’re asked to buy into a certain view and is described in an easy to understand format.
I’m a Personal Trainer and it has helped to reinforce my understanding of how the body processes food. It gives a well rounded holistic view and I can’t recommend it highly enough!

Excellent Book

The best book on obesity ever. Clear and concise and scientific. Makes so much sense. I think the insulin story is the best part. Only trouble is that 70% of insulin secretion is genetically determined and only 30% is under our control :-( Would be nice to be able to access the forward by Tim Noakes and the tables on fasting which are inaccessible on the audio book.

I actually started with the book, but switched to the audio version halfway, and it actually felt like it was Dr Fung narrating. Very good. Thank you.

Insightful book about Healthy Living and Lifestyle

I really enjoyed the book. The message in the book makes a lot of sense. For someone who is not patient, they might see the beginning of the book to be less interesting and too medical or too much deep dive into some sections. But I later understood why the deep dive initially was important to understand after moving along further into the book. I can recommend this can be by far the best book to help you understand if there is anyone trying to understand the formula of healthy eating and weightloss challenges or plans

Such an insightful book

There’s so much research dispelling all the diet myths we’ve been fed. Jason Fung does a sterling job of putting all the facts together (from reputable publications) and identifying the underlying issues causing obesity.
Such a great book. I highly recommend it!

Very informative

I found the book informative. Sometimes a bit too technical for my non medical background but clearly the author has done his research and has exceptional knowledge on diets and the history thereof. A bit too much repetition in general, and would have like more information on Intermittent fasting.

Game changer

Wow - this book has made me absolutely re-evaluate my approach to health. This was so interesting and easy to follow and I really enjoyed the narration. Thank you Dr Fung - I learned so much in the time it took me to listen to this book especially about insulin resistance. So much suddenly makes sense.

Good book, equally good narrator

Brian Nishi reads very well, so easy to listen to him. I really enjoyed the book. Just wish all Dr Fung’s books were read by him!
