I started "intermittent fasting" last year after seeing Jason Fung's "Aetiology of Obesity" web series (available on YouTube). It made a lot of sense to me so I followed it up by reading his book The Obesity Code: Unlocking the Secrets of Weight Loss which mostly just recapitulates what's in the videos (but has all the usual advantages of books over videos). Since beginning IF, I've lost 50 pounds, easily, but I've noticed some people have a harder time with it than I do.

I read this book a while back and since then, I have spent more time researching and thinking about it. I have also followed some of the advice, fasting off and on for 12-16 hours.

I’m updating my review. His first book, “The Obesity Code” was far better. At the time that I read it, I felt that it was among the very best of all the diet books that I have read. Below are some of my observations/the problems that I have with this book.

This book uses flawed studies and flawed logic throughout. The main argument is fasting vs. calorie reduction for insulin control. I think it's very lacking that they don't talk about HEALING insulin resistance through a whole foods diet, rather than just controlling it using a ketogenic diet. The authors claim to support a whole foods diet but include many non-whole foods in their approach, completely ignoring intact whole grains, legumes, and fruit, which all help to heal insulin resistance.

Good explanations of different fasting protocols. I am trying to do regular 16/8 fasting along with two days a week of 24-36 hour fasting. I do agree that it is easier to fast than to eat a little bit or be on a low calorie diet. I have made peace with using cream in my coffee and buying bone broth rather than making it. Oh, well! I was ever the rebel :) We will see how my body likes this new plan because I honestly never thought I would fast successfully and now I find it is not that hard. I es ...more

Fantastic read! In June of 2016, I took a good look at a photo of myself taken by a friend on a hiking trail. Despite my efforts to eat well and stay active, I was nearly 170 lbs---way too much for my small frame. I started a low-carb, high fat eating plan (LCHF) to get the weight off. After 7.5 months, and over 32 lbs easily and sustainably lost, I discovered intermittent fasting completely by accident. Wanting more info on how it works and the benefits of it, I decided to give this highly-reco ...more

I borrowed this from my library, and promptly bought my own copy. I had read Dr. Fung's book, The Obesity Code, in October 2017, but was shocked and dismayed at the last chapter when, out of nowhere, he sprung fasting as the answer to obesity as a hormonal disease, absent any practical advice. "It's really very simple. I'm not saying it's easy, but it's simple." I was exceedingly weary of slim men pithily speaking about simplicity.

However. I harbored secret ambitions to fast. And secretly tried.

Best Book on Fasting & Why It works for Fat Loss & Curing Diseases

This is one of the best books on intermittent fasting and clearly explains why IF works for fat loss and curing diseases.

So, if you're overweight, obese, thin on the outside fat on the inside; or, you're pre-diabetic or type 2 diabetic already; or you have high blood pressure; or, you've tried every diet known to mankind, here is your answer: Dr. Jason Fung and intermittent fasting.

This was a good primer about fasting and insulin levels when we eat. I don't agree with all of the author's claims. Call me old school but I still think and know for myself that calories in vs. calories out works.

A to mám zrovna tieto Vianoce pokojné aj po smere jedenia, nebolo žiadne prejedanie sa, zo sladkého som zjedla iba pár kúskov a pochybujem, že som niečo pribrala.

Everything old is new again! Fasting is experiencing a resurgence as a therapeutic modality and it's well overdue and sorely needed in our heaving sickly world. This is not just another diet book.
It is actually anti-diet and clearly outlines how we can kick the asses of obesity, diabetes and other such modern day afflictions that are causing so much misery, illness and early death. Dr Fung has my complete respect. With intelligence, curiosity, and passion he has concentrated his life's work on

This book blew my mind! I hesitate to talk about it because there is so many minconceptions and fears about fasting. I had them. And I still realize how weird that sounds to say a book on Fasting is cool. I don't know what drove me to listen to this but now that I did... wow... just wow!

Imagine you were told that for work you had to attend an all day training on pencils. Can you think of anything more lame!?! I think if I were given this book as an assignment to read that would be my reaction. B

This book is complementary and overlaps quite a bit with Fung's The Obesity Code. Even with that overlap, I thought it was excellently written with some more information and details on Fung's theory for obesity and why fasting is different than low-calorie and other diets. It's an excellent book for someone interested in getting started with fasting.
I will be experimenting with some of his ideas in the near future.

The basic concept presented here is simple, and incredibly powerful. People over the centuries have simply not had the availability of food that we have today. But our bodies are made to have times without food.

I have now fasted 5 times using the principles laid out here and it really is freeing if you have food habits that you can't seem to break out of or health problems. Wow!

This book is extremely informative with dabs of humor and excellent historical reflections. Big thanks to the authors f

Read this after reading Dr Fung's The Obesity Code. Apparently, I was 'intermittent fasting' the first half of my life. Unfortunately, I was lead down the path of you need to eat more often -- like 4 to 6 times a day -- and my weight ballooned accordingly. Glad to know that if I go back on the path my body grew up on, I may, MAY be able to reverse the damage caused by the Drs & nutritionists who meant well, but put me in a one-size-fits-all approach. If not, at least I know it's not only acc ...more

the author does a quite good job explaining the relation between food intake and weight loss. insulin plays an important role in distinguishing why some diets work and others don't. it's the most important thing i learned from this book! on the most part, the book is a very good introductory reading for people who wonder what fasting is, how to do it, and how it affects your body. as i'm experienced enough with fasting, i find the author's website more informative (further research findings).

I am an experienced faster, and in combination with a low carb, moderate protein and good fat lifestyle (no processed foods/sugar) I lost 25lbs and still able to keep it off for 2 years now. What Jason Fung shares in his books and on YouTube makes so much sense and I totally believe in fasting. But... I was guided through the whole process by a certified health practitioner. Intermittent Fasting for 12-15 hours is no problem (most of the fasting happens when you sleep anyway), but if you are thi ...more

we were so focused as a species at ending starvation that we've gone overboard with the amount and frequency that we eat. much like every other animal on the planet we are designed to be able to go for periods of time without food. nowadays, fasting presents an opportunity to reclaim control of your hunger, body fat, and reverse on set of most modern disease. highly recommend learning these concepts as every religion and ancient civilization had known before us the value sand health benefits of ...more

I first became interested in fasting in my teens. I did my first 36-hour water-only fast at age 16. For a period of time that year, I did a 36-hour fast every week.

In my adult years, I've done a few different fasts, from 36-hour fasts to a 5-day fast during which I had 2 glasses of fresh squeezed juice a day (greens, carrots, beets, apples, etc).

But it's amazing how time can get away from you. I've gone 2+ years without fasting at all before realizing how long it's been.

The information in this book is amazing. We've been lied to for years and finally something that makes sense.
In short - high insulin cause obesity and other health issues, high insulin leads to insulin resistance or type 2 diabetes which also leads to obesity. A diet in carbohydrates causes high insulin.
So in a nutshell carbs=(high insulin=obesity) + insulin resistance=obesity. I'm this formula makes no mathematical sense, but hey, I majored in English not maths.

Highly recommend anyone who fasts for religious reasons, but this book is about fasting for health reasons. I was intrigued and pleased. I think if anyone is suffering from diabetes 2, they need to consult their doctor, or contact Dr. Fung's office to take a serious look at your options. Apparently the same is true, according to the book, for obesity as well.
Our way of eating has become so out of whack and following the government guidelines do not appear to be making any progress in the way of
The science is very compelling, and I have to say that fasting works for me, and it's not quite as bad as I thought it would be. The book provides sensible advice on how to fast, and perhaps more importantly, why to fast, and it's certainly simpler than the 'calories in, calories out' methods (and Dr Fung explains why this does not work). There are some good documentaries around to stream (I watched one on Amazon Prime) which give more advice on the topic, and discuss the pros and cons.

Really interesting insight into the obesity epidemic and how eating patterns have changed in the past 40 years. Great tips and motivation for trying fasting and seeing its benefits- I’ve done a few while reading the book and found them to be insightful into my own habits and how they influence how I look and feel.

I have heard fasting mentioned here and there over the years and this was a great introduction to the health benefits and potential risks of various fasting practices.

It definitely makes me interesting in skipping a few meals and even trying fasting for a few days (for probably the first time in my life).

This is a really well written and easy to understand book on different ways and benefits of fasting. I came across this book after watching a youtube clip on Jason Fung discussing ways to reverse type 2 Diabetics. We all know fasting has been around for centuries so thats nothing new but the roll it can play in overcoming the damage our modern diets are doing to us is very interesting.
