I'm writing this review 18 months after reading the book because after this time I can conclude that it's been life-changing. On the book itself, I'd say it was a fascinating and compelling read. Fung clearly explains quite complicated physiological mechanisms and provides evidence that I found very convincing (with one exception). 18 months on, the bits that have stuck are not the complicated issues but simply: 1 My body, and especially my liver, needs a regular rest from eating and from the constant blood insulin levels that frequent eating produces. 2 I'm probably stuck with whatever level of insulin resistance (and consequent stored fat) that developed through my adult life (I'm over 60) but I can help prevent further damage. 3 I shouldn't feel hungry when I fast intermittently (This was the life changer for me because I found it's true!). 4 Try to avoid discussing your intermittent diet regime with family and friends. They will simply go on and on with the usual uniformed diet rubbish that I used to believe myself.
The one exception in terms of evidence, was the value of cider vinegar. I wasn't convinced by Fung's evidence, so I haven't tried it.
So, how has the book changed my life? I haven't lost much weight but nor have I really tried to. I have lost about 6 pounds over 18 months but importantly this is against a history of putting on a pound or 2 every year. What I have done is put 'breakfast' back to 7pm or later every day. I only consume water or black coffee/tea up to that time. And the magic part is that I don't feel hungry even when sitting with others who are eating scrumptious meals. So, it doesn't require any willpower! If it did, I couldn't have sustained it. I still feel amazed and empowered every day when I realise that I haven't eaten for 19-21 hours and I don't feel hungry. As Fung points out its easy and its free!
In May this this year my diet was put to a pretty tough test. I cycled the North Coast 500 over 9 days. This is a challenging and hilly route, averaging about 57 miles/day. I didn't expect to stick to my fasting regime but over 15,00 miles of training in 11 weeks before the trip (60-85 mile days) I discovered that it was not a problem! I added calorie-free electrolyte replacement to my water bottles and never experienced dips in energy due to low blood sugar. With that now behind me I am as confident as I can be that I won't need or want to change my eating pattern in future.
This book gave me a basis for trying something that flew in the face of a received wisdom that had me trapped in a cycle of eating and craving, which seems to be the common experience of almost everyone I know. I would strongly recommend it as a serious contribution to better understanding of the effects of diet on insulin release and the effects of excessive insulin release on long-term health.
An excellent book - life changing! It made we wonder 'Why has nobody told me this before - I've been torturing myself needlessly for years!' It makes so much sense and works! I've lost weight already and feel fab and NOT hungry. I'd recommend this to anyone and everyone.
I came across Dr Fung by chance on a well known video site. Within a few minutes of the interview I knew Dr Fung was the "real deal". The prinicples he teaches are so obvious and really so simple we should be following them as self evident but some how they are too obvious and we miss them. I immediately began applying the principles that he discussed with Dr Berg and I began to see the scale heading in the right direction finally after so many years of misery and feeling hopeless. I finally have control of my weight and this control cannot be underestimated after so many years (20) literally ballooning out of control whilst not eating very much. My adult years, when i should have felt at my best have been miserable and i have felt unwell and depressed for most of them.
I purchased the book as a thank you to Dr Fung, and also I wanted to delve deeper into his theories. I did pick up a few extra details that I may have missed from the lectures and now the needle is moving even quicker south. I was about to give up on myself and just accept that i am just a 15 stone person. I no longer have to do that and Dr Fung gave me back hope after so many years despair. I can now see my proper shape emerging in the mirror and I fully expect I shall be at my optimal weight by christmas.
Thank you Dr Fung. You are quite literally a saviour.
I have recommended this book to others who are also seeing remarkable results. I cannot recommend this book highly enough. After a lifetime of dieting, i have an extensive collection of diet books. Many have worked for a short time, but are not sustainable. Fung's method IS.. My bookshelf will be cleared of the redundant ones and time now to learn new things rather than always looking for the next diet.
Quite a revelation! Well written and clear, with a touch of humour. It explains why low fat/low carb diets don't work - and why I feel so cold and irritable when trying to lose weight that way. And offers a different approach .... watch this space!
Enjoyed the book. Mentions most things captured during his YouTube speeches. Most of all, I've followed the advise & boy does it work. Never lost weight so easily and kept it off. And I don't feel like in dieting.
This book is life changing. If you are obverweight, you need to read this. Fung gives clear explanations backed up by rigerous science as to what causes obesity and a simple remedy that is so effective it can even reverse type 2 diabities. I have been trying to loose weight for decades and nothing works in the long term. I got hungier and heavier. Now the weight is falling off and the remedy is much easier than you would think. Im no longer hungry all the time and have a new enthusiasm for my meals. Get the book
I have not been able to put this book down. Having used intermittent fasting and removed processed sugars and grains from my diet, this book brings all of those elements together, backed up by science. Now to try apple cider vinegar!
For those wanting to know what the hell is going on with their bodies, this book is key. If you've ever watched Dr Fung give a talk, you will know he speaks in terms we can all understand; and that is how this book is written. It gives people a real understanding of the mechanisms that cause obesity, and the failure of conventional wisdom (the calories = calories out model) and guides the reader to an understanding of the methods he uses in clinic that actually lead to weight loss that works over the long term.
