Update... Last week I had my A1C checked by my doctor. It is 5.6! This book works!
This book builds on the success of very low-carb eating as a therapeutic approach to type 2 diabetes. But it goes beyond that by advocating frequent prolonged fasts as a potential cure for diabetes. I'm talking about fasting for 30-36 hours at a stretch, for up to three times a week. On non-fasting days, his patients typically eat a low-carb diet, which makes sense to me. Two week-long sample meal plans are provided. Thus far, none of my patients have asked me about fasting. If the underlying science checks out, I'd seriously consider the Fung approach myself if I had T2 diabetes.
The longest fast I've done has been 24 hours. That's pretty easy for me, probably because I eat low-carb, so my fat-burning cellular machinery is ready for action. In bro-science terms, I'm keto-adapted. I have no idea if fasting 36 hours would be any harder than 24. Maybe it's easier if you're obese.
Dr Fung shares many clinical vignettes from his Intensive Dietary Management Program in Canada. He doesn't mention how many of his patients start the program and then drop out because it's too difficult.
Why the intermittent fasting? Because it seems to be an efficient way to reverse the fat build-up in the liver and pancreas that cause the high blood sugars of diabetes. That fat build-up, in turn, is caused by high insulin levels, according to Dr Fung's working theory of diabetes causation.
The author says this is what causes diabetes and prediabetes. First, remember that dietary carbohydrates cause a release of insulin from the pancreas, in order to dispose of the carbohydrate as an immediate source of energy or for storage in the liver and skeletal muscles as glycogen. If the carb is not needed for immediate energy and if the glycogen tanks in liver and muscle are full, the glucose is converted to fat. That fat is ideally stored in specialized fat cells (adipocytes), but can also be stored in the liver and pancreas (called visceral fat). Excessive fat in the liver and pancreas eventually impairs function of those organs. To prevent this overload, cells have to become resistant to insulin's effects. Diets rich in highly-processed, refined carbohydrates (especially fructose, sucrose, and starches) over-stimulate insulin release from the pancreas. Over time, this causes not only body fat, but also fat build-up in the liver and pancreas, impairing their function.
Intermittent fasting and very low-carb eating directly and immediately ameliorate the high insulin levels that cause diabetes. The fasting allows for extended periods of low insulin, which helps tissues regain or maintain sensitivity to insulin, he says.
Dr Fung rightfully points out that his program should be done under physician supervision, especially if you take drugs that can cause hypoglycemia. I can see patients taking this book to office visits and asking "Doc, can I try this?" Unfortunately, many doctors won't take the time to read the book.
I wonder if this manifesto was actually written to convince physicians that what we've been doing for years is misguided, and that Fung's approach is the way to go.
My favorite sentence: "...the very low-carbohydrate diet does remarkably well, giving you 71% of the benefits of the fasting without actual fasting."
My least favorite sentence: With regards to side effects (e.g., hunger pangs, muscle cramps, headaches) when starting fasting: "These side effects are often signs that the body is dumping its toxic sugar load." No, that's just good ol' "induction flu," more recently called keto flu.
I don't know if Dr Fung's causation theory of diabetes is correct or not. Maybe Dr Roger Unger's glucagon-centric hypothesis is the reality. Ultimately what matters is whether his protocol actually reverses diabetes in significant numbers of folks, and does it safely. If the Fung protocol proves widely effective, and I hope it does, a Nobel Prize in Medicine may be in Dr Fung's future.

Disclosures: I was given an Advance Reader's Copy of the book by the publisher's representative, otherwise I received no financial or other compensation. I don't know Dr Fung.
Potential conflict of interest: I am a diet book author and blogger who advocates Mediterranean-style eating and low-carb eating for the general public and diabetics.
I was a 307 lb dialysis nurse with a bmi of 40.5.
I was browsing my youtube feed and a lecture by Dr Fung popped up and I watched and I changed my diet and incorporated two 36 hour fasts per week. Now 95lbs lost later...
I was never diagnosed with DM2 but my fasting blood glucose was 104 when I began doing this and now it is in the 60s with no noticeable symptoms. Looking back I think I was for sure headed for a diagnosis of diabetes.
My patients constantly ask if I can help them lose weight and I can only recommend this book along with The Obesity Code. (I also advise them to consult their physician before beginning any dietary modifications due to the likelihood most of them are taking some type of diabetic medication.)
The advice Dr Fung gives in this book and The Obesity Code changed my life.
• Took BP meds for over 20 years and now none.
• Had chronic low T levels and at one time was taking injections every other week (got sick of the injections so quite taking them) now t level has normalized.
• I have chronic joint pain from osteoarthritis that I was taking copious amounts of NSAIDs before and now I hardly ever need them.
I purchased this book with the hope that I could pass it along to my patients. My only problem is as great as this book is I think it is not written for the average person. I also understand that as complicated of a subject like diabetes is it would be difficult to present this stuff in a more average reader friendly way.
Don't get me wrong though I'm still out there singing those praises...
Thank you Dr Fung.

= By having the correct foot checks, I will most likely keep my feet, as only the bit that had gone bad would need cutting off.
= That the eye checks will enable laser eye treatment to be done before I went blind.
= And that the dose of the drug could be increased if it did not work, and there were many more drugs that could be tried before I went on insulin.
However, I recalled seeing on the BBC “Doctor in the House” program that some people had been able to come off their drugs and get normal blood glucose levels. I, therefore, read the presenter’s (Dr Rangan Chatterjee) blog etc, this took me to a youtube video “Reversing Type 2 diabetes starts with ignoring the guidelines” Hence I discovered low carb diets……..
After reading many blogs (some written by Jason Fung on the dietdoctor web site), internet forums (Google “type 2 reversal”) research papers and some books, I learned enough to reverse my Type2 getting my blood glucose well into the normal level. But the learning took lots of time and efforts.
There is nothing in the book that I don’t now know, but it is explained much clearer than elsewhere, hence if I had this book when I was diagnosed, I could have learned everything I needed to reverse my diabetes in a few days of reading, rather than many weeks of self-directed learning.
Highly recommended for everyone with Type2 diabetes who has not (yet) returned to normal blood glucose levels without the need for drugs.
PS, using the methods in this book, I have got my hba1c down to 38 mmol/mol (5.6%) from 88 mmol/mol (10.2%) in under one year.
I was diagnosed 15 years ago and have had varying degrees of success and failure at controlling my blood glucose. I tried following the dietary advice given by my doctor even though i knew that carby food would increase my blood glucose. When I questioned this i was told not to keep testing my bg and to follow the dietary guidelines.
Of course i lost faith in the process, nothing made sense and it seemed there was nothing i could do to make significant changes. At each review if my weight was up which it frequently was, i was told to ‘eat less, move more’ . Dieting the traditional way (calorie counting) worked for a short while, whilst i could stick to it but it was never a sustainable option and the weight would go back on accompanied by corresponding increase my blood glucose results.
I have been put on a variety of drugs over the years, none of which have ever done a great deal to improve my diabetic condition. Some have been a total disaster. I was on Byetta for a year, yes i lost weight, it brought my fasting bg down to around 7 to 8 which i was told was great but i felt sick and ill every single day for a whole year. This was not progress. Gliclazide was a complete disaster causing me to gain around 20lbs in 2 or 3 months. Metformin meant i couldnt leave the house due to the constant diarrhoea and eventually that gave way to Glucophage which was on marginally better. 18 months ago my blood pressure was rising so ramipril was included in the mix along with the terrible Atorvastatin
Finally in January this year, on maximum dose Glucophage my hba1c was at 88 which equated to a bg level of between 13 and 15 , insulin was on the cards but a last ditch attempt was made with empagliflozin which didnt last long due to the continual thrush and bladder infections this drug caused.
I needed another solution, and by some fortune came across the name Dr Jason Fung. I looked him up on Amazon and found this incredible book The Diabetes Code. I always believed that type 2 diabetes was high blood glucose because all the drugs are aimed at reducing blood glucose. I was truly shocked to discover that high bg is not the disease, its just a symptom of the disease. Doctors are not treating the disease they are just treating a symptom.
No wonder i was making no progress with it. Dr Fung gave an analogy of walking into a coffee table and bruising your leg. Doctors treat the bruise, pharmaceutical cos look at ways of making a drug to treat the bruise. The answer isnt to treat the bruise, the answer is to move the coffee table.
Dont treat blood glucose, treat the cause. Diabetes type 2 is a dietary disease, too much carbs and sugar cause diabetes t2. It does not need a drug, it needs a change in diet.
Dr Fung is a great proponent of fasting, this sounded like something i could not do and in fact it took a while to get there but it wasn’t difficult. I quickly and easily dropped into 16:8 then into eating once a day. Once i got there it was an easy step to doing a 48 hour fast which i now do once a week. Fasting is the most powerful way to bring diabetes t2 under control, and will rid your body of excess glucose like no drug can. It also rids your body of excess dead cells cleansing it naturally.
As i said in January the meds were not working and insulin was on the horizon. Within 8 days of a ketogenic diet my blood glucose was down from 13 to 6. Within 6 weeks i stopped all my meds. I had my hba1c done early august just 2 months into this way of eating and my hba1c was at 44 which is in the non diabetic range. And ive lost 46lbs. And i never get hungry even though i eat only once per day.
I have so much energy now, i feel great, my skin looks great, i feel healthy. Thank you Dr Fung
For Health Care Professionals this book will open their minds (if they have open minds) as to what they maybe have been mis-taught in the past and how to rectify this to help their patients get better.
For Pharma companies.. be afraid... be very afraid....
Dr Fung has a great way of explaining science to make it understandable by all. There isn't any complicated jargon or long words to confuse the issue. Things are explained using worthwhile analogies that can help with comprehension.
I'm a bit biased because I credit this guy with transforming my life and health as well as helping me to recover from the Type 2 diagnosis I received 2 1/2 years ago. He literally saved my life.
Buy this book!
The first few pages are a beautiful summary of the problem and what to do about it. You could stop there if you just want enough information, but Fung writes too well for that. If you have a doctor or nurse who seems like they actually want to help people, and not just repeat advice that has always failed, recommend this book to them.
Type 2 diabetes is reversible with simple measures.
