A book that should change the world: The Diabetes Code by Dr. Jason Fung


Best-selling author, intermittent-fasting advocate and Diet Doctor columnist Dr. Jason Fung just released a new and very important book – The Diabetes Code.

Globally, the number of people with diabetes mellitus has quadrupled in the past three decades. About 1 in 11 adults worldwide now have diabetes mellitus (90% of whom have type 2 diabetes) and it has become one of the most common causes of premature death and disability. While other diseases, like smallpox, AIDS and tuberculosis, are now pretty much under control, we have completely failed to do the same with the epidemic of type 2 diabetes.

Why? Have we fundamentally misunderstood what causes the disease and how to treat it?

Today, most doctors, dietitians, and even diabetes specialists consider type 2 diabetes to be a chronic and progressive disease – a life sentence with no possibility of parole. But the truth, as Dr. Fung reveals in this paradigm-shifting book, is that type 2 diabetes is reversible.

This is a great book. It’s powerful, yet simple to understand. Dr. Fung even starts with a short chapter summarizing what type 2 diabetes is and how to reverse it, the “quick start guide”. This is so simple that a child could understand the basic idea after just a few pages – but likely a lot of professors will not.

You’d probably need a very long education to not understand something that should be so obvious. The book’s message feels extremely obvious to me, in a good way. It’s simple to understand, entertaining even, and it makes so much sense that it’s not surprising that the recommended treatment works so well for so many people.

Again, the only shocking thing is that this book is so very controversial. It shouldn’t be, and I’m confident that it will not be in the future. Within a decade or two from now, the message of this book should hopefully be generally accepted everywhere.

This book could speed this process up. It could change the world and the dramatically increase the health of everyone with type 2 diabetes – close to half a billion people!

This is a book that should be read by every single person – doctors, nurses and other health care professionals – who treats people with diabetes. And I can’t recommend it highly enough to anyone who has type 2 diabetes, or knows someone who do.

    Dear Dr Fung, I have a question for my mom. She has started Keto and she has seen tremendous drop between 5.9-7.7 n her blood sugar reading. Somedays if she has taken something sweet or carbs (unintentionally) her reading will go as high as 9. 7. As she was always in the 12+ range before, does she still require insulin injection. Her check up with her physician will be another 3 months, any advice would be really appreciated.

    Hi Dr Fung, i am á type 2 diabetic female since 2001 and stopped my insuline and metformine during 14 days while fasting. I drank only water. My blood sugar level never dropped but was multiplied by 3 (average 3.4) so as my uric acid (123). I was dizzy, energy less and had hard time focusing after 6-7 days.I lost 10kg. That was the only encouraging part. Unfortunately i had to stop fasting fearing for my kidneys and á precoma as my doctor said. What happened? Hope you will help me understand. Thank you.

    All I can say is WOW!

    Before the book, I was averaging blood sugars of 150 in the morning and 250-300 at night. Was taking 20 units of regular and 60 of lantus. Fours days into this eating plan, I have stopped regular insulin, cut my lantus to 20units and now to the point that I am stopping it over the next week. My blood sugars responded by dropping to 105 in the morning and 120's at night. I am surprised by my desire for snacking not being an issue. I am not hungry!

    They are both written by Dr Fung, but are different. You can find more details on Amazon.
