Dr. Jason Fung - 'The Aetiology of Obesity'

Dr. Jason Fung completed medical school and internal medicine at the University of Toronto before finishing his nephrology fellowship at the University of California, Los Angeles at the Cedars-Sinai hospital.

He now has a practice in Ontario, Canada where he uses his Intensive Dietary Management program to help all sorts of patients, but especially those suffering from the two big epidemics of modern times: obesity and type 2 diabetes.

Dr. Fung uses innovative solutions to these problems, realising that conventional treatments are not that effective in helping people.

I have been trying Dr Fung's ideas for 5 weeks now (low carb low sugar / 20-4 Fasting). I am amazed by the effectiveness of Intermittent Fasting, not only have I lost 14 lbs but I was taking 136 units of insulin a day and I am now COMPLETELY OFF insulin and my blood sugars which averaged around 9.5 are now averaging 5.4. Dr Fung I applaud you !!! Thank you for this wonderful change in my life!!!

Dr Fung, you are a genius! I found your book a year ago and as a 73 yr old retired nurse, I followed intermittent fasting and LCHF. 50 lbs later, I do not have to die fat. Wish I could give you a hug! Keep on keeping on and I will try to inspire others! God Bless you!!!!

14 months ago, I watched this video and it completely changed my world. I was a personal trainer for about 5 years and what I was taught was all wrong. I feel terrible for giving my clients bad advise. I lost 32lbs within the first 3 months and I've hit my body set weight and keep the weight off. I feel good, healthy, high energy, good gut, and have been told that I haven't aged. Thank you Dr. Fung.

I started Intermittent Fasting, a whole food diet, low carbohydrates and low sugar 5 months ago: without feeling deprived I have lost 40 lbs.
I’m 67 years old and weigh what I did in high school. Thank you Dr. Fung!

Im feeling very emotional listening to this. I have eaten healthily, walked and exercised, try to stay active all day. I have felt hungry and eaten more than I intended, tried eating regularly to keep blood sugars level but in the last 3 weeks I have tried IF. Oh my goodness! Im not hungry all the time and I have lost weight. This seems to be the missing link in my conundrum. Thank you Dr Fung. Your explanation makes so much sense and to hear someone explain that we are not all gluttonous lazy slobs as so many people think we are just brings tears to my eyes.

I 3 personally know 3 people who followed his advice, lost weight, got off of metformin, and have really good blood work now. Dr. Fung is the man! Read his books (or listen to them). His series on youtube is excellent.

[roderickbashford]

A true inspiration 3 years ago i listen to this and followed his advice.
I went from 115 kilos to 86 kilos today.
Dr Fung is a Genius he uses logic and observation. If all doctors where like him humans would be a lot healthier.
Thank you Jason.

Every time I revisit this video I am filled with gratitude for this man who helped to reverse T2D, loose 50lbls in weight, reverse brain fog and memory lapses and improve my immune system. He is brilliant truth teller. I am surprised he has not been taken down.

I love the Obesity Code. Have lost 12 lbs in 3 weeks already (much more to go). What struck me is that I am back to what I always deep down knew was the way to lose weight: just don't eat. That's what I used to do, but then I began listening to all the mambo jumbo out there and kept gaining wait. Super easy and effective! I feel great!

[debbieheine]

Dr. Fung is the best!! His explanations are wonderful.

Thank you for your work! I am a RN and I am so sick of the obesity-causing chronic illnesses. Something must change! Intermittent fasting is the diet of our ancestors when food was not readily available in a refrigerator and we survived! You deserve all the rewards coming your way.

[waulau]

To me he is one of the Greatest doctor I ever seen. So helpful and so honest ! A very kind man. Thank you Dr Jason Fung.

[TheStancutler]

Dr Fung you have just explained the problem of obesity so well-thank you

[oscarpratyash]

Low carb, low fat, plant based diet, Intermittent fasting, fasting, unprocessed foods made me loose 40 pounds in 3 months.I have reversed my diabetes and fatty liver and I feel more energetic and healthy than ever.

[jimmckay]

I have been keto over 2.5 years and intermittent fasting about 5 days a week for 2 years. I lost 50 lbs., maintained my new healthy weight, and have not gained anything back. I actually have to force myself to eat some days because hunger is rarely an issue. On the SAD, I was getting hungry every day after 2 hours of not eating anything.
I am so happy for this new scientific information that has come forth. Thank God that Dr. Jason Fung freely gives this information to others to help them become healthier. It is a very unselfish act that shows how he truly believes in people becoming better for themselves.
