Dr. Jason Fung – ‘A New Paradigm of Insulin Resistance’
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.

Thank you! Excellent video, very well-explained. Shared with my family. I am disabled and exercise was never going to get me where I want to be. I started eating a ketogenic diet with daily IF ( 16/8 – 18/6 2 meals a day) since March 14/17 and have already dropped 22 lbs. I am not diagnosed diabetic but I suspect I am insulin resistant and was headed down the path to T2D. I now realize I am going to be the “guinea pig” for going LCHF/keto for my family. Once they see with their own eyes that a disabled person can successfully get healthy and lose weight effortlessly, they won’t have any excuses! Love your videos!
Petra Sartor awesome,
Petra Sartor more power to you
Hey … you look like that guy …
How do you start the keto diet
Eat less than 20 grams of carbs a day. For more info, check out the FAQ on reddit.com/r/keto and post in there to get more information/help.
Dr. Jason Fung is awesome, love his lectures and podcasts. I wish more Doctors can be like him
He needs to be on these ridiculous talk shows instead of the crap they put on them
What is his podcast?
I am long term type 2 and have tried the intermittent fasting 16/8, 20/4, and 23/1) concept and I watched my blood sugar rise over 200 mg/dl in 24 hours; moreover, what I did not realize is that even though I was not eating and my body glucose levels were rising, is that blood sugars were rising from my fatty liver releasing stored glucose. I also did not realize that high triglyceride levels were merely transports of the stored glucose and fat in my liver to my organs and sub dermal tissue which is why even though I hike 3 -5 miles 3 or 4 days per week, I never could lose weight. I watched this video and had an epiphany, all I need to do is maintain IF long enough and not worry about rising blood sugar levels in the short term and my organs will eliminate my stored sugars… eventually! You rock Dr. Jason Fung. It is quite humbling to learn something so obvious all the while eating low carbohydrate high fat lifestyle (i.e. no starch) since January 2017. I eat my 7 – 10 cups raw veggies 5 days of the week and my blood sugars dropped from an average 250 mg/dl to an average 170 mg/dl, but rarely did I see anything under 150 mg/dl, especially when fasting… now I understand what the dawn phenomenon is and the underlying cause of rising blood glucose even when not eating and after exercising… my body is dumping stored sugar from my liver… Wow, I feel so ignorant that I did not realize this until tonight… Once again, thank you Dr. Jason Fung… going back to LCHF and IF as of tonight. For the record, I have been medicine free (e.g. including insulin) since January 2017.
Mammatus Pother congrats my friend. Your self explanation of the facts helped me understand better the whole paradigm. I am going into this same journey today. No more carbs for me. But how about fruits? I love fruits and living them behind hurts. 🤔😢☹️
Don’t blame yourself, blame the doctors who were ignorant or who wanted to profit from your illness or who didn’t care enough.
Good luck and don’t give up.
Koralblue, When it comes to fruit, for myself, I try to limit sweet fruit to berries (black, blue, raspberry, strawberry, gooseberry (kiwi)), and when it comes to non sweet fruit, I eat avocado, eggplant, bell pepper, lemon, and lime). I also try to limit net carbohydrate intake to <50 grams per day, including leafy greens. When I eat fruits as mentioned above, I exchange them and lower my green veggie intake to allow the fruits so I can maintain the <50 net carbohydrates.
NOTE: I also eat the majority of my veggies raw in either a salad or blended into a salad drink; when I blend the veggies, I add red hot buffalo sauce to minimize the green flavor along with either extra virgin olive oil or avocado oil and I mix in 1 or 2 tbsp of apple cider vinegar with each salad or blended salad. Hope this helps you on your journey. So far, my morning blood sugar levels are slowly lowering by a couple of numbers... not a huge change yet, but a change in the positive direction for myself and the really cool part is I have only been doing IF this time for 2 1/2 days!
I am using an 18 hour fast / 6 hour eating window IF plan at the moment due to schedule conflicts and a lack of food preparation time. Another note: Fiber is your friend in this situation, the more fiber I eat, the lower my numbers are in the morning. I also eat mostly vegetables with 4 ounce portions of meat when I eat meat and lots of cheese, coconut oil, avocado oil, and EVOO.
Also, I do not eat grains, starches, or sugars with the exception of sugar alcohols like Swerve and Erythritol which is rare and minimal.
TheCompleteGuitarist, thank you for taking the time to provide support and encouragement.
Mammatus Pother Thank you do much for that recommendation. I eat a lot of fruits but I am going to try to limit myself and focus on the healing berries more. Since I gave a lot of inflammation To my joints and muscles I have been eating pineapples. Thank you and wish the best in your endeavour to get healthy again.
This man has the potential of saving millions of lives, unlike the so-called nutrition specialists…
He deserve more recognition from the world.
well he has my recognition. the thing is, I have been on keto for 2 years and had very good results but have yet to convince anyone else to do it. Very tired of watching my friends suffering and dying from sugar and carb addiction.
absolutely. The Food authority in America and in Australia is a disgrace
@Simon T
Their business model is to sell treatments NOT cures !
This is so important lecture for all of us .. wish that my father new about this .Thank you so much.❤
I’m guessing the American Diabetes society hates him. Did you ever notice it’s not Anti-Diabetes…or Anti-Cancer associations. No, they’re just making huge salaries while NOT coming up with much of anything. I knew in my gut diabetes was reversible the minute they told me it wasn’t.
We need a paradigm shift in the entire medical industry. I had the hardest time understanding the concept of treating type 1 and type 2 diabetes with the same treatment during nursing school. I remember asking my instructor why we don’t have the patients utilize the extra insulin circulating in the body with exercise and low carb diet. Her reply was that patients won’t make lifestyle changes. Seeing my patients suffer from diabetes is incredibly sad. Amputation after amputation. Kidney failure. Dialysis. Infections. Sepsis. And the list goes on and on and on. Why do we treat the symptoms instead of the cause??? Don’t you think the cure would be in the CAUSE??? A symptom is your body’s way of telling you that something is not right. Why do we just medicate the symptom and ignore the root problem??? All docs wanna do is prescribe meds for a symptom meanwhile the patient has all kinds of side effects. So, pt gets more meds prescribed for the side effects. I’ve seen enough during my time as a nurse to believe most chronic diseases are diet based. From the toxic gmo’s to the lack of vital minerals and nutrients needed to keep our own body’s immune system healthy and functioning properly. Doctors come out of medical school with only the knowledge of how to treat patient with pharmaceutical drugs. No knowledge of nutrition. It’s so sad.
And doctors that have been doctors for many years know that most patients will not make lifestyle changes, its a fact. Ask 10 doctors if they gave 10 of their patients the option of free cure with cutting carbs or medications and no lifestyle change, what would more choose and stick with. I bet only 1 of them would change lifestyle and stick to it. Ever seen a cancer patient smoke through the hole in their neck? yep

Ricky Bowman – What a terrible attitude. Perhaps the patient should be given the knowledge & then they can choose to cure themselves or keep killing themselves slowly. Perhaps doctors should be made to recite their Hippocratic oath before seeing every patient? Don’t lie to them to keep them on drugs and make the doctors money, just because you think “they won’t change anyway”! That’s just hateful! Doctors that don’t tell people that it is *completely* possible to cure their underlying problem should feel ashamed and bear the burden of guilt and blame for every one of their patients that die from type 2 diabetes!
Totaly agreeded
doctors are drug promoters but for not cures
This doctor actually saved many lives……Thank you Dr. Fung
Mind blown, as a physician I humbled to know that T2D is curable. I try to explain that my patients. Some patients understand but many only want a quick fix, only because they are addicted to sugar. But I’ll keep on promoting intermittent fasting and low carb/low processed sugar diet.
Keyur Parikh You are a good doctor
Great. Spread the word. Diabetes will bankrupt our healthcare system in the near future. Thank you for your efforts.
maybe you could, as a requirement to see you, have new patients for free, spend 30 minutes listen to Dr. fung, hold classes once or twice a month, and have a Q&A to fit all your new patients and invite already established patients if they want to really get better. 🙂
Fasting IS the quick fix and most patients are absolutely willing to give it a try. There is too many doctors willing to believe that patients are lazy and unwilling to help themselves. Some are, but most work hard to stay off of medications and to not be sick. How do I know? Because weight watchers is an enormously (pun intended) successful enterprise. People starve themselves and track their food and give themselves points. They cram themselves into gyms and make resolutions to lose weight. They DO try. The problem has been the advice has made them more sick and enjoy life less. Give them a healthy, easy to do option like eat whole foods and intermittently fast. People WILL do that.
That’s the problem there all addicted to sugar And they choose to ignore it they lie about how much sugar they actually consume and think that medication is the answer so they can continue sadly they’re very wrong this is especially true when talking young people young.
Thank you Low Carb Down Under for hosting Dr. Fung. To me he’s a brilliant and compassionate “Renaissance Man”. I’ve lost 40 lbs. since I had my first introduction to him online about a year ago. I still have about 25 lbs. to go before I’m in the weight range for my height. Thank you Dr. Fung for getting me on the right path!
Excellent post! I hope all doctors are listening to Dr. Jason Fung, because this is the future of medicine and diabetes care!
Yeah but how to keep the weight maintained? Once you lose alot of weight due to fasting then theres no cure cause you have to eat.
@Gene Lariv Go high fat and ultra low carb and limited protein and you will get better. NO Grains or sugars and no milk.
I am on a LCHF diet now, bmi is 130, can I still do intermittent fasting? A1c was 12, need help
Like sure do yourself out of a job right? Lucky for us like almost none wants to do it. They will do almost anything else swallow any pill get bariatric surgery but diet? Even if their joints hurt all the time its like the veryverylast thing they will do. They wait for the word inoperable and the first heart pains.
seachangeau I wish the information about this way of eating had been in the mainstream 35 years ago, along with all the individuals that are now getting the word out. I would have done it in a heartbeat because my experience of it and the results I’m seeing are astounding. I am thankful for the internet and any doctor that is truly intent on getting us healthy instead of slapping a bandaid on a symptom that will only cause a need for anther bandaid versus getting to the root cause.
Dear Dr. Jason Fung, you are a real medical doctor. Thank you very much for sharing this important information about causes of type II diabetes and how to reverse it. I will follow your instructions.
This man is just brilliant – and brave. I bet the pharmaceuticals just love you for revealing this very helpful information. You are very kind.
Dr. Fung, I am 82 years old, type2 diabetes for 22 years, 226lbs and on 300units of insulin per day. Without wishing to suggest that I have controlled my diet perfectly, I have followed the prescribed regime pretty well on a daily basis and my experience has followed pretty accurately how you describe it. Both my weight and insulin intake have risen steadily of late to my great concern. Having watched a couple of your videos I was persuaded by your logic and decided to try to fast. For a week I have used the 16/8 fast and additionally I have stopped eating with my morning, afternoon and evening coffee breaks and stopped eating desert with my main meal. After 1 week my insulin dosage is down to 100 units per day and falling, my blood glucose reading has been fairly steady for 3 days at 60mmol/L and I have lost 3lbs in weight. Not only that, but I am confident that I can maintain this regime in the future. I have related eye problems and my sight has been deteriorating for a number of years. My question is, if I maintain what I am doing, will my eye problem regress. I do not expect it to do so but I hope it will not deteriorate as fast.
I must express my appreciation to you for explaining the true problems I have been experiencing.
You posted 4 years ago. Do hope you are doing well and that your maladies have reversed. #carnivoreCure #DrKenBerry

Dr Jason Fung is opening the medical world to the reality of curing type 2 diabetes.
Lets hope the medical world starts to listen and educate the present doctors and the student doctors how to help these patients.
Dr. Fung changed my live. I lost 30lbs in 3 months and I can’t remember the last time I felt this great. Thank you so much!
What was your fasting schedule?
Hey so curious what you did/schedule you implemented?
Now it’s time to build strong muscles to live a long healthy life, not just being skinny
A million thanks to Dr. Jason Fung, Dr. Eric Berg, and Dr. Ken Berry. Following the advice of these 3 doctors, I’m happy to say that my fatty liver has been reversed. I did IF with LCHF but not necessarily keto for almost a year now.
What is LCHF?
@Nailda Mulder low carb high fat
Also dr. Robert Lustig!
Dear Dr.Jason Fung,
Your zealous ministry to heal the sick is clearly evident from your presentation which was from your heart.
Thank you for your commitment and unselfish attitude that among the many I am also one that benefited from your mission.
I am 68 years old, have reversed my type 2 diabetes, normalized my blood pressure, lost 20 kg weight all in 6 months and am now full of energy and free from all medications.
What you propounded is clear logic and one need not be a rocket scientist to understand it.
Please keep up your good works, may God bless you and your family.
If there was a Nobel Prize for Common Sense , Dr. Fung deserves it !!
I love his simple, caring, encouraging way. As a result I have cured my diabetes with intermittent fasting. No longer need metformin and insulin and I feel so much better having lost so much weight and look forward to being healthy. It is so easy – just don’t eat. It saves time and money. What could be more simple? Animals do it when they aren’t feeling well. What a relief!
Well done.
Well done but what are you eating in your diet
Fabulous! As a nurse, I see the battle with diabetes/obesity. Patients need more education and to be willing to make life style changes. Who does the education? There is no time to spend with inpatients. This was an excellent presentation.
I would like to start a non profit where people would volunteer to go to doctor’s offices and stand outside with education sheets and free copies of the diabetes code.
@Velma West & give free basic exercise classes to teach people how to use their bodyweight & their kitchen sink or bed to get metabolically healthy, also improving gut microbiome!
My gosh, this video was posted in 2017…..and in 2021 there are countless persons who still believe the lie that type 2 diabetes is irreversible. I’m sharing all these videos because knowledge IS power.
And my (now former) endocrinologist is one of them…
