The Obesity Code - Reviewing underlying physiology of weight loss and how low carb diets and fasting can help. www.amazon.com/dp/1771641258?ref=exp_jasonfung_dp_vv_d
Dr. Fung, you likely greatly extended my life possibly even saved my life. 9 months ago, I had no idea what Diabetes truly was I was treating the symptoms and even though I thought I was doing well after two years of "treatment" I got my highest A1C ever 11.8. I was crushed I found your channel and you helped me understand insulin resistance and the tragic short comings of my Doctors and the knowledge the provided me. I began to treat my insulin resistance with a low carb high fat diet, intermittent fasting and some prolonged fasts . I was able to stop injecting myself with insulin almost immediately, within four months without medication my A1c was down to 6.8 and now I'm a 5.5. I have lost 90 lbs in 8 months and I feel like I am in control of my life again. Thank you for taking the time to explain this to the world. My wife and Children thank you
When will Dr Fung reach 1M subscribers? He is so underrated, will forever be thankful to him, I lost 50 lbs and has kept the weight for 2 yrs now. From prediabetic to normal, I’m feeling great and feel so light. Thank you Dr Fung!
If someone watches this and they still don't get it, chances are they never will. This is as simple as it gets. Thank you Doctor, you are such a blessing!
Jason Rocks!!! Before I learned from Jason, I was eating every 2 hours and was hungry all the time. I didn't know what was wrong. It was crazy. I was on the road to T2D. Today I'm in a much better place. Thanks!!! 👍🍻
My doctor told me to eat little and often! So I was more or less grazing all day and night. Now I eat twice a day and 7pm is my cut off time, I eat nothing till the next day. I am the first in my family to get type 2. When I was young all food was purchased daily and prepared from scratch. Our last meal was at 5pm and nothing till morning apart from bedtime cocoa.
Actually, no. Fung's interpretation of physiology and biochemistry is absolute trash. It's just that cutting out carbs and IF happens to produce a net energy deficit so people will lose weight, and thereby reverse health problems associated with being overweight. So It's great that people have lost weight due to his videos... but it's not for the primary reasons he's preaching. Anyone who has actually studied biochemistry and physiology will know the he's cherry picking information to push his narrative, which is to demonize carbs and sell his products. Take everything he says with a grain of salt. If people are actually interested in learning about Physiology and BioChemistry, pick up books... not listen to youtube as your primary source of information. If Keto and IF works for you, fantastic. Keep it up. But he is not providing accurate education on the subject of Physiology. There is NOTHING wrong with Carbs for the average person who doesn't have medical conditions relating to insulin resistance.
@@nickplaysmyteam8394 It's all relative. There is no One-Model-Fits-All. Someone with specific medical issues to insulin resistance would benefit from controlled intake of carbs. A bodybuilder/athlete or active person shouldn't have any issues with carbs when they're that active. An overweight person trying to lose weight would need to watch the amount of anything they eat, not just carbs, if the intention is to lose weight. A famished North Korean citizen who might have more access to cheap carb sources (like rice) won't need to watch what they eat, they just need to eat. There is no innate problem with carbs for a relatively healthy person, with no issues to insulin or any kind of other allergic reactions to specific carb sources. But just like Everything, just don't overdo it. You can die from drinking too much water, so it's all relative. And just to throw it out there, because there's so much misconception... Carbs by itself does not make a healthy person diabetic. There are other factors that contribute to Type 2 diabetes.
@@got_logic1320 I think ur completely missing the point. Dr. Fung isn't 'demonizing' anything. He's not claiming healthy active people will develop insulin resistance/Type II diabetes from carbohydrate consumption. He addresses how patients can reverse Type II diabetes naturally thru: 1. Elimination/reduction of excess sugars, high carbohydrate, processed n fast foods that elevate serum insulin levels leading to chronic insulin resistance 2. Intermittent fasting - one meal a day (OMAD) as a natural n safe way to use fat stores for energy, lowering serum insulin levels reversing chronic insulin resistance 3. Maintain a low carb diet higher in natural fats and proteins from whole unprocessed foods n exercise for healthy lifestyle The results speak for themselves. His years of clinical research, data, n physiological biochemical mechanism of insulin resistance is very sound - this coming from a Biochemist/Cell Biologist myself. Read his books and/or see some of his longer form presentations on his clinical research. He explains in clear detail the physiological pathways for obesity/insulin resistance and how to naturally reverse those pathologies.
When I hear a commercial for a diabetes drug with a catchy jingle that explains: "Because your pancreas can still make insulin, it just needs some help to make more..." I want to throw things at the TV.
Dr fung. I just wanted to thank you. I almost died a year ago from side effects of a diabetic medication. My a1c was around 13. I read your book recently and I am @,6.4 now. Thank you for all you do.

Dr Jason Fung's book " The Diabetic Code " changed my life. Explains so well how to reverse diabetes, transform and take back control of your health through lifestyle. I highly recommend. God bless you!
Yep! I read all his books The Diabetes Code, The Obesity Code, and The Cancer Code. Very informative, excellent books. I am not even overweight nor type 2 diabetic but I learned so much. Dr. Jason Fung and Dr. Sten Ekberg are my online doctors 😅 now.
Yes, Dr Sten Ekberg! Excellent truth teller & teacher. Also Dr Sanjay Gupta, York cardiology. Have learned so much, incredibly helpful information. Very thankful
Thank you Dr. Fung, my mother's HBA1C was 7.4 last May. After 3 months of stopping bread,drinking tea and low carb diet it goes down to 6.4. My youngest sister is 74kg last May now,Sept she is down to 63kg doing 20:4. For myself i lose 6kg from 77.5kg to 71.5kg doing 18:6.
@@salilp84 Is that measuring Glucose or Insulin? Usually these monitor Glucose and not Insulin. Seems like the product info for this says it monitors glucose.
Thank you Dr.Fung and everyone who advocates IF/TRF and low carb lifestyle. This is saving my life and my husband’s. 30 days and already lost 10lbs, no exercise and high carb. Now on my 2nd month, OMAD-2MAD, low carb to carnivore meals. Will check back here on my 60th day❤
I had initially lost 36 lbs this year (since Feb) doing a lot of exercise and also 18:6 IF with several OMAD days and low carb (def. not keto....more like Adkins as far as the protein and carb %). I eventually stopped losing weight. I'm thinking after a while my BMR slowed down....in fact I'm certain of it. I'm going to start eating breakfast again once in a while to mix things up and see if that helps. Curious if others have had this same issue.
@@keithzastrow Yes, I do 16:8 and "Atkins" style low carb. It took me about 8 months to lose 20 lbs, and I have not lost additional weight for about 2 months now. The only recommended variable I have not followed is resistance training. I have been resistant (pun intended) to it. I am going to try really hard to do more resistance training as we go into less "walking" friendly weather.
I don't want to be rude but average Chinese is more slim than you so this keto thing doesn't work for you and I suspect keto doesn't work long-term for anyone. You were normal, slim Chinese like 8 years ago I have seen older lectures so... just think about it, why almost whole Asia is eating rice, low fat and people here are slim ?
I'm a 4th grade teacher, it is crazy how many kids already have insulin resistance. I even see some kids with large bellies, dark necks, and moles on their necks. Me and one student are working today to have healthy habits
Past few years I've found out I'm pre diabetes and I did have a fatty liver. After learning on social media how to care for myself and now don't have a fatty liver & I'm now educating my 13 year old son. He's one of the few healthy looking kid's at his school. He drinks only water and has very little junk food.. I dont understand the school system that priorities other things that I won't name over kid's health. I know it's really up to the parents but obviously they're none the wiser as well..
I once was a class chaperone for a field trip for my Daughter’s elementary school. I saw this little girl (not overweight) that she was sitting next to pull out her lunch. Her lunch box contained ham and cheese on white bread, chips, a Devil Dog, the candy sticks that you dip in colored sugar and lastly Hawaiian Punch. I wondered to myself how much sugar was contained in just that one meal? That was just lunch. What do her parents feed her for breakfast, for an after school snack, for dinner, for dessert? How do any of these kids even have a chance of living a healthy life when their parents feed them nothing but processed junk daily?
Jason, what do you say to the medical practitioners who claim that insulin resistance is caused by too much fat in the liver and muscle cells, which have no more room to store glucose brought to the cells by insulin? These Drs call for a low fat, plant based diet. Please let me know if you agree or disagree with this theory and why? Thanks!
@Ludakris okay, thanks for your explanation. Are you a medical professional or just someone like me trying to find physiological balance. I used to be on a low fat, plant based diet and it worked to lower my blood sugar. But I felt very bloated and crappy most of the time. If I can eat high fat and eventually get my glucose levels down that way as well it would be a preferred way to do it.
Thanks Dr. Fung! Your book The Obesity code changed my life. I finally learned the science behind weight loss, not the gobbledegook that is parroted in women’s magazines and the mainstream media. I lost 30 pounds in 10 weeks while saving time and money and the never ending anxiety I felt around food is gone. I’m at my goal weight for the first time since college (over 20 years ago). I’m spreading the word to everyone I know. Thank you for the inspiration and knowledge. My only complaint is that now I need a whole new wardrobe! 😅
You are fantastic in your way to explain! Thank you ever so much! As I now focus on Hyperinsulemia I can not wait to start solving that. And I feel as if I am on the right side. Me and my body will do everything we can to lower insulin. Thank you and please continue!❤ I am learning so much! I now have hope thanks to you. I can do something. My doktor has mostly scared me because the blodsugar is slowly but consistent increasing. I can not thank you enough and I will tell friends to listen to you. 🌿🌷🌿
It's not rocket science. You just have to have self control and not fill your face with sugar, carbs, all processed foods and sugary drinks. Do some intermittent fasting for 24-26 hours once a week and some HIIT. The weight will literally fall off you.
I am so glad I stumbled onto one of your YT videos one evening about 4 months ago. Your message has changed my life. I am on my way to improving my metabolic health. TYVM!
good evening Dr Jason Fung, i have tried your fasting advice, and my lab result now is miraculous, 3 months ago may gluocose was traced and my HBA1C is 10, after one month of 16:8 and also tried also 3 days water fasting(once), and the remaining two months, sometimes i break my fasting time, but still after 3 months my lab result of HBA1C is 6.1 and my gluocose is clear, thank you Dr Jason Fung, may God bless you more
Dr Jason Fong you have spoken the truth and thanks God that you are not a lawyer or a politician . Never give up, keep striving for sharing learned knowledge to the people of this world 🌍🌎 to uplift and better health . For all the people. May the All Mighty God bless you. Thank you from Johannesburg South Africa 👍💕
I couldn't thank this doctor more. When all the texts claimed there are no "cure" for diabetics but high dises of insulin shots, his recommendation of intermittent fasting and low carb diet gave me a ray of hope. My vision was blurry, excessive sweating, hangry that never subsided, neuropathy in my hand and feet and degrading cognitive quality. By following intermittent fasting with no snacking and mild cardio, I could already witness the improvement with my TG going down, losing all the belly fat, my energy levels going up and my mid meal hunger going down. His theory on insulin and insulin resistance was an eye opener for me, and changed the way i eat. Adding little more effort like weight training and long fasting i managed to bring down my a1c from 11.9 to 5.5 in 3 months. My fasting too went down from 291 to 110s. Insulin levels too look fine. Looking forward to continue the effort bring the levels further down to 90s. If you're a newly diagnosed with t2 or have just got tired with the standard procedure care, do yourself some favour and listen to this man. Come out of High CarbHigh-Insulin-High Blood Glucose circle lf death. You will never be able to improve with drugs. Dietary carb restriction, mild excercise and fasting are the only tools you've got. Dr Fung, you have no idea how you're transforming lives of thousands. Thanks for all your suggestions.
Many thanks for enlightening with general, fundamental issues explaining important common problems! I knew what I.R. was, but I have not been aware, that it was a quite natural reaction of a body.
are you saying, democracy made your dad fat and diabetic, and communism cut it down and reverse diabetes? Well, fact says during 70s when people in China were poor and famine all around in Communist Country China, they lived longer and happily ever after or so. :) hahahaha
@@Oneworld1984 yes but that happens to everyone even non diabetics. He does not eat a lot of carbs mostly protein, fats and vegetables. This minimizes the blood sugar spike. It took a couple of months to see the results because his body has become more sensitive to insulin. It really works it just hard because of the sugar cravings but they go away eventually.
Dr, pl make one video on Indian people because India has more diabetic patients in the word. The staple food that is a meal plate consists of mainly rice and wheat with 25 % boiled vegetables in it.
I have been watching your videos and have been doing IF and keto for awhile with good benefit. Bloodwork improved, fatty liver gone, etc. for some reason though, today I decided to get a DQ blizzard ( never had one before), get the Oreo one with the fudge in the middle . As I’m eating this, you’re words of hyper insulin Emma are going through my head and you say are bodies aren’t stupid which is true but today, my mind was clearly stupid. I barely ate half of the blizzard my taste has changed, it was sickly sweet and now I have visions of glucose molecules going into my liver! I have Blizzard remorse. Tonight is not going to be fun with the sugar spike and crash. Lesson learned- shall carry on tomorrow back yo keto and IF.
While I like the fact that Jason promotes the benefits of fasting he did not answer the question his video asks. He says insulin resistance is caused by too much insulin. But what causes the persistent high levels of insulin? He states that when you infuse healthy people with high insulin they increase their insulin resistance. This does not prove much at all because a healthy person doesn’t need any extra insulin. The underlying problem is too much fat in the diet especially saturated fat. It’s called intramyocellular lipid toxicity. We eat too much fat which increases insulin resistance which increases the amount of insulin in the blood which increases fat storage which increases insulin resistance. Feel free to google this. When we eat loads of fat the fat is stored in the liver cells in excess and the muscle cells in excess. This decreases the effect of insulin on ushering glucose into the cells. When insulin is less effective glucose builds up in the blood. Carbs didn’t cause this. And lowering your carbs adds to the problem. Yes your sugar levels may decrease but you are substituting carbs for more fat which is increasing your insulin resistance. Its like hitting your knee every day with a hammer (fat) and saying the solution is to stop using your leg forever (carbs). Fix the problem which is the fat and you can eat all the carbs you want and your insulin levels will be minimized. Lower the fat in your diet and eliminate saturated fat and you will decrease your insulin resistance 100% of the time. Don’t take my word for it either, test it for yourself. If you’re type 2 eat 10% fat total for the whole day for 72 hours and you will see that your sugar will decrease significantly and you will still need less insulin or medication. Monitor closely so that your sugar doesn’t go too low. Do it with Md supervision. Read about Dr. Walter Kempner, Dr. John Mcdougall etc. Their patients get off their medications and no longer have diabetes and eat all the carbs they desire.
The old "Google it" so it must be true. LoL! Diabetes is a result of too much sugar in the blood which is caused by eating a diet high in carbs, sugar and processed foods eg Pizza, pies, pasts, panne (bread), potatoes, cakes, cookies, sugary drinks, alcohol, etc. How come people have been advised by numerous health providers in developed countries eg the US and Europe to eat a low fat diet, high carb, fresh veg and fruit, avoid meat diet for the last 30-40 years and we are now seeing a massive epidemic of huge fat obese diabetic slobs? Explain this? This is what you are basically advocating and is a scandal. Do you work for or have financial interests in big pharma as their solution is to prescribe anti-diabetes drugs such as Metformin for life?
Yes! I was going to say the same thing. Been studying this forever. Yeah, Kempner Rice Diet CURED insulin resistance on white rice, sugar and fruit of about 2000 calories a day. The before and after pictures are amazing. Only 4-5% protein and the rest carbs. You explained it very well.
Dr Fung is a genius on the subject and a true life saver... his videos helped me to reverse my heavy level T2D just in 3 months.... and off it (i.e.,; no medication) for over 2 years now... Bring HBA1c from 104 to mid 30s in 3 month... and ever since it varies between 28 to 37. Thank you Dr. Fung...
Hi Tom, I came across to Dr. Fung 1st time in my life on 1st of June 2020, after my HBA1C reached over 100 first time on 31st of May 2020 (104 to be exact). When my normal doctors in the UK told me that its heavy duty T2 now and it is only progressive from here... first we manage you via Metformin and if things got worsen you will be on Insulin. I was also 120 kgs weight at that point. Then I researched about T2 on internet and thank God I came across to Father on the subject on the very 1st day of internet research.... it was no other than the GREAT DR JASON FUNG saying in one of his videos that it is totally reversable condition... that even made my wife a laugh... I said to her o.k. at least let me try.... I started strict and disciplined Intermettent Fasting from 1st of June 2020. Started with 14 hours fast with 10 hours of eating window during 1st 10 days. No carb eating in 10 hours... and strictly no sugar and no soda or juices. Only whole fruit, any kind of meat (beef, chicken or lamb / mutton but no pork). A lot of salad with mix of vegetables. And 5km walking on daily basis (roughly taking me 1 hr in walk). After 10 days I increased it to 16 hr to 8 hrs. With 5km walk continues daily. Next 10 days (21 June to 30 June); 18 hr to 6 hr pattern. With 5km walk continue. 1st July to 15 July .... 20 Hr to 4 Hr pattern. With 5km walk continue. 16th July to 31st July back to 18hr to 6 hr window. In August it was alternative days of 18 to 6 hrs of fasting and OMAD (one meal a day... (i.e., 24 hrs Intermettent Fasting). In August 15 days of OMAD and remaining 15 days of 18 to 6. All 90 days kept walking 5km a day minimum... sometimes 6 to 7km. In all 90 days no sugar, no soda, no bread, no rice.... a lots of meat... a lots of stakes... a lots of salad... a lots of whole fruits... all kinds.... occasionally couple of dates for my sweet tooth. And on 1st of Sept when I tested my HBA1C it was 35. My GP in UK was on his toes as he couldn't believe it and started asking me what I have done.... you know what I said to him (in my heart).... Go idiot... park your old school approach and books which have thought you to tell your patients that it is a progressive decease and there is no long term cure. Go and listen to the GOD on the subject... the greatest of all... THE DR JASON FUNG.... and he will tell you that some medical books needs rewriting. If someone treats you with medication (tablets or injections)... to me that is not medicine (i.e. medical practice or knowleadge). However, if someone treats you and makes you perfectly healthy without giving you medication but by only making you understand the basic physiology of the body... NOW THAT IS MEDICINE.
@@hassanbilal1942 Thank you so much for taking the time to give us this chronology of how you saved your own life with the help of Dr. Jason Fung. I'm going to follow your schedule for fasting and exercise. You have inspired me.
30 is still very high. Keep trying to lower it further. Try to do the excise before the breaking fast and try to walk 1 hour. Your Docter was interested and was asking what you did. You should help him to learn, if he is willing to. You did the right thing to inform yourself and take responsibility for your body. Congratulations
Very strong logical argument. Bravo 👏 & unique and original thinking that is correctly laid out to make the case. Well done. Thank you for saving my life from living hell as I age into my early geriatric years, turning 52 soon. But I'll be turning 52 years younger then I was at 51, no joke. Doing taekwondo x3 yrs & won my first match. Joining my TKD school's sparring division. INCIDENTLY, this serves as my HIIT. I'm 3 years into this... Low carb - omnivore - with high plant food ( leafy greens and EVO) & aiming to get my ideal body wt of daily protein, 155 grams (tough to do) - Grocery store eater. Never going back to S.A.D. eating. Learning to eat only during the day light hours, circadian rhythm. Proper sleep too but I work nights, tough one. And zone 2 jogging. 🙌🙏🤜🤛❤️
Avoiding a diet of processed food high in carbs and sugar or indeed avoiding eating a lot of sugar in the first place whether added or naturally occurring as in fruit.
What causes this condition I got diagnosed at 27 I was completely normal weight then all off a sudden I became obese activity and diet the same out of nowhere I started tanning massive amounts of weight what is the causes ? And treatment
Not to be confused with reactive hyperinsulinemia that causes hypoglycemia. An interesting drug cause is oxcarbazepine increases trpv1 and TRPV1 at the small intestinal pancreatic interface causes insulin secretion that is hyperinsulinemia as it then leads to hypoglycemia.
I've given up smoking 13yrs ago, alcohol 18mths ago, now time to focus on carbs. Been Intermittent Fasting for 4yrs, love it, but have not experienced significant weight loss...now this last 6 months have put on 20lbs. It must be carbs...the more I try to lower my intake, the more I crave them. I'm about to give up....I feel broken.
Like Dr. Fung, I am a “why” person. I believe there is a reason for everything. I need to know the why. I also believe that what I know this moment could be completely wrong. To me, knowledge is based on the best factual information in my possession. Fifty years ago I tried to tell my doctor I was experiencing massive blood glucose excursions caused by hyper insulin secretion. He (tried to) told me there is no such thing, that type 2 diabetes only affects old people. Over the past few years I have connected most of the dots. But after reading The Diabetes Code, I finally have the answers I have long been seeking. Most important, Dr. Fung has given me HOPE. I am at a loss for words to thank Dr. Fung. In my view a Nobel Prize would not be enough.
Ive been doing intermittent fasting for a couple of months now bc I have insulin resistance and fatty liver. Now I'm pregnant. In a prev pregnancy I had gdm and managed with out meds (contrary to what Dr wanted) baby was fine. The dietitian is recomending the three meals, plus snacks. I feel this is too much. I've still been doing the fasting with a lunch at noon, snack later, and a dinner before 7. I workout 5x a week for 30 min or more. Can you make a video with advice for gdm pregnant moms with tips or advice. Thanks!
Hi Dr. Jason Fung! Hope yu r doing great. I benefited a lot from intermittent fasting fr the last few months. You hav enlightened me with this magical fasting method. My age s 31 and doing fasting really helps me but some other researchers and doctors are talking about varying fasting hours at various stages of menstrual cycle and Ovulution. So confused now..Pls can you do a detailed video on that ? To help us all through ur valuable knowledge.. pls do consider my obligation.
Low Fasting Insulin but higher fasting glucose. My Fasting Insulin is 3, and my fasting glucose is about 110. A1C is 6.3. Is this insulin resistance? My doc is perplexed. Can you help me understand this situation?
Thanks so much Dr. Fung!.., as always you are so very informative and your research is now saving my life as well as 1000s of others I'm sure. Can you explain why some people develop insulin resistance and others don't even if their diets are similar?
Dr Fung, can insulin resistance lead to (or contribute to) pathological calcification? Specifically, can IR lead to calcification in the kidneys? My mother's GFR number has decreased significantly this past year, and I wonder if there is an association with IR. Thanks.
I dont know anybody insuline resistant in my family or friends despite that they all eats typical polish food as grains and potatoes always with meat (pork or chicken) and some kind of sauce every day all life. Question is what is exess. All physical active no gym just physicall work or busy life.
thank you dr. jason fung, i followed your advise, i have done 16 and 24hrs intermitent fasting and proper diet and exercise did reverse my type 2 diabetis. thank you.
when you see that 1) you go to the conventional doctor and he fills you with medicines for everything. and you think that the integrative is going to help you and you spend a lot because 2) you go to the integrative (which charges in dollars, is not covered by any insurance, and does not take care of it because it is not a doctor,) it is to shoot yourself. The integrative doctor, like the conventional one, you have to look for it like a needle in a haystack, because most use the same formula, they put you on an elimination diet, they fill you with vitamins and natural medicines (which is not covered by insurance and you pay in dollars) but when you have any effect of these medications, or some symptom sends you to your conventional doctor???? what does that mean???? . In the end, study and be your own doctor, learn to listen to your body, because you know something???? none or few doctors (integrative or conventional) will listen to you and will be supportive of you.
I recommend that everyone in this thread read The Diabetes Code. It was THE game changer for me. THE diabetes ‘problem’ is insulin resistance caused by hyperinsulemia caused by consumption of sugar especially high fructose corn syrup and seed oils.
A better explanation would be to say that the cells are stuffed full......and more insulin is needed to force more of the abundant glucose into the cells.
The main driver is fructose, true fact. The reality is that insulin resistance is a survival mechanism, just like all biological functions are. If you eat fructose you will stimulate insulin resistance to help prioritize energy to prepare you for a famine. This is why we crave sugar so much. We are supposed to eat fructose in fruit in the fall so we can gain a few pounds, go into insulin resistance and prepare for the winter. Dr. Richard Johnson has proven this in his evolutionary description of fructose metabolism and why we gain fat. Just remember, we evolved survival mechanisms to help us survive starvation and a lack of food. One of the evolutionary roles of insulin resistance is is a way to help us gain fat to survive changing metabolic conditions, like a lack of food. Although there are other causes of insulin resistance, fructose is certainly the main driver. Most low carb people think just having high insulin causes insulin resistance. It may, but it's not nearly as much of a natural driver as fructose is. Check out Dr Johnson's work if you really want to understand insulin resistance, metabolic syndrome, diabetes and obesity from a scientific, evolutionary point of view. Dr. Johnson is right.
What utter nonsense you have written. Did you read this on the internet and now copy and paste it everywhere you can? Some of what you have copied and pasted is correct but a lot isn't. Fructose can only be metabolised and stored in the liver unlike other sugars such as glucose and sucrose which can be metabolised within body cells. Insulin resistance is NOT a survival mechanism. It is as a result of persistently high blood sugar levels and the body no longer being able to regulate it through normal insulin production. It is nonsense to write that we are supposed to eat fructose in fruit in the fall so we can gain a few pounds. Fructose is metabolised and stored in the liver hence people get NAFLD or cirrhosis of their livers. Please provide the source of your DR Johnson's research that you say has PROVEN his evolutionary description of fructose metabolism and why we gain fat. Which scientific or medial journal was it published in? Your are trying to pass off untested and unsubstantiated opinion as fact. I don't think you even watched this video as you clearly haven't understood what Dr F was saying. Insulin resistance is at a cellular level where the cell can no longer except any more sugar as it is FULL. Insulin is the hormone that facilitates cells accepting sugar only it no longer as any affect. This is insulin resistance. The cell is resistant to insulin. Enter drugs such as Metformin which make the cell accept more and more sugar as the dose is increased. The cause of a high insulin level is consuming too many carbs and too much sugar. End of. You really haven't grasped this have you? Do you have ANY biological, biochemical education training or qualifications? You just seem to have found something on the internet that fits with your agenda and now you copy and past it everywhere you can. Nutz.
A simplified explanation, but it is true. There are mechanisms behind this and the simple fact is that the cells are overloaded with stored glucose by the time insulin is high. The Randle Cycle is also involved. The net result is just as Jason says. You don't really need the details. Just cut the glucose, fast and empty those fat cells.
This is outright medical desinformation. There is a large body of evidence demonstrating that insulin resistance is not caused by physiological hyperinsulinemia but by increased amounts of adipose tissue, which causes the release of inflammatory factors (adipokines) and free fatty acids. These two factors mess with the function of insulin receptors on body cells. Yes, under certain pathological or experimental conditions with continuous high insulin levels, insulin resistance also occurs. We see this for example in insulinomas and when insulin is continuously infused over a period of at least several hours. However insulin resistance induced this way is transient, meaning it reverses the very moment the iv drip or the tumor is removed. In addition, in this video Jason Fung chooses to ignore a large pile of randomized controlled trials in humans clearly demonstrating that the amount and type of carbohydrates in a diet has no discernible effect whatsoever on metabolic status. If you control for calories that is. The bottom line is that conditions related to insulin resistance such as NIDDM and metabolic syndrome cannot be reversed by manipulating the amount carbs consumed. These conditions can however be reversed by creating an energy deficit. Yes good old CICO. Don't let anybody fool you otherwise.
Yes! Also there have been several peer reviewed randomized controlled studies that fasting is no more beneficial than calorie restriction for health and weight loss!
@@Hat65 You are correct. Btw, I am practicing IF in my weight loss journey because I like it and it helps me to maintain my caloric deficit. It's a tool, not a gospel.
Ok, there is an idea that high insulin causes insulin resistance. There may be some truth to that, but I can confidently tell you that it is not the main driver of insulin resistance, metabolic syndrome, obesity or diabetes. How do I know that? Simple, because of history. If high insulin was the primary cause of insulin resistance, then every society that ate primarily starches like the Japanese, Tukisientans, Central Americans, South East Asians would have all be suffering from staggering amounts of diabetes. We know this is not the case because many farming societies have been eating rice, bread, potatoes in huge amounts for thousands of years without getting insulin resistance, diabetes or even struggling with obesity. This also disproves the idea pushed by Bart Kay and others that the Randle Cycle is causing metabolic disease too. If just high insulin caused disease, then diabetes would have most likely been more rampant. I have found that the real cause of disease is fructose consumption. When you add fructose to a society's diet, diabetes becomes a huge factor. None of the ancient societies started getting sick until they added sugar to their diets. They were perfectly healthy on carbs and starches until they started eating sugar, more specifically fructose. Glucose and fructose are not metabolically the same. They are metabolized differently, and have different metabolic effects of the body. The reason nobody seems to understand this logic is because they are looking at disease from the wrong perspective. They are just looking at the science without regard to evolution. Since us humans evolved, we need to not just use science to attempt to explain what we should eat and do to stay healthy, we need to use science to figure out how we evolved. All animals evolved, and evolution always tells the truth. Fructose is our evolutionary survival nutrient, but since we eat way too much, it's making us sick.
@@dianepereira1860 This seems to be what CJB is saying although they do seem quite confused. They seem to be under the impression they are more informed than Dr Fung on insulin resistance, they know something he doesn't and are trying to educate him. LoL.
@@dianepereira1860 No, I'm certainly not saying that. I think insulin resistance has many causes. I believe however fructose causes the most insulin resistance in humans worldwide.

Hi is it true for T1D also? More insulin more resistance?
Dr. Fung, you likely greatly extended my life possibly even saved my life. 9 months ago, I had no idea what Diabetes truly was I was treating the symptoms and even though I thought I was doing well after two years of "treatment" I got my highest A1C ever 11.8. I was crushed I found your channel and you helped me understand insulin resistance and the tragic short comings of my Doctors and the knowledge the provided me. I began to treat my insulin resistance with a low carb high fat diet, intermittent fasting and some prolonged fasts . I was able to stop injecting myself with insulin almost immediately, within four months without medication my A1c was down to 6.8 and now I'm a 5.5. I have lost 90 lbs in 8 months and I feel like I am in control of my life again. Thank you for taking the time to explain this to the world. My wife and Children thank you
Dr. Fung should get a humanitarian award, at the least.
He is a Doctor Without Borders. He is a Hero! ❤️
Well said!☝️
When will Dr Fung reach 1M subscribers? He is so underrated, will forever be thankful to him, I lost 50 lbs and has kept the weight for 2 yrs now. From prediabetic to normal, I’m feeling great and feel so light. Thank you Dr Fung!
He did now
Yup
I listened to him everyday and share to all my friends. Thank you Lord for his knowledge and unselfishness 🙏🏽🙏🏽🙏🏽
He makes it so blindlingly clear.😊
If someone watches this and they still don't get it, chances are they never will. This is as simple as it gets. Thank you Doctor, you are such a blessing!
Most General Practitioners don't get it. Sadly.
At last!! An explanation that I can understand and that makes complete sense. Thank you so much!
Jason Rocks!!! Before I learned from Jason, I was eating every 2 hours and was hungry all the time. I didn't know what was wrong. It was crazy. I was on the road to T2D. Today I'm in a much better place. Thanks!!! 👍🍻
Awesome man! The idea of eating 6 meals a day to stay healthy and keep metabolism high sounds ludicrous after watching dr fung
My doctor told me to eat little and often! So I was more or less grazing all day and night. Now I eat twice a day and 7pm is my cut off time, I eat nothing till the next day. I am the first in my family to get type 2. When I was young all food was purchased daily and prepared from scratch. Our last meal was at 5pm and nothing till morning apart from bedtime cocoa.
Dr Fung continues to inform the public how to improve their health by understanding basic physiology.
Actually, no. Fung's interpretation of physiology and biochemistry is absolute trash. It's just that cutting out carbs and IF happens to produce a net energy deficit so people will lose weight, and thereby reverse health problems associated with being overweight. So It's great that people have lost weight due to his videos... but it's not for the primary reasons he's preaching. Anyone who has actually studied biochemistry and physiology will know the he's cherry picking information to push his narrative, which is to demonize carbs and sell his products. Take everything he says with a grain of salt. If people are actually interested in learning about Physiology and BioChemistry, pick up books... not listen to youtube as your primary source of information.
If Keto and IF works for you, fantastic. Keep it up. But he is not providing accurate education on the subject of Physiology. There is NOTHING wrong with Carbs for the average person who doesn't have medical conditions relating to insulin resistance.
@@got_logic1320 Ok bro, have fun staying fat 😂👌
@@got_logic1320 Yeah it's just about too many carbs per day. Right?
@@nickplaysmyteam8394 It's all relative. There is no One-Model-Fits-All. Someone with specific medical issues to insulin resistance would benefit from controlled intake of carbs.
A bodybuilder/athlete or active person shouldn't have any issues with carbs when they're that active. An overweight person trying to lose weight would need to watch the amount of anything they eat, not just carbs, if the intention is to lose weight. A famished North Korean citizen who might have more access to cheap carb sources (like rice) won't need to watch what they eat, they just need to eat.
There is no innate problem with carbs for a relatively healthy person, with no issues to insulin or any kind of other allergic reactions to specific carb sources. But just like Everything, just don't overdo it. You can die from drinking too much water, so it's all relative.
And just to throw it out there, because there's so much misconception... Carbs by itself does not make a healthy person diabetic. There are other factors that contribute to Type 2 diabetes.
@@got_logic1320 I think ur completely missing the point. Dr. Fung isn't 'demonizing' anything. He's not claiming healthy active people will develop insulin resistance/Type II diabetes from carbohydrate consumption. He addresses how patients can reverse Type II diabetes naturally thru:
1. Elimination/reduction of excess sugars, high carbohydrate, processed n fast foods that elevate serum insulin levels leading to chronic insulin resistance
2. Intermittent fasting - one meal a day (OMAD) as a natural n safe way to use fat stores for energy, lowering serum insulin levels reversing chronic insulin resistance
3. Maintain a low carb diet higher in natural fats and proteins from whole unprocessed foods n exercise for healthy lifestyle
The results speak for themselves. His years of clinical research, data, n physiological biochemical mechanism of insulin resistance is very sound - this coming from a Biochemist/Cell Biologist myself. Read his books and/or see some of his longer form presentations on his clinical research. He explains in clear detail the physiological pathways for obesity/insulin resistance and how to naturally reverse those pathologies.
When I hear a commercial for a diabetes drug with a catchy jingle that explains: "Because your pancreas can still make insulin, it just needs some help to make more..." I want to throw things at the TV.
Dr fung. I just wanted to thank you. I almost died a year ago from side effects of a diabetic medication. My a1c was around 13. I read your book recently and I am @,6.4 now. Thank you for all you do.

Yep! I read all his books The Diabetes Code, The Obesity Code, and The Cancer Code. Very informative, excellent books. I am not even overweight nor type 2 diabetic but I learned so much. Dr. Jason Fung and Dr. Sten Ekberg are my online doctors 😅 now.
Those are two of my favorite doctors, too. Also, Dr. Ben Bikman “Why we get sick.”
The truth is spreading.❤️
Yes, Dr Sten Ekberg! Excellent truth teller & teacher. Also Dr Sanjay Gupta, York cardiology. Have learned so much, incredibly helpful information. Very thankful
Thank you Dr. Fung, my mother's HBA1C was 7.4 last May. After 3 months of stopping bread,drinking tea and low carb diet it goes down to 6.4. My youngest sister is 74kg last May now,Sept she is down to 63kg doing 20:4. For myself i lose 6kg from 77.5kg to 71.5kg doing 18:6.

Thank you Dr.Fung and everyone who advocates IF/TRF and low carb lifestyle. This is saving my life and my husband’s. 30 days and already lost 10lbs, no exercise and high carb. Now on my 2nd month, OMAD-2MAD, low carb to carnivore meals. Will check back here on my 60th day❤
I had initially lost 36 lbs this year (since Feb) doing a lot of exercise and also 18:6 IF with several OMAD days and low carb (def. not keto....more like Adkins as far as the protein and carb %). I eventually stopped losing weight. I'm thinking after a while my BMR slowed down....in fact I'm certain of it. I'm going to start eating breakfast again once in a while to mix things up and see if that helps. Curious if others have had this same issue.
@@keithzastrow Yes, I do 16:8 and "Atkins" style low carb. It took me about 8 months to lose 20 lbs, and I have not lost additional weight for about 2 months now. The only recommended variable I have not followed is resistance training. I have been resistant (pun intended) to it. I am going to try really hard to do more resistance training as we go into less "walking" friendly weather.
I don't want to be rude but average Chinese is more slim than you so this keto thing doesn't work for you and I suspect keto doesn't work long-term for anyone. You were normal, slim Chinese like 8 years ago I have seen older lectures so... just think about it, why almost whole Asia is eating rice, low fat and people here are slim ?
because they don't have insulin resistance. use your brain
@@Lady.Luck. Take your own advice.
Wow thank u Doc
Now back to fasting and early walk
And learn with Dr Jason.
I'm a 4th grade teacher, it is crazy how many kids already have insulin resistance. I even see some kids with large bellies, dark necks, and moles on their necks. Me and one student are working today to have healthy habits
Past few years I've found out I'm pre diabetes and I did have a fatty liver. After learning on social media how to care for myself and now don't have a fatty liver & I'm now educating my 13 year old son. He's one of the few healthy looking kid's at his school. He drinks only water and has very little junk food.. I dont understand the school system that priorities other things that I won't name over kid's health. I know it's really up to the parents but obviously they're none the wiser as well..
I once was a class chaperone for a field trip for my Daughter’s elementary school. I saw this little girl (not overweight) that she was sitting next to pull out her lunch. Her lunch box contained ham and cheese on white bread, chips, a Devil Dog, the candy sticks that you dip in colored sugar and lastly Hawaiian Punch. I wondered to myself how much sugar was contained in just that one meal? That was just lunch. What do her parents feed her for breakfast, for an after school snack, for dinner, for dessert? How do any of these kids even have a chance of living a healthy life when their parents feed them nothing but processed junk daily?
Jason, what do you say to the medical practitioners who claim that insulin resistance is caused by too much fat in the liver and muscle cells, which have no more room to store glucose brought to the cells by insulin? These Drs call for a low fat, plant based diet. Please let me know if you agree or disagree with this theory and why? Thanks!
@Ludakris okay, thanks for your explanation. Are you a medical professional or just someone like me trying to find physiological balance. I used to be on a low fat, plant based diet and it worked to lower my blood sugar. But I felt very bloated and crappy most of the time. If I can eat high fat and eventually get my glucose levels down that way as well it would be a preferred way to do it.
@Ludakris okay, thanks for your thoughts.
Thank you Dr. Fung! I keep sharing you to most of my friends. You don’t know how many people you helped! You are brilliant! Again thank you doc! 🙏
Loved this! Can you please speak on how insulin resistance increases androgens in women? Like, the process? Thanks!
Love Dr. Jason Fung. I knocked out Diabetes and lost weight because of his passion for educating patients. My hero.
Thanks Dr. Fung! Your book The Obesity code changed my life. I finally learned the science behind weight loss, not the gobbledegook that is parroted in women’s magazines and the mainstream media.
I lost 30 pounds in 10 weeks while saving time and money and the never ending anxiety I felt around food is gone. I’m at my goal weight for the first time since college (over 20 years ago).
I’m spreading the word to everyone I know. Thank you for the inspiration and knowledge.
My only complaint is that now I need a whole new wardrobe! 😅
What a wonderful problem to have :)
You are fantastic in your way to explain! Thank you ever so much! As I now focus on Hyperinsulemia I can not wait to start solving that. And I feel as if I am on the right side. Me and my body will do everything we can to lower insulin.
Thank you and please continue!❤ I am learning so much! I now have hope thanks to you. I can do something. My doktor has mostly scared me because the blodsugar is slowly but consistent increasing. I can not thank you enough and I will tell friends to listen to you. 🌿🌷🌿
It's not rocket science. You just have to have self control and not fill your face with sugar, carbs, all processed foods and sugary drinks. Do some intermittent fasting for 24-26 hours once a week and some HIIT. The weight will literally fall off you.
Hi Dr.Fung thank you so much for this information
I am so glad I stumbled onto one of your YT videos one evening about 4 months ago. Your message has changed my life. I am on my way to improving my metabolic health. TYVM!
Hello Angelina
Thank you for breaking this down in a way that makes sense to me as a non medical proffesional.
good evening Dr Jason Fung, i have tried your fasting advice, and my lab result now is miraculous, 3 months ago may gluocose was traced and my HBA1C is 10, after one month of 16:8 and also tried also 3 days water fasting(once), and the remaining two months, sometimes i break my fasting time, but still after 3 months my lab result of HBA1C is 6.1 and my gluocose is clear, thank you Dr Jason Fung, may God bless you more
Dr Jason Fong you have spoken the truth and thanks God that you are not a lawyer or a politician . Never give up, keep striving for sharing learned knowledge to the people of this world 🌍🌎 to uplift and better health . For all the people. May the All Mighty God bless you. Thank you from Johannesburg South Africa 👍💕
I couldn't thank this doctor more. When all the texts claimed there are no "cure" for diabetics but high dises of insulin shots, his recommendation of intermittent fasting and low carb diet gave me a ray of hope. My vision was blurry, excessive sweating, hangry that never subsided, neuropathy in my hand and feet and degrading cognitive quality.
By following intermittent fasting with no snacking and mild cardio, I could already witness the improvement with my TG going down, losing all the belly fat, my energy levels going up and my mid meal hunger going down. His theory on insulin and insulin resistance was an eye opener for me, and changed the way i eat.
Adding little more effort like weight training and long fasting i managed to bring down my a1c from 11.9 to 5.5 in 3 months. My fasting too went down from 291 to 110s. Insulin levels too look fine. Looking forward to continue the effort bring the levels further down to 90s.
If you're a newly diagnosed with t2 or have just got tired with the standard procedure care, do yourself some favour and listen to this man. Come out of High CarbHigh-Insulin-High Blood Glucose circle lf death. You will never be able to improve with drugs. Dietary carb restriction, mild excercise and fasting are the only tools you've got.
Dr Fung, you have no idea how you're transforming lives of thousands. Thanks for all your suggestions.
I’m sorry to reply to such an old post. But did your neuropathy improve as well?
Happy Sunday, Dr. Fung. Stay happy , healthy, wealthy and wise 🤍😊
Hello Maricel
Can you help me with a diet plan to lower A1C. I'm desperate my A1 C is 7 and I don't want to do medicine
His books are fantastic read two of them 👍👍
Many thanks for enlightening with general, fundamental issues explaining important common problems! I knew what I.R. was, but I have not been aware, that it was a quite natural reaction of a body.
What a clear explanation! You should be awarded a general semantics prize. (Cf Korzybski)
My dad has almost completely reversed his diabetes. Thank you
Doesn't the sugar spike when he eats after long fasting ??
are you saying, democracy made your dad fat and diabetic, and communism cut it down and reverse diabetes? Well, fact says during 70s when people in China were poor and famine all around in Communist Country China, they lived longer and happily ever after or so. :) hahahaha
@@Oneworld1984 yes but that happens to everyone even non diabetics. He does not eat a lot of carbs mostly protein, fats and vegetables. This minimizes the blood sugar spike. It took a couple of months to see the results because his body has become more sensitive to insulin. It really works it just hard because of the sugar cravings but they go away eventually.
@@104silvae thank you
Dr, pl make one video on Indian people because India has more diabetic patients in the word. The staple food that is a meal plate consists of mainly rice and wheat with 25 % boiled vegetables in it.
I have been watching your videos and have been doing IF and keto for awhile with good benefit. Bloodwork improved, fatty liver gone, etc. for some reason though, today I decided to get a DQ blizzard ( never had one before), get the Oreo one with the fudge in the middle . As I’m eating this, you’re words of hyper insulin Emma are going through my head and you say are bodies aren’t stupid which is true but today, my mind was clearly stupid. I barely ate half of the blizzard my taste has changed, it was sickly sweet and now I have visions of glucose molecules going into my liver! I have Blizzard remorse. Tonight is not going to be fun with the sugar spike and crash. Lesson learned- shall carry on tomorrow back yo keto and IF.
☺️ Time for a 48 hr. fast ...
Did IF and KETO completely cure or just partially cure your Diabetes and Insulin Resistance ?
While I like the fact that Jason promotes the benefits of fasting he did not answer the question his video asks. He says insulin resistance is caused by too much insulin. But what causes the persistent high levels of insulin? He states that when you infuse healthy people with high insulin they increase their insulin resistance. This does not prove much at all because a healthy person doesn’t need any extra insulin. The underlying problem is too much fat in the diet especially saturated fat. It’s called intramyocellular lipid toxicity. We eat too much fat which increases insulin resistance which increases the amount of insulin in the blood which increases fat storage which increases insulin resistance. Feel free to google this. When we eat loads of fat the fat is stored in the liver cells in excess and the muscle cells in excess. This decreases the effect of insulin on ushering glucose into the cells. When insulin is less effective glucose builds up in the blood. Carbs didn’t cause this. And lowering your carbs adds to the problem. Yes your sugar levels may decrease but you are substituting carbs for more fat which is increasing your insulin resistance. Its like hitting your knee every day with a hammer (fat) and saying the solution is to stop using your leg forever (carbs). Fix the problem which is the fat
and you can eat all the carbs you want and your insulin levels will be minimized. Lower the fat in your diet and eliminate saturated fat and you will decrease your
insulin resistance 100% of the time. Don’t take my word for it either, test it for yourself. If you’re type 2 eat 10% fat total for the whole day for 72 hours and you will
see that your sugar will decrease significantly and you will still need less insulin or medication. Monitor closely so that your sugar doesn’t go too low. Do it with Md supervision. Read about Dr. Walter Kempner, Dr. John Mcdougall etc. Their patients get off their medications and no longer have diabetes and eat all the carbs they desire.
The low carb insulin hypothesis has been debunked several times by many sources lol.
The old "Google it" so it must be true. LoL! Diabetes is a result of too much sugar in the blood which is caused by eating a diet high in carbs, sugar and processed foods eg Pizza, pies, pasts, panne (bread), potatoes, cakes, cookies, sugary drinks, alcohol, etc.
How come people have been advised by numerous health providers in developed countries eg the US and Europe to eat a low fat diet, high carb, fresh veg and fruit, avoid meat diet for the last 30-40 years and we are now seeing a massive epidemic of huge fat obese diabetic slobs? Explain this? This is what you are basically advocating and is a scandal. Do you work for or have financial interests in big pharma as their solution is to prescribe anti-diabetes drugs such as Metformin for life?
Yes! I was going to say the same thing. Been studying this forever. Yeah, Kempner Rice Diet CURED insulin resistance on white rice, sugar and fruit of about 2000 calories a day. The before and after pictures are amazing. Only 4-5% protein and the rest carbs. You explained it very well.
Dr Fung is a genius on the subject and a true life saver... his videos helped me to reverse my heavy level T2D just in 3 months.... and off it (i.e.,; no medication) for over 2 years now...
Bring HBA1c from 104 to mid 30s in 3 month... and ever since it varies between 28 to 37.
Thank you Dr. Fung...
Would you mind sharing specifically how you did that? I would appreciate your story because I am struggling with this. Thank you.
Hi Tom,
I came across to Dr. Fung 1st time in my life on 1st of June 2020, after my HBA1C reached over 100 first time on 31st of May 2020 (104 to be exact). When my normal doctors in the UK told me that its heavy duty T2 now and it is only progressive from here... first we manage you via Metformin and if things got worsen you will be on Insulin. I was also 120 kgs weight at that point.
Then I researched about T2 on internet and thank God I came across to Father on the subject on the very 1st day of internet research.... it was no other than the GREAT DR JASON FUNG saying in one of his videos that it is totally reversable condition... that even made my wife a laugh... I said to her o.k. at least let me try....
I started strict and disciplined Intermettent Fasting from 1st of June 2020.
Started with 14 hours fast with 10 hours of eating window during 1st 10 days.
No carb eating in 10 hours... and strictly no sugar and no soda or juices.
Only whole fruit, any kind of meat (beef, chicken or lamb / mutton but no pork).
A lot of salad with mix of vegetables. And 5km walking on daily basis (roughly taking me 1 hr in walk).
After 10 days I increased it to 16 hr to 8 hrs. With 5km walk continues daily.
Next 10 days (21 June to 30 June); 18 hr to 6 hr pattern. With 5km walk continue.
1st July to 15 July .... 20 Hr to 4 Hr pattern. With 5km walk continue.
16th July to 31st July back to 18hr to 6 hr window.
In August it was alternative days of 18 to 6 hrs of fasting and OMAD (one meal a day... (i.e., 24 hrs Intermettent Fasting).
In August 15 days of OMAD and remaining 15 days of 18 to 6.
All 90 days kept walking 5km a day minimum... sometimes 6 to 7km.
In all 90 days no sugar, no soda, no bread, no rice.... a lots of meat... a lots of stakes... a lots of salad... a lots of whole fruits... all kinds.... occasionally couple of dates for my sweet tooth.
And on 1st of Sept when I tested my HBA1C it was 35.
My GP in UK was on his toes as he couldn't believe it and started asking me what I have done.... you know what I said to him (in my heart)....
Go idiot... park your old school approach and books which have thought you to tell your patients that it is a progressive decease and there is no long term cure.
Go and listen to the GOD on the subject... the greatest of all... THE DR JASON FUNG.... and he will tell you that some medical books needs rewriting.
If someone treats you with medication (tablets or injections)... to me that is not medicine (i.e. medical practice or knowleadge).
However, if someone treats you and makes you perfectly healthy without giving you medication but by only making you understand the basic physiology of the body... NOW THAT IS MEDICINE.

I’m living a very different life since discovering Dr. Fung’s videos in 2019.
Wow new camera nice quality
Thank you so much! I learn with each of your videos!❤
Fantastic explanation, concise, and easy to understand.
Can fasting in any way cause Insulin resistance ? Pancreatic cancer is a scary thing, would be interested in what keeps the Pancreas healthy.
Avoiding a diet of processed food high in carbs and sugar or indeed avoiding eating a lot of sugar in the first place whether added or naturally occurring as in fruit.
If this is true then why do doctors Prescribe more insulin to type 2 diabetics?
Insulin aren't given to type 2 , it's mainly for type 1
What causes this condition I got diagnosed at 27 I was completely normal weight then all off a sudden I became obese activity and diet the same out of nowhere I started tanning massive amounts of weight what is the causes ? And treatment
Thank you for sharing your knowledge, I am finally maintaining a healthy weight thanks to your books and videos.
I have insulin resistance and pcos
Not to be confused with reactive hyperinsulinemia that causes hypoglycemia.
An interesting drug cause is oxcarbazepine increases trpv1 and TRPV1 at the small intestinal pancreatic interface causes insulin secretion that is hyperinsulinemia as it then leads to hypoglycemia.
I've given up smoking 13yrs ago, alcohol 18mths ago, now time to focus on carbs. Been Intermittent Fasting for 4yrs, love it, but have not experienced significant weight loss...now this last 6 months have put on 20lbs. It must be carbs...the more I try to lower my intake, the more I crave them. I'm about to give up....I feel broken.
Awesome!
Always very interesting to watch!!
✌🏼😎👍🏼
Thank you. Framing it this way makes it even more understandable. With all the voices out there, I appreciate the clarity of your info
Like Dr. Fung, I am a “why” person. I believe there is a reason for everything. I need to know the why. I also believe that what I know this moment could be completely wrong. To me, knowledge is based on the best factual information in my possession. Fifty years ago I tried to tell my doctor I was experiencing massive blood glucose excursions caused by hyper insulin secretion. He (tried to) told me there is no such thing, that type 2 diabetes only affects old people. Over the past few years I have connected most of the dots. But after reading The Diabetes Code, I finally have the answers I have long been seeking. Most important, Dr. Fung has given me HOPE. I am at a loss for words to thank Dr. Fung. In my view a Nobel Prize would not be enough.
Me too. He changed my life completely. After seeing his videos and reading his book obesity code.
Ive been doing intermittent fasting for a couple of months now bc I have insulin resistance and fatty liver. Now I'm pregnant. In a prev pregnancy I had gdm and managed with out meds (contrary to what Dr wanted) baby was fine. The dietitian is recomending the three meals, plus snacks. I feel this is too much. I've still been doing the fasting with a lunch at noon, snack later, and a dinner before 7. I workout 5x a week for 30 min or more. Can you make a video with advice for gdm pregnant moms with tips or advice. Thanks!
thank you for excellent explanation ! had a hard time understanding insulin resistance
Me too 😮

Thank you for all you do. A favor please. Can you address the potential kidney damage due to prolonged or sensitive NSAID use?
Hi Dr. Jason Fung! Hope yu r doing great. I benefited a lot from intermittent fasting fr the last few months. You hav enlightened me with this magical fasting method. My age s 31 and doing fasting really helps me but some other researchers and doctors are talking about varying fasting hours at various stages of menstrual cycle and Ovulution. So confused now..Pls can you do a detailed video on that ? To help us all through ur valuable knowledge.. pls do consider my obligation.
Hello bhuvee
Low Fasting Insulin but higher fasting glucose. My Fasting Insulin is 3, and my fasting glucose is about 110. A1C is 6.3. Is this insulin resistance? My doc is perplexed. Can you help me understand this situation?
I've found so many good sources about health and nutrition but so far Jason Fung has been most influential. Thank you Jason.
Dr fung love your books it's amazing
Would you have recommendations for fasting with hypoglycaemia? Thank you!
Thanks so much Dr. Fung!.., as always you are so very informative and your research is now saving my life as well as 1000s of others I'm sure. Can you explain why some people develop insulin resistance and others don't even if their diets are similar?
Probably genitics
When I pump iron, I burn so much glycogen that I have a 7 hour window where my blood sugar is stable. Just an idea.
Very clear and concise explanation. Thank you for sharing your knowledge.
Dr. Fung, you're very long winded on the meaning of resistance. 9 min vid 5 mins of example of it.
Dr Fung, can insulin resistance lead to (or contribute to) pathological calcification? Specifically, can IR lead to calcification in the kidneys? My mother's GFR number has decreased significantly this past year, and I wonder if there is an association with IR. Thanks.

and his other vids
Thank for the earphones analogy, Dr. Fung. So easy to understand.
First Thanks Doc!
I dont know anybody insuline resistant in my family or friends despite that they all eats typical polish food as grains and potatoes always with meat
(pork or chicken) and some kind of sauce every day all life. Question is what is exess. All physical active no gym just physicall work or busy life.
Some said Ceramide build up messing with insulin receptor....
Thank you so much Dr. Fung.❤🙏🏽
Love your analogies!
thank you dr. jason fung, i followed your advise, i have done 16 and 24hrs intermitent fasting and proper diet and exercise did reverse my type 2 diabetis. thank you.
How u going now
when you see that 1) you go to the conventional doctor and he fills you with medicines for everything. and you think that the integrative is going to help you and you spend a lot because 2) you go to the integrative (which charges in dollars, is not covered by any insurance, and does not take care of it because it is not a doctor,) it is to shoot yourself. The integrative doctor, like the conventional one, you have to look for it like a needle in a haystack, because most use the same formula, they put you on an elimination diet, they fill you with vitamins and natural medicines (which is not covered by insurance and you pay in dollars) but when you have any effect of these medications, or some symptom sends you to your conventional doctor???? what does that mean???? . In the end, study and be your own doctor, learn to listen to your body, because you know something???? none or few doctors (integrative or conventional) will listen to you and will be supportive of you.
What would hypoglycemia with and a1c of 5.1 mean?
What if the insulinoma is non-resectable? What would be the approach then?
I recommend that everyone in this thread read The Diabetes Code. It was THE game changer for me. THE diabetes ‘problem’ is insulin resistance caused by hyperinsulemia caused by consumption of sugar especially high fructose corn syrup and seed oils.
Carbohydrates do not cause type 2 diabetes.
Fat does, so vegetable oils and animal fats.
Dr Neal Barnard is a diabetes specialist.
Damaged adipocytes due to the breakdown of linoleic acid.
A better explanation would be to say that the cells are stuffed full......and more insulin is needed to force more of the abundant glucose into the cells.
Who on earth signs up for a study to see what happens if insulin resistance is deliberately increased?
Again complicated, doc you can do better in explaining what insulin resistance is simply
Please explain what causes type 2 diabetics patient to get low blood sugar
The main driver is fructose, true fact.
The reality is that insulin resistance is a survival mechanism, just like all biological functions are. If you eat fructose you will stimulate insulin resistance to help prioritize energy to prepare you for a famine. This is why we crave sugar so much. We are supposed to eat fructose in fruit in the fall so we can gain a few pounds, go into insulin resistance and prepare for the winter.
Dr. Richard Johnson has proven this in his evolutionary description of fructose metabolism and why we gain fat.
Just remember, we evolved survival mechanisms to help us survive starvation and a lack of food. One of the evolutionary roles of insulin resistance is is a way to help us gain fat to survive changing metabolic conditions, like a lack of food.
Although there are other causes of insulin resistance, fructose is certainly the main driver.
Most low carb people think just having high insulin causes insulin resistance. It may, but it's not nearly as much of a natural driver as fructose is.
Check out Dr Johnson's work if you really want to understand insulin resistance, metabolic syndrome, diabetes and obesity from a scientific, evolutionary point of view.
Dr. Johnson is right.
What utter nonsense you have written. Did you read this on the internet and now copy and paste it everywhere you can?
Some of what you have copied and pasted is correct but a lot isn't. Fructose can only be metabolised and stored in the liver unlike other sugars such as glucose and sucrose which can be metabolised within body cells.
Insulin resistance is NOT a survival mechanism. It is as a result of persistently high blood sugar levels and the body no longer being able to regulate it through normal insulin production.
It is nonsense to write that we are supposed to eat fructose in fruit in the fall so we can gain a few pounds. Fructose is metabolised and stored in the liver hence people get NAFLD or cirrhosis of their livers.
Please provide the source of your DR Johnson's research that you say has PROVEN his evolutionary description of fructose metabolism and why we gain fat. Which scientific or medial journal was it published in? Your are trying to pass off untested and unsubstantiated opinion as fact.
I don't think you even watched this video as you clearly haven't understood what Dr F was saying. Insulin resistance is at a cellular level where the cell can no longer except any more sugar as it is FULL. Insulin is the hormone that facilitates cells accepting sugar only it no longer as any affect. This is insulin resistance. The cell is resistant to insulin. Enter drugs such as Metformin which make the cell accept more and more sugar as the dose is increased.
The cause of a high insulin level is consuming too many carbs and too much sugar. End of.
You really haven't grasped this have you?
Do you have ANY biological, biochemical education training or qualifications? You just seem to have found something on the internet that fits with your agenda and now you copy and past it everywhere you can. Nutz.
A simplified explanation, but it is true. There are mechanisms behind this and the simple fact is that the cells are overloaded with stored glucose by the time insulin is high. The Randle Cycle is also involved. The net result is just as Jason says. You don't really need the details. Just cut the glucose, fast and empty those fat cells.
How about those diabetic who are on dialysis due to renal failure? Will LCD and fasting heal them? Answer please
So that is fine, but once again: How does fructose causes insulin resistance?
You are soooo good! You truly are a great educator. I wish more people would listen to you, including the MDs.
Dr. Fung. Can you also talk about goiter and thyroid nodules with hashimotos? Thank you.
This is outright medical desinformation. There is a large body of evidence demonstrating that insulin resistance is not caused by physiological hyperinsulinemia but by increased amounts of adipose tissue, which causes the release of inflammatory factors (adipokines) and free fatty acids. These two factors mess with the function of insulin receptors on body cells. Yes, under certain pathological or experimental conditions with continuous high insulin levels, insulin resistance also occurs. We see this for example in insulinomas and when insulin is continuously infused over a period of at least several hours. However insulin resistance induced this way is transient, meaning it reverses the very moment the iv drip or the tumor is removed. In addition, in this video Jason Fung chooses to ignore a large pile of randomized controlled trials in humans clearly demonstrating that the amount and type of carbohydrates in a diet has no discernible effect whatsoever on metabolic status. If you control for calories that is. The bottom line is that conditions related to insulin resistance such as NIDDM and metabolic syndrome cannot be reversed by manipulating the amount carbs consumed. These conditions can however be reversed by creating an energy deficit. Yes good old CICO. Don't let anybody fool you otherwise.
Yes! Also there have been several peer reviewed randomized controlled studies that fasting is no more beneficial than calorie restriction for health and weight loss!
@@Hat65 You are correct. Btw, I am practicing IF in my weight loss journey because I like it and it helps me to maintain my caloric deficit. It's a tool, not a gospel.
thanks 🙏🏽 Dr Fung.Excellent explaination always
Ok, there is an idea that high insulin causes insulin resistance. There may be some truth to that, but I can confidently tell you that it is not the main driver of insulin resistance, metabolic syndrome, obesity or diabetes.
How do I know that?
Simple, because of history. If high insulin was the primary cause of insulin resistance, then every society that ate primarily starches like the Japanese, Tukisientans, Central Americans, South East Asians would have all be suffering from staggering amounts of diabetes.
We know this is not the case because many farming societies have been eating rice, bread, potatoes in huge amounts for thousands of years without getting insulin resistance, diabetes or even struggling with obesity.
This also disproves the idea pushed by Bart Kay and others that the Randle Cycle is causing metabolic disease too.
If just high insulin caused disease, then diabetes would have most likely been more rampant.
I have found that the real cause of disease is fructose consumption. When you add fructose to a society's diet, diabetes becomes a huge factor.
None of the ancient societies started getting sick until they added sugar to their diets. They were perfectly healthy on carbs and starches until they started eating sugar, more specifically fructose.
Glucose and fructose are not metabolically the same. They are metabolized differently, and have different metabolic effects of the body.
The reason nobody seems to understand this logic is because they are looking at disease from the wrong perspective. They are just looking at the science without regard to evolution. Since us humans evolved, we need to not just use science to attempt to explain what we should eat and do to stay healthy, we need to use science to figure out how we evolved. All animals evolved, and evolution always tells the truth.
Fructose is our evolutionary survival nutrient, but since we eat way too much, it's making us sick.
So basically if one stays away from fruit or products that use fructose in their ingredients you will not become insulin resistant?
@@dianepereira1860 This seems to be what CJB is saying although they do seem quite confused. They seem to be under the impression they are more informed than Dr Fung on insulin resistance, they know something he doesn't and are trying to educate him. LoL.
@@dianepereira1860 No, I'm certainly not saying that. I think insulin resistance has many causes. I believe however fructose causes the most insulin resistance in humans worldwide.
@@alexmorgan3435 Yes, of course nobody has a monopoly on the truth and anybody can learn things others don't know including me and you.
@@ClassicJukeboxBand thanks for clarifying. Yes it is a complicated issue.
So, taking Insulin to reduce Blood Glucose is bad ?
