Listening to Dr. Fung when I first learned I had diabetes was instrumental on me understanding that this was NOT a progressive and chronic disease. I listened to everything I could from him and have turned my life into something so much better. I reversed my diabetes through LCHF diet, intermittent fasting (some prolonged fasts as well), and exercise. I went from an A1C of 13.2 at the end of June 2022 to 5.5 in January of 2023. I also happened to lose 36kg (80lbs.) so I guess by following his guidance it has cost me to lose a full wardrobe of bigger size clothing. Thank you from the bottom of my heart Dr. Fung! I would be in very bad shape and getting worse if I'd listen to my current GP.
Congratulations! Even most regular doctors don’t give the same advice that Dr. Fung does for solving the problem at the root cause. They just put us on medicine, mask our symptoms, and never explain the real causes of the problem. They are, therefore, gradually helping to kill us. This problem affects multi millions, if not billions, in the world. But only a select few know the truth. Where’s the media on this?
Dr Fung not only had the insight to recognize the root cause of diabetic kidney disease, but the courage to speak out against the conventional wisdom, which was just about treating the symptoms. Top man.
How much time it takes to loss waight first week second week and what %of carb fat and protein did u consume during waight loss and after loosing weight do u still slim or not ?..?
My father-in-law was a renowned family practice doctor in the 70s and 80s. He became so obsessed over reducing his heart attack risk through lowering his fat intake that he began to strive for a zero fat diet, following it for a number of years. He eventually developed Alzheimers and became completely dependent on a 'girlfriend' - who embezzled most of his life savings. A very sad story that has reverberated down through all of his descendents. And it is just one among many. This whole low-fat debacle has cost us dearly as a nation.
Hi Sheila … my Nana who lived until she was 106 ate animal fat all her life … butter/ dripping / cream … I once asked her about this and she said she didn’t want to starve her brain !! … she had a fantastic memory up until the day she passed away.
Jim Fox ... embraced the marathon culture,and wrote several books...his father and grandfather died of a heart attacks at exactly age 50....so after over 20 years of the running lifestyle...he finally died of a heart attack at age 51.....the medical society immediately said (you see it's all genetic)....the runners world magazine rebuttal was ...(what are you talking about...he gained an extra year of life from running)....there are pros and cons in everything....the majority of centennials are meat eaters
Exactly, Sheila. I saw an interview on Dr Anthony Chaffee's channel where this man at the assisted living homes he owned was helping the elderly with a change of diet...off of carbohydrates. The changes have been miraculous, including memory improvement and a few of the residents even getting to go back to their homes or with their families. Diet is so important. Everyone should take note of your post.
That’s for sure Sugar is the poison but of course the Pharma ,Kellogg and cereal company is the consumers enemy. Dr. Fung is one of those honest doctor.
Dr. Fung, you changed the course of my health. My grandchildren thank you. Thank you so such for sharing your knowledge, direct and simple. Sugar bad, eggs good.😂
The one-two punch of doctors. Doctor Perlmutter and Doctor Fung in my humble opinion are the two best doctors at explaining the effects of nutrition on health. Thank you good doctors.
I eliminated carbohydrates/sugars, started fasting for 18h and occasionally OMAD, zero processed foods, exercise every day, and natural supplements to lower glucose and others to increase metabolism and muscle. My glycated hemoglobin went from 8.5 to 5.7 in 3 months.
It’s been “burned “ into our minds that we always have to be eating, which is completely far from the truth . I’m so blessed I found Dr Fung , my son and I have lost so much with intermittent fasting! Thank you so much Dr Fung 👍🏽👍🏽🙏🏼
Starving the body from lack of nutrients is bad for the body and the digestive system,which needs to be constantly flushed out......an occasional short 16 hour faste is much better than a multiple day faste.
who burned it in to your mind, don't watch cooking shows and tv adds. i work all the time and only eat to give me energy to work. too many people live to eat rather than eat to live..
@@mslice09fasting is not starvation. It is true that some people should not fast (meaning that they are already severely malnourished and are at a very low bodyweight/fat-stores) but generally speaking, in our extremely overweight society, a properly done fast is almost like a fountain of youth (stimulating autophagy). You should look into what happens during a 48- and 72-hour fast...it is almost like a brain reset. Extremely beneficial and rejuvenating. 👌✌️
Once a year I come to check on Dr. Perlmutter. This man is still glowing and his jawline is sharper than last time. All that aside, I learned a lot from Dr. Fung years ago and I integrated it into my life with great results. Thank you both. 💕
Two of my favorite people answering questions about diet... I hope you do it more often to bring this to light. I've heard this information before, but told it in a different way, always good to hear it again.
My fat doctor kept telling me everything in moderation, when I told him I went carnivore. I recently saw him for a routine exam and was surprised when he said he had lost 20 pounds in four months after going low carb. :)
My doctor (not fat, but traditional) had a similar response when I dropped 25LBS. She said every patient promises to lose weight and nobody actually does.
@D For now, ignore the LDL reading and work on lowering TRIG. by going low carb keto or zero carb carnivore. As it is TRIG is high because the body is overloaded with fat. There is nowhere for it to go. Switch diet to low or zero carb forces your body to start using body fat, reducing TRIG.
I went LCHF, IF and started walking 2 months ago. On 4 meds for t2d. Stopped 2 right away. Now on insulin degludec and metformin. A1C from 10.4 to 6.4. Blood sugars around 110. Should I stop the insulin?
Ok, another testimonial about the positive effects of intermittent fasting/eating. 7 weeks ago ( after a mildly successful couple months with Noom, lost 10 pounds ), I came upon a video on fasting by Dr Fung. I watched the video, and I liked the video. I decided I was going to try intermittent fasting. The day after my watching Dr Fung's video on fasting I skipped breakfast ( phew, what a relief, I've never been hungry in the mornings and ate in the mornings because I've heard my whole life it's the most important meal of the day ) and had 2 meals. 2 delicious nutritious meals - whole foods, animal meat, plants, veggies, nuts, water ( just started adding fermented foods.) Since my first day of 2 meals a day, an avg of 17:7 fast/eat window - it's been 45 days. 45 days ago - 212lbs , 5'10" male 43yrs old Today - 189.5lbs , I'm still 5'10", I'm still male, but 2 months older. 22.5 lbs of dropped water, and fat and whatever else - in 45 days ( 1 month and Half ) by eating 2 meals a day with virtually no snacking and only water and coffee!!! I have high percentage dark cocoa chocolate 70% and higher with natural peanut butter sometimes when I'm hungry in between meals. I add sweetener to my coffee with heavy cream every day ( the sweetener is awful for me but I'm sugar addicted and thought to tread carefully here, and so I still have some sugar.) When I really feel I need it ( which is rare ) I'll have processed carbs like an occasional cookie, or slice(s) of bread. But much much much less than before. I have hypothyroidism, and take a pill every morning. I've done a couple 24hr fasts in my 45 days. IVE LOST 22.5 POUNDS IN A MONTH AND A HALF. - after eating terribly, absolutely terribly for the last 2 years ( was going through personal trauma and ate for dopamine hits.) A reversal this quick, by ...... 1. Skipping the most important meal of the day ( sarcasm ), 17:7 fast, eat window 2. Consume less sugar and refined Carbs by approx 80/85% 3. Eat delicious, real, whole foods ( not processed ) from the earth. Steaks, chicken, salmon, Brazilian nuts, rainbow of veggies, fermented foods. I take occasional fiber supplement , the only supplement I take called Inulin. 4. Respecting the process. At first I indulged in more sugar and carbs. Of course I did. I had been my whole life 43 yrs. I'm a food junkie. So I reminded myself to be patient. When I stumbled, I would assure myself that till the next meal I would commit to staying clean. Patience. 5. I have to include Marc Sisson. I read 2 meals a day before Obesity code - and Marc and his Co writter were the first to make me believe that I could do this. And I have. I did it. There were some bumps in the road of course, but I stayed on track. Now, when I feel pressured to eat something I don't prefer to put in my mouth ( I.e your invited to someone's home and don't wish to be rude ) I say fck it, and I eat whatever I want, KNOWING, that I'm armed with fasting in my arsenal. So I indulge and fast away my indulgences within a couple days!!!! Metabolic Flexibility is the name for that !!!!!! Hey you don't believe us?? Just try it. Goodluck
Wow… I am a huge fan of yours now!!! You are speaking my language! Not from a vocabulary standpoint, as I had to look up about 14 words from your presentation on a different channel, lol, but from a genuinely intelligent and inquisitive human whom simply wants to empower others to take back their lives from going down the wrong pathways. Love and health to you good Doctor! You are a blessing. You remind me in looks and demeanor of my Mom and Dads Cardiologist Dr. Brian Donahue. He’s a great Doctor as you are and I wonder if he knows of you. I’m going to ask him next time I take my parents to see him. He’s from the Pittsburgh area UPMC.
Thank you. We (my husband and myself) followed The fast 800 diet for 12 weeks (we'd been Intermittent Fasting for 5 years) and I dialed myself back from DT2. We both lost 2+ kilos. We both lost belly fat and centimetres. It takes commitment and is not cheap. Carbs are cheap and quick to prepare. I have an auto-immune disease, on steroids, fatty liver, so still struggling with obesity. What about all those POOR drug companies. If people begin to improve their health with healthy food those poor companies will lose revenue! My French doctor here in France has not caught up with the low carb research. I hope he does one day. He still believes fat makes us fat and he's not an old Dr.
👏 brilliant explanation Whenever I feel like eating snacks I always turn on to Fungs' video and listen to his talk on junk food and how they spike bsl. Thanks doctor
Interesting fact: in bodybuilding, immediately after weight training, for muscle building purposes it’s beneficial to drink fast digesting protein along with insulin spiking sugar like dextrose. I used to do it regularly, never gained weight but gave me cavities so had to switch to an alternative. In order to remain anabolic, the general idea was to eat slow digesting protein along with low glycemic carbs/fat throughout the day. Noticing where your body puts what you consume matters for results.
Years ago I remember reading in fitness magazines, “ If you switch from an automatic transmission to a standard transmission, you will loose 10 lbs. in the course of a year! 😀 I switched from an average of 4 cans of soda to 4 cans of diet soda a day, and after 1 year lost 0.00 lbs.! Cut 600 calories a day - zilch!
That is what I've always thought! How sad when people that work in Health care look sicker than me! So how are they going to help me? Great video! 💞love you both!
I am a registered dietitian ; I can tell you in our profession; people believe IF and time restricted eating is extreme. No what’s extreme is 1/3 people obese, 1/3 people diabetic That’s extreme!!!!
The dietitians who seem to get time by the media all seem to advise people to eat lots of whole grains, fruits and vegetables, and reduce the fat consumption. That has not worked since the first time someone said to eat more grains and yet dietitians continue to say it. Why?
Dietitians promote a varied diet focused on protein, vegetables, whole grains, beans, nuts, seeds, olive oil, avocados and some dairy products. They emphasize whole grains as a healthy part of a diet which is true, we work directly with the public and often find they are consuming way to many processed foods, fast foods etc, so dietitians who get media time give a good I sight to a healthy diet, a varied unprocessed diet. They/we recommend whole unrefined grains like oatmeal, rice, whole grain breads and pastas, and if a balanced you can consume those foods; take a look at the Mediterranean diet. Thanks.
I was hoping to hear a discussion about uric acid .. Dr Perlmutter's new book "Drop Acid" and Dr Fung as a nephrologist would both know a lot about this interesting new hypothesis. Ditching fructose is the key once again.
Dr Fung, thankyou so much for the work and the education! Question: in your description of old school calorie counting paradigm - you talk about the drop in metobolic rate as causing "a constant feeling being cold" as an indication that it was perhaps a short term solution that will be short lived. I gave up bread, most processed foods and most sugar... I am doing 16/8 plus occasional 2 and 3 day fasts, but I am definitely not dieting or restricting calories .... and I've lost 60 pounds in 6 months 🎉 I exercise at least 60 mins almost everyday (in fun ways)..... However I must admit I am cold all the time. ❄ I can cope witlh it easily with warm clothing.... it's much better than being too hot! But your comment has me worried. Does being cold all the time indicate something negative about my weight loss process or the speed that I lost it??
Dr Fung is right. Context and amount matter. I have a half cup of blueberries or blackberries with my unsweetened full fat Greek yogurt once or twice a week. That's good, I get vitamins, fiber and variety in my diet without too much of a carbohydrate load. Drinking a lot of juice or several bananas would be different.
You guys are awesome thanks for sharing your knowledge you’re both great speakers. I am learning a lot. There is so much more to learn. When I went through college of medicine, we sure did not learn anything like this. Your talks and podcasts should be requirement in medical school. We have not been practicing medicine and just like you said tx sx not the disease. I wish I had known as 20 30 years ago.
I have been struggling with Diabetes for 30 years, I now do intermittent fasting 16/8 and I am in Mounjaro ,trying to do better,riding my recumbent bike 4 miles a day, three times a week, thanks for sharing
Hi! Kudos to you to start intermittent fasting. Have you check out dr fung channel. I came across dr fung channel by accident and followed his tips and advices I lost 17 lbs in 4 months. If you read the comments from dr fung channel you will see people with diabetes were able to reverse their diabetes and get off their medications. Good luck!
I’ve been fasting clean for a little over a month. Had a 20 oz Coke Zero and the flood gates for sugar cravings soared! I have to be very careful with artificial sweeteners as much as sugar.
WOW Great and wonderful and useful Information I told my doctor About this he was against this he is no longer my doctor I am loving IF….Thank You Dr. Fung..I will be checking out your Channel, Dr. P.
Hello, I need a little guide here, My Dad is already doing dialysis. How can I improve that condition if the damage is already done? I changed my lifestyle 5 years ago, but I couldn't change his because we are in different countries at the moment. I just wonder if at this point is something that can be done to improve his condition
As someone who does a lot of research on nutrition, this is very interesting. What I am wondering is, is there any research on ketosis lowering insulin resistance?
Yes , that’s one of the mechanisms of ketosis is not needing higher insulin levels to put glucose into cells . You use an alternative source of energy called Ketones that doesn’t need insulin too much at all . It helps one pull out fat stores too to use for energy & lose weight & defat one’s liver .
And these lying doctors gets a nomination every year, while the Honest doctors like Jason and a few gets laughed at for speaking the truth. I’m 48, fasting, and never felt better. Give these gentlemen a nomination!
I eat whenever I´m hungry, but I don`t eat sugar for decades and no bread since 12 months ago, the main meals are lot`s of vegetables (up to 1 kg/day) with meat and oliveoil, no carbs...in the morning or between some oats with apple and curd cheese and/or fatty yoghurt, in summary mostly ~ 150g oats/day in ~ 3 portions, (= 25 -30% carbs ) with veggies I estimate ~ up to 40-45 %....I don`t expect any substantiell bloodglucose spike and fat storage ever from ~ 50g Oats buffered with fat/protein.... lost a little weight, 61 yrs 71kg, BMI 20,7 I don`t eat any processed food/carbs...and oats are much cheaper... Some other opinion I heard, by consuming carbs, processed and/or in higher quantity you better do intermed.fasting. We burn some 100 kcal/hour, every excess goes to body fat, by slow impact of low glycemic load and muscle activity there is no excess. Of course, if your "snacks" are 600kcal pure crap...some 450kcal goes to fat storage.
I appreciate everything mentioned but we keep focusin so much on obesity. My family has too many normal bmi relatives who are prediabetic or are diagnosed w diabetes. Can you please touch on what’s happening with them and their bodies? Most do not workout or control their food intake. They believe because they have normal bmi or are skinny they are blessed… despite the diagnosis
Some cultures such as Asian and Indian .. have lower thresholds to insulin resistance. Even though they appear to be thin .. they have higher rates of Diabetes. The fat % in their bodies may be the same as someone else .. but because of this lower threshold to insulin .. they are more prone to Diabetes and other illnesses that stem from it. As a result .. their diet (predominantly high in carbohydrates/glucose) perpetuates this huge problem. Dr. Nadir Ali, Dr. Ken Berry and I believe Dr. Jason Fung have videos explaining this. India and other Asian countries have the highest rates of Diabetes in the world. I’ve heard it called “skinny fat” ✨
@@Ingridvieira310 I am Asian and a lot of family members now reaching their 40s are prediabetic. My question is very personal unfortunately and I refuse to believe it is solely genetic. I think we also feed ammo into the gun/disease. Genetics is the trigger
Dr. Fung's book, "The Obesity Code" is an incredible compilation of current science and lay-person friendly explanations of both obesity and type 2 diabetes. Thanks for this informative interview and discussion with Dr. Fung. I bought several copies of his book and gave them to family members a couple of years ago. (Retired Internist here.) :)
Very good lecture I could say. I would just add the knowledge that each one has their personal fat threshold and each one has their own insulin grade of secretation genetically determined. Thats why 2 people eatong exactly the same food and doing the same things may gain fat diferently
Hospitals, doctors offices and schools should be places where good nutrition is taught and provided not places that contribute to disease and obesity. It is crazy the hospitals are feeding people the very food that caused the heart disease, high blood pressure or cancer that they are treating. Every person in the hospital should receive some nutrition education before being released. Every doctor visit should be an opportunity to educate patients about how food choices impacts their health outcomes. The fact that doctors do not get nutrition training as part of their training makes no sense. Medicare and Medicaid should require nutrition education as part of patient care. Focus should be on food choices. Fasting should be investigated as a treatment for disease.
What if I don't like fat or animal food, is eating beans and lentils and brown rice and fruits and vegetables good? I've been running on these foods only and I don't see anything wrong
Does food aroma help with satiety? I’ve been doing real food and eschewing processed food since the beginning of 2023. I’ve noticed when I cook with ghee and Asian sesame oil, the aroma seems to make me feel a little fuller before eating.
Dr. Fung, WHO (and when?) originally came up with the concept /practice of prescribing insulin to treat high insulin ? (at about 10 minutes into the video)
I would love to hear Dr fungs view on the book ( mastering diabetes). They have been curing diabetes on a high carb, low fat diet High in starch and fruit
Last night I had strawberries after dinner and now blueberries after lunch. Yum I purchase them frozen to ration them sparingly and reduce spoilage. My problem this week was making whipped cream; I went thru 2 pints of HWC and gained a few pounds. Lesson learned
@@gailstrickland221 it can be easy to drink your calories, they don't trigger the same satiation as solid food. I sometimes have full fat milk fortified with extra cream after exercise but it can be easy to overdo it.
In the UK insulin is often given to type 1 diabetics where's as metforman is given to type 2 diabetics. Metformin does not put on weight. Does anybody know if it's okay or bad to have Metformin for type 2 diabetes?
Metformin seems to get the go-ahead by low carb proponents if your blood sugar is still high when diet is improved. It boosts insulin sensitivity instead of increasing insulin.
Sure seems like Health Insurance Companies and Medicare would be receptive to a WFPB vegan message. It would save them money on health care costs. This could off set the lobbying by food manufacturers. Maybe educating health Insurance Companies and Medicare administrators should be a priority. Health Insurance companies might even push doctors to take nutrition more seriously by paying for nutrition counseling of patients.
This should be everyone's healthy living lifestyle. If you don't cut out ALL SUGARS and things that convert into sugars, don't do long term intermittent fasting of 16/24+ hours which is the most important recommendation on this list or don't get enough good sleep (don't eat past 6:00pm) you will not lose the bad fat weight nor gain the good muscle wight effectively, nor create a healing environment for the body to heal itself because you're limiting the bodies ability to produce HGH which helps make testosterone which does all sorts of wonderful things in the body. When I eat I eat high good fatty meats like a good 6oz rib eye steak with all the fat, whole eggs, fermented foods such as kimchi, butter, uncurred bacon, salmon, sardines, oysters, avacado, cheeses, healthy oils like olive healthy nuts like Almonds, Brazil, Chestnuts, Brazil, Hazelnuts, Macadamia nuts, Pecans, Pine nuts, sea salt, and if I'm in the mood for plant based foods I make sure they are of the cruciferous variety. Also the introduction of Boron in your diet also helps with the production of free testosterone along with, chlorella which is a natural algae that is purported to remove heavy metals and toxins from the body, along with Zinc 50mg, D3 10,000 iu, Magnesium, Niacin and maintaining a good gut flora with probiotics. I add additional vitamins such as trace minerals in my diet if I find I'm deficient in any one in particular.
The point about diet soda causing weight gain makes total sense. I didn't drink diet soda for two weeks and I had no cravings for junk food and I felt so much leaner after such short period of time. I really should quit drinking it once and for all.
I love this conversation, However I started keto & IF in Aug thru Thanksgiving, never lost a lb., so I switched to ADF & black coffee, for 6 weeks, never lost a lb., after Christmas moved to high fat keto with zero sweets, & gained weight. Please help I'm so frustrated
Have you got your hormones check? I was in the same situation but it was my hormones. Cortisol was high, progesterone was low, so no matter what I do, I would not lose weight. This is something that is happening and not really discuss. Now, I got my hormones align, I am finally losing weight with IF and Keto. I hope this help.
In this world we obey the laws of thermodynamics. Although hormones affect how efficiently we process calories, ultimately you need to be in a calorie deficit to lose fat. Fat is 9 calories/gram. Adipose/fat tissue is 87% fat/lipid. You need a 7800 calorie deficit to lose 1kg of body fat. If you have not lost weight, you have not eaten little enough for a long enough time period. If you want a hack or an excuse then blame hormones, bad luck, genetics or being a special snowflake. If you want to get what you always wanted, count your calories, accept that this is very tough and will take time and determination.
@@jackglass9226 I participated in Optivia or formally known as medifast. Counting calories will work, for awhile, until your body continually adjust to the lower calories, then you gotta live on 5-600 calories, which is not sustainable
@Petricia Hice I'm currently maintaining 13% body fat on 2200 calories. I have never heard of anyone neededing as little as 500-600. Could you explain with what mechanism your body is adjusting your caloric output to be so low? Your caloric output is made up of your base metabolic rate, thermal effect of processing the food you eat (0-3% for fat, 8-12% for carbs, 20-30% for protein), thermal effect of exercise and non-exercise movement thermogenesis. Those with severe metabolic disorders may have a 20% reduction to their base metabolic rate. Even if you have hashimotos, weigh 50kg, eat only 500 calories, and lie down in a dark room not moving at all for 24 hours that would give you BMR of 900 and TEF of 50 giving you 950 calories used for those 24 hours. Please show your math :)
@@jackglass9226 medifast or Optivia, uses 1 meal & 5 fuelings. The 5 fuelings are 100 calories each, your 1 meal varies, but very low fat & low carb. So it's around 4-500 calories. Most time averages 900 to 1000 calories a day. Eventually your body adjust to that calorie count & you stop losing weight, so you have to continue to lower those calories. Finally I realized Its unsustainable.
I read some of this book in March and had an endocrinologist appointment in May. I've lost 10 pounds since mid May '23. Calorie counting has been a huge lifestyle change for me but my doctor recommended an app called LOSE IT. It's truly an incredible tool - calorie counting. I used to think it was tedious but after being told I was prediabetic with another underlying health condition it was time to make a change. I'm going to complete the rest of Diabetes Code too.
I have used that app and loved it. I like reporting everything I eat because it makes me cognitive of what I'm eating. I count total carbs, fat and protein.
My grandmother died 103 with type I since age of 40, never had any insulin injection, never had more than 1.00 glucose in blood, she managed it with artichoke and topinambour, she took metformin I think, that's all. She basically had zero insulin in her blood, so insulin is optional. She looked obese, but I realise today that she was metabolically healthy.
I doubt she had Type One Diabetes but she had Type Two - otherwise, she would lose weight & her muscles would waste away. It causes organ failure , blindness , losing one’s limbs & death without any insulin being available in one’s body made by the pancreas . Metformin is for Type 2 Diabetics .
@@heidivernathorbjornsen475 while she lived 102 I never saw a blood test with other than zero insulin. She was functioning like that. I don't know if she had type I or II buy anyhow her pancreatic head islets of langerhans did not show trace of its presence in blood tests. She always was mild obese and always had the mindset of a tank.
I lost 10 pounds in 2 months very comfortably without feeling extreme hunger and fatigue thanks to intermittent fasting and low carb diet style. It’s a part of my life now. I hadn’t been able to lose these 10 pounds for three years.
I watch net carbs of GREAT food and am starting the fasting. Process. I a, really feel😮ng good. Today I am at 16 hiyrs..not a lot but busy and ok. But I had a big meal at midnight because I was busy. And I had a steak sautéed mushrooms and egg. And some milk poured whole milk. Thank you. And I went to sleep but I got up this morning and I am feeling really good and it’s now about 3 PM and I will probably do a 20 hour fast and then Nibble on some good stuff and feel better. And maybe take a nap which sounds good.
This was years ago that I don’t even want to tell my PCP what hurts otherwise I will have like 10 px after. Everytime you tell him something he has tons of different px for it. He has his px pad with him all the time.
For weight loss, a few zerocarb days a week works great. So does a few days with no food, but the amazing thing about fasting is all the health benefits! Some of the many benefits of doing occasional extended fasting: Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body. Blood pressure is quickly and dramatically lowered. Fribrosis/scarring is reversed over time and telomeres are lengthened, which also helps with lung fibrosis. The hunger hormone ghrelin lowers with extended fasting and rises from dieting. Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy! Fasts from 36-96 h actually INCREASE metabolic rate due to norepinephrine release! Reflexes and short term memory are increased. Thymus is regenerated, which suppresses aging and renews the immune system. Fasting increases nitric oxide. Fasting stimulates phagocytosis, the ingestion of bacteria, plaques and viruses by the immune system. Weight loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods. Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus. Losing weight through intermittent fasting shows greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period. When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state. What breaks a fast? Anything with protein or carbohydrates in it will break a fast, though if the amount is tiny you will go back into ketosis very quickly. Most teas and herbs are OK. Most supplements and meds will either break ketosis directly or contain a filler that will. Many medications are dangerous to take while fasting so you may have to talk to your dr. about discontinuing them during a fast. Fasts of several days will not affect short term female fertility and may increase long term fertility, especially in women with PCOS. Does fasting lower testosterone? No, it raises it when the fast is broken by increasing lutenizing hormone and helps build muscle by increasing insulin sensitivity! The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again! Does the body preferentially prefer glucose as a fuel? No, your body always runs mainly on fat except for brief periods of very intense exercise. Your brain also prefers to burn ketones at a rate of around 2.5 to 1 when they are available in equal quantity to glucose. Fasting stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses. Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more. It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention! Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers. In fact, the biochemical regulator of BDNF production is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting. Fasting also increases telomere length, negating some of the effects of aging at a cellular level. A fasting mimicking diet for 3-5 days in a row also provides many of the same benefits as water fasting. FMD usually has 200-800 calories, under 18 g of protein and under 18 g of carb. Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia. Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or certain forms of hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution as it could lead to ketoacidosis. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

@@anomarnamloh7444 There is only so long you can conduct metabolic ward experiments as they are expensive. People aren't going to stay there unless you are paying them well. However no matter who they bring in. No matter what health conditions they have or they are perfectly healthy. The law of CICO applies and works perfectly 100% of the time when tested. IT is amazing what happens when you measure things accurately and even more so when people are unable to cheat.
@@Ryan_DeWitt I think even these two gifted men would have difficulty counting the cals. So no it dont work. Plus we all know they never bring back all the biggest losers cos they cant maintain the wacky Low cal stuff.
@@ClassicJukeboxBand And yet the human body requires energy to operate. What happens when one feeds the human body more energy than it needs? What happens when one doesn't feed it enough energy?
Most doctors got one day's worth of nutritional training and it probably happened 20 years ago. They suggest what is basically considered common knowledge instead of modern science. Apple juice is just as bad in every way as drinking soda.
Listening to Dr. Fung when I first learned I had diabetes was instrumental on me understanding that this was NOT a progressive and chronic disease. I listened to everything I could from him and have turned my life into something so much better. I reversed my diabetes through LCHF diet, intermittent fasting (some prolonged fasts as well), and exercise. I went from an A1C of 13.2 at the end of June 2022 to 5.5 in January of 2023. I also happened to lose 36kg (80lbs.) so I guess by following his guidance it has cost me to lose a full wardrobe of bigger size clothing. Thank you from the bottom of my heart Dr. Fung! I would be in very bad shape and getting worse if I'd listen to my current GP.
Congratulations! Even most regular doctors don’t give the same advice that Dr. Fung does for solving the problem at the root cause. They just put us on medicine, mask our symptoms, and never explain the real causes of the problem. They are, therefore, gradually helping to kill us. This problem affects multi millions, if not billions, in the world. But only a select few know the truth. Where’s the media on this?
Good work! Keep it up :).
Yes!! Congratulations to you! Awesome 👍
In 6 months losing 36 kilo’s? That’s awesome
You have cheated the medical industry of the money they expected from you.
Dr Fung not only had the insight to recognize the root cause of diabetic kidney disease, but the courage to speak out against the conventional wisdom, which was just about treating the symptoms. Top man.
47:28 Dr. Fung changed my life. I lost 40 pounds went from obese to healthy weight; pre-diabetic to normal A1C.
How much time it takes to loss waight first week second week and what %of carb fat and protein did u consume during waight loss and after loosing weight do u still slim or not ?..?
My father-in-law was a renowned family practice doctor in the 70s and 80s. He became so obsessed over reducing his heart attack risk through lowering his fat intake that he began to strive for a zero fat diet, following it for a number of years. He eventually developed Alzheimers and became completely dependent on a 'girlfriend' - who embezzled most of his life savings. A very sad story that has reverberated down through all of his descendents. And it is just one among many. This whole low-fat debacle has cost us dearly as a nation.
Hi Sheila … my Nana who lived until she was 106 ate animal fat all her life … butter/ dripping / cream … I once asked her about this and she said she didn’t want to starve her brain !! … she had a fantastic memory up until the day she passed away.
Jim Fox ... embraced the marathon culture,and wrote several books...his father and grandfather died of a heart attacks at exactly age 50....so after over 20 years of the running lifestyle...he finally died of a heart attack at age 51.....the medical society immediately said (you see it's all genetic)....the runners world magazine rebuttal was ...(what are you talking about...he gained an extra year of life from running)....there are pros and cons in everything....the majority of centennials are meat eaters
Exactly, Sheila. I saw an interview on Dr Anthony Chaffee's channel where this man at the assisted living homes he owned was helping the elderly with a change of diet...off of carbohydrates. The changes have been miraculous, including memory improvement and a few of the residents even getting to go back to their homes or with their families. Diet is so important. Everyone should take note of your post.
So sad to Here 🥺 your story
That’s for sure Sugar is the poison but of course the Pharma ,Kellogg and cereal company is the consumers enemy. Dr. Fung is one of those honest doctor.
Dr. Fung, you changed the course of my health. My grandchildren thank you. Thank you so such for sharing your knowledge, direct and simple. Sugar bad, eggs good.😂
Prof Tim Noakes is a legend. So glad you gave him credit!
The one-two punch of doctors. Doctor Perlmutter and Doctor Fung in my humble opinion are the two best doctors at explaining the effects of nutrition on health. Thank you good doctors.
I eliminated carbohydrates/sugars, started fasting for 18h and occasionally OMAD, zero processed foods, exercise every day, and natural supplements to lower glucose and others to increase metabolism and muscle. My glycated hemoglobin went from 8.5 to 5.7 in 3 months.
It’s been “burned “ into our minds that we always have to be eating, which is completely far from the truth . I’m so blessed I found Dr Fung , my son and I have lost so much with intermittent fasting! Thank you so much Dr Fung 👍🏽👍🏽🙏🏼
Starving the body from lack of nutrients is bad for the body and the digestive system,which needs to be constantly flushed out......an occasional short 16 hour faste is much better than a multiple day faste.
U can eat whenever u want as long as u get right nutrients and keep calories in check
who burned it in to your mind, don't watch cooking shows and tv adds. i work all the time and only eat to give me energy to work. too many people live to eat rather than eat to live..
@@mslice09fasting is not starvation. It is true that some people should not fast (meaning that they are already severely malnourished and are at a very low bodyweight/fat-stores) but generally speaking, in our extremely overweight society, a properly done fast is almost like a fountain of youth (stimulating autophagy). You should look into what happens during a 48- and 72-hour fast...it is almost like a brain reset. Extremely beneficial and rejuvenating. 👌✌️
Love dr Jason Fung ! Thanks for having him 🙏🏻🌹✨🙏🏻
Jason, great info on diabetes. Been listening to you for 2 years, applying the principles of reversing sugar. I’m now off insulin taking no meds now.
Fantastic!!!
Once a year I come to check on Dr. Perlmutter. This man is still glowing and his jawline is sharper than last time. All that aside, I learned a lot from Dr. Fung years ago and I integrated it into my life with great results. Thank you both. 💕
That jawline and his eyes (perpetually blinking) have had some work done on them...
Wonderfully encouraging! I don't have diabetes but after doing alot of research intermittent fasting is my new lifestyle and I feel great
That's the only way to go if you want to keep you weight down.
Two of my favorite people answering questions about diet... I hope you do it more often to bring this to light. I've heard this information before, but told it in a different way, always good to hear it again.
I was literally thinking the same thing!
My fat doctor kept telling me everything in moderation, when I told him I went carnivore. I recently saw him for a routine exam and was surprised when he said he had lost 20 pounds in four months after going low carb. :)
Kudos to you for speaking out and your doctor for listening!
Yes, glad to hear your doctor was humble enough to learn from you.
My doctor (not fat, but traditional) had a similar response when I dropped 25LBS. She said every patient promises to lose weight and nobody actually does.
@D For now, ignore the LDL reading and work on lowering TRIG. by going low carb keto or zero carb carnivore. As it is TRIG is high because the body is overloaded with fat. There is nowhere for it to go. Switch diet to low or zero carb forces your body to start using body fat, reducing TRIG.
I went LCHF, IF and started walking 2 months ago. On 4 meds for t2d. Stopped 2 right away. Now on insulin degludec and metformin. A1C from 10.4 to 6.4. Blood sugars around 110. Should I stop the insulin?
DR. FUNG makes a lot of sense, incredible information
Ok, another testimonial about the positive effects of intermittent fasting/eating.
7 weeks ago ( after a mildly successful couple months with Noom, lost 10 pounds ), I came upon a video on fasting by Dr Fung. I watched the video, and I liked the video. I decided I was going to try intermittent fasting.
The day after my watching Dr Fung's video on fasting I skipped breakfast ( phew, what a relief, I've never been hungry in the mornings and ate in the mornings because I've heard my whole life it's the most important meal of the day ) and had 2 meals. 2 delicious nutritious meals - whole foods, animal meat, plants, veggies, nuts, water ( just started adding fermented foods.)
Since my first day of 2 meals a day, an avg of 17:7 fast/eat window - it's been 45 days.
45 days ago - 212lbs , 5'10" male 43yrs old
Today - 189.5lbs , I'm still 5'10", I'm still male, but 2 months older.
22.5 lbs of dropped water, and fat and whatever else - in 45 days ( 1 month and Half ) by eating 2 meals a day with virtually no snacking and only water and coffee!!!
I have high percentage dark cocoa chocolate 70% and higher with natural peanut butter sometimes when I'm hungry in between meals. I add sweetener to my coffee with heavy cream every day ( the sweetener is awful for me but I'm sugar addicted and thought to tread carefully here, and so I still have some sugar.) When I really feel I need it ( which is rare ) I'll have processed carbs like an occasional cookie, or slice(s) of bread. But much much much less than before.
I have hypothyroidism, and take a pill every morning.
I've done a couple 24hr fasts in my 45 days.
IVE LOST 22.5 POUNDS IN A MONTH AND A HALF. - after eating terribly, absolutely terribly for the last 2 years ( was going through personal trauma and ate for dopamine hits.)
A reversal this quick, by ......
1. Skipping the most important meal of the day ( sarcasm ), 17:7 fast, eat window
2. Consume less sugar and refined Carbs by approx 80/85%
3. Eat delicious, real, whole foods ( not processed ) from the earth. Steaks, chicken, salmon, Brazilian nuts, rainbow of veggies, fermented foods. I take occasional fiber supplement , the only supplement I take called Inulin.
4. Respecting the process. At first I indulged in more sugar and carbs. Of course I did. I had been my whole life 43 yrs. I'm a food junkie. So I reminded myself to be patient. When I stumbled, I would assure myself that till the next meal I would commit to staying clean. Patience.
5. I have to include Marc Sisson. I read 2 meals a day before Obesity code - and Marc and his Co writter were the first to make me believe that I could do this. And I have. I did it.
There were some bumps in the road of course, but I stayed on track. Now, when I feel pressured to eat something I don't prefer to put in my mouth ( I.e your invited to someone's home and don't wish to be rude ) I say fck it, and I eat whatever I want, KNOWING, that I'm armed with fasting in my arsenal. So I indulge and fast away my indulgences within a couple days!!!! Metabolic Flexibility is the name for that !!!!!!
Hey you don't believe us?? Just try it.
Goodluck
Thanks for sharing.
noom is garbage
Wow… I am a huge fan of yours now!!! You are speaking my language! Not from a vocabulary standpoint, as I had to look up about 14 words from your presentation on a different channel, lol, but from a genuinely intelligent and inquisitive human whom simply wants to empower others to take back their lives from going down the wrong pathways. Love and health to you good Doctor! You are a blessing. You remind me in looks and demeanor of my Mom and Dads Cardiologist Dr. Brian Donahue. He’s a great Doctor as you are and I wonder if he knows of you. I’m going to ask him next time I take my parents to see him. He’s from the Pittsburgh area UPMC.
Thank you. We (my husband and myself) followed The fast 800 diet for 12 weeks (we'd been Intermittent Fasting for 5 years) and I dialed myself back from DT2. We both lost 2+ kilos. We both lost belly fat and centimetres. It takes commitment and is not cheap. Carbs are cheap and quick to prepare. I have an auto-immune disease, on steroids, fatty liver, so still struggling with obesity.
What about all those POOR drug companies. If people begin to improve their health with healthy food those poor companies will lose revenue!
My French doctor here in France has not caught up with the low carb research. I hope he does one day. He still believes fat makes us fat and he's not an old Dr.
Calorie excess makes us fat. Not 1 particular macronutrient. U can lose fat by eating carbs or fats or anytjing. Just be in caloric deficit
👏 brilliant explanation
Whenever I feel like eating snacks I always turn on to Fungs' video and listen to his talk on junk food and how they spike bsl. Thanks doctor
Interesting fact: in bodybuilding, immediately after weight training, for muscle building purposes it’s beneficial to drink fast digesting protein along with insulin spiking sugar like dextrose. I used to do it regularly, never gained weight but gave me cavities so had to switch to an alternative.
In order to remain anabolic, the general idea was to eat slow digesting protein along with low glycemic carbs/fat throughout the day. Noticing where your body puts what you consume matters for results.
Dr. Fung keeps it simple ,and it works .
RIP Dr. Hallberg 😢🙏
She was an amazingly brilliant physician who helped so many people with her groundbreaking work.
Indeed
This was such an interesting and informative discussion. Thank you very much.
All roads lead to.......quietly dumping sugar from your diet.
and bread and veg oil
Years ago I remember reading in fitness magazines, “ If you switch from an automatic transmission to a standard transmission, you will loose 10 lbs. in the course of a year! 😀 I switched from an average of 4 cans of soda to 4 cans of diet soda a day, and after 1 year lost 0.00 lbs.! Cut 600 calories a day - zilch!
cuz calories are a hoax :D
That is what I've always thought! How sad when people that work in Health care look sicker than me! So how are they going to help me? Great video! 💞love you both!
I am a registered dietitian ; I can tell you in our profession; people believe IF and time restricted eating is extreme. No what’s extreme is 1/3 people obese, 1/3 people diabetic That’s extreme!!!!
The dietitians who seem to get time by the media all seem to advise people to eat lots of whole grains, fruits and vegetables, and reduce the fat consumption. That has not worked since the first time someone said to eat more grains and yet dietitians continue to say it. Why?
Dietitians promote a varied diet focused on protein, vegetables, whole grains, beans, nuts, seeds, olive oil, avocados and some dairy products. They emphasize whole grains as a healthy part of a diet which is true, we work directly with the public and often find they are consuming way to many processed foods, fast foods etc, so dietitians who get media time give a good I sight to a healthy diet, a varied unprocessed diet. They/we recommend whole unrefined grains like oatmeal, rice, whole grain breads and pastas, and if a balanced you can consume those foods; take a look at the Mediterranean diet. Thanks.
Insulin made my Mama worse sugar wise and weight gain when she struggled to begin with. She went down hill quickly once she was on insulin!!😪
I love to listen to this knowledgeable and pleasant person. I very much love your podcast also
I was hoping to hear a discussion about uric acid .. Dr Perlmutter's new book "Drop Acid" and Dr Fung as a nephrologist would both know a lot about this interesting new hypothesis. Ditching fructose is the key once again.
Dr Fung, thankyou so much for the work and the education! Question: in your description of old school calorie counting paradigm - you talk about the drop in metobolic rate as causing "a constant feeling being cold" as an indication that it was perhaps a short term solution that will be short lived. I gave up bread, most processed foods and most sugar... I am doing 16/8 plus occasional 2 and 3 day fasts, but I am definitely not dieting or restricting calories .... and I've lost 60 pounds in 6 months 🎉
I exercise at least 60 mins almost everyday (in fun ways)..... However I must admit I am cold all the time. ❄ I can cope witlh it easily with warm clothing.... it's much better than being too hot! But your comment has me worried. Does being cold all the time indicate something negative about my weight loss process or the speed that I lost it??
Dr Fung is right. Context and amount matter. I have a half cup of blueberries or blackberries with my unsweetened full fat Greek yogurt once or twice a week. That's good, I get vitamins, fiber and variety in my diet without too much of a carbohydrate load. Drinking a lot of juice or several bananas would be different.
I squeeze a little bit of lemon juice in my yogurt.
The low fat yogurt is garbage
@@kareenodum1734 I said full fat unsweetened Greek yogurt. Where do you see me advocating for low fat yogurt?
@@Kyarrix Sorry must have miss read it. Thought it read low fat.
Great interview with Dr. Fung! Thank you!!!
A great podcast that explains a still misunderstood problem.
You guys are awesome thanks for sharing your knowledge you’re both great speakers. I am learning a lot. There is so much more to learn.
When I went through college of medicine, we sure did not learn anything like this. Your talks and podcasts should be requirement in medical school. We have not been practicing medicine and just like you said tx sx not the disease. I wish I had known as 20 30 years ago.
2 of my favorite doctors ❤️💪💪
by listening to dr Fung adviced, I managed to reversed my t2d with 7 a1c to 4,7 a1c in 8 months and lost 20 kg.
Thank you, dr Fung
I have been struggling with Diabetes for 30 years, I now do intermittent fasting 16/8 and I am in Mounjaro ,trying to do better,riding my recumbent bike 4 miles a day, three times a week, thanks for sharing
Hi! Kudos to you to start intermittent fasting. Have you check out dr fung channel. I came across dr fung channel by accident and followed his tips and advices I lost 17 lbs in 4 months. If you read the comments from dr fung channel you will see people with diabetes were able to reverse their diabetes and get off their medications. Good luck!
Thanks !!!! 50% over weight by 2030, YIKES!!!! Excellent information
Interesting discussion
Thank you!
Conny from Sweden
Reading 'The Obesity Code' changed my life. Big Jason Fung fan!
The words shared are very meaningful and sincere
I’ve been fasting clean for a little over a month. Had a 20 oz Coke Zero and the flood gates for sugar cravings soared! I have to be very careful with artificial sweeteners as much as sugar.
One, of many, problems with sugar addiction, anything sweet tasting triggers it! I’m trying to cut all sweet tastes, but it’s tough.😢
Excellent interview. Thank you!
Thank you! Dr Fung makes sense to me.
Great information and conversation! Thank you!
Thanks doctor for videos that give alots information about type 2 diabetes
WOW Great and wonderful and useful Information I told my doctor About this he was against this he is no longer my doctor I am loving IF….Thank You Dr. Fung..I will be checking out your Channel, Dr. P.
such a clearly spoken podcast. I understood it all. Everything made sense. Thank you both.
Great information on getting better health.
Good show, I'm a subscriber.
💚🏜 so awesome to hear a fresh discussion from two of my favorite doctors!
Hello, I need a little guide here, My Dad is already doing dialysis. How can I improve that condition if the damage is already done? I changed my lifestyle 5 years ago, but I couldn't change his because we are in different countries at the moment. I just wonder if at this point is something that can be done to improve his condition
11:59 : similarly reducing a fever with acetaminophen can make an infection worse.
As someone who does a lot of research on nutrition, this is very interesting. What I am wondering is, is there any research on ketosis lowering insulin resistance?
Yes , that’s one of the mechanisms of ketosis is not needing higher insulin levels to put glucose into cells . You use an alternative source of energy called Ketones that doesn’t need insulin too much at all . It helps one pull out fat stores too to use for energy & lose weight & defat one’s liver .
And these lying doctors gets a nomination every year, while the Honest doctors like Jason and a few gets laughed at for speaking the truth. I’m 48, fasting, and never felt better. Give these gentlemen a nomination!
I like to listen to people who changed my life for the better.
Excellent discussion
Could have addressed correct foods that work best. Address issues for vegetarians and what works for them
I eat whenever I´m hungry, but I don`t eat sugar for decades and no bread since 12 months ago, the main meals are lot`s of vegetables (up to 1 kg/day) with meat and oliveoil, no carbs...in the morning or between some oats with apple and curd cheese and/or fatty yoghurt, in summary mostly ~ 150g oats/day in ~ 3 portions, (= 25 -30% carbs ) with veggies I estimate ~ up to 40-45 %....I don`t expect any substantiell bloodglucose spike and fat storage ever from ~ 50g Oats buffered with fat/protein.... lost a little weight, 61 yrs 71kg, BMI 20,7
I don`t eat any processed food/carbs...and oats are much cheaper...
Some other opinion I heard, by consuming carbs, processed and/or in higher quantity you better do intermed.fasting. We burn some 100 kcal/hour, every excess goes to body fat, by slow impact of low glycemic load and muscle activity there is no excess. Of course, if your "snacks" are 600kcal pure crap...some 450kcal goes to fat storage.
Two of my favorite doctors
they the food industries that pay for studies demonized the wrong fat , they never demonized seed oils or Crisco and margarine.
I appreciate everything mentioned but we keep focusin so much on obesity. My family has too many normal bmi relatives who are prediabetic or are diagnosed w diabetes. Can you please touch on what’s happening with them and their bodies? Most do not workout or control their food intake. They believe because they have normal bmi or are skinny they are blessed… despite the diagnosis
Exactly!
It’s still their diet. Some people just don’t gain the weight.
Some cultures such as Asian and Indian .. have lower thresholds to insulin resistance. Even though they appear to be thin .. they have higher rates of Diabetes. The fat % in their bodies may be the same as someone else .. but because of this lower threshold to insulin .. they are more prone to Diabetes and other illnesses that stem from it. As a result .. their diet (predominantly high in carbohydrates/glucose) perpetuates this huge problem. Dr. Nadir Ali, Dr. Ken Berry and I believe Dr. Jason Fung have videos explaining this. India and other Asian countries have the highest rates of Diabetes in the world. I’ve heard it called “skinny fat” ✨
@@Ingridvieira310 I am Asian and a lot of family members now reaching their 40s are prediabetic. My question is very personal unfortunately and I refuse to believe it is solely genetic. I think we also feed ammo into the gun/disease. Genetics is the trigger
@@paprichaat5 hi Mama Baba .. I would suggest listening to Dr. Nadir Ali videos on Personal Fat thresholds. It will answer your question completely. ✨
Dr. Fung's book, "The Obesity Code" is an incredible compilation of current science and lay-person friendly explanations of both obesity and type 2 diabetes. Thanks for this informative interview and discussion with Dr. Fung. I bought several copies of his book and gave them to family members a couple of years ago. (Retired Internist here.) :)
Angel of nutrition
Very good lecture I could say. I would just add the knowledge that each one has their personal fat threshold and each one has their own insulin grade of secretation genetically determined. Thats why 2 people eatong exactly the same food and doing the same things may gain fat diferently
Fructose... Guided missile...goes straight to the liver. Loved that!! 🤣🤣
Hospitals, doctors offices and schools should be places where good nutrition is taught and provided not places that contribute to disease and obesity. It is crazy the hospitals are feeding people the very food that caused the heart disease, high blood pressure or cancer that they are treating. Every person in the hospital should receive some nutrition education before being released. Every doctor visit should be an opportunity to educate patients about how food choices impacts their health outcomes. The fact that doctors do not get nutrition training as part of their training makes no sense. Medicare and Medicaid should require nutrition education as part of patient care. Focus should be on food choices. Fasting should be investigated as a treatment for disease.
What if I don't like fat or animal food, is eating beans and lentils and brown rice and fruits and vegetables good? I've been running on these foods only and I don't see anything wrong
Then keep going. Your health and well being take precedence no matter what anyone on the internet says.
Excellent video, very informative. Blessings from Puebla, Mexico.
Does food aroma help with satiety? I’ve been doing real food and eschewing processed food since the beginning of 2023. I’ve noticed when I cook with ghee and Asian sesame oil, the aroma seems to make me feel a little fuller before eating.
Dr. Fung, WHO (and when?) originally came up with the concept /practice of prescribing insulin to treat high insulin ? (at about 10 minutes into the video)
Probably those that treated type 1 diabetes in the past with it, and type 2 was similar in symptoms.
I would love to hear Dr fungs view on the book ( mastering diabetes). They have been curing diabetes on a high carb, low fat diet
High in starch and fruit
Last night I had strawberries after dinner and now blueberries after lunch. Yum
I purchase them frozen to ration them sparingly and reduce spoilage.
My problem this week was making whipped cream; I went thru 2 pints of HWC and gained a few pounds.
Lesson learned
For me, the cream is not an issue, fruit makes me gain. Fructose is a bad thing in my world. Sets off a spike that in turn creates other reactions.
@@gailstrickland221 it can be easy to drink your calories, they don't trigger the same satiation as solid food. I sometimes have full fat milk fortified with extra cream after exercise but it can be easy to overdo it.
Dr u r the best 🌷🌷🌷🌷
It's so hard to watch what you eat, & calorie control when there's a fast food restaurant on every other block, everywhere you look!!
Brilliant talk!!💐💐thank you!
What about blue zones that are high carb low fat diet
In the UK insulin is often given to type 1 diabetics where's as metforman is given to type 2 diabetics.
Metformin does not put on weight.
Does anybody know if it's okay or bad to have Metformin for type 2 diabetes?
Metformin seems to get the go-ahead by low carb proponents if your blood sugar is still high when diet is improved. It boosts insulin sensitivity instead of increasing insulin.
Dr Fung is a bonafide legend. Go watch all his lectures, take mental notes and try to understand your basic engineering. You owe it to yourself.
Great video! But what is that clicking noise??
Sure seems like Health Insurance Companies and Medicare would be receptive to a WFPB vegan message.
It would save them money on health care costs. This could off set the lobbying by food manufacturers.
Maybe educating health Insurance Companies and Medicare administrators should be a priority.
Health Insurance companies might even push doctors to take nutrition more seriously by paying for nutrition counseling of patients.
Most health professionals don't think, they memorize and repeat
This should be everyone's healthy living lifestyle. If you don't cut out ALL SUGARS and things that convert into sugars, don't do long term intermittent fasting of 16/24+ hours which is the most important recommendation on this list or don't get enough good sleep (don't eat past 6:00pm) you will not lose the bad fat weight nor gain the good muscle wight effectively, nor create a healing environment for the body to heal itself because you're limiting the bodies ability to produce HGH which helps make testosterone which does all sorts of wonderful things in the body. When I eat I eat high good fatty meats like a good 6oz rib eye steak with all the fat, whole eggs, fermented foods such as kimchi, butter, uncurred bacon, salmon, sardines, oysters, avacado, cheeses, healthy oils like olive healthy nuts like Almonds, Brazil, Chestnuts, Brazil, Hazelnuts, Macadamia nuts, Pecans, Pine nuts, sea salt, and if I'm in the mood for plant based foods I make sure they are of the cruciferous variety. Also the introduction of Boron in your diet also helps with the production of free testosterone along with, chlorella which is a natural algae that is purported to remove heavy metals and toxins from the body, along with Zinc 50mg, D3 10,000 iu, Magnesium, Niacin and maintaining a good gut flora with probiotics. I add additional vitamins such as trace minerals in my diet if I find I'm deficient in any one in particular.
The point about diet soda causing weight gain makes total sense. I didn't drink diet soda for two weeks and I had no cravings for junk food and I felt so much leaner after such short period of time. I really should quit drinking it once and for all.
I love this conversation, However I started keto & IF in Aug thru Thanksgiving, never lost a lb., so I switched to ADF & black coffee, for 6 weeks, never lost a lb., after Christmas moved to high fat keto with zero sweets, & gained weight. Please help I'm so frustrated
Have you got your hormones check? I was in the same situation but it was my hormones. Cortisol was high, progesterone was low, so no matter what I do, I would not lose weight. This is something that is happening and not really discuss. Now, I got my hormones align, I am finally losing weight with IF and Keto. I hope this help.
In this world we obey the laws of thermodynamics. Although hormones affect how efficiently we process calories, ultimately you need to be in a calorie deficit to lose fat. Fat is 9 calories/gram. Adipose/fat tissue is 87% fat/lipid. You need a 7800 calorie deficit to lose 1kg of body fat. If you have not lost weight, you have not eaten little enough for a long enough time period. If you want a hack or an excuse then blame hormones, bad luck, genetics or being a special snowflake. If you want to get what you always wanted, count your calories, accept that this is very tough and will take time and determination.
@@jackglass9226 I participated in Optivia or formally known as medifast. Counting calories will work, for awhile, until your body continually adjust to the lower calories, then you gotta live on 5-600 calories, which is not sustainable
@Petricia Hice I'm currently maintaining 13% body fat on 2200 calories. I have never heard of anyone neededing as little as 500-600. Could you explain with what mechanism your body is adjusting your caloric output to be so low? Your caloric output is made up of your base metabolic rate, thermal effect of processing the food you eat (0-3% for fat, 8-12% for carbs, 20-30% for protein), thermal effect of exercise and non-exercise movement thermogenesis. Those with severe metabolic disorders may have a 20% reduction to their base metabolic rate. Even if you have hashimotos, weigh 50kg, eat only 500 calories, and lie down in a dark room not moving at all for 24 hours that would give you BMR of 900 and TEF of 50 giving you 950 calories used for those 24 hours. Please show your math :)
@@jackglass9226 medifast or Optivia, uses 1 meal & 5 fuelings. The 5 fuelings are 100 calories each, your 1 meal varies, but very low fat & low carb. So it's around 4-500 calories. Most time averages 900 to 1000 calories a day. Eventually your body adjust to that calorie count & you stop losing weight, so you have to continue to lower those calories. Finally I realized Its
unsustainable.
I read some of this book in March and had an endocrinologist appointment in May. I've lost 10 pounds since mid May '23. Calorie counting has been a huge lifestyle change for me but my doctor recommended an app called LOSE IT. It's truly an incredible tool - calorie counting. I used to think it was tedious but after being told I was prediabetic with another underlying health condition it was time to make a change. I'm going to complete the rest of Diabetes Code too.
I have used that app and loved it. I like reporting everything I eat because it makes me cognitive of what I'm eating. I count total carbs, fat and protein.
@@90secondsuntilmidnight Yes! Exactly:) now it's 25 lbs. I just keep losing
My grandmother died 103 with type I since age of 40, never had any insulin injection, never had more than 1.00 glucose in blood, she managed it with artichoke and topinambour, she took metformin I think, that's all. She basically had zero insulin in her blood, so insulin is optional. She looked obese, but I realise today that she was metabolically healthy.
Metformin is medication for diabetes.
@@judithhopes151 a low dose of this might be included for healthy people to slow down aging.
I doubt she had Type One Diabetes but she had Type Two - otherwise, she would lose weight & her muscles would waste away. It causes organ failure , blindness , losing one’s limbs & death without any insulin being available in one’s body made by the pancreas . Metformin is for Type 2 Diabetics .
@@heidivernathorbjornsen475 while she lived 102 I never saw a blood test with other than zero insulin. She was functioning like that. I don't know if she had type I or II buy anyhow her pancreatic head islets of langerhans did not show trace of its presence in blood tests. She always was mild obese and always had the mindset of a tank.
Dr Jason deserves the utmost respect because of his honesty....of course the drug companies hate him
He is a visionary
what about leptin? what about people who have type two who are lean?
You mean TOFIs, Thin On the Outside; Fat on the Inside? It's the excess visceral fat that is killing us
If you have t2 you have liver fat, and fasting will increase your lean tissue.
I lost 10 pounds in 2 months very comfortably without feeling extreme hunger and fatigue thanks to intermittent fasting and low carb diet style. It’s a part of my life now. I hadn’t been able to lose these 10 pounds for three years.
I was hoping to hear some focus on the role that uric acid plays in all of this. After all, Dr perlmutter did write the book Drop Acid.
I watch net carbs of GREAT food and am starting the fasting. Process. I a, really feel😮ng good. Today I am at 16 hiyrs..not a lot but busy and ok. But I had a big meal at midnight because I was busy. And I had a steak sautéed mushrooms and egg. And some milk poured whole milk. Thank you. And I went to sleep but I got up this morning and I am feeling really good and it’s now about 3 PM and I will probably do a 20 hour fast and then Nibble on some good stuff and feel better. And maybe take a nap which sounds good.
This was years ago that I don’t even want to tell my PCP what hurts otherwise I will have like 10 px after. Everytime you tell him something he has tons of different px for it. He has his px pad with him all the time.
For weight loss, a few zerocarb days a week works great. So does a few days with no food, but the amazing thing about fasting is all the health benefits! Some of the many benefits of doing occasional extended fasting: Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body. Blood pressure is quickly and dramatically lowered. Fribrosis/scarring is reversed over time and telomeres are lengthened, which also helps with lung fibrosis. The hunger hormone ghrelin lowers with extended fasting and rises from dieting. Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy! Fasts from 36-96 h actually INCREASE metabolic rate due to norepinephrine release! Reflexes and short term memory are increased.
Thymus is regenerated, which suppresses aging and renews the immune system.
Fasting increases nitric oxide.
Fasting stimulates phagocytosis, the ingestion of bacteria, plaques and viruses by the immune system.
Weight loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods.
Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus.
Losing weight through intermittent fasting shows greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period.
When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state.
What breaks a fast? Anything with protein or carbohydrates in it will break a fast, though if the amount is tiny you will go back into ketosis very quickly. Most teas and herbs are OK. Most supplements and meds will either break ketosis directly or contain a filler that will. Many medications are dangerous to take while fasting so you may have to talk to your dr. about discontinuing them during a fast.
Fasts of several days will not affect short term female fertility and may increase long term fertility, especially in women with PCOS.
Does fasting lower testosterone? No, it raises it when the fast is broken by increasing lutenizing hormone and helps build muscle by increasing insulin sensitivity!
The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again!
Does the body preferentially prefer glucose as a fuel? No, your body always runs mainly on fat except for brief periods of very intense exercise. Your brain also prefers to burn ketones at a rate of around 2.5 to 1 when they are available in equal quantity to glucose.
Fasting stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses.
Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more.
It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention!
Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers.
In fact, the biochemical regulator of BDNF production is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting.
Fasting also increases telomere length, negating some of the effects of aging at a cellular level.
A fasting mimicking diet for 3-5 days in a row also provides many of the same benefits as water fasting. FMD usually has 200-800 calories, under 18 g of protein and under 18 g of carb.
Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia.
Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or certain forms of hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution as it could lead to ketoacidosis. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

Calorie counting is a myth, yet 100% of the time when they test it in a lab under controlled conditions, it works perfectly.
But who lives in a lab and how long is the lab residence, 5 weeks, 5 years?
@@anomarnamloh7444 There is only so long you can conduct metabolic ward experiments as they are expensive. People aren't going to stay there unless you are paying them well. However no matter who they bring in. No matter what health conditions they have or they are perfectly healthy. The law of CICO applies and works perfectly 100% of the time when tested. IT is amazing what happens when you measure things accurately and even more so when people are unable to cheat.

Love this conversation but not eating fruit to loose weight seems....off. Most doctors suggest a clean diet of fruit and veggies
Most doctors got one day's worth of nutritional training and it probably happened 20 years ago. They suggest what is basically considered common knowledge instead of modern science. Apple juice is just as bad in every way as drinking soda.
