Dr Feng idiots at VA wanted to give me insulin with my T2. Told them to stuff it. They think that most veterans are morons. Knew that I already was making insulin and had insulin resistance. The VA uses the ADA diet(keeping Veterans in T2 mode). Assuming they are getting kickbacks from Govt, ADA and drug companies. VA doctor got angry, I was doing fasting, keto/carnivore. However, it lowered my A1C. I did my own personal study, ADA diet raised glucose a lot. Reversed it when I did fasting and keto/carnivore. They hate that I reversed it.
I began volunteering at my local food bank, and this lecture immediately came to mind. Everyone is overweight, and the main foods offered free to our community are starches. Any fresh produce, meat, or eggs is strictly limited to one item, whereas things like baguettes from a local bakery are available in unlimited quantities. It's also a lot of canned foods, dried beans, peanut butter, cold cereal/oatmeal, and sweetened yogurt. Even people who were alone in their household got a huge bag of baker potatoes and huge onions. Other bakery items are plentiful as well. While they wait, snacks are offered, usually mini muffins and cookies. So, I'm here reviewing this information, so I can apply it to what I see at the food bank. Poverty and obesity go hand in hand. That's exactly what I've been seeing.
nunya inct probably not well educated, especially in nutrition, money management, childcare. I always believed these should be compulsory in all schools. We don't have that much in Canada
Nonmi Hiseddeo exactly. A local family ran our food bank. All 4 of them were morbidly obese. Some people commented that they must be eating all the food at the food bank. I explained that no, they were probably subsisting on potatoes and bread😞
Thanks Eddyabby. I'm glad you are enjoying the series. I agree with you completely. Interesting how we are always looking for the real culprit behind obesity, and it turns out to be the farm subsidies and government sanctioned dietary advice.
Thank you for this series, Dr. Jason Fung - I wish to express my respect and gratitude. (BTW, the above lecture is blank after 57:22 when you ask for questions. It is about the only improvement I would like, it will start #3 more quickly if the blank spot is edited out. :)
Absolutely saving my life. In alcohol treatment centers they have psuedo educational programs. This is both useful for craving in alcohol and carbohydrate abuse.
Overeaters anonymous used to have slogans like don't eat whites.sugar processed white bread. Three meals a day life in between. My brother back in the seventies was put on a low carb diet. Odd that that was disregarded
polly jetix so the rest of the globe is watching this video and it must be 0% Americans. I guess the population of the world is only 300k people outside of America! Wow, the more you know.
Great information....I was diabetic with AC1 over 10.5. Tried fasting and reduced my processed foods and I am no longer diabetic ..thank you for making this happen and no longer taking medication or insulin ...
wow 10.5, glad it's come down! Some of the many benefits of fasting and a lower carb whole food diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data: The hunger hormone ghrelin lowers over time with extended fasting and rise from dieting Thymus stem cells are regenerated, which suppresses aging and renews the immune system. Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system. Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic. Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque. 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 clotting is reduced and blood clots and arterial plaque are reabsorbed into the body. Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy! 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. Fasts of several days will not affect short term female fertility and may increase long term fertility especially in women with PCOS. It's absolutely fine for cortisol to be high while fasting, because it produces sugar from fat instead of lean tissue ruclips.net/video/giEDadzoErs/видео.html Does the body prefernetially prefer glucose as a fuel? No, it never uses mainly glucose for fuel and using glucose for fuel is very biochemically damaging! ruclips.net/video/Nf1jwMbvNxw/видео.html 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! Is fasting just the same as caloric restriction? No! Dieting increases the hunger hormone ghrelin while fasting decreases it and has many other health benefits! ruclips.net/video/sVl-nilhWLc/видео.html 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. It 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. Does fasting burn muscle? In most cases no! ruclips.net/video/teQIaU6wp2o/видео.html Fasting can make you gain muscle faster: ruclips.net/video/5RM8GRzsIIg/видео.html 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! Fasts from 36-96 h actually INCREASE metabolic rate! ruclips.net/video/BeC_gIR2Z14/видео.html Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections. After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system. When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging. 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. Autophagy induced by fasting even helps hair regrow. What breaks a fast? ruclips.net/video/7aRLsCpxy3o/видео.html Dieters losing weight through intermittent fasting show 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. Does fasting lower testosterone? No, it raises it and builds muscle! ruclips.net/video/fJUDucBWv4s/видео.html Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks. Fasting also increases telomere length, negating some of the effects of aging at a cellular level. Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly. 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.

Most people are far too lazy to listen to science. They would rather watch American Idol or Desperate Housewives. I have never seen even one minute of either.
After watching one of his videos I started intermittent fasting right away, 5 hours feeding and 19 hours fasting, didn’t have any problem. I lost 13 pounds in 2 months and my blood sugar is in the high 90’s compared to around 200’s before. I have more energy and feeling great. Thank you Dr. Jason Fung.
When is this going to become mainstream? This should be a national (international) priority. It's clear the obesity epidemic is not being addressed seriously by the received wisdom methods. The science needs to win.
This makes so much sense. I was in the Navy for four years and everyone comes off of their deployments thin and fit. We have the ability to eat whatever we want while on deployment but there is always that 12hr window of fasting. The last meal of the day is at 5-7pm-ish and the first 5-7am-ish.
If government really cared about the health of its natural citizens instead of just its corporate ones, it would eliminate all corporate welfare subsidies. Then it will be cheaper to buy the locally produced fresh foods. And everyone will be healthier. Including the military forces.
Been binge watching these videos and love them. I'm a nurse and feel like I never REALLY AND TRUELY understood type 2 diabetes until I listened to Dr Fung. These should be mandatory in nursing and medical school
I have COPD and have been fighting with prednisone for 2 years. I'm finally weaning myself off it and would love to lose the weight it has packed on me. Fasting is easy, so is avoiding sugar, bread and processed foods. Nothing happening with my weight yet so hoping the smaller dose of prednisone will fix it. Blood sugar is up, that is why I started fasting.
Dr Jason Fung is really saving lives through this wonderful insight into fasting. I don’t know where I have been all these years. We are praying for you Dr Fung. sarah UK
Not just the food. I have left ads of stress and worry everyday and I am still diabetic even though I followed all the advice . A bad souse is just as bad for insilin
And cortisol ... it sends you haywire and noone knew it. Add babies (which apparently forces insulin resistance) then menopause and your doomed and left feeli g like its all normal and your own faulr. So why isnt all the true scuence available being imolemebted. Clearly doesnt suit someone.
I always liken it to the Coca plant... Where the Coca plant grows they drink it as tea and use it medicinally, but when refined becomes a highly addictive drug!! Same concept for Carbohydrates!!
Very true! A friend of my parents went to Bolivia many years ago to teach people how to build houses out of concrete. He spent a long time there and used coca leaves every day. He said that it was like coffee, you felt a little less tired and a little less affected by the high altitude from it but there was no withdrawl like with coffee once he left the country and stopped.
Thank you for your videos. You inspire me so deeply. Your work should be mandatory learning for premed students. I'm learning how to be healthier every day and finding you has changed my life and the lives around me so much better. I find myself giving family and friends recaps of what you are teaching and it blows their minds. Thank you from the bottom of my heart and pancreas. Thanks to you I'm giving my pancreas a well deserved break from manning my fat reserves.
I'm type 2 diabetic and was put on insulin last summer. Since then I've gained 40 pounds. A co-worker recommended Dr. Fung's book. I am anxious to read it and to see if I can control my diabetes with a change in diet and to get off this awful insulin.
Not good. I'm off insulin and losing weight because of that. I still have not started a ketogenic diet. My blood sugar is stratopheric. I have no one but myself to blame. Just can't get in control of my eating. I'm hoping to complete a 36 hour fast to maybe kick things off.
*pinesiskin59* : Fasting can be tough when you're not used to it. Instead of doing a 36-hour fast, try cutting out one meal a day, so that you have at least 12 hours between two meals. Your body gets used to this new eating pattern without too much trouble after which you can reduce your eating window to 10, 8 or less hours. This measure alone is going to dramatically improve your metabolism. Nevertheless, you need to keep in mind that any kind of a fast remains very challenging as long as you don't cut down on the carbs in your food. If you combine fasting with LCHF, it becomes "a piece of cake": no cravings, no hunger ! 😉
Like the other commentator said, start slowly maybe just cut out breakfast, then after a week breakfast and lunch... Also, I would not go past 24 hour fast, unless you plan to fast longer than 2 days. I only say that because Dr. Fung himself said there is no point of fasting for the 2nd day and stopping because the 2nd day is the hardest and than it gets easier.
Hawaiians too, as soon as they stopped growing their own food and bought their spam, corned beef, crisco, bread, etc from the stores, they got very fat and unhealthy. Westernized food changed their lives forever. Many of us are now diabetic.
Thanks Jason. It's great to hear this information from the scientific/medical standpoint. I had a bad case of insulin resistance. Now, I have lost over 100 lbs thanks to a low refined-carb diet with a lot of healthy live and whole foods, no flour or sugar, and intermittent fasting. I learned this healthy way of eating in a 12 step group for food addiction.
Dr Jason Fung work Is seriously underrated. All you see are a bunch of RUclipsrs who plagiarized his work on fasting, without giving him a good referencing.
My bloods was very good my nurse said 8 .3 she said I see your staying below 10 I feel so happy dr flung been out walking all day my legs ache dr flung but am a lot happier not stressed out today thank you dr flung
EXCELLENT EXCELLENT breakdown of what, how, and why insulin works in our body. As a viewer, i was engaged and im walking away more informed and confident than i did 3 hrs ago when i left the American doctor office. I do 16:8 intermittent fasting for years now but i snack every 2 hrs for fitness goals as i thought. I just was told im knocking on pre diabetic doors today and i couldn’t understand HOW. Im slim and curvy. Your video Answered ALL my questions and i plan to overcome this within the next 90days. I even gave up meat 3mos and still insulin resistance issues. THANK YOU so much Doctor Fung.
I'm very very happy to hear the medical information relating to obesity, diabetes and insulin resistance. Really great medical knowledge for good health. It's really working.Thank you very much Dr. Jason Fung.
I used to just exercise my insulin resistance. Terrible way to go. Now I have pre-diabetic legs. I'm working on it now. Thank you Dr. It'll take a while I take it. one meal a day and high fat and protein low carb is definitely helping.
My mother is prediabetic. Wish she could understand this. I've been doing IF 18:6 and at times 24hr fasting. I'm going on 8 weeks and feel great. I lost 10 lbs and hopefully counting. I cut back on processed foods and sugary drinks.
Also, consume seasonal food. There's a reason why sweet fruits aren't available naturally all year long and are mostly in summer, so we prepare for winter. With modernity we can get anything at any time.
Terrific series , thanks Jason, this is so much more than what a documentary provides. Interesting that in the U.S. the rise in obesity in pets , glad you took time to address the farm subsidies and that the food important for us is getting very little to no subsidies. Insulin/insulin resistance leads to fat gain makes sense.
The Aetiology of Obesity Lecture Series are worth watching. It could be the most valuable 7 hours in my life. In your life too (if you struggle with diabetes)
But I wonder... what about mineral content of the diet? We know that Potassium, Magnesium, Calcium, etc. are very important in liver function, and in many other processes. And we also know that modern farming practices lead to mineral-depleted soils. As the soils are depleted, the crops grown on those soils contain less nutrition. Most Americans eat a diet far too low in minerals such as magnesium and potassium. What effect does this have on metabolism? Diet soft drinks are just as hard on mineral balance in the body as the regular soft drinks. The chemicals in those drinks leech minerals from the bones. Which could explain why non-caloric-sweetener sodas don't seem to help weight loss.
You can't really get much minerals from plants anyway, they are bound up in oxylates. They also unbalance your minerals because they have too much copper and too little of other things like zinc. Supplementing also causes problems. If you have some eggs every day your mineral levels will be fine.
@@LTPottenger , Why would u need to eat animals, birds, bird eggs, fish, dairy & oil to do this? U make no sense except paving your way for heart disease & cancer. U get all the vitamins & minerals & protein from a Whole Fodd Plant based diet. Read Dr. T. Colin Campbell's book, "The China Study"
This Aetiology of Obesity/Diabetes video series is very educative and explains what other doctors never explained, they just prescribed high doses of Metformin and Januvia outright.
Thank you, Dr.Fung! I have been losing and gaining weight since my teenage years. A year and a half ago, I lost the most amount of weight 45lb, but slowly gained it back. I would exercise more and more but made little difference. At the rate I was going, I would have to be at the gym all day to get the same weight loss results. I have been reading a lot about your Philosophy, and I'm going to start doing some intermediate fasting and document my journey. Kind Regards.
Spot on with insulin resistance. However....its not simply tolerance to inflated levels of insulin. The introduction of trans fats in huge quantities to society, replaced healthy fats. Trans fats, very elongated ....utilized in making up cell walls, instead of shorter chained fats...distort insulin receptors and glucose uptake. Insulin..not able to lock into cells, to facilitate glucose transfer...glucose levels do not decrease and the body spikes more insulin. Trans fats are a primary cause of type 2 Diabetes
Dear Dr Fung - I understand that obesity DOES drive insulin resistance , and with TOFI persons, a just little fat around the abdomen can do it, with fat in the liver and in the pancreas. This is the work of Prof Roy Taylor,Newcastle.2009 and now 2016 clinical trial DIRECT . HIs concept of the personal fat tolerance level. He has shown that reduction of fat can bring back good pancreatic function and lower insulin ' resistance' although there are still plenty of unanswered questions.
Yesterday morning before having any breakfast my blood glucose was 5.0 mmol. Without having a bite to eat I cycled 40km over strenuous hills and I checked my blood glucose level and it was 5.9 mmol. Goes to show that the body regulates itself to release glycogen when required. I did have something light after that but I had another 20km's to reach my car. The ride back was a bit tiring but manageable as I used a he as heart monitor to cycle within the green zone.
It seems to me that Type One Diabetes and Type Two Diabetes shouldn’t even have the same name. Please give us some advice on how a Type One Diabetic wearing an Insulin Pump can use Intermittent Fasting to lose weight.
We are a little confused as to the meaning of insulin sensitivity. At 33:40-33:54 Dr. Fung begins to say when you are sensitive to insulin you tend to gain more ...; then he quickly changes that to the insulin sensitive ones will gain less weight, but the insulin resistant ones will gain more weight. Shortly after that at 34:09-34:44 he says when you are insulin sensitive you gain more weight. Please clarify.
Steve Rush So let’s say two people produce the same high amount of insulin and eat the same amount of sugary food. The resistant one will spike their blood sugar, but the sensitive one will gain weight. The resistant one will not be able to store as much so they won’t necessary gain more - although they may already be obese.
Our goal has to be insulin sensitive because that way we gain less weight, our páncreas produces less insulin because we are very sensitive to the few insulin is up there. if you start to eat refines your body will start to produce more insulin and you become insulin resistant and fat
Hi Jason - I eat LCHF and have plateaued on weight loss. I eat once daily, at 6:30 pm, and fast the entire time in between 5 days out of the week. When I keep my sugar low by eating healthy vegetables (cauliflower, broccoli, green beans) I have a hard time keeping the number of calories up!! I add butter or coconut oil, but if I add too much I just can't eat it all (which is a very new problem for me, lol). I think my difficulty is that if I can't eat enough calories, I'm getting into calorie deficit because I'm getting full before I hit my resting metabolic base rate of 1,500 calories a day. Should I increase my sugar those days so I can meet the calorie minimum and just have more 36 hour fasts?
Dr. Fung's recommendation in this video is to eat within an eight to ten hour "eating window" so, perhaps, you should try eating two or three meals - the first at the beginning of the window and the last by the end. For instance, have the first meal at 10:00AM or 12:00PM and finish the last meal by 8:00PM. Personally, the last thing in the world I would do would be to eat a bunch of sugar just to get my calorie count up. Just adding 200 calories to your daily intake using sugar alone will require you to eat slightly more than four tablespoons of sugar. Yuck!
I agree-36 hour fasts are optimal. Sleeping on an empty stomach that second night leaves my skin glowing and my appetite under much better control-in fact I usually have to make myself eat when I wake up.
One more thing to Dr. Fung...Your content ends a bit before the video ends, so I had to manually skip to the end to view the ad and activate the ad revenue. Maybe you can add an ad right where the content ends so we can actually pay you back for all the wonderful, free advice!
Would love to see a debate between Fung and McDougal/Gregger/Esselstyn. Also, Dr. Walter Kempner was reversing diabetes and Kidney disease in the 1940s with white rice and table sugar. Would love to hear Dr Fungs opinion on that too.
Kempet diet was a starvation diet with around 1400 kcal, so yes you loose bodyfat and your insulin sensitivity increase, but is is not a long term solution :/ It musst be a lifestyle, OMAD works perfect for me
What's the point? They don't use science only weak statistics which they pretend is science. Same with drug companies. Real science is based on experiments and is essentially just fact. Your body works on chemistry not made up hippy garbage nonsense.
Dr. Jason, i don't drink coke or any sugary drinks. I dont eat chocolates, ice cream, cookies or cakes. The one thing sweet i take everyday is lil critters omega 3 which is a sweet gummy bear that is coated with sugar. Do you think this is the one that causing my paresthesia or peripheral neuropathy?
riccia888: I'm assuming your paresthesia or peripheral neuropathy is a continuing disorder and not something that comes and goes as you eat particular foods. I'm also assuming that it's probably associated with diabetes or prediabetes. Google Blood Sugar 101 and click on the top result to enter the website. Scroll way down near the bottom to the link, "Download The Lower Your Blood Sugar Flyer". The flyer is a one-page instruction on how to determine which foods cause you to have elevated blood sugar. The flyer will teach you how to know how to know so you don't have to guess any longer. Why don't you throw away the gummy bears and use an oil capsule for your omega 3?
Here is a question that I cannot figure out the answer to. If I fast and my Blood sugar goes up to 280 do I take insulin or not. I am confused between what do I do if my blood sugar will not stay down. I have lost 40 lbs but I worry when the blood sugar goes over 140. I have had diabetes for 40 years and I think the desire to stay between 90 and 140 is foremost in my mind. When I am unable to take insulin my blood sugar goes up. I eat twice a day and not much food, meat and no carbs.
Wow your explanation is awesome here. Thank you so much. I've followed you on DietDoctor.com for years, but never heard about how Insuline Resistance sneaks up on you over the years. Now I understand!! I was a thin child! But as the years passed, when we started eating our not Mother Approved food out away from home, I started to Plump up. Now I see. Wow. But your advice these days, now in 2019 has certainly changed, now you recommend a lot of FASTING and NO CARBS. That's a big change!
What do you eat though? Intermittent fasting is important but what you eat is also very important. Meat, eggs, butter, enough healthy fats, that means nothing out of a bottle, animal fats from sustainably raised animals, grass-fed grass-finished ideally.
But what do you eat for breakfast, lunch, and dinner to keep from being very hungry in between? I'm 59 and always had something to eat in between because I was always hungry. Note that I was always skinny. Even today if I have 2 eggs in butter with some veg for breakfast, i am really really hungry a couple of hours later. I wake up hungry. I don't eat much processed carbs. Blood sugar always seems to drop. I have no sugar cravings at all.
I’ve been trying a 20/4 intermittent fast the past week but did not lose weight. I’m not diabetic but I am pre-diabetic. How long does it take for the insulin resistance to correct so I can start losing?
Globally the poverty correlation falls apart since $30,000 a year is not poverty when compared to poorer nations, but is very true in the US since like you said corn and wheat is subsidized.
This thermostat effect is also happening in fasting. While you fast, you start not to lose weight but you must go on fasting not to gain again. It never helps to lose weight after a point especially for fertile women.
Around 30-35 minutes, I am a bit lost. Am I sensitive or resistant? Or I have insulin effect? It’s a lot of info... 3 hours of Dr Fung. I’ll take a break and come back to it later!
Ok, so I still need to know....are my Metformin and my Jardiance helping me reduce insulin resistance or not? They definitely help with glucose meter numbers, but I now see that glucose levels themselves are not the main issue.
This video needs to be updated with the new "overflow" paradigm instead of the "internal starvation" paradigm to more reflect what you are currently publishing.
eating during soccer practice makes sense from a performance perspective... but that's not snacking, it's replenishing energy stores. Kids who are just sitting around should not be grazing.

Dr Feng idiots at VA wanted to give me insulin with my T2. Told them to stuff it.
They think that most veterans are morons. Knew that I already was making insulin and had insulin resistance. The VA uses the ADA diet(keeping Veterans in T2 mode). Assuming they are getting kickbacks from Govt, ADA and drug companies. VA doctor got angry, I was doing fasting, keto/carnivore. However, it lowered my A1C. I did my own personal study, ADA diet raised glucose a lot. Reversed it when I did fasting and keto/carnivore. They hate that I reversed it.
Thank you so much! I really loved your presentation!
I began volunteering at my local food bank, and this lecture immediately came to mind. Everyone is overweight, and the main foods offered free to our community are starches. Any fresh produce, meat, or eggs is strictly limited to one item, whereas things like baguettes from a local bakery are available in unlimited quantities. It's also a lot of canned foods, dried beans, peanut butter, cold cereal/oatmeal, and sweetened yogurt. Even people who were alone in their household got a huge bag of baker potatoes and huge onions. Other bakery items are plentiful as well. While they wait, snacks are offered, usually mini muffins and cookies. So, I'm here reviewing this information, so I can apply it to what I see at the food bank. Poverty and obesity go hand in hand. That's exactly what I've been seeing.
Nonmi Hiseddeo So true
Nonmi Hiseddeo why does poverty and obesity go hand and hand?
Nonmi Hiseddeo .i could never understand why poor people in developed countries were so over weight until I started following Dr. Fung.
nunya inct probably not well educated, especially in nutrition, money management, childcare. I always believed these should be compulsory in all schools. We don't have that much in Canada
Nonmi Hiseddeo exactly. A local family ran our food bank. All 4 of them were morbidly obese. Some people commented that they must be eating all the food at the food bank. I explained that no, they were probably subsisting on potatoes and bread😞
Finally, a Doctor who has really helpful insight and advice and doesn’t just promote Gastric Bypass!!!
Thanks Eddyabby. I'm glad you are enjoying the series. I agree with you completely. Interesting how we are always looking for the real culprit behind obesity, and it turns out to be the farm subsidies and government sanctioned dietary advice.
Thank you for this series, Dr. Jason Fung - I wish to express my respect and gratitude. (BTW, the above lecture is blank after 57:22 when you ask for questions. It is about the only improvement I would like, it will start #3 more quickly if the blank spot is edited out. :)
Absolutely saving my life. In alcohol treatment centers they have psuedo educational programs. This is both useful for craving in alcohol and carbohydrate abuse.
Overeaters anonymous used to have slogans like don't eat whites.sugar processed white bread. Three meals a day life in between. My brother back in the seventies was put on a low carb diet. Odd that that was disregarded
My life is changing because of this information.
These videos are criminally underviewed.
yes we should jail those who dont watch these types of videos!
Because America gravitates to entertainment, instead of education.
polly jetix so the rest of the globe is watching this video and it must be 0% Americans. I guess the population of the world is only 300k people outside of America! Wow, the more you know.
Absolutely
Criminally
Great information....I was diabetic with AC1 over 10.5. Tried fasting and reduced my processed foods and I am no longer diabetic ..thank you for making this happen and no longer taking medication or insulin ...
Mario Chang hope you are still doing well. I recently started keto to get off the meds
How are you now
And how did fast?
A1C
wow 10.5, glad it's come down!
Some of the many benefits of fasting and a lower carb whole food diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data:
The hunger hormone ghrelin lowers over time with extended fasting and rise from dieting
Thymus stem cells are regenerated, which suppresses aging and renews the immune system.
Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system.
Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic.
Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque.
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 clotting is reduced and blood clots and arterial plaque are reabsorbed into the body.
Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy!
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.
Fasts of several days will not affect short term female fertility and may increase long term fertility especially in women with PCOS.
It's absolutely fine for cortisol to be high while fasting, because it produces sugar from fat instead of lean tissue ruclips.net/video/giEDadzoErs/видео.html
Does the body prefernetially prefer glucose as a fuel? No, it never uses mainly glucose for fuel and using glucose for fuel is very biochemically damaging! ruclips.net/video/Nf1jwMbvNxw/видео.html
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!
Is fasting just the same as caloric restriction? No! Dieting increases the hunger hormone ghrelin while fasting decreases it and has many other health benefits! ruclips.net/video/sVl-nilhWLc/видео.html
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.
It 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.
Does fasting burn muscle? In most cases no! ruclips.net/video/teQIaU6wp2o/видео.html
Fasting can make you gain muscle faster: ruclips.net/video/5RM8GRzsIIg/видео.html
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!
Fasts from 36-96 h actually INCREASE metabolic rate! ruclips.net/video/BeC_gIR2Z14/видео.html
Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections.
After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system.
When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging.
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.
Autophagy induced by fasting even helps hair regrow.
What breaks a fast? ruclips.net/video/7aRLsCpxy3o/видео.html
Dieters losing weight through intermittent fasting show 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.
Does fasting lower testosterone? No, it raises it and builds muscle!
ruclips.net/video/fJUDucBWv4s/видео.html
Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks.
Fasting also increases telomere length, negating some of the effects of aging at a cellular level.
Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly.
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.

He has 54,000 followers now (less than a year later)... a good sign :)

Most people are far too lazy to listen to science. They would rather watch American Idol or Desperate Housewives. I have never seen even one minute of either.
After watching one of his videos I started intermittent fasting right away, 5 hours feeding and 19 hours fasting, didn’t have any problem. I lost 13 pounds in 2 months and my blood sugar is in the high 90’s compared to around 200’s before. I have more energy and feeling great. Thank you Dr. Jason Fung.
When is this going to become mainstream? This should be a national (international) priority. It's clear the obesity epidemic is not being addressed seriously by the received wisdom methods. The science needs to win.
Jason Fung is THE MAN.
Dr. Jason Fung. You are changing my life in just 2 weeks. Thank you for taking the time to post these. I can't get enough.
How are you doing now
This makes so much sense.
I was in the Navy for four years and everyone comes off of their deployments thin and fit. We have the ability to eat whatever we want while on deployment but there is always that 12hr window of fasting. The last meal of the day is at 5-7pm-ish and the first 5-7am-ish.
John Smith and now the military are stressing the KetoDiet
yu
Yeah ..but you have to be thin and fit when you go in otherwise they don’t want you. Isn’t that right ?
Then why eat in the morning? Even Dr. Fung doesn't!
@@TheJeanette53 , true, they rejected a girl I know for basic training because she was overweight!
If government really cared about the health of its natural citizens instead of just its corporate ones, it would eliminate all corporate welfare subsidies. Then it will be cheaper to buy the locally produced fresh foods. And everyone will be healthier. Including the military forces.
Logan Quinn they don't care.
Yep they want us sick and fat
You are the man Fung. You are one of the few who deserve the title of doctor. Thank you for the incredible info.
Been binge watching these videos and love them. I'm a nurse and feel like I never REALLY AND TRUELY understood type 2 diabetes until I listened to Dr Fung. These should be mandatory in nursing and medical school
I have COPD and have been fighting with prednisone for 2 years. I'm finally weaning myself off it and would love to lose the weight it has packed on me. Fasting is easy, so is avoiding sugar, bread and processed foods. Nothing happening with my weight yet so hoping the smaller dose of prednisone will fix it. Blood sugar is up, that is why I started fasting.
Dr Jason Fung is really saving lives through this wonderful insight into fasting. I don’t know where I have been all these years. We are praying for you Dr Fung. sarah UK
How are you today?
These videos are SO important. The world would be a better place if everyone saw them.
WOW, you have opened my eyes. You are my hero!!!! 🙂
Long live Dr Fung! You've given us information for life. God bless you.
Poverty is stressful and, as you said, stress produces insulin.
Not just the food. I have left ads of stress and worry everyday and I am still diabetic even though I followed all the advice . A bad souse is just as bad for insilin
@@alisonnorcross951 All the best !
💯💯💯💯💯💯💯
And cortisol ... it sends you haywire and noone knew it. Add babies (which apparently forces insulin resistance) then menopause and your doomed and left feeli g like its all normal and your own faulr. So why isnt all the true scuence available being imolemebted. Clearly doesnt suit someone.
A real doctor!! The old Fungster is killing it. The world is beginning to wake up to the deception. Thanks Doc!
I always liken it to the Coca plant... Where the Coca plant grows they drink it as tea and use it medicinally, but when refined becomes a highly addictive drug!! Same concept for Carbohydrates!!
Very true! A friend of my parents went to Bolivia many years ago to teach people how to build houses out of concrete. He spent a long time there and used coca leaves every day. He said that it was like coffee, you felt a little less tired and a little less affected by the high altitude from it but there was no withdrawl like with coffee once he left the country and stopped.
this is a real doctor who can heal. Not just treat but heal..
Thank you for your videos. You inspire me so deeply. Your work should be mandatory learning for premed students. I'm learning how to be healthier every day and finding you has changed my life and the lives around me so much better. I find myself giving family and friends recaps of what you are teaching and it blows their minds. Thank you from the bottom of my heart and pancreas. Thanks to you I'm giving my pancreas a well deserved break from manning my fat reserves.
That was so eye-opening and seeing that it's dated back to 2013!! 8 years ago! I'm glad I found it ...better late than never. Thank you Dr. Fung
Same here. Super late smh.
Finally a doctor who know what he is talking about after following what he said my blood sugar drop to 3.8 daily well done Doc
This lecture changed my life.
I'm type 2 diabetic and was put on insulin last summer. Since then I've gained 40 pounds. A co-worker recommended Dr. Fung's book. I am anxious to read it and to see if I can control my diabetes with a change in diet and to get off this awful insulin.
pinesiskin59 How Are you doing now?
Not good. I'm off insulin and losing weight because of that. I still have not started a ketogenic diet. My blood sugar is stratopheric. I have no one but myself to blame. Just can't get in control of my eating. I'm hoping to complete a 36 hour fast to maybe kick things off.
*pinesiskin59* : Fasting can be tough when you're not used to it. Instead of doing a 36-hour fast, try cutting out one meal a day, so that you have at least 12 hours between two meals. Your body gets used to this new eating pattern without too much trouble after which you can reduce your eating window to 10, 8 or less hours. This measure alone is going to dramatically improve your metabolism. Nevertheless, you need to keep in mind that any kind of a fast remains very challenging as long as you don't cut down on the carbs in your food. If you combine fasting with LCHF, it becomes "a piece of cake": no cravings, no hunger ! 😉
Thanks so much for your supportive comment! I will definitely try this before attempting an extended fast.
Like the other commentator said, start slowly maybe just cut out breakfast, then after a week breakfast and lunch...
Also, I would not go past 24 hour fast, unless you plan to fast longer than 2 days. I only say that because Dr. Fung himself said there is no point of fasting for the 2nd day and stopping because the 2nd day is the hardest and than it gets easier.
Guys let's continue to learn from people like Dr Fung and let's do as they say, I bet you big pharma doesn't want all this
Hawaiians too, as soon as they stopped growing their own food and bought their spam, corned beef, crisco, bread, etc from the stores, they got very fat and unhealthy. Westernized food changed their lives forever. Many of us
are now diabetic.
Thanks Jason. It's great to hear this information from the scientific/medical standpoint. I had a bad case of insulin resistance. Now, I have lost over 100 lbs thanks to a low refined-carb diet with a lot of healthy live and whole foods, no flour or sugar, and intermittent fasting. I learned this healthy way of eating in a 12 step group for food addiction.
How are u now did u reverse your insulin resistance
Dr Jason Fung work Is seriously underrated. All you see are a bunch of RUclipsrs who plagiarized his work on fasting, without giving him a good referencing.
Exactly!
Thank you dr. Fung - my glucose numbers are down and I am off medication and lost 35 pounds as a result of your message and insights.
My bloods was very good my nurse said 8 .3 she said I see your staying below 10 I feel so happy dr flung been out walking all day my legs ache dr flung but am a lot happier not stressed out today thank you dr flung
EXCELLENT EXCELLENT breakdown of what, how, and why insulin works in our body. As a viewer, i was engaged and im walking away more informed and confident than i did 3 hrs ago when i left the American doctor office. I do 16:8 intermittent fasting for years now but i snack every 2 hrs for fitness goals as i thought. I just was told im knocking on pre diabetic doors today and i couldn’t understand HOW. Im slim and curvy. Your video Answered ALL my questions and i plan to overcome this within the next 90days. I even gave up meat 3mos and still insulin resistance issues. THANK YOU so much Doctor Fung.
great lectures, thank you. THOSE WHO HAVE EARS, LET THEM HEAR.
This man is a legend! His online advice (along with eric Berg) helped me lose 20kg in 4 months, no jokes.
I'm very very happy to hear the medical information relating to obesity, diabetes and insulin resistance. Really great medical knowledge for good health. It's really working.Thank you very much Dr. Jason Fung.
I used to just exercise my insulin resistance. Terrible way to go. Now I have pre-diabetic legs. I'm working on it now. Thank you Dr. It'll take a while I take it. one meal a day and high fat and protein low carb is definitely helping.
By far the most knowledgeable guy to listen too. Thank you Dr Yung.
MultiMotherbear it’s Dr Fung
My mother is prediabetic. Wish she could understand this. I've been doing IF 18:6 and at times 24hr fasting. I'm going on 8 weeks and feel great. I lost 10 lbs and hopefully counting. I cut back on processed foods and sugary drinks.
Also, consume seasonal food. There's a reason why sweet fruits aren't available naturally all year long and are mostly in summer, so we prepare for winter. With modernity we can get anything at any time.
Terrific series , thanks Jason, this is so much more than what a documentary provides. Interesting that in the U.S. the rise in obesity in pets , glad you took time to address the farm subsidies and that the food important for us is getting very little to no subsidies.
Insulin/insulin resistance leads to fat gain makes sense.
Superb presentation. Indeed it was a genuine pleasure to watch and learn. Thank you.
The Aetiology of Obesity Lecture Series are worth watching. It could be the most valuable 7 hours in my life. In your life too (if you struggle with diabetes)
Jason is on the topic! Very interesting! I have lost 20 kg in no-time!
These videos should be translated to every language possible and be pinned on you tube main page. EVERYONE should know about this, everyone.
In a less corrupt world, the government would do it.
Always follow money, we'll understand.
people don't care enough about knowledge luckily we do
we should feed each other grapes...markela
😂😂
Guy in the classroom at 12:23 was like "I'll have a sugary coke while you lecture me on insulin resistance"
😂😂😂
I was just about to write this too!! 😂 cracks open a can whilst listening to the effects of sugar and insulin 😂 😂😂😂
jason u r brilliant i watch everything u put out thanku!!
But I wonder... what about mineral content of the diet? We know that Potassium, Magnesium, Calcium, etc. are very important in liver function, and in many other processes. And we also know that modern farming practices lead to mineral-depleted soils. As the soils are depleted, the crops grown on those soils contain less nutrition.
Most Americans eat a diet far too low in minerals such as magnesium and potassium.
What effect does this have on metabolism?
Diet soft drinks are just as hard on mineral balance in the body as the regular soft drinks.
The chemicals in those drinks leech minerals from the bones.
Which could explain why non-caloric-sweetener sodas don't seem to help weight loss.
polly jetix the sweet taste still stimulates the brain and may promote an insulin response
You can't really get much minerals from plants anyway, they are bound up in oxylates. They also unbalance your minerals because they have too much copper and too little of other things like zinc. Supplementing also causes problems. If you have some eggs every day your mineral levels will be fine.
@@LTPottenger , Why would u need to eat animals, birds, bird eggs, fish, dairy & oil to do this? U make no sense except paving your way for heart disease & cancer. U get all the vitamins & minerals & protein from a Whole Fodd Plant based diet. Read Dr. T. Colin Campbell's book, "The China Study"
@@jgrysiak6566 What you promote are artificial frankenfoods that are little more than sugar
@@LTPottenger I'm late but I found out about what you said the hard way. Both veggies and supplements messed me up big time.
This Aetiology of Obesity/Diabetes video series is very educative and explains what other doctors never explained, they just prescribed high doses of Metformin and Januvia outright.
GREAT PPT, THANK YOU SIR. huge respect.
I've researched this stuff for years and this lecture is still valid.
Thank you, Dr.Fung! I have been losing and gaining weight since my teenage years. A year and a half ago, I lost the most amount of weight 45lb, but slowly gained it back. I would exercise more and more but made little difference. At the rate I was going, I would have to be at the gym all day to get the same weight loss results. I have been reading a lot about your Philosophy, and I'm going to start doing some intermediate fasting and document my journey.
Kind Regards.
truly respect if tomo I am slim its all because of you I had reduce twice but on weight again .... ..
Thanks Jason for sharing your wealth of experience information! Much appreciated!
Another great video
So we should shop like a doughnut? Circle around the perimeter but nothing in the middle?
Speedy Gonzales yes lol Dr. Fung talks about Intermittent fasting with Ketogenic diet as well, look into it!
XD
Spot on with insulin resistance.
However....its not simply tolerance to inflated levels of insulin. The introduction of trans fats in huge quantities to society, replaced healthy fats.
Trans fats, very elongated ....utilized in making up cell walls, instead of shorter chained fats...distort insulin receptors and glucose uptake.
Insulin..not able to lock into cells, to facilitate glucose transfer...glucose levels do not decrease and the body spikes more insulin.
Trans fats are a primary cause of type 2 Diabetes
Wonderful lesson . home take lesson was for me ;obesity and diabetes are end result due the pressure of food and drug companies to the policy makers!
Excellent 👌 Doctor Jason
Dear Dr Fung - I understand that obesity DOES drive insulin resistance , and with TOFI persons, a just little fat around the abdomen can do it, with fat in the liver and in the pancreas. This is the work of Prof Roy Taylor,Newcastle.2009 and now 2016 clinical trial DIRECT . HIs concept of the personal fat tolerance level. He has shown that reduction of fat can bring back good pancreatic function and lower insulin ' resistance' although there are still plenty of unanswered questions.
It's BS though. It's all based on diet. Eating refined carbs or too much carbs causes liver fat. Foods like eggs clear it out.
@@LTPottenger read /listen to Prof Taylor's lecture on the twin cycles hypothesis.
Get healthy to lose weight not lose weight to get healthy. Eating healthy causes weight loss as a side effect.
Thank you Mr, it's really helpful
Great stuff, doctor!
This bloke is really good
Excellent! Sorry it took me so long to find you.
Thank you, Dr. Fung you are the best❤
Great explanation of the real cause of obesity
Fantastic! Whole foods and zero fats.
Yesterday morning before having any breakfast my blood glucose was 5.0 mmol. Without having a bite to eat I cycled 40km over strenuous hills and I checked my blood glucose level and it was 5.9 mmol. Goes to show that the body regulates itself to release glycogen when required. I did have something light after that but I had another 20km's to reach my car. The ride back was a bit tiring but manageable as I used a he as heart monitor to cycle within the green zone.
Very Good explanation
It seems to me that Type One Diabetes and Type Two Diabetes shouldn’t even have the same name. Please give us some advice on how a Type One Diabetic wearing an Insulin Pump can use Intermittent Fasting to lose weight.
Thank you Dr. Fung.
We are a little confused as to the meaning of insulin sensitivity. At 33:40-33:54 Dr. Fung begins to say when you are sensitive to insulin you tend to gain more ...; then he quickly changes that to the insulin sensitive ones will gain less weight, but the insulin resistant ones will gain more weight. Shortly after that at 34:09-34:44 he says when you are insulin sensitive you gain more weight. Please clarify.
Steve Rush So let’s say two people produce the same high amount of insulin and eat the same amount of sugary food. The resistant one will spike their blood sugar, but the sensitive one will gain weight. The resistant one will not be able to store as much so they won’t necessary gain more - although they may already be obese.
Our goal has to be insulin sensitive because that way we gain less weight, our páncreas produces less insulin because we are very sensitive to the few insulin is up there. if you start to eat refines your body will start to produce more insulin and you become insulin resistant and fat
Lol @ like we're some cow 😂 love him and Dr berg
Good rule of thumb - it's okay to eat carbohydrates but along with their natural fiber. I like that.
Hi Jason - I eat LCHF and have plateaued on weight loss. I eat once daily, at 6:30 pm, and fast the entire time in between 5 days out of the week. When I keep my sugar low by eating healthy vegetables (cauliflower, broccoli, green beans) I have a hard time keeping the number of calories up!! I add butter or coconut oil, but if I add too much I just can't eat it all (which is a very new problem for me, lol). I think my difficulty is that if I can't eat enough calories, I'm getting into calorie deficit because I'm getting full before I hit my resting metabolic base rate of 1,500 calories a day. Should I increase my sugar those days so I can meet the calorie minimum and just have more 36 hour fasts?
maybe look up the website "mark's daily apple" for answers there
Dr. Fung's recommendation in this video is to eat within an eight to ten hour "eating window" so, perhaps, you should try eating two or three meals - the first at the beginning of the window and the last by the end. For instance, have the first meal at 10:00AM or 12:00PM and finish the last meal by 8:00PM. Personally, the last thing in the world I would do would be to eat a bunch of sugar just to get my calorie count up. Just adding 200 calories to your daily intake using sugar alone will require you to eat slightly more than four tablespoons of sugar. Yuck!
I personally find 30-36hr fasts more effective on ADF or 3 days/week than the shorter-term
I agree-36 hour fasts are optimal. Sleeping on an empty stomach that second night leaves my skin glowing and my appetite under much better control-in fact I usually have to make myself eat when I wake up.
Try fasting 2-3 days in a row, then eating well the other days.
Great lecture
One more thing to Dr. Fung...Your content ends a bit before the video ends, so I had to manually skip to the end to view the ad and activate the ad revenue. Maybe you can add an ad right where the content ends so we can actually pay you back for all the wonderful, free advice!
Would love to see a debate between Fung and McDougal/Gregger/Esselstyn. Also, Dr. Walter Kempner was reversing diabetes and Kidney disease in the 1940s with white rice and table sugar. Would love to hear Dr Fungs opinion on that too.
Kempet diet was a starvation diet with around 1400 kcal, so yes you loose bodyfat and your insulin sensitivity increase, but is is not a long term solution :/
It musst be a lifestyle, OMAD works perfect for me
What's the point? They don't use science only weak statistics which they pretend is science. Same with drug companies. Real science is based on experiments and is essentially just fact. Your body works on chemistry not made up hippy garbage nonsense.
Dr. Jason, i don't drink coke or any sugary drinks. I dont eat chocolates, ice cream, cookies or cakes. The one thing sweet i take everyday is lil critters omega 3 which is a sweet gummy bear that is coated with sugar. Do you think this is the one that causing my paresthesia or peripheral neuropathy?
riccia888: I'm assuming your paresthesia or peripheral neuropathy is a continuing disorder and not something that comes and goes as you eat particular foods. I'm also assuming that it's probably associated with diabetes or prediabetes. Google Blood Sugar 101 and click on the top result to enter the website. Scroll way down near the bottom to the link, "Download The Lower Your Blood Sugar Flyer". The flyer is a one-page instruction on how to determine which foods cause you to have elevated blood sugar. The flyer will teach you how to know how to know so you don't have to guess any longer. Why don't you throw away the gummy bears and use an oil capsule for your omega 3?
bread and pasta and plant oils are just as bad or even worse. And if you are prediabetic then even vegetables may have to go.
Here is a question that I cannot figure out the answer to. If I fast and my Blood sugar goes up to 280 do I take insulin or not. I am confused between what do I do if my blood sugar will not stay down. I have lost 40 lbs but I worry when the blood sugar goes over 140. I have had diabetes for 40 years and I think the desire to stay between 90 and 140 is foremost in my mind. When I am unable to take insulin my blood sugar goes up. I eat twice a day and not much food, meat and no carbs.
Would have been great to hear the questions...
funny how you hear people popping the tops of soda cans during the lecture.
MothraVsTheWorld lol i thought i was hearing things
Lol
Wow your explanation is awesome here. Thank you so much. I've followed you on DietDoctor.com for years, but never heard about how Insuline Resistance sneaks up on you over the years. Now I understand!! I was a thin child! But as the years passed, when we started eating our not Mother Approved food out away from home, I started to Plump up. Now I see. Wow. But your advice these days, now in 2019 has certainly changed, now you recommend a lot of FASTING and NO CARBS. That's a big change!
I eat breakfast at 11am, and dinner 530-6......then fast until 11 again.
What do you eat though? Intermittent fasting is important but what you eat is also very important.
Meat, eggs, butter, enough healthy fats, that means nothing out of a bottle, animal fats from sustainably raised animals, grass-fed grass-finished ideally.
But what do you eat for breakfast, lunch, and dinner to keep from being very hungry in between? I'm 59 and always had something to eat in between because I was always hungry. Note that I was always skinny. Even today if I have 2 eggs in butter with some veg for breakfast, i am really really hungry a couple of hours later. I wake up hungry. I don't eat much processed carbs. Blood sugar always seems to drop. I have no sugar cravings at all.
Add more healthy fats to your meals. I'm 57, and ditching the processed carbs are so hard for me, but if I add more fat, it controls the hunger.
I eat 4 eggs with 2TBS ghee and that keeps me full until dinner
I’ve been trying a 20/4 intermittent fast the past week but did not lose weight. I’m not diabetic but I am pre-diabetic. How long does it take for the insulin resistance to correct so I can start losing?
Try skipping some days
Great stuff 👍👍
Dr. Fung....do you have a special video or direction on childhood obesity and what you recommend? A book perhaps??
He recommends changing what the child eats, no fasting for a growing child
Just don't eat. Fast! No snacks, 2 or 3 meals a day. Dr. Fung has repeated this over & over!
Globally the poverty correlation falls apart since $30,000 a year is not poverty when compared to poorer nations, but is very true in the US since like you said corn and wheat is subsidized.
This thermostat effect is also happening in fasting. While you fast, you start not to lose weight but you must go on fasting not to gain again. It never helps to lose weight after a point especially for fertile women.
Around 30-35 minutes, I am a bit lost. Am I sensitive or resistant? Or I have insulin effect? It’s a lot of info... 3 hours of Dr Fung. I’ll take a break and come back to it later!
Did you figure it out?
Ok, so I still need to know....are my Metformin and my Jardiance helping me reduce insulin resistance or not? They definitely help with glucose meter numbers, but I now see that glucose levels themselves are not the main issue.
They don't, check out dapagliflozin
This video needs to be updated with the new "overflow" paradigm instead of the "internal starvation" paradigm to more reflect what you are currently publishing.
love this video 🥰
Does it mean that carb cycling days is also beneficial?
"If I look at a donut I gain 2 pounds" 😎
Cecelia pham lol
you should come over and let me take your mind off food...lol
Just dance can’t hold us back
@@kennsmith2424 🤮
Just don't eat oil or anything cooked in oil. Oil is 4000 calories a pound, the most calorie dense food on the planet!
eating during soccer practice makes sense from a performance perspective... but that's not snacking, it's replenishing energy stores. Kids who are just sitting around should not be grazing.
