Dr Fung was my first contact with the concepts of fasting, today I run a small consult where I address obesity and insulin resistance, I've had very good results using fasting with improvements in insulin sensitivity. Then I found you, and you've guided me to a lot of interesting studies. I find your channel much more informative. Thank you Nic.
I’ve always had the stance that modern health focuses too much on symptom control and curative medicine instead of preventative measures and screening. Here in the U.K. where we have the NHS, this approach is very expensive and doesn’t support a healthier society, rather encourages the reactive approach to healthcare.
Agreed. Its the same here in the USA. I think people's habits also force the hand of the doctors to treat symptoms, because what else will they do? Tell their patients to exercise and eat less? Sure, but how many will do it? Doctors' hands are tied by the public.
I disagree. This is not different from saying people's health issues are their own fault, while nobody should be blamed for their own suffering. We are far more fitness-aware than previous generations, to the extent that the ideal body type is no longer realistic to most of the population, putting people at risk of eating disorders. Some parts of the fitness industry, such as the weight loss industry, worth billions of dollars like their pharmaceutical counterparts. The factors that influence lifestyles that individuals cannot change, such as food justice are almost never discussed.
@@cfromnowhere you know exactly what you're trying to communicate, but you failed to effectively communicate it. I wish you would redo your comment to remedy its communication flaws.
I feel like I get a relatively well-rounded layman's understanding of these sorts of things when I listen to a combination of your channel along with Dr. Fung and Dr. Benjamin Bikman. The explanations of your agreements and your disagreements are helpful and enlightening.
My direct experience. While very low carb and fasting gave me fast results in weightloss and kept my metabolism "clear" of insuline's spike, which is good , my energy levels were clearly regulated by stress hormones instead of glucose metabolism and the presence of glucose did not change them. I started to consider energy that complex of alertness, mild anxiety, reactiveness. Ended with overtraining, real overtraining (like hours of rock climbing every day, at 45y). My body had totally shifted and probably was insuline resistant in the muscles to preserve the glucose for the brain, cells, etc. So in the long, I llprobably caused myself to become insuline resistant, after I had also regained my weight back, so the belly that also interfers with glucose metabolism. Losing weight now is terribly difficult, stress hormones kick in immediatly and I can't skip a meal, which was so easy in the past. So people, be careful with prolonged glucose restrictions
But I do not understand. My understanding is that the healthy human body is always able to maintain the proper blood glucose level by converting its stored fat into glucose. Sorry, I'm trying to understand. So, I need to ask you the following questions: Were you doing the low carbohydrate, high fat, at least 1g protein for each kilogram of learn mass body weight, form of either the vegan, vegetarian, or carnivore diets? Which diet were you doing and for how long? What tests did you have done to unequivocally confirm that you had increased insulin resistance? What symptoms do you experience if you skip a meal? So, in your case, you think your low carb diet combined with continuous high intensity physical activity, actually increased your insulin resistance to preserve glucose for your brain, cells, etc. Would you say then, that individuals consuming your same low carbohydrate diet, without continuous high intensity physical activity would be unlikely to experience the harmful symptoms you report?
Very nice video, and I really like the way you give Dr Fung the respect he deserves while still being a perfectionist about the finer points. I have added this video to my personal list of favorites and will watch this video again, in future.
I guess what Dr Fung was implying is that good glycemic control with diabetics will prevent issues associated with hyperglycemia but not necessarily the whole spectrum associated with Hyperinsulinemia. In one of his videos he was asked why doctors don't usually order a fasting insulin test and his answer was because there is no item to prescribe as a response to test result. Thanks for your video, it was clear, respectful and well intended.
I have to disagree, I've been an RN since 1978 and even back when I was in college it was known that tight control of blood glucose levels did not correlate with better health outcomes..I've also seen it many, many times first hand. Patient's whom we controlled with many tests per day still advanced to poor outcomes. Perhaps these glycated molecules should cause more problems, but if you are going to say something like that, you need to show the research that supports your fact. Dr. Fung mentioned 3 studies that showed no statistical difference. You state biology, which if correct, should be supported by some research study.
I've been taking metformin for months and one day I woke up not wanting to take it anymore. But want is different from need. I may not want to take it but my body might need it. So I decided to do OMAD and keto. Cut out all the sugar especially sugary drinks and most carbs especially rice and pasta. Type 2 Diabetes is a metabolic, lifestyle disease. I just opt to manage it by changing my eating habits instead of taking metformin. So far so good.
But metformin indeed decreases insulin resistance, unlike other drugs like sulfyonlyureas . Weight reduction also , people undergoing bariatric surgery hav reversed their diabetes .
Dr.Fung never said not to control your Sugars in the entire video ever (even if you watch the longer version of it). He said 'in the context of treating diabetes and the complications that follows after like kidney damage, heart strokes etc., merely controlling blood sugars have no impact at all and it doesnt make a difference unless you treat insulin problem'. Viewers should be careful about what they are deriving from his speeches. There is no point of his' that needs to be disputed atleast in this scenario. Many times, Dr.Fungs statements are twisted or understood out of context. For example whenever he says mere calorie restriction doesnt work without addressing harmonal problem, some automatically thinks he is against Calories in Calories out theory. Whereas his point is basing our approach merely on calorific restriction for fat loss would not work and we need to apply a approach in conjunction with regulating harmones (proven studies he presented in his lectures and books).It is not only important to lose weight but also to not become insulin resistant in future while doing so.
I thought the major part of increased insulin was to remove damaging sugar from the bloodstream. To protect from its damaging nature when left in the bloodstream. Obviously, in addition to getting nutritive glucose where the body utilizes it.
High blood sugar (A1C at 6.4 - 6.8 for a prolonged amount of time) damaged the nerves in both my feet. I can walk on snow in the winter time and not feel cold at all. I've fixed this with diet and exercise. My A1C is now a "normal" 5.4 but the nerve damage is irreversible. It is important to "control" your blood sugars while you're fixing insulin resistance which I believe is caused by fat gumming up your cells and making insulin less effective (assuming your pancreas is ok).
@@LTPottenger I don’t know about that. I think the best I can do is stop it from getting worse. Maybe you just had bad circulation and not nerve damage. Nerves don’t grow back.
@@donwinston This is what I found... "In all seriousness, though, recent studies have actually been showing that red light therapy, also called low-level laser therapy, is a really effective way to regenerate those frayed nerves that have fallen victim to peripheral neuropathy. On a cellular level, red light wavelengths are proving to have a beneficial effect when absorbed by releasing nitric oxide, boosting cellular growth, and directly encouraging the regeneration of peripheral nerves."

There is also the widely held belief that excessive blood sugar is also the cause of insulin insensitivity/resistance, not merely a symptom. This begs the question of what research science has to say about what causes cells to become less sensitive to insulin? As a type2 diabetic myself, I am very interested in learning more about both the cause(s) of insulin resistance as well as whether there is any actual scientific evidence that it can be reversed.
So what to do about the elevated levels of glucose in the blood? Force it into the cell- or burn it and reduce intake. Or take sglt2 inhibitors to pee it out? For the layman, burning it is fasting and a low carb diet is reducing intake.
So isn't low carb, carnivorous keto diet also managing the Symptoms by not letting blood sugar rise? Does high fat really promote insulin sensitivity, which is defined as ability of insulin to efficiently transport glucose into cells??
Glycation I'm aware of but I'm not sure what is the mechanism by which hyperinsulinemia leads to disease. It is central to many disease states as Ben Bikman talks about in his book "Why We Get Sick" but specifically HOW does it cause the disease state? Or any of these disease states?
@@Physionic no, hyperinsulinemia. Insulin resistance is at the heart of it but I was wondering if insulin itself can be directly involved. I know in PCOS the hyperinsulinemia has a direct effect but uncertain of other disease states.
Very Interesting, I Recently Heard Interval Training, As Professional Bikers Use, Could Help Mitichondria Production As Well As Help Control Insulin Resistance, 45 Seconds Hard Intensity, 30 Seconds Low Intensity For About 20 Minutes Daily, Your Thoughts? :)
Weirdly I agree with both of you. Yet i expected to disagree slightly with both lol. The problem is not sugar per se but insulin resistance and even more it is actually the increase risk of mortality (cardiovascular, kidney etc). Now the conclusion that follow: Hence the problem is fat(increase insulin resistance and mortality for saturated one at least) and animal products(that increase mortality and contain dirty fats/protein, no fiber etc)....
@@Physionic not a first lol. I do not know well enough dr fung. You i agree most of the time i just do not say it everytime otherwise i feel its weird lol some stakeful disagreement also as you know and some nitpicking sometimes maybe 😉
