    - VIDEO DESCRIPTION -
    Insulin resistance is a key factor underlying the development of type 2 diabetes, and also a risk factor for several other chronic conditions, including heart disease, stroke, and several types of cancer. Insulin resistance does not have a single cause, but can be triggered by numerous factors. And understanding why someone is insulin resistant is the first step to reversing insulin resistance. In this video, we are discussing the sixteen top causes of insulin resistance.

      My glucose always starts to rise starting 10:30pm and throughout the whole night til next morning until I eat (100-120). I know that morning spike is due to dawn phenomenon, but I don’t understand why it starts rise before midnight and throughout the whole night (the highest number). I eat low carb diet. During the day, my blood sugar is in the 90’s. What other factors could it be? Hormone?

      @@mybabygirl666 So your blood glucose starts to rise about 3 hours after dinner. Carb digestion starts in the mouth as the saliva contains amylase which releases glucose (not absorbed in the mouth but you can taste the sweetness) whereas protein digestion starts in the stomach into peptides and continues in the duodenum (first section of small intestine 12 fingers long, your own) by pancreatic proteases. Peptides are not absorbable and can cause passing of rotten egg gases (hydrogen sulphide). Incomplete digestion of carbs feeds your gut bacteria so they don't have to feed on your mucin layer causing leaky gut syndrome. Fats don't get processed until they reach the duodenum where they can be emulsified or digested into free fatty acids and glycerin (aka glycerol, a carb). Emulsification depends on bile salts and cholesterol all secreted by the liver and stored in the gallbladder. Fats in the stomach coats other food fragments interfering with their digestion and formation of chyme, thus causing satiety and delayed gastric emptying. If you have a large fat intake and/or low bile output, you can end up with steatorrhea (fatty diarrhea).
      May be try a more balanced dinner with a smaller portion size.

      Insulin has numerous anabolic actions, including increasing protein synthesis in muscle and decreasing the breakdown of muscle protein. If we are insulin resistant, the cell may not receive the full insulin signal, and therefore the muscle-building process can be impaired.
      Follow along on the channel over the next few weeks and months to learn how to improve your insulin sensitivity. Sorry for always referring to future videos, but there is so much to say about that, it wouldn't make sense to type it up here (it would be a book!).

A protruding belly is an indication that the individual has fatty liver and ran out of storage in the liver and so the next option is around the midsection. Kinda like a beer belly.

    Mario’s presentations are one of the best I have seen so far on the internet concerning insulin resistance and diabetes. What I find very disturbing, with all the new science available, how much or better, how little the medical world is applying the new information.
    As long as the financial interest of the medical world and the influence of the big pharmaceutical companies prevail, backed also by some questionable politicians, a lot of people still will be maltreated for years to come. Pushing the pill by treating the symptoms and not the root cause! This will break our health system in not too further distance throughout the world.

      The current medical system is truly broken in most countries. It's such a shame that we have armies of passionate, smart, and dedicated professionals such as physician and nutritionists, and we are not using them to their fullest capacity to help people prevent chronic diseases. I actually think these professionals are suffering as much from this medical system as the patients. Change is long overdue, but until that happens, I do think arming people with the knowledge to help themselves is the best we can do. I honestly think that prevention is where it's at.

    Hi Mario, I wish I had know about all of this before my problems hit. You are so right about the hidden chronic diseases that are caused by insulin resistance. After finding out about my NAFLD I started reading and found out that over 30% of the world’s population are probably walking around with fatty liver. Studies show it to be epidemic. It is one of those things that pops up accidentally when having a test done for something else. People often ask me well how come you didn’t know. Didn’t it show up in your labs. I had normal liver enzymes and lab work. It was found when I had a bladder scan for another reason. Then sent to hepatology Dr. He did a fibroscan and there it was. I was very lucky because now I am working to reverse it because it had not reached the fibrosis stage. It would not have been long because everything was going up. B/P up, cholesterol up, weight up and I had a border hgb A1c which never was high. I now watch all your videos and will continue to watch them all. I struggle but at least headed in the right direction. Thank you

    • @nourishedbyscience
      @nourishedbyscience  Před 7 měsíci +7

      Thank you, Cathy, for sharing. I am glad to hear you found your NAFLD early. Dietary and lifestyle change are quite powerful in reversing the condition at this stage.
      Your story is not the first one of this kind that I have heard. So often in the clinical trials I have led have participants shared that once they hit a certain age, they felt like their health was slipping away from them, and every 2-3 years they needed a new drug for elevated blood lipids, high blood pressure, diabetes, painful joints etc etc. I have absolutely come to believe that we ourselves need to take matters into our own hands by educating ourselves, asking for lab tests, and changing our diet and lifestyle preventatively. The slow accumulation of visceral and ectopic fat as well as insulin resistance in particular are linked to so many other risk factors such as blood pressure, high blood sugar, high blood apo B/LDL-cholesterol, high triglycerides, high inflammation markers etc., it doesn't make much sense to me that we don't pay more attention to these markers in primary clinical care so that we can fight the causal factors early.

    Due to advancing age and some minor health scares, I'm new to the self-health interest crowd. Of the myriad of health related CZcams influencers that exist, this channel has become one of only two that I have come to trust. I haven't seen a lot evidence produced here (in the form of reference to specific studies, particularly meta-studies). However, Mario's discussions seem to me to be very high level and consistently reliable when I research his ideas elsewhere, and with every Nourished by Science video I watch, I become more trusting that this dude knows what he's talking about.

In clinical medicine, all we consider is diabetes (yes/no), where in reality there is not just black and white, but many shades of grey in between. That said, it's a great opportunity for you to find some shifts in your diet and lifestyle that you can happily live with in the long run and that can help you normalize that glucose tolerance.

    Thank you again Mario. It's been very clear to me that insulin resistance is simply **not** taken seriously enough as an urgent problem to address, at least here in Australia. Only once people fall off the insulin resistance cliff into full type 2 diabetes does anyone do anything, and that usually consists of "oh here's some Metformin, and try to eat healthier/exercise". This level of public health intervention is far too weak to have anything like enough impact.

      @nourishedbyscience, I cannot wait to see this next video. I’m often shocked at the intelligent, educated people I know who believe their Type II Diabetes is “hereditary.” As the oldest of 5 kids, I grew up in a household where there was no money for junk food and soda. For sure, we had some things like hydrogenated peanut butter and store bought mayonnaise, but our big treat was popcorn. Fast forward into adulthood and all five of us are over 65 now. One sister has scleroderma, another has really bad arthritis. One brother has numerous joint, BP, and lipid problems. Another brother is OK for now. Three of my siblings have had cataract surgery in their 60’s! It’s just heartbreaking to me.

      Insulin resistance is the result of over consumption of carbohydrates. Our bodies are not designed to eat as much carbohydrates that we do in maternity. Unless you’re extremely active and Carbo load for a marathon we don’t need to eat as much carbohydrates as we currently do. Overconsumption of carbohydrates creates a fatty liver think forced delicacy it’s now band nearly everywhere because it’s an abusive practice but in humans and by choice because addiction to carbs being always hungry and can’t stop eating or drinking is beer good equals fatty liver disease fire alcohol and fatty liver and fat people is known as non-alcoholic fatty liver it’s caused by insulin resistance Andover consumption of foods that raise blood sugar. Other than fruits plants don’t want us to eat them and fruits are there to get animals to spread the seed for them by enticing them to eat something sweet and delicious and originally not available in the quantities that we have available to us today and anytime of year all the time.

    • @nourishedbyscience
      @nourishedbyscience  Před 7 měsíci +13

      @@Sarah-with-an-H Sorry, Sarah, but I'll have to disagree here. I realize that what you are sharing is a wide-spread belief in the low-carb community, but I don't think the cumulative data support it at all.
      If you are open to considering the data, I invite you to review the data from 21 randomized controlled trials with me in this video:
      czcams.com/video/ZcVenUbqsYY/video.htmlsi=i-zjpkEJ_EbaEYAA
      Many of these are well-controlled feeding trials where all of the food was provided to participants (i.e., we know excatly whay they ate) and in which insulin sensitivity was assessed by the gold-standard method, the hyperinsulinemic-euglycemic clamp!
      There is very clearly no consistent evidence that high-carb diets per se, i.e. when controlling for changes in body weight, trigger insulin resistance. Just like there is no consistent evidence that high-fat diets trigger insulin resistance, as is often claimed by low-fat vegans.
      You mention addiction to carbs. I understand what you mean here, but is anyone really addicted to legumes, whole grains, and starchy vegetables? Is it really the carbs themselves? Or are people addicted to carbs in the form of ultra-processed foods, refined grains, and added sugars? If the later, is it not a bit superficial to claim that all carbs are similarly bad?
      Also your argument that plants don't want us to eat them is not all that convincing. Do animals want us to eat them? Of course not. And if what you mean are antinutrients, yes, I am also very interested in that topic and will cover it in time, but do we really have data that suggest that eating plants leads to poor health? Come on!
      Lastly, carbs cause fatty liver is as much incorrect as saturated fats cause fatty liver. And the latter point I could even support with a well-controlled dietary intervention trial. The biggest point here is that both carbs and fats can promote a fatty liver if we overeat calories chronically. And maybe if we consume a lot of fructose in liquid form (even though that almost always leads to caloric excess as well).
      I don't take sides here in the tribal diet wars. My side is that of evidence. I am willing to consider the very interesting anecdotal evidence of health sucess stories people in the lwo-carb, keto- and carnivore communities are having. Really interesting stuff. But I am also interested in the very good long-term health in people who eat whole-foods plant-based diets, and the excellent health of many populations such as Italians or Japanese who to this day eat diets rich in carbs but low in ultra-processed foods and who have much, much fewer problems with obesity and diabetes than the US or much of Western/Northern Europe. We should try to reconcile these data, and not pour the baby out with the bathwater.
      Looking forward to your response. I get a lot of comments from both the low-carb and low-fat crowd, but no one ever seems seriously interested in learning something or being open to an argument and engaging with it.
      Best wishes,
      Mario

    Thank you so much for making this video. The amount I have just learned will help me tremendously! I am borderline diabetic type 2, but not particularly heavy. However I have had problems with my circadian rythme for a few years and I have almost never been athletically inclined. Now I understand better what I have to do to avoid ending up on drugs. My sincere appreciation for what you do❣️

    I would encourage you to learn from Jason Fung, carbs cause insulin resistance. The science is settled.

    • @nourishedbyscience
      @nourishedbyscience  Před 7 měsíci +4

      I'm sorry, that is not how science works.
      First, there is very little in science that is 'settled'. We should always be open to new data coming in to continually test our hypotheses.
      Second, I do my own research, rather than copying what other experts say. And the data in this particular case do not at all suggest that high-carb and low-carb diets differ in their impact on insulin sensitivity (once we take body weight out of the equation, as we should):
      czcams.com/video/ZcVenUbqsYY/video.htmlsi=gQK71JLy-U2o9-HX
      Aside from these randomized controlled trials, the assertion that carbs are the cause of insulin resistance and obesity cannot be reconciled with evidence that many people, in fact, entire populations, consume high-carb diets consisting of whole foods have very few problems with diabetes and obesity to this day (Italy and Japan, for example). To me, speaking of carbs if what we really mean are refined grains, added sugars, and carbs in ultra-processed junk foods is an unfortunate superficiality.
      So if you had said that "overeating refined carbs and carbs in ultra-processed foods, and constantly snacking on them, may contribute to insulin resistance", then I would have agreed with that statement.
      Best,
      Mario

    • @nourishedbyscience
      @nourishedbyscience  Před 7 měsíci +5

      And, to add, I also would not encourage anyone to simply believe that what I am saying is correct. Science is not a game of he-says-she-says. We need to look at the data. That is why for every single video, you can find a blog post (linked in the description box below each video) that lists all of the references relevant for the topic.
      Also, and importantly, for each question I consider, I look at the cumulative evidence, rather than trying to find one paper that supports my position, as so many people online do. For example, for the question of whether low-carb or high-carb diets are better for insulin sensitivity, I considered 21 randomized controlled trials. You are more than welcome to read all of them yourself; they are all linked in the blog post. You will see that in most of these, insulin sensitivity is not lower on diets rich in carbs, and most of the studies used the gold-standard measure of insulin sensitivity, the hyperinsulinemic-euglycemic clamp.
      I am so passionate about this issue because I see so much poor science online (that's exactly why I started this channel). Most 'experts' do seem to think that you can say whatever you want, as long as you can find one paper to support that statement. That's absolutely incorrect. The scientific method means that we constantly have to WANT to disprove our own hypotheses, and consider all of the evidence. Because in the 21 papers I considered, there were 2-3 that could support the statement that "carbs cause insulin resistance", but also 2-3 that could support the statement that "carbs improve insulin sensitivity and fat causes insulin resistance". See what's wrong here?

    Thank you so much. I thought I knew about insulin resistance and have followed a ketogenic diet for 5 years. I had an initial weight loss but have stalled dreadfully.
    I worked much of my nursing career as a night sister, but for the past few years have worked reduced hours on day shifts, I am 65, so it's a semi retirement post.
    I have felt very stressed lately, both with life problems and too much "news"!
    I have recently given up coffee (6 weeks) and the difference is incredible. My stress levels have dropped and my sleep very much improved. My weight is starting to drop again.
    Thank you for helping me to understand the missing links.
    I walk plenty, but I think it's time to dig out my old weights!

    SunnyV, in regards to your comment, yes my siblings and I all grew up eating the same diet of no processed foods. But, and this is a big one, once we became adults, our eating habits changed radically. I shudder when I see the foods they and their families eat. I do believe their serious health issues are attributable to their diets. There for the grace of God go I though. I became seriously interested in nutrition when I married at age 23. I was determined that my family would eat the healthiest food I could make. I became even more fervent when our first baby arrived. I guess what I’m saying is that this healthy way of eating is for the long haul and will help you regardless of your genetic makeup.
