Ep:276 THE RANDLE CYCLE - EXPLAINED AND DEMYSTIFIED by Robert Cywes

[@biancagadi786]

Dr. Cywes, your way of explaining complicated biological/medical/scientific terms and processes is so clear and to the point without fluff. I always wanted to study medicine witht the goal to become a brain surgeon. However I was not smart enough to enter medical school. Life has its way. Nevertheless, my interest in medical subjects has never waned. You, as an accomplished medical professional offering these free lectures, provides us lay people with invaluable access to knowledge. You spent years to acquire this knowledge, and all we have to do is listening for a short time to start grasping complicated concepts. I consider you a master teacher. thank you for your effort.

[@xmenotux]

I see a lot of people suggesting this video discredits Bart Kay's understanding of the Randle Cycle, but it doesn't seem to do that at all. Both Dr. Cywes and Bart Kay seem to be saying that cells prefer fat, and in the presence of fat it doesn't utilize glucose. The mitochondria, once satisfied, will block further energy absorption. As I understand it Dr. Cywes is merely pointing out some nuance about how Randle incorrectly assigned causality to the presence of fat blocking glucose pointing out that Glut4 would facilitate the transport of glucose into the cell. However ultimately the effect is still the same, that the cell prefers fat and once energy requirements are satisfied it will block the glucose even with the facilitation of GLUT4 which would then cause the glucose to enter adipose cells. They are both saying the same thing about the effect of the Randle Cycle, Dr. Cywes is just providing more scientific clarification that Randle's assumptions weren't entirely correct because he assigned causality to the presence of fat instead of to the satisfying of energy requirements.

[@adriansrfr]

Beautifully stated

[@aspiresk8boarding]

Cell arguably prefer burning glucose as they increase the nad to nadh ratio which speed metabolism of the cell, creating more atp and co2 production with less reductive stress and ROS. With a high metabolism from glucose burning that energy systems won’t be “satisfied” for long compared to fats. The brain, red blood cells, CNS, and kidneys for example need a constant supply of glucose

Great video! You are the first have seen that brings up the role of glucagon with relation to the Randle cycle! I have severe type 2 diabetes. Even after a full year of strict carnivore diet and cutting out all meds, including insulin, my average blood sugar was in the 270 range. I finally twisted my docs arm and got both a fasting insulin and fasting glucagon test. My insulin was 12, so high, as expected. But my gucagon was only at 18, so severely depressed. So then the depressed glucagon no longer restricts the insulin production, which again makes my liver produce as much glucose as possible, to get rid of the excess insulin. Then Ben Bikman explained the role of glucagon in detail and the fact that eating healthy saturated fat actually boosts glucagon production, thereby LOWERING the insulin production. So if you wanted to conspire to get as many people as possible to die from the effects of insulin resistance, the obvious first thing to do is to completely demonize or ban eating saturated fats... Something to think about... With all this information I have devised a strategy for curing my diabetes. I do periods of 9-10 days of waterfasting combined with daily exercise. This will after a few days completely normalize my blood sugar. Then when I start eating, I ONLY eat fat, as in lard, for the first few days. After completeing two such cycles, my avarage blood sugar is now reduced to around 130 when eating a normal carnivore diet. I believe that with a couple more of these cycles, my diabetes will be cured. So get tested for both blood glucose, A1C, fasting insulin and fasting glucagon. That gives you a complete picture of what is going on.

[@uberneanderthal]

i've fasted several times, even dry fasting, and I have to say the health benefits are exaggerated. there's less stressful methods for achieving equal or greater results. it may be necessary in your case, idk. but I would attempt less severe protocols first. the rule should always be: if you're hungry, eat. the only exception is carbs, since our instincts are evolved for an environment where carbs are rare and seasonal, nothing like our current environment.

I really recommend the lectures of Dr Richard Johnson on the metabolism of fructose to get the most recent discoveries from a biochemical and physiological perspective.

[@GoldenBlaisdale]

Hey Dr Cywes As this video is three months old, I don’t know if you’ll see this post . The issue with some very loud influences regarding the Randle cycle is that they use it to deny insulin resistance. I think they read Randle’s paper as showing that once the cell is full of energy, the cell itself down regulates the insulin receptors to block more energy coming into the cell, because that would be deleterious for it. They say because trying to put too much energy into a cell is toxic for it, the cells actively down regulate and force the excess fats and sugars to remain in the blood where they are also dangerous, but it’s the lesser of two evils. So insulin resistance is wrong as a concept. Thoughts?

[@xmenotux]

Most of what you said is true though, and Dr. Cywes's video does not debunk it. Also, who are these people saying insulin resistance is wrong? No one is disputing the existence of insulin resistance, but some are disputing it as a condition. And frankly from what I've seen of Dr. Cywes, he doesn't necessarily argue against that either. He himself is saying insulin resistance is a result of too much carbs and sugars. Even in this video he is suggesting too much glucose causes a disregulation of glucagon hormonal system. Why would you have too much sugar? Because your cells don't need energy either due to fat or having too much sugar to satisfy its needs.

[@GoldenBlaisdale]

@@yann664 nice explanation my understanding is like yours but a particular professor influencer who is dismissively dogmatic say's insulin resistance through hyperinsulinaemia is wrong

[@asherasator]

@@xmenotux Randle et al. for decades proved "Insulin Resistance" is directly caused from fatty acids released from cells. Glucose turns into alpha-ketones pyruvate that directly fuels B-cells to make insulin, IGF-1 growth hormone and glucagon. Too much fat in the diet or from cells stops it because the body must get rid of large fat amounts burning/oxidizing as too much fat and LDL turns into peroxide and is caustic, so glycolysis to ATP stops and lipolysis/beta-oxidation begins, and the glucose requirements for red blood cells, the liver and other parts of the body that must have it will trigger gluconeogenesis, then buffer higher glucose levels as reserves in the blood because it's a process to make, and the body will not and cannot make insulin for the glucose it just made. There is no such thing as "Insulin Resistance" only "Metabolic Inflexibility" coined by Randle for the body not being able to go back and forth properly from glycolysis to lipolysis as it does on a real "proper diet". Nobody told you before the body makes ketones 24/7 regardless of diet. Because of these empirical facts the food pyramid from decades ago was 100% metabolically and hormonally correct with carbs at 60-75% depending on BMI (body mass index) and BMR (body metabolic rate).

So, if following a carnivore diet, should i include a small amount of carbs with my fatty meat, or not? I'm so confused! Dr Bart Kay says to eat no carbs ever. But I've recently discovered that another role of insulin is to allow immune acids to ever a cell and stimulating protein synthesis. Which is good🎉, right! So that would suggest that *some* insulin production is a positive thing. Not excessive production, but some? I don't know what to do now. I'm so confused 😵‍💫😵‍💫😵‍💫😵‍💫😵‍💫

[@uberneanderthal]

protein stimulates insulin production, while avoiding the nasty spikes carbs create. this is why most keto diets are low-protein, because protein will 'kick you out of ketosis'. but the benefit of low-carb isn't ketosis, it's alleviating the Randle Cycle.

[@alphacause]

Dr. Cywes' explanation here, of a pretty complex topic - the Randal Cycle - is a great example of how to simplify something so as to make it comprehensible to a layperson. Dr. Cywes is not just teaching us about the Randal Cycle, but he is teaching a masterclass on how to distill the esoteric nuances of a scientific concept into something that is more accessible. Thank you Dr. Cywes! I am sure you are a busy man, but given how much attention the Randal Cycle has been getting, if time permits, maybe you can do a presentation on this with slides. Visual aids, especially when dealing with the such a intricate topic, helps describe things more clearly - especially for those who are more visual learners. Given how much the Randal Cycle is being used or misused to argue for a particular point, and just the sheer amount of misunderstanding there is around the concept, warrants taking the time and effort to do a deep dive into this topic.

So how do we increase insulin sensitivity vs insulin suppression? Great video btw.

[@arwenhardy1995]

I did it by lowering my carb intake to as close to zero as possible; eating two meals per day. Best regards.

[@lucia_cossu_voiceteacher]

For what I have understood it is a two phases process: by a ketogenic or fat adaptation process you get back to insulin sensitivity in most cases and when fat adapted you avoid the insulin suppression by reintroducing carbs one or two times a day (dairy for me is optimal and I do some days but have still cycles of pure ketogenic).

[@CarbageMan]

@@lucia_cossu_voiceteacher That's what I'm thinking. I've recently taken to having carbs after exercise, and I'm considering being more judicious about how much protein I eat in one meal, to limit gluconeogenesis.

[@erharddinges8855]

is this the key?

[@asherasator]

The only way to utilize the Randle Cycle facts is 60-75% carbs in the diet. Glucose/fructose becomes alpha-ketones pyruvate by glycolysis/fructolysis that directly fuels B-cells for insulin, IGF-1 growth hormone and glycogen. Keto diets slows or stops insulin production. Gluconeogenesis from fats/proteins stops insulin production. Cywes and those like him are 100% wrong in their premise and anti-science. All "ketone" and "ketosis" talk is gibberish, as the body makes ketones 24/7 from any diet. Lipolysis/beta-oxidation "keto" and gluconeogenesis for main ATP cellular energy source creates type-1 diabetes, and turns type-2 into type-1... regardless if glucose numbers are low, the pancreas, insulin, IGF-1, glucagon and many other hormonal mechanisms are disrupted, altered and damaged. That's why keto/carni ideas were short term treatments for obesity and epilepsy, and not meant to be long term as the well established empirical facts were understood. That's why the food pyramid from decades ago was 100% correct for metabolic integrity. The "Proper Human Diet" is plenty of grains, fruits and vegetables with lower amounts of proteins and fats. "MTHFR defect" is no mutation, but genetic proof most people's ancestors (~50% of the public) did not eat high methionine-homocysteine protein foods from animal sources. Methionine in high amounts is the most carcinogenic and toxic part of a diet. As it is angiogenic and can create blood vessels to infections creating cysts, nodules, fibroids, tumors and directly involved in many cancers. Amyloid proteins are also involved in many neuro pathologies. So protein intake at 30% and below is correct.

[@daleval2182]

Eat meat and fats ,which in return we become fat adapted , and our body will reduce fatty heart and liver, after we get the fats back to optimum, we begin to repair damaged insulin sensitivity

[@asherasator]

@@daleval2182 Your comment is wrong. Randle et al proved glucose made by gluconeogenesis does not trigger insulin and IGF-1 growth hormone production. In lipolysis/beta-oxidation mitochondria respire slower than by glycolysis/fructolysis and requires higher BMR (body metabolic rate) for fat/protein pathways to be main source for ATP so body surplus is used and weight comes off as glucose/pyruvate made is looping to maintain higher BMR, so the body just can't doing it all properly. That's why keto/carni low/no carb should be short term and that's how they were initially designed to treat obesity and epilepsy. Cywes is focusing on irrelevant details as glycolysis/fructolysis makes alpha-ketones pyruvate to ATP very easy. The alpha-ketone pyruvate is key in insulin, IGF-1 and hormone production including glucagon. These hormones have many more functions than just glucose. The whole point from Randle et al and many others decades later is that long term lipolysis/beta-oxidation [keto] and gluconeogenesis disrupts the entire metabolism and hormones and creates diabetes and "Metabolic Inflexibility" [not able to go back and forth from glycolysis/fructolysis to lipolysis]. Only in a balanced diet of 60-70% carbs and the rest proteins/fats in proper calorie intake can that be prevented and one considered metabolically healthy. Cywes is 100% wrong and trying to frame Randle into his subjective ideology of quackery and anti-science.

[@VanDamn911]

Ancestrally Appropriate Diet! (Short) Our evolved ancestrally appropriate diet consists primarily of Ruminant animals fed a clean diet of grass & weeds that reach deep into the soil & suck up nutrients unavailable near the surface, or from nutrient void GMO corn, wheat, & soy sprayed with carcinogenic glyphosate weed killer, & estrogenic pesticides. Some examples of ruminant animals are lamb, goat, deer, elk, bison, & cattle. Yeshua Hamashiach, (Jesus) said, "Eat split hooved animals that chew the cud." (Leviticus 11) These are ruminant animals with long four chambered stomachs biologically designed to be capable of breaking down plant matter, filtering out plant defense chemicals, plant toxins, anti-nutrients, & even many environmental pollutants, while also providing more essential nutrients than any other food, also making those nutrients more bioavailable or absorbable for us. The anti-nutrients & inflammation caused by plant defense chemicals puts us in a state of brain fog we can't tell we're in, until we find our way out. Benjamin Franklin said, “Life’s tragedy is that we get old too soon and wise too late.” We don't have long multi chambered digestive tracts like cattle & other ruminants, capable of breaking down plant matter, filtering out plant defense chemicals, & anti-nutrients. Botany teaches us that all plants, fruits, & vegetables have thousands of plant defense chemicals & anti-nutrients to protect themselves, because they are stationary. Anti-nutrients prevent us from breaking down, & absorbing our proteins, nutrients, & essential fatty acids. We've evolved to have varying degrees of tolerances determined by our ancestors' diets, & environmental factors such as weather, & religion, or dictatorships controlling diets for lengthy periods of time, which has altered our genetics at a molecular level, but that does not make them viable, or optimal nutritional sources. We're not biologically designed with long digestive tracts to break down plant matter or fiber, which are indigestible carbohydrates that feed bad bacteria! That's why we have to take pre/probiotics to break it down. This creates a science experiment, & balancing act in our stomach. Plant fermentation produces methane gas build up that expands our stomachs, stretching the walls of our gut lining, creating tears through which we lose Vitamin C, back into our blood, contributing to free radicals, & metabolic waste our bodies struggle to clean up, along with more nutrient loss, because we need Vitamin C to direct nutrients where to go. Inappropriate diets lead us to needing supplementation, but 90% of the supplements on the market are fake. Ascorbic acid is a molecularly incomplete synthetic form of Vitamin C that competes for the absorption of real Vitamin C. Cyanocobalamin is synthetic B12 that breaks down as cyanide in our blood. Cyanide was used by the Nazis to commit suicide when caught during espionage. Our bodies have not evolved to recognize these lab synthesized compounds made over the last hundred years, because it typically takes evolutionary adaptations hundreds of thousands of years or more to occur... Usually out of necessity for survival. They say small amounts won't hurt us, but I would argue that creating chronic inflammation that prevents us from being able to use mitosis, & autophagy to heal, definitely hurts us. These synthetic vitamins are added to many processed foods. Everything has a "root cause." Cause & effect are fundamental concepts in science that describe how "every action has an equal & opposite reaction." (Newton's third law) Mixing sugar & protein, like what's in a sandwich with bread & meat, creates sticky proteins or glycation, that sticks to the walls of our arteries, & solidifies or hardens, clogging them faster. Many vegetables have a glycemic index high enough to spike insulin levels, induce unhealthy glycogen fat storage, kick us out of ketosis, & out of fat burning, & into burning glucose. Glucose burns rapidly, & volatile, like rocket fuel, but fat burns slow, steady, & efficient. Evident by the deaths of many carb loading bodybuilders. We need to be burning fat in order to use our "fat soluble" vitamins. There's no such thing as an essential carbohydrate! Two fuel types trying to enter a cell at the same time, causes cell damage. Repeatedly damaging the cell eventually leads to cell dysfunction, overgrowth, & cancerous tumors. Glucose speeds up the growth of cancer cells. Sugar & high glycemic complex carbohydrates create the same damaging inflammatory response to our cells, & levels of dopamine response or addictive instant gratification signaling in our brain, as meth & cocaine! We burn glucose first as a defense mechanism to prevent it from causing problems. We can derive the 4 grams of glucose we need from fat, & that's all we can tolerate before being kicked out of fat burning & ketosis, & into unhealthy glucose burning, & glycogen storage. We are unable to properly regulate our blood sugar levels when we are creating insulin spikes with sugar & carbs, which signals our bodies to create more insulin signaling the storage of more glycogen fat. This glycogen storage is that which makes up the subcutaneous fat beneath our skin, visceral fat smothering our organs, & eventually clogging our arteries, causing heart attacks & strokes! Bad bacteria cannot survive on fat or ketones, but we thrive. We can starve out viruses like the Coronavirus, or bad bacteria such as Candida & yeast by avoiding sugar, fructose, & carbs our bodies turn into glucose, which feed bad bacteria. The dawn of agriculture brought with it mind fog, malnutrition, disease, pestilence, a reduction in overall health, lifespan, reduced size, reduced jawlines... evident by crooked teeth, & our wisdom teeth no longer fitting in our head, as well as reduced cranial cavity & brain size, & the optimal neurological function that running on ketones provides. Siddhartha Gautama (Buddha) said, "To keep the body in good health is a duty... otherwise we shall not be able to keep our mind strong and clear." Agriculture regressed our evolution, & made us smaller, weaker, dumber, docile, more manipulatable, & easier to control. George Orwell said, "The most effective way to destroy people, is to deny and obliterate their own understanding of their history." "Knowledge is power and it can command obedience."

@@xmenotux Wrong the cell and mitochondria prefer glucose as it creates more ATP per molecule. Randle and many others empirically 100% proved glucose/fructose [converted to alpha-ketones pyruvate by CoA (coenzyme A) then ATP] fuels B-cells to make insulin, IGF-1 growth hormone and glucagon. Only without insulin then the cell has to use fat and beta-ketones, the cell doesn't prefer fat that's a lie... because it's more work. Mitochondria respirate slower in lipolysis/beta-oxidation and make less ATP. The entire keto/carni premise is false and biologically and physiologically wrong. This is textbook facts.

[@pattib1731]

Dr. Cywes, I understand some of this, but too fast and detailed for me to synthesize and retain. Would like a simpler more concise explanation. Also would love a video with recommendations for labs to check for insulin resistance, glucagon excess, etc. I try to eat a lot of fat with meals and limit protein, but am not satisfied with less protein. This is on pure carnivore with nothing plant based or sweetness of any kind. Could glucose produced from higher protein be driving overconsumption? I think I'm a fatty with no shortage of insulin, not diabetic. Thanks for your great videos.

[@erharddinges8855]

At the end everyone needs practical advice what to eat and to do and what to avoid!

[@GoldenBlaisdale]

Hi Doc great video. Question: Does the Randle cycle debunk the concept of insulin resistance? Others explain the Randle cycle thus: “When a cell is full of fat it will lock the door to both fat and carbohydrate because there is heaps of energy stored in that cell ready for use, we don't need it right now and actually sugar inside your cells is incredibly toxic. So to protect the inside workings of the important cells like muscle cells, organ cells etc the ‘door is locked’ no more fat can come in.… We don't need any more sugar so we are locking the door to that sugar too, so it then sits in the blood and starts to pool in the blood which is detectable as an increase in your fasting blood glucose level…. They then diagnose it as ‘insulin resistance’, no, it's nothing of the sort, it's a mechanism by which the body protects itself from damage. The sacrificial lamb in this case is the red blood cells which become damaged by the glucose in a high blood sugar situation.” Is the above what the Randle cycle describes?

[@Technichian462]

Insulin resistance is not a thing in and of itself. It doesnt exist in the way that its there, and can be measured directly. The Bart Kay says it best. “Its a concept”. But its a valid concept, in that we can see results of it physiologically or pathologically.

[@GoldenBlaisdale]

@@Technichian462 this isn’t my area of expertise, though I have been carnivore for five years mostly finding my own way. Only recently have very knowledgeable people got into the space. So in general, I’m not arguing the rights of wrongs but I’m finding the infighting confusing. For me, it doesn’t really matter whether the Randle cycle locks the door to more energy coming in as Bart says. Or if the cell becomes resistant to normal levels of insulin and needs more to push energy into it. In the end like most animals if we eat the diet we are supposed to we will be healthy. Understanding the biochemistry is just interesting. For example, another Bartism is that evolution just hasn’t bothered to turn off our digestive enzymes that digest starches. I think that is just wrong. I don’t think we are obligate carnivore and many people can eat a mixed diet including starchy veg my whole extended family have done so in the past and without those starchy vegetables would’ve starved to death. Most people during the Second World War in the UK would have starved without our ability to make use of plant starches. And although it is only my experience, my mum has just turned 90 and just about everyone in my family from poverty in the Welsh valleys have lived to their very late 80s and 90s none of them were on a carnivore diet. Yet they were all healthy and died of old age. And another example, I turned carnivore as I say about five years ago, I’m 58, so I until about the age of 52 I ate a western diet, though I didn’t indulge greatly in processed food. However, I have drunk copious amounts of alcohol and suffered hangovers, and yet when I had my CAC score measured, my coronary calcium was zero. That’s 52 years on a standard diet.

[@Technichian462]

Very good. I love getting into the science of things. Now, consider this. Heart disease. Plaque build up. Calcium build up. The CAC score is a measurement of built up calcium, under the plaque. But what is causing the calcium build up? Is the calcium somehow attracted to the damage done to the arterial wall? But what about oxolates? Oxolates build up in the body. Oxolate crystals build up, get caught is these damaged areas. Oxolates love to bind with calcium. Could it be then, that the plaque build up is caused by oxolates? If so, there is a larger commonality in heart disease with Plants than with animal products? Many plants contain oxolates, so ergo... The root cause of heart disease is plants?

[@troytmd]

Interesting! In a review of coronary arteries from 80 patients, we found 4 cases in which there were prominent oxalate deposits within the atherosclerotic plaques in coronary arteries. Oxalate deposits were also present in the media of arteries, the thyroid gland, and other organs, but not the kidneys, and the patients surprisingly did not have renal failure.

[@ryanray6215]

[@Emadagban777]

There is a crucial point that needs to be highlighted here which is where all of the excessive free fatty acids come from in the first place. Dr Ben Bikman explained that adipocytes start leaking FFAs when they become hypertrophic, up to 4 times their normal size, as the fat droplet within the fat cells gets larger, perilipin can no longer protect the stored fat from the effect of lipases. Again, it is Insulin that activates lipogenesis and it is carbohydrates that spike insulin.

Wrong. High BMI, obesity and low/no carb diet will have excessive fatty acids peroxidizing so the body must burn em triggering lipolysis.

E.g. how does the Randle Cycle (or inflammation?) cause GLUT4-receptors to stop working or perhaps the insulin receptors stop working? I keep hearing about how inflammation causes insulin resistance but to me it is a big, important puzzle piece to have a somewhat complete understanding, as a layman.

Yes we know some but not all regarding IR

[@erharddinges8855]

[@jberts3141]

My understanding of IR is the more insulin you produce the more resistant you'll become over time. I think more importantly than that simple concept is what we eat and the consequences of that. Take seed oils as an example, they cause a compound called 4HNE which damages the cells ability to respond to insulin it causes fat cells to grow instead of divide until they can't grow anymore and cause disease. A good book for this is "why we get sick" by Dr. Ben Bikman PhD. And zero acre farms has good info on their website under "white papers"

[@my-yt-inputs2580]

Ben Bikman has done a few videos on the Randle cycle since this video was first published. He just very recently did one with Ken Berry which included a short discussion of the Randle cycle. Bikman made a very compelling condition on using an untreated Type 1 diabetic as a perfect example. The untreated T1D will have sky high glucose and will also have sky high fatty acids. Yet because NO(or very little) insulin is present the body will ALWAYS choose the fatty acids for energy even though there are tons of glucose available for use. As soon as you treat with insulin the body will shift to burning glucose. Which brings us back to the Hormone insulin. Which is where/how insulin resistance can effect things. "Construct" or not.

[@uberneanderthal]

insulin's job is to shuttle glucose out of the blood and into cells. the Randle Cycle's job is to protect the cell from glycation and mitochondrial burnout. it is by design that the Randle Cycle overrides the role of insulin, because it is more important to protect organ and muscle cells from glycation than it is the more easily replaceable red blood cells.

eating fats doesn't make fat in the blood (triglycerides) go up. Eating carbs do. This is 100% caused by carb overconsumption. You should always eat fat with each meal, whether it has carbs or not. And there is no natural healthy food that you would want to eat that has only carbs in it anyway. So the people who characterize this as saying not to eat carbs and fat together are wrong. This is a pathogenic state caused by eating too many carbs.

Many thanks Dr. Cywes - it took me a cup of tea, notes and replays but at last I feel I understand what's going on. I've been carnivore for a while but looking at Ketovore. My take away is - add a few carbs to give my insulin a work out but continue with intermittent fasting.

[@asherasator]

Randle et al. proved for decades keto/carni diet metabolism creates type-1 diabetes, and turns type-2 into type-1, regardless if glucose numbers are lower because of low/no carbs the pancreas and hormones are slowed or stopped. Cywes is 100% wrong and anti-science. He avoids calling glucose to pyruvate ketone, yet uses ketone for fat metabolism. Glucose becomes alpha-ketones pyruvate by CoA (coenzyme A) then ATP (adenosine triphosphate) cellular energy by glycolysis/fructolysis. Glucose make more ATP per molecule than any other source. Mitochondria respirate slower burning fat [lipolysis/beta-oxidation] ketones and make less energy so BMR (body metabolic rate) must rise to try and keep up with what glucose does easier.. The body makes ketones 24/7 with any diet.

[@carlosvangrinder3754]

Excellent video, thank you.

[@alexakalennon]

Love that nerd out Thanks for the effort

[@CarbageMan]

So, when you hear people say fat causes insulin resistance, they're referring to Randle's incorrect assertion, and thus, they're wrong. Additionally, excess protein may not seem to be problematic, but it does indeed cause high blood sugar in someone who already has chronically high insulin. This tells me that it's very important to consume an appropriate amount of protein, of an optimal (animal) type, and even more important to make that protein source fatty or accompany it with fat, to avoid overproducing glucose. What I find interesting about this is that many carnivore advocates claim that gluconeogenesis is on-demand. This seems to indicate that is not true. I started my diabetes-reversal journey by extended fasting and eating a moderate-protein ketogenic diet, which many would say is appropriate, in context. However, I believe I did not get enough protein (I developed a hip issue) and went the other direction-to a "ketovore" diet, with (truly) intermittent 36-72 hour fasting on some weekends. I believe I've corrected protein issues, but my blood sugar isn't ideal (it's still below "pre-diabetic.") Now I'm trying to figure out how to best adjust. I'm doing more weight training now, so I presume that will help. I suppose I should be eating 3MAD with more level amounts of animal protein, and including fiber, to throttle gluconeogenesis. My preferred way to do that would be to accompany meat with cruciferous vegetables (which is more or less what I do, but I don't alway eat the veg.)

[@asherasator]

Glucose made by gluconeogenesis does not trigger insulin and IGF-1 growth hormone production. In lipolysis/beta-oxidation mitochondria respire slower than by glycolysis/fructolysis and requires higher BMR (body metabolic rate) for fat/protein pathways to be main source for ATP so body surplus is used and weight comes off as glucose/pyruvate made is looping to maintain higher BMR, so the body just can't doing it all properly. That's why keto/carni low/no carb should be short term and that's how they were initially designed to treat obesity and epilepsy. Cywes is focusing on irrelevant details as glycolysis/fructolysis makes alpha-ketones pyruvate to ATP very easy. The alpha-ketone pyruvate is key in insulin, IGF-1 and hormone production including glucagon. These hormones have many more functions than just glucose. The whole point from Randle et al and many others decades later is that long term lipolysis/beta-oxidation [keto] and gluconeogenesis disrupts the entire metabolism and hormones and creates diabetes and "Metabolic Inflexibility" [not able to go back and forth from glycolysis/fructolysis to lipolysis]. Only in a balanced diet of 60-70% carbs and the rest proteins/fats in proper calorie intake can that be prevented and one considered metabolically healthy. Cywes is 100% wrong and trying to frame Randle into his subjective ideology of quackery and anti-science.

So interesting. You don't even need to understand the Randle cycle to recognize that competitive athletes (and their coaches and trainers) don't actually need to replace every calorie they burn during a competitive event. Yet they continue to force sugary gels and other crap into their systems at a rate of 100-200 calories per hour, often puking and bonking in the effort. It's hilarious to me. I spent the last dozen years as a recreational (not competitive) endurance runner who learned this from a book written by Phil Maffetone (a pioneer in this area) years ago, and I even had my fat-burning capacity measured in a sports medicine lab at a university. If a weekend warrior like myself can burn fat at very high levels during hard efforts, imagine what a highly trained, professional runner or cyclist could do if their coaches understood what you're describing. (A small number of them do know this, but they are considered a bit kooky in that world.) In my less-trained state, a marathon or a long trail race is very hard for me, and it takes me much longer to finish than a competitive athlete -- and yet, I can do it without ingesting a single calorie for hours. No gastric distress, no bonking. But competitive athletes are brainwashed into thinking it is not possible to generate your own energy during hard efforts. Their coaches calculate how many calories they're going to burn at a certain power output and make their athletes set timers to guzzle down an equivalent amount of sugar every twenty minutes to prevent... sudden death? (ha). Sure, some supplemental fuel might be needed or helpful at times for top-level performance, but the belief that you have to replace every calorie burned in real time is nonsense. This is why some marathoners and triathletes can have visible fat around their midsection despite training for 30 or 40 hours per week.

The bit at the end got me thinking that what he means is a carnivore diet(or poorly monitored/structured keto) as advocated by some as "eat plenty of protein" (ie 2-300g), especially as you get older etc but for a lot of people they end up eating way too much protein and not enough fat, leading to the excess protein being converted to glucose, and if you are already insulin resistant it's no different than eating carbs I suppose...I did carnivore for 3 months and my blood sugars went up because I did this style...If I ever went back to it I'd be sure to cut it back to a 20%P to 80% Fat kind of ratio... As he says though, it's probably an incomplete picture still and in 10-20 years they'll be laughing about all the stuff we don't currently know about (yet to be discovered hormones etc)

Need to check detailed bloodwork

@@monetaryjack1705 I think the issue is also that we don't consider the fat% in our diets coming from our body fat. When eating less than maintenance, our body burns a good portion of our own fat in addition to the dietary fat. Lower protein would be more warranted when maintaining weight, since it is not contributing.

[@erharddinges8855]

Yes,we always should think of long run consequences, and a keto diet propably creates other new problems.

[@Damudean]

I didn’t think the Randle cycle said fat causes I thought it explained too much sugar causes the problem when we have fat as well

[@GoldenBlaisdale]

Because most people in this space heard about the R. Cycle via Bart Kay. And Bart in his very ‘know all’ way rubbishes the idea of insulin resistance as a concept and uses this paper mistakenly to assert ‘the science is settled’ when Randal was unaware of other key components like glucagon. In other words Kay has muddied the waters and given us wrong conclusions.

[@runemartinguldberg9056]

Would Cywes read Randall’s paper if Bart Kay didn’t bring them.

[@robertcywes2966]

Nope. He blamed fat

[@GoldenBlaisdale]

@@ChappySinclair What you said in my opinion fits with reality. Our bodies have complex enzymatic machinery to break plant starch into glucose. Kay says this is an evolutionary over site. There in you see his biased reasoning, denying reality to ‘prove’ we are obligate carnivore. Our ancestors if they had had a successful animal, kill and plenty of fatty meat and by coincidence came across starchy tubers, or sugary fruits. They would most certainly have eaten them together. One of the missing keys that I used to heal myself was fasting. Fortunately, Jason Fung was one of the first in the low-carb space, but focused on fasting. And fasting is ancestrally relevant because there would not have been an absolute guaranteed access to food at all times. I think one of the big mistakes, when thinking about the best diet for human beings, is not taking into account the not eating part of the process and it’s benefits e.g autophagy.

[@xmenotux]

@@GoldenBlaisdaleI disagree. Both Dr. Cywes and Bart Kay agree the Randle Cycle is true. They may or may not agree on some of the nuance of why, but ultimately that's less important.

[@CoachStephen]

I cant believe how long winded this is to explain a very well known aspect of type 1 diabetes called 'glucagon dominance' many things are examined once you simply learn that phrase. People on keto or carnivore have low levels of insulin and when eating protein you see a small bump in blood glucose due to glucagon (not the protein) and seems Robert does not know this either. It is common knowledge but he presents it like he has discovered something

[@danielbarr9795]

So …. I am type 2 diabetic , using insulin , and have been on carnivore for a yr … I am still getting high glucose spikes …. I still have to take insulin every 2-4 days to get my levels down to a good range as my readings gradually creep up …. I am however using about 20-25% of the slow acting insulin I hade to use before I started on this diet Is there any supplement or protocol I should try to fix what is going on , or should I just keep doing what I’m doing and eventually it will heal?

[@danielbarr9795]

Love to know how to move forward with this issue …. So many of my other issues have healed up but not this …. I’m 62 btw

[@daleval2182]

​@@danielbarr9795I'm 64 , I still need insulin on Carnivore too but much less, the dawn effect, our liver dumps glucose at pre dawn, around 4 am, then it slowly falls if fasting, I use a little slow release before bed, fast till 6 pm, eat meat fats, and often need little to no rapid insulin again, I believe time to get our weight normal is only thing that will stop this, good luck

[@ekondigg6751]

I think the word "cycle" is a bit of a misnomer which tends to lead people to a wrong understanding. It's not like, say, the Krebs cycle where we see a circular chain of reactions. It's more to be thought of as explaining an either/or function where cells will either (almost) exclusively use fat for energy or (almost) exclusively glucose, but not both at the same time, except in exceptional circumstances.

[@mrrpgswe8931]

This was just beutiful. Please, do not hesitate to do more ninja nerd hardcore stuff. I Just loved this one. As a layman I have wondered how the heck researchers could empirically identify the electron transport chain, the compartments and all that jazz. If someone could explain how thing like thas was identified it would be a real treat.

[@sweetlife5670]

The mistake is actually at 6:37 and he says glycogenolysis rather than glycogenesis.

[@erharddinges8855]

Glycogenolyses is glucose from glycogen and glycogenesis is glucose from proteins. right?

[@desmomotodesmomoto2033]

Makes sense.

This is supposed to demystify but I think I couldn’t follow this at all. Need some graphics or something.
