No more myths. Saturated fat and keto diet

[@mikeg5413]

My whole way I view LDL has changed. I don’t believe a word that they say about it and don’t fear it … to the point that I don’t even care what mine is. So many of my health issues have been resolved since going on keto that I will never trust our medical & pharmaceutical industries ever again.

[@oliviaedralin1436]

Feel the same way!! I went on a Keto / low carb 4 months ago to resolve weight loss initially,,,, then I got a CMP 14 -Lipids couple days ago,,,, And my cholesterol went up 215 ! My doctor freaked out and had the medical assistant call me. Advised that I ease out on red meat! Also I have to add grains. 😵‍💫 Eating lots of grains that turned to sugar what made me fat in the first place! I’ve gotten rid of inflammations in 4 months, I have no lethargy anymore or fogginess,,, I have never felt so much better!

They lived their lives on a Southern diet, high in fat, eggs, vegetables.their ldl was high, but had no heart disease,or other disease. Just arthritis from old age & working forever. My doctor doesn't believe that would work today as its a different time. My diet is like theirs , but no vegetable oils used, just butter or bacon fat. It seems to work .

I’m a good example. Age 52, I went on keto, but didn’t increase my consumption of saturated fat. All I did was eliminate chips and sugary snacks and added veggies. My hdl and triglycerides improved but my ldl doubled (80 to 160). This is freaking out my doc who now wants me on a statin. But I lost 30 pounds in 3 months. My bmi fell from 28ish to 25 and working on getting into the low 20s (probably another 10 to 15 pounds). I did all of this with zero exercise. I’m now adding weight training to hopefully get my ldl down so my doc gets off my back about going on statin. Hopefully my further leanness doesn’t worsen my ldl. I have no plans on following my docs advice to go on statins. I will do calcium scores every year if necessary (last one was zero). Don’t smoke or drink either so see no need to go on statin. It’s funny that I lost weight and technically eating much healthier but somehow that makes me a candidate for pharmaceutical intervention.

Now I also see yours. I refreshed the page. But that is still totally nuts. 🙂 Aside from that, the main theme of my comment is that to those of us whose cholesterol shoots high it is not due to eating meat and fat and also has nothing to do with being lean, not lean etc. No relevance to any of it. It is in fact caused by burning body fat. So what does this translate to if I may? It has two causes. 1. It is genetics. 2. It is caused by fasting. In other words, just fast and your cholesterol shoots sky high. So what is happening is that keto/carnivore imitates fasting as far as your body is concerned. And of course, also some folks, their cholesterol goes way way higher than the others. Not every one of us is the same. However, it does level off. It won't just keep going up to 10000. So meat, no meat. lean, not lean. So long as you are burning fat for energy, that is the cause. That wraps it up. But what i find rather puzzling is why no experts clearly mention this. Notice how the dude Nick just by eating cookies his cholesterol dropped. Well, that is because when he eats the carbs, he no longer is burning fat. Plain and simple. That is all. Notice with you? When you begin to lose weight, your cholesterol shoots up and when you eat meat, it has nothing to do with it. In fact, if you exercise, fast, eat meat.... Whatever it takes, the minute you run out of carbs your body begins to use fat for energy, your cholesterol shoots up. Nobody actually clearly sees this. It took me a while to see it. I tell you what. Once you get the weight you want, balance your diet and you will see your cholesterol subside. Just eat carbs to keep you out of ketosis and no more. Because if you eat more then you will gain weight. As your body will turn the extra carbs and stores it as fat. My personal opinion is 100 grams of carbs a day is a good place once you reach your weight loss goal. But you just have to experiment.

Great job Nicholas! Saturated fat does not stimulate glp-1 production that leads to insulin secretion but PUFAs do as they stimulate TRPA1 in the intestines a known receptor that stimulates glp-1 production that then stimulates the glp-1 receptor that is a g protein coupled receptor that lowers the threshold of TRP receptors TRPV1 and TRPA1. This leads to the neurosecretion of insulin in the pancreas and hormone secretion in the hypothalamus and pituitary.

[@LawrenceAugust_]

I had to consult ChatGPT for this, lol "The statement you provided contains several elements related to fat types, GLP-1 production, and insulin secretion. I'll break down the components to provide some clarification: Saturated fat and GLP-1 production: The statement suggests that saturated fat does not stimulate GLP-1 production. While it's true that different types of fats may have varying effects on GLP-1 secretion, the relationship is complex and not solely determined by the saturation of the fat. Dietary fats, including saturated fats, can influence GLP-1 release, but the mechanisms are multifaceted and may involve factors beyond just the type of fat. PUFAs (Polyunsaturated Fatty Acids) and TRPA1 activation: The statement implies that PUFAs stimulate TRPA1 in the intestines, which then leads to GLP-1 production. However, the direct connection between PUFAs, TRPA1 activation, and GLP-1 secretion is not universally established. While there is research on the effects of fatty acids on various receptors, the specific pathway mentioned may not be widely accepted or fully elucidated. GLP-1 receptor and G protein coupled receptor (GPCR): The statement correctly mentions that the GLP-1 receptor is a GPCR. Activation of GLP-1 receptors can indeed lead to various physiological responses, including the modulation of other receptors. TRP receptors (TRPV1 and TRPA1): The statement suggests that GLP-1 receptor activation lowers the threshold of TRP receptors (TRPV1 and TRPA1). The intricate interplay between GLP-1 and TRP receptors is an interesting concept, and there is some research on the interactions between gut hormones and TRP channels. However, the details and mechanisms may not be as straightforward as described. Neurosecretion of insulin and hormone secretion in the hypothalamus and pituitary: While GLP-1 can stimulate insulin secretion from the pancreas, the direct involvement of TRP receptors in neurosecretion of insulin and hormone secretion in the hypothalamus and pituitary is not universally accepted or well-documented. In summary, the statement outlines some interesting concepts, but the relationships between dietary fats, GLP-1 production, and the mentioned receptors are complex and may not be accurately captured in the presented sequence of events. The field of research on these topics is continually evolving, and new findings may provide more insights into these mechanisms."

[@susanbeever5708]

@@LawrenceAugust_ very interesting and entertaining coming from a bot. Nice way of starting to think about things. At least there is thinking. The neurosecretion of insulin affects the pancreas via glp-1-> its GPCR receptor the glp-1R that lowers the threshold for TRPV1 on the nerves that stimulate the pancreatic beta cell tissues. The glp-1 RA such as semaglutide folks utilize this. The glp-1R in the paraventricular region of the hypothalamus lowers the threshold for TRPV1 and activation of TRPV1 leads to stimulation of the pituitary to release antidiuretic hormone. This can lead to hyponatremia, hypoosmolality and stimulate TRPV4 seen in active, inflammatory atherosclerosis. Glp-1R lowers the TRPA1 threshold in the hypothalamus that leads to suppression of appetite. This is what the glp-1 RA drugs such as semaglutide folks are so excited about. Fat stimulation of insulin is minimal as anyone wearing a continuous glucose monitor will attest however looking specifically at glp-1 secretion by enteroendocrine cells lining the gut PUFAs stimulate TRPA1. This is seen when people eat the TRPA1 agonist cinnamon also. Capsaicin a powerful TRPV1 agonist is taken in capsules as a diet supplement too but beware it can cause heart failure at high doses. My point is that TRP receptors are key to understanding the relationship between what is ingested and how insulin is produced. We do not yet know the complete answer how glp-1 rises so quickly after eating and there are more TRP channels such as TRPV2 and TRPV4 associated with glp-1 release. When we have hyperglycemia and the cells become resistant to the insulin receptor high insulin stimulates TRPV1 to get glucose out of the blood and into the cell because TRPV1 does not need the insulin receptor. TRPV1 utilizes GLUT4 without the insulin receptor to get glucose into the cell. Who knows this? Force feeding cells glucose-> too much oxidation-> oxidative imbalance while TRPV1 on mitochondria also -> too much reactive oxygen species in excess of antioxidant supply. This all leads to lipid oxidation and inflammatory damage of the mitochondria, cell and other tissues. So not including TRP channels is a disservice to our understanding of the serious metabolic health issues we face.

Reason 4 reminds me of "The Science and Art of Low Carbohydrate Living" by Volek and Phinnek. Iirc they say while in a ketogenic state ingested saturated fat becomes the preferred field (as opposed to your body's stores). So is the reasoning basically not investing saturated fat -> higher LDL to supply energy around. Increase saturated fat intake lowers LDL since now there's less reason to take it from internal sources. This is why the Feldman protocol of increasing saturated fat works?

[@saintwithatie]

Let's examine the confusion going on. Here is what Nick says: *”Here are 5 reasons the saturated fat myth is dead. But, hold on - I should probably define what I mean specifically by ‘the saturated fat myth’ - there are many. In this video, I’m referring to the common perception that when one goes a low-carb or keto diet and their LDL skyrockets, it’s because of the saturated fat.”* Firstly, notice that he doesn’t say “their LDL goes up”, he says “their LDL skyrockets.” He is saying that this skyrocketing - not just going up but SKYROCKETING to levels as high as 600 mg/dl - is driven by BMI, not SatFat, in lean individuals on a low-carb / keto diet. He states “The saturated fat myth is dead” and clarifies the myth he is referring to - that the SKYROCKETING of LDL in lean individuals on a low-carb / keto diet is driven by SatFat. No where does he state or imply that SatFat does not raise LDL levels or that it does not raise LDL levels more than UnSatFat. In fact, he LITERALLY states at 00:53 “LDL can have a little bump on LDL.” At 03:00 in reason 4, he points out that the SKYROCKETING of LDL in lean individuals on a low-carb / keto diet still occurs when SatFat consumption is “low” and UnSatFat consumption is “high.” He also points out that there have been cases where LDL actually decreased after SatFat was increased (although it wan’t clear if these individuals were lean and on low-carb / keto diets). Fun fact: Nick didn’t mention this, but the increase - in some cases, doubling - of LDL has also been in observed in lean individuals who are fasting but not in overweight or obese individuals who are fasting. Their leanness caused their LDL to SKYROCKET, even when NO SatFat or any fat is being consumed - pretty cool! Collectively, the data of various studies DOES suggest that leanness is a driving factor in LDL levels - specifically, that there is an inverse relationship between carb consumption and LDL levels for lean individuals, independent of consumption of ANY category of fat. Nick and Dave may end up being WAY off the mark in regards to both their LMHR phenotype and the Lipid Energy Model as far as the mechanism behind this phenomenon. However, the phenomenon definitely exists and is currently not well explained. But anyway, back to Nick. No where does Nick state or imply that: - SatFat does not raise LDL. He actually states that it does. - SatFat does not raise LDL more than UnSatFat. He does not comment on it either way. - “high” consumption of SatFat is harmless. He does not comment on it either way. - “high” levels of LDL are harmless. He does not comment on it either way. (In this video, at least - he has ongoing OTHER research to assess ASCVD risk in LMHR. This particular study does not look into nor comment on that.) Guys, gals, and everything in between - Nick says what he says for a reason. Listen. He is specific (although not perfect) in his speech, even displaying his words on screen. Yet a lot you miss it, I assume mostly because you’ve made preconceived notions about Nick and his work.

[@marilynmetzger5821]

I have the same question!

[@Part_121]

I'd like (someday) for someone to be able to clear up, at what point are we talking about BMI measurements in LMHRs? For example I started my keto diet at a BMI of around 32, with type 2 diabetes and an LDL in the 60's. 80 lbs of weight loss later, on keto, and type 2 diabetes was reversed but LDL more than quadrupled to the 270s (this while on a statin). I'm now in the triad with trigs of 49, HDL of 98 and LDL of 275 and a BMI of 24. Is there such a thing as a Fat-to-lean-mass hyper responder? The other thing I'll throw in is that, as a kid, I was always extremely lean to the point that it was difficult to purchase clothing that would be long enough, yet skinny enough. No one checked cholesterol in the 1960s, especially in children, so I have no idea what my blood work would have been like back then. Perhaps once a LMHR, always a LMHR, even it you get fat and diabetic? I'd almost rather go back to eating pizza, bread and pasta again, just to relieve the brow beating I get from my doctors, none of whom can even spell lipid energy model. Thank you for looking for answers!

[@melissag3005]

I'm going to be curious in June I get my blood work again, but back when I was BMI over 35 on keto my blood work looked great. I went off keto and maintained bmi 24 but the brain fog and the stiff joints returned so I decided to go on it again and sure enough brain fog gone and joint pain/stiff even only a couple weeks, much less. Awesome to be able to jump out of bed or get out of the car without having to take a moment. I can't wait for this comparison study. I know I have mild calcification just from a generic ct scan of my chest, that makes a TON of sense with my prior life, thankful it is still "mild". I'm also on a cancer med that could raise it. I may not live long, but I feel great. Quality over quantity. Thankfully I know what is on the other side for me so this is all just interesting to watch play out. I'm expecting my cardiologist to freak, but it will be interesting.

That's not rigid. Large LDL can deposit, too. And when they do, they have a bigger load, tho they're not as dangerous as small, which oxidizes easier. But small has less on board... So there's that.

[@pamisntcraiganymore]

I found you recently and really enjoy your content. I kept keto for a long time then careened into a pile of processed carbs I could not get out of. I need inspiration and you provide it with easy to understand information

[@randombitsofreality]

Nick Norwitz, you are incorrect in some assumptions. At 3:35, you said you dropped your LDL eating Oreo cookies, even though they have saturated fat as well. This is a very inappropriate comparison - a 100 grams of Oreo cookies has 6 grams of saturated fat; a 100 grams of butter has 52 grams of saturated fat. That's over 8 times of difference in saturated fat content. You can't say "Even though Oreo cookies have saturated fat, my LDL dropped." You can only say this, if you conducted a second experiment, in which you eat an increased amounts of butter and your LDL drops. And you very much know this will not be the case, unless you eat more calories than you need, which forces the body to store fat and as a result, LDL drops. Therefore dietary saturated fats do have an impact on serum saturated fats, but this depends on caloric intake (and I am sure this is not the only factor at play here). In reality, the small amount of saturated fats in Oreos didn't drive your LDL down. It was the high carbohydrate content (Oreos have 68 grams per 100 gram; butter has 0.1 grams per 100 grams) - this provokes an insulin response and your LDL drops. As I've posted previously, I've conducted this experiment myself, by testing after changing my diet. Eating only plant foods for a couple of days lowers total and LDL cholesterol, eating only animal products (with the exception of fish - they have very low total and saturated fats) drives LDL higher. Again, saturated fat and total fat of consumed foods have very much to do with your total serum lipid profile. However, there are many additional factors at play here, which you don't consider. One example is the mass chronic problem of low vitamin D, which causes dyslipidemia and especially high LDL. In a research paper* it was shown that LDL (also total cholesterol and triglycerides, but not HDL) drops with higher vitamin D concentrations. You don't take this into account with the Lipid-energy model and especially in LMHR studies. And I bet you that vitamin D is just one of many factors, that we don't understand or consider. As far as your observation that some people who consume high saturated fat foods have lower LDL (again, how about their vitamin D status?) - have you considered that the ratio of the lipids carried by the LDL structure can change, and as a result so will the total LDL particles produced by the liver? Keep up your good work. * pubmed.ncbi.nlm.nih.gov/31407792/

[@KenJackson_US]

Do you think high LDL is unhealthy?

[@randombitsofreality]

@@KenJackson_US It's always best to see the research results. My opinion is not worth more than any other person's at this point. If you need to hear it - I don't believe in the LMHR phenotype. Yes, I agree genetics play a role and some people fit nicely in the LMHR phenotype, but I think this is just focusing on a group of people, because it looks nice on paper, instead of realizing this is the normal response for everyone and it varies from person to person. To put it differently, I think that this is the normal metabolic response for a typical human, on a carnivore diet, who has normal BMI, and is not consuming more calories than he needs. Yes, some carnivores with normal BMI have lower LDL, others have much higher LDL, but as I mentioned above, there are many factors to contribute to this - types of food consumed, vitamin and mineral status, thyroid and liver function, mental state of the person, environment, etc. What I think is that high LDL on its own is harmless - the body knows what it's doing on carnivore, because that's historically appropriate food for us. But we must behave historically appropriate as well - movement, sunlight (vitamin D, right?), good sleep. Not behaving properly or abusing substances results in damaged lipid transport particles like HDL and LDL - the latter, being in question, is dangerous if its receptor is no longer recognized and can't be recycled by the liver - it grows smaller and smaller, as it gives off the lipids it transports. The more small dense LDL (sdLDL) particles we have, the more likely we will have cardiovascular problems - they are the ones that lodge themselves in arteries and are covered in macrophages, because the body thinks they are foreign structures that need to be contained. Since measuring sdLDL levels is expensive, we should be very grateful that a relationship between sdLDL and triglyceride/HDL ratio was discovered. The lower your triglyceride/HDL ratio, the less sdLDL particles you have. If I remember correctly, at a ratio of 0.5, only 4% of LDL particles are sdLDL; under 0.3, almost no particles are sdLDL. So what's the worst thing that you can do as a carnivore with high LDL? Eat a lot of sugar at once and damage all that LDL traveling around your body. Eat a piece of cake on your or someone else's birthday and enjoy it. Drink a beer. That's a dozen times per year. But don't eat the entire cake at once and don't get wasted on alcohol. Remember, historically, we have eaten fruits every autumn to get fat - the body tolerates this just fine. But we are not supposed (and we shouldn't be able) to eat all the fruits from the tree at once. Sugar and alcohol allow us to abuse this mechanism. Hope that helps :)

Saturated fat for most people does not raise their LDL, but in the few that do, this can cause heart disease in the long term. People with familial hypercholesterolaemia often develop heart disease even though they have large LDL particles, low triglycerides, and are not diabetic. The difference between those with FH and the LMHRs is that those with FH have had high cholesterol since birth whereas LMHRs likely had high cholesterol for only a few years after going on a low carbohydrate diet that is higher in saturated fat. Not everyone with FH develops heart disease but that does not mean high cholesterol is safe because some smokers do not develop lung cancer and some diabetics do not become blind or lose their limbs. Dietary cholesterol from egg yolks do not raise cholesterol in most people, but a minority of people will hyperabsorb dietary cholesterol and this group also needs to be on a low cholesterol diet.

Agreed. I find the lipid energy model quite convicing for explaining the LMHR phenotype. However, I don't see why this would somehow neutralize the atherogenic effects of high LDL in LMHs. Presumably, LMHRs would have fewer risk factors for heart disease overall but, as far as I know, high ApoB can cause heart disease even without any other risk factors.

[@CharlieFader]

Exactly, while I understand the need for influencers to create clickbaity content, he seems to imply that we were only worried in the first place about the super high LDL levels of a very small subsection of the population and if this not explained by saturated fat intake, that means that saturated fats don’t raise LDL (in general)? All this LMHR stuff, seems to jump from the highly specific to generalizations and back again, and this reveals a lot about the motivation behind these studies. He likes to talk about the importance of nuance, but I don’t think that he’s actually that naive to believe that this is even remotely realistic in the keto/carnivore space.

2:13 - high LDL-C on low SFA diets is caused by endogenous cholesterol + SFA production. It is caused by a) the inability of mitochondria in the hepatocytes to "burn" the substrate for energy, leading to b) mitochondria spilling out a large amount of citrate, which then c1) gets converted into SFA and transported out of the liver in a VLDL, c2) converted into cholesterol vie HMA-CoA and also transported out of the liver via VLDL. For example eating a lot of sugar and activating the Randle cycle both are the primary cause of all of this. So I would really be more carefull here...

Oh come on, be serious. In the Oreos experiment you changed two parameters: sugars and saturated fats.

Also, Figure 4 of your own paper on the American Journal of Clinical Nutrition shows that, for a given BMI, the higher the saturated fat intake, the higher the mean LDL change.

Question: I'm very lean ~10% and definitely am a hyper responder to LCHF. I do not fit the triad pattern, however. Do you often see individuals who are lean and will have their LDL/APOB/NMR particle counts skyrocket - like triple - if doing keto or carnivore but HDL stays low and TGs don't lower (my case they stubbornly hover in the mid 100s)? In terms of risk markers like LP-IR, LDL:HDL, TG:HDL, TC:HDL they look very unfavorable. Other metabolic markers improve of course but looking at the high particle #s in the context of those lipid measures may be problematic. It just struck me as odd that the only marker that seemed to move much at all is LDL and it goes absolutely bonkers. I've had LDL go to almost 600 so I just went back to a primal type mixed diet.

[@johngrener183]

Hello Nick, One thing I haven't seen yet, among those who promote carnivore, is a comparison of why meat fat congeals in drain pipes, but not in arteries. It would be nice to see a study on that. Also, how does hydrogenated fats clog the arteries? Thank you for your videos. They're very informative.

[@Mallchad]

2 reasons. Fairly simple. Fat in drains is just a big lump that cools enough to become solid, it can't mix with water even if liquid so disrupts flow and stuff and can build up over time. In your blood it is small clumps of fat precisely sized by your body's machinery and then packaged in a protein called a "lipoprotein" so it can mix with the water in your blood safely without building up. Second if it did get out for some reason it would be very hot because your body is above the melting point of all fats it will be liquid, then your immune cells can clear it out like any other problem. Hydrogenated fat does not clog arteries no fat clogs arteries, that was an unproven theory that really needs to go away tbh. The thing that causes heart attacks is coagulated blood, a blood clot. The thing that causes narrowed arteries is damaged arteries that need repairing and produce unstable low-density scar tissue. If it is allowed to heal it will become strong arterial tissue and calcified tissue.

[@stargazerbird]

So if you do a very low fat high carb diet as a lean person who is very active what do you see? I would be interested to see what the effect of a lower calorie intake plus high carb does. So far the drop in LDL in LMHR occurs when they either add sufficient calories to be in a slight excess or add carbs. Maybe if you switch it to the other extreme of high carb you still get high LDL during exercise or weight loss. That would further confirm the model that it’s the need to draw down fat reserves for energy that is the cause. Deplete the glucogen stores with a sprint or three and then do a longer run and then test. One confounder in your Oreo experiment was you added them onto a stable calorie intake so were in a calorie excess. How did you know if it was the extra calories or the carbs that made the difference? Fasting and quick weight loss will raise LDL. Never get a blood test on a diet.
