Heart of the Matter: Higher LDL on Keto Does NOT Mean More Plaque.

[@KenDBerryMD]

Bravo! Chipping away at that paradigm…

[@makaisenki]

Less of a paradigm and more of a secret society pyramid hidden in plain sight. My phrase I've been using for a year now is "If you don't use it, it will abuse you" LDL is an example of this. I believe it circulates not being used until it over stays its welcome, gets oxidized and then becomes an issue. Since keto/carnivore uses lipids as energy, we use it therefore we are not abused by it.

Nick, this is fascinating. I’m a physician and have always been curious about the biochemistry on metabolic health. I was on a ketogenic diet in college (about 12-13 years ago before keto was mainstream) based on papers I had read. I was lean and my LDL was also the highest it had ever been, which spooked me. I knew LDL was correlated with heart disease but was curious how it would affect me…obviously I didn’t get a CTA of my coronaries…and stopped the keto diet from fear. Not to mention, the biochemistry and what we learn in medical school support the “badness” of LDL with its coorelation with heart disease. So learning about your work is so exciting as it addressed a question I had about leanness, ketogenic diet, LDL, and heart disease. Preliminary, yes, but we can learn so much still ❤️!

[@MichaelWDietrich]

I'm not lean at all ( BMI 34 though rapidly decreasing weight trough low-carb diet), but my bloodwork has shown the same triangle since I went low-carb and controlling my keto status. I've got bloodwork from before where ldl and hdl were in the recomended corridor. First Keto bloodwork from only 3 Months into keto shows nearly doubled ldl and 25% + in hdl where tryclycerides stay low or even dcreased (a not realy significant) bit. This (quaterly measured) trend stayed for the following bloodworks. Though not so dramatic (no doubling of LDL anymore ;-) but still slightly rising LDL while at the same time losing more weight. If I wasn't convinced that Low-Carb and keto had already done a lot of wonders to my health, that LDL-Values would have scared the hell out of me. Glad to find your study.

[@patl3854]

I am in similar situation, only I am female, older, and on keto/low carb for about 5 years. I was quite overweight, lost weight, and everything was great except LDL. Statins are worse than useless; they are harmful and the studies supporting their use are biased. Dr. Nortin Hadler's books on how we are all over-tested and over-treated are excellent. I especially appreciate his book: Rethinking Aging: Growing Old and Living Well in an Overtreated Society. For the younger folks: The Last Well Person, and Worried Sick.

[@MichaelWDietrich]

@@patl3854 It depends a bit on what you mean by "older" (I'm 60 and my doctor didn't even dare to offer me a statin prescription - because he knows my lifestyle). But in fact, according to the manufacturers, statins are contraindicated for people over 70. Because "the side effects outweigh" the "possible positive" effects. On the other hand, various studies show that statins can indeed reduce total cholesterol and LDL. BUT: the really important values ​​ - number of LDL particles and - amount of particularly harmful LDL

High cholesterol is not associated with heart disease, plaque is. However, statins may work partially by reducing inflammation, but il also comes with a host of problems including sexual and cognitive. It depletes the body of CoQ10. The problem is not LDL per se but small, dense particles of it. If the majority of your LDL is not those particles, you're fine. Quoting ''Small dense LDL is the most *atherogenic* subtype of LDL, which means that it is more likely to leave fatty deposits in the blood. Having fatty deposits in the blood means that a person may be at higher risk of developing certain conditions, such as: heart disease. obesity.''

Here is a ChatGPT summary: - The data presented are pivotal but preliminary and cannot be ignored. - The study, published in Jack Advances, investigates the effects of carbohydrate restriction on LDL cholesterol and atherosclerosis in lean mass hyperresponders on ketogenic diets. - 100 lean and metabolically healthy individuals on ketogenic diets were followed to measure plaque accumulation in their coronary vessels using state-of-the-art coronary CT angiography. - The keto group had significantly higher LDL levels (average 272 mg/dL) compared to a matched control group from the Miami heart cohort (average 123 mg/dL). - Despite high LDL levels, the keto group exhibited no increase in plaque compared to the control group. - There was no correlation between LDL cholesterol levels and total plaque measured by coronary CT angiography. - The subject with the highest LDL level (591 mg/dL) in the keto group had a zero plaque score. - The study raises questions about the absolute risk associated with high LDL cholesterol in metabolically healthy individuals on carbohydrate-restricted diets. - The lean mass hyperresponder phenotype shows a unique metabolic response to carbohydrate restriction, leading to high LDL, high HDL, and low triglycerides. - The study suggests that more research is needed to understand the mechanisms and risks associated with this phenotype. - The data are preliminary and will not change current guidelines immediately. - The study acknowledges that the lean mass hyperresponder group differed from the control group in non-LDL parameters like HDL, triglycerides, and BMI. - The study emphasizes the need for more research to understand the metabolic signature and underlying physiology of lean mass hyperresponders. - Main message: Despite high LDL levels, lean mass hyperresponders on ketogenic diets did not show increased plaque accumulation, challenging conventional wisdom and highlighting the need for further research.

Only one CT Angiogram were TAKEN by the Feldman/ Budoff LMHR studied peoples. ONLY upon reporting of CAC and Softplaque by LMHR's second scan will we know the effects of this High Fat Lifestyle. All we know now from the first Heart Scan by the n=100 LMHR is that appx 30 of them has very severe TPS total plaque score. Also the LMHR Study will not follow MACE(heart and stroke events) by the LMHR.

From the LMHR Study. "The matched mean age was 55.5 years, with a mean LDL-C of 272 (maximum LDL-C of 591) mg/dl and a mean 4.7-year duration on a KETO. There was no significant difference in coronary plaque burden in the KETO group as compared to MiHeart controls (mean LDL 123 mg/dL): coronary artery calcium score (median 0 [IQR: 0-56]) vs (1 [IQR: 0-49]) (P = 0.520) CCTA total plaque score (0 [IQR: 0-2] vs [IQR: 0-4]) (P = 0.357). There was also no correlation between LDL-C level and CCTA coronary plaque." THIS SHOWS VERY CLEARLY that at the median====> 50% of age 55 Americans on the SAD standard american have no Heart Plaque. The LMHR n=100 did NO Better at the Median.

Engineer here. In short there are two fueling modes of the human body, ketone (fat) and carbohydrates centric at the two extremes. LDL's impact on the body is different at each end. As fat (LDL) is the primary fuel during ketosis, it makes sense that there will be more LDL and a corresponding rabid burning/turnover of that fat. Those different paradigms seem obvious to me. So, what needs to be determined are the in between responses by the body. For example, comparing 70% Fat/ 10% Carb/ 20% Protein versus 50% Fat/ 30% Carb/20% Protein versus 30% Fat/ 55% Carb/20% Protein. For the Carb a factor is naked carbs (which we already know is bad) versus Whole food Carbs. For Fats, Saturated fats (which I suspect are unhealthier the more Carbs, but not so much during ketosis) versus Poly-Monounsaturated fats. - Simple non-medical/molecular biology language I think most should understand. 😇 Good video.

[@clinhart]

Engineer here, too. I am aware of at least 4 types of fuel for cells, and all of those fuels can be transported by blood: These are glucose, ketones, cholesterol and glutamine. So, there is quite some redundancy in that system. If one type of fuel is inhibited or not economical due to diet, the other types of fuel will probably be elevated. Which explains higher LDL on a ketogenic diet for some people. Other people's bodies may prefer to produce more ketones for example to replace glucose. I am currently temporarily testing a cholesterol-lowering drug ( ezetimib ), and preliminary results indicate that my glucose level is elevated and ketones are still quite high but a bit lower than without the drug. The drug seems to also inhibit conversion of fat to ketones by blocking a receptor that cells need to get fat into the cell. Which indicates that the body replaces LDL and ketones by glucose from gluconeogenesis. Possibly, glutamine is also elevated, but I cannot measure that. The connection of those 4 internal fuels to food also have several pathways and degree of freedom: Some amino acids can be converted to glucose. (gluconeogenesis from protein) Some amino acids can be converted to ketones. (ketogenecis from protein) The amino acid glutamine can be used directly. (is converted to glutamate at some point, possibly in the receiving cell (?) ) The glycerin component of triglyceride fat can be converted to glucose. (gluconeogenesis from fat) Fatty acids can be converted to ketones. (ketogenesis from fat) Fat can be used to build cholesterol. (together with protein I guess) Glucose and fructose can be converted to fat. ( for storage ) All of this is more redundancy than most mission critical computer systems have. Which is awesome.

Simon HIll once said that the main function of LDL particles is to actually carry triglycerides, which is fat for fuel. so it makes sense that in the absence of carbs, we need to use much more fat as fuel, hence more LDL particles. and if we re-introduce carbs (like oreos), we need less LDL particles in circulation. however, why are these higher LDL-C levels not leading to more atherosclerosis? that i don't know, it's very surprising.

Because it is not a chance in hell that ldl cause plaque build up (plaque is rapid blood cloting, in exposed areas) when the artreries don't heal properly. They consist of very little ldl compered to other things that float in the blood stream! Like fibrin and macrophages. The result of cloting is an arterie disease, and have nothing to do with ldl or the cargo cholesterol esters!

Two comments...first, it's generally accepted that oxLDL is the problem, so higher LDL should not = oxLDL in the presence of a healthier lifestyle (you mentioned metabolically healthy--which is unfortunately a rare unicorn these days). Second, just having seen this video and briefly looking through the study, I didn't see specifics on the other macros in the diet. Keto is all about the fats, but many think that this means lots of bacon and cheese instead of macadamias nuts and avocados - this can certainly make a difference in outcomes.

Nick, the language used throughout the video and paper (though it hints to the correlation in paragraph 1) is "LDL", but I'm assuming in this cohort that increased LDL means increased ApoB as well?

I recently had an email exchange with Nick Norwitz about this topic. He seems like a very open minded person. He basically stated that the Keto diet does NOT necessarily mean a high meat diet. His exact words: …. “a ketogenic diet can be low in meat and high in fiber, it that's one's preference” I think this phenotype of LMHR is very unique and very important to study. But let’s be clear. At this point this study is not necessarily a thumb’s up for a carnivore diet.

This is indeed interesting stuff, congratulations on getting the study this far! A couple of criticisms/questions would be: 1. A trial of N=100 seems relatively small for generalising about atherosclerosis, and 5 years is still relatively short 2. I'm under the impression that there is a threshold (around 80mg/dl) for LDL that marks the point at which we might expect progressive atherosclerosis to start to occur. Since both groups were significantly above that level, would any difference between them be negligible anyway? I.e. how linear is the response to LDL levels in the general population. 3. There continues to be a danger in the communication of this research that results that apply to a specific phenotype (that is not particularly representative of the population in general) might be applied to the wider population. Since this feeds into the "statins are a trick of big pharma" conspiracy theorists, there is potential for misuse of your research to beat a very different drum. 4. There are a whole bunch of questions about comparisons between the two groups in the trial - almost by definition a group that sticks to Keto for five years is much more aware of their body, and likely to have different exercise and activity routines as a consequence. 5. Similarly, the types of fat being ingested are known to have effects on plaque formation, so there are a lot more questions around diet composition beyond simple carbohydrate/protein balance.. None of these questions should take away from the hard work and interesting science that you're doing here, but as you say, there are a lot more questions to be answered...

[@nicknorwitzPhD]

(1) n-value isn't nearly as important as the question and methods. And 4.7 years is longer than many trials looking at plaque (2) Two words: dose response... idk where you got the 80 mg/dl threshold, but 123 mg/dl and 272 mg/dl are two very different "highs" (3) We communicate the research with appropriate caveats. There will always be those who seek confirmation bias, on both sides. The alternative is to shield the public from data. I don't like that alternative. We will continue to do our best to communicate responsibly. (4) Addressed in the video. Please watch again. (5) Please feel free to elaborate. Please cite studies, for example, showing dietary saturated fat promotes plaque development independent of changes on ApoB/LDL

[@llicit1833]

Another issue I've seen raised is that plaque accumulates first in the arterial wall, and only after a long time does it appear in the lumen. And the lumen is where the imaging used in the study is looking for plaque. Not sure how valid that criticism though

[@weksauce]

11:00 it's just the same human ignorance: thinking that because X and Y are correlated + a plausible mechanism by which X COULD cause Y exists ... means that X MUST cause Y. In this case, that elevated LDL must cause CVD because high LDL and CVD are correlated.

[@williamhightower4940]

I have been moving to what one might call Keto after 10 years of pricking my finger to monitor my diabetes. I learned over that time what raises my blood sugar. In my push to finally get off weight to prove that I can loose weight without weekly injections I started moving toward keto, with a 18day stay in the Hospital that caused me to really get motivated to get the weight off. I listened to my heart doctor, and read about the keto friendly south beach diet. It's like Keto light. I ended up more carb restricted, not quite carnivore. It's working, A1C looks normal. I was able to get off one diabetes med. But, my triglycerides and LDL went way up. My HDL really didn't move much, actually is below "normal". This is my Puzzle. I played over and over in my head what my doctors said. They are concerned about the triglycerides and LDL but they want me to continue with my diet. I have lost around a 100lbs and probably could loose another 100 to get to a healthier weight. I'll see my 2 doctors in 6 months, and hopefully I'll have lost another 24-30lb or so. One question I do have is what is the minimum dose of Oreos for lowering LDL and maybe Triglycerides? I know silly question, it is counter to me trying to put my Diabetes into remission. Sorry I don't know to have a short comment in this side of KZbin.

[@olafstorbeck4777]

I'm not a physician, so take it with a couple pinches of salt: To readjust a metabolism after decades of derangement needs time. Definitely don't ad the Oreos. The raise the Triglycerides and lower the HDL. If you need another 100 pound to loose and you lost already the same amount, keep going. HDL would rise with exercise, but if you are 100 pound overweight, be careful with your joints, swimming would be great if possible. I did also intermediate fasting, e.g. omad. I'm mid-fifties, was on overweight (barely not obese) and had HBA1C on 5.9, so insulin resistant and not yet pre-diabetic. I lost 35 pounds. But to restore insulin sensitivity and get a healthy metabolism takes probably years. I for myself decided that I keep track of Trig/HDL-C being low and ignore LDL-C on a LCHF. Oh, just another trick. If you can effort it, use a continuous glucose monitor for a month or so and journal your food and exercise. I found funny effects. One day I was trailrunning for 10 km (7 miles or so) in a 24h fasted state and my blood glucose went slightly up. Afterwards I had a keto feast (steak, prawns, broccoli, salad, a bit of red wine) and while eating my blood sugar went down. Especially if you are still loosing weight, you need to consider that you are in catabolism, that fat lost is kind of part of your diet

@olafstorbeck4777 Thanks, the oreo remark was kind of tongue in cheek. No way I could enjoy anything with that much sugar.

HDL I suspect that is genetic, all I ever was able to lower it with a very low fat diet and exercise. This is the most successful at loosing weight of all the diets I tried. It will be interesting in 6 months with another 25-30lb off. I expect i have another year and a half to get to a healthy weight. I will stay keto once I get there. I walk more and move more at work for most of my exercise. Knees are not so good, but way better than last Thanksgiving.

LMHRs have very high LDLc values on a keto diet. An interesting questions would be, what happens to these people on a high-carb, low fat diet? Will they have a unique response to an anti-keto diet?

Interesting video! I started doing keto around the same time with my friend who is 17 yrs younger. His LDL level elevated drastically after 1-2 yr, but for me, my LDL level never elevated, in fact it decreased a little. Anyway, after a more detailed lipid profile test, it was found that his LDL-P level was quite low. My LDL level has never been high all my life, even when I was eating lots of rubbish like high sugar/carbs/seed oils. I suspect maybe it was due to my body’s inability to metabolize fructose (according to tests). None of my siblings were overweight, and so was my mom who ate all day with 0 exercises, but was still able to stay very slim. However, not being able to metabolize fructose is like a double edge sword, it kept me from getting overweight, but at the same time, it gave me blood sugar spikes that elevated for hours from consuming fructose, much worse than glucose.

Excellent talk. Ty. My wife is a LMHR. She went from a total cholesterol of 7 mmol/L to 16mmol/L upon starting 95% carni/low oxalate diet a yr ago. Since leaner folk might be more likely to eat high oxalate foods such as spinach salads and green smoothies, she would like to see prior oxalate consumption explored as a potential contributing factor to the LMHR phenotype. Over the past year on 95% carni / low ox, she has been constantly expelling calcium ox crystals via urine, nails, eyes and skin. She has just started to develop cholesterol deposits under her eyes (xanthelasma). Is it possible to do an analysis on the LMHR group using prior ox consumption as a variable? Or even better, CHANGE in oxalate consumption (a potential measure of oxalate dumping) when they switched to low carb (ie she went from 2000 mg to 70 mg of oxalate consumption /day when she went low carb. Oxalate dumping causes intense inflammation. Inflammation is one potential cause of CVD is it not? She appreciates your continued hard work in this area.

[@stingrae789]

One thing I feel may be understudied as a result of focusing solely on the phenotype is those of us who don't have an LMHR response to ketogenic diets. I feel like this happens often for example any research on coffee/caffeine is near meaningless to me because I have no reaction to caffeine. For example my medical aid has a program that actively rewards people for 'healthy' food purchases. Fatty meat and red meat are NOT an option, full cream is excluded, butter is excluded etc. But this is because the pervasive idea is that fat itself is still harmful. I'm not lean at the moment but when I was my ldl/hdl and trigs were very good (compared to the standard set) and yet my diet was the complete opposite of what was recommended. But I can't actually be rewarded for my good ldl/hdl/trigs because the criteria is food based not outcome based. Now obviously the biggest reward is my own health and wellbeing but I think there needs to be pushback against making food choices demonized especially when there's no real evidence to support this approach.

You could use me as a paired control for your studies. My HDL and trigs consistently meet the LMHR criteria but with my WFPB diet my LDL-C is in the “healthy” range for the general population.

Having been immersed in the carnivore community for the passed nine months, a preponderance of carnivore testimonials site their LDL-C and HDL-C as having gone up and triglycerides having gone down. I’m now convince that, for humans, Carnivore = homeostatic human = LMHR. It is in the context of a sickly world population, fueled by more than a century of misinformation about human nutrition, physiology and disease, that the homeostatic human has become an aberration, when in fact, our current environment and state of health is the aberration.

I'm not sure I'm entirely on board with what you say re "Carnivore = homeostatic human = LMHR" for several reasons. However, I do understand the source of your mistrust. That's unsetting and something that needs to be rectified at a systems level. "We" (royal we) have a lot of work to do to build back trust. For now, keep and open mind and don't gamble on your health where you don't need to. Make intelligent decisions. Live well.

Wasn’t high LDL supposed to be an observable marker for an increased risk of arterial plaque accumulation, not necessarily the single underlying mechanism for this accumulate. It appears there should be more than one accompanying condition that the subject must also exhibit for the arterial wall to be susceptible for plaque to accumulate in the first place. In the absence of these conditions is LDL a meaningful metric?
