I'll show my doc and get him off my back about statins... so I had my blood work done on day 3 of a fast.. yikes.. LDL = 287 and total cholesterol = 375!!

I just cannot get my T-Col/HDL ratio to a healthy level and I cant figure it out after three years of Keto. It does not matter what level your Cholesterol is at *(within reason) if HDL is high enough and trigs are low. I got HDL up to 60 for a couple of months but it fell back to 40 again.

THANK YOU FOR ALL YOUR HARD WORK..

At age 70, recently returned from among other joys of my good fortune, a few weeks trekking in the Himalayan foothills, I correctly anticipated further urging from my PCP in the US to take a drug to lower my cholesterol. When I asked, he had no objection to my going to a cardiologist for a second opinion. I'd read essentially nothing about adverse effects, and when I asked the cardiologist, he responded, "Some people think statins should be in the water supply." Okay, that safe! (However, in the ten years since then, I’ve learned that the US had and still has no compulsory system for reporting the adverse effects of medications.) What information was and still is overwhelmingly available regards benefits of statin drugs...which in my particular case and the contradictions in reputable advice, I questioned. Generally benefits focused on lowering "too high" LDL and/or total cholesterol. I went to the internet, where mainstream academic sources also that total cholesterol or LDL was not as accurate a predictor as lipid ratios. With 282 total, 88 HDL, 61 triglycerides, clearly my ratios were great. In light of this contradiction for my individual case, I asked the cardiologist what I should do and why. More about that later, if anyone asks. My point is for years and even now, for a possible genetic study at a major university, I have sought for a subgroup of those you describe-and of which I seem to a member. This subgroup has also taken a statin. (My guess is that lipophilic statins would be most relevant.) To be clear, I'm sincerely not giving advice nor knocking statin drugs, and certainly not for secondary prevention. The devil, and also the angel, is in the details, and here I've found for the first time the details that so affected my own life recognized as existing and and also of importance. THANK YOU!

This was the best explanation I've seen - thanks!

Been trying to understand lipids and how they work ever since I ventured into intermittent fasting some years ago and went on low carb diet more recently - due to the ubiquitous pressure by GP's to take statins once they see the LDL numbers (~4.6 mmol)! This is by far the best and most succinct description (albeit a hypothesis) of how the show (energy system) actually is likely to work that I've come across. Thanks for taking the pressure off my own concern for my ldl numbers - probably categorised as a lean hyper res.

But not sure if I should be worried and try change that. I'm definitely going to try eat more fat to see if that changes... I have tried swapping red meat for fish and white meat, but no difference at all. What's your opinion on that?

Amazing work

Thanks for the great info. I'm so hoping I can get an answer from someone on this. Little background. I'm a 55 year old female. I workout at least 30 min everyday (mixed routines - cardio, resistance, yoga, circuit, HIIT, etc.). I have been on a low carb (non-complex carbs), high fat (although lean meat), very low sugar, etc. I recently received my lipid panel results. I had also asked for an NMR test. Here are my results: LDL-C 159 - VLDL 9 - HDL 46 (mom's HDL has always been low as well), TRIs 46. Total Cholesterol is 211. Although many docs would say I'm 'borderline,' I'm guessing these #s show that I eat more healthy fats. That's true. HOWEVER ... this is the confusing part. My NMR results who LDL-P is 2116 and my small particles are at 776!!!! WTH? If my Tris and VLDL are low, how are these numbers showing extreme risk. I did the MESA calculation and it's 1.4% (using my CAC # in this formula). Thoughts? Thank you so much.

@realDaveFeldman

That is an unusual discordance between LDL-C and LDL-P. Typically, we see LDL-P = LDL-C X 10 plus or minus around 15%. But again, bear in mind from my work that a lot can be impacted by what happens in the days just before your lipid panel. For example, if you consumed a lot more than you typically do in day just before, but were otherwise normal or even lower calories in the days before that, it could result in that discrepancy. You may want to consider retesting and simply trying to keep to your staples, not eating too much or too little, and not doing anything too unusual with sleep or exercise (which again, can also impact these numbers in the short term).

I'm going to really miss your Covid video discussions. Maybe you should explore hosting them on another platform than KZread that does not censor content because we really need to hear what knowledgable people in the low carb community are saying about this important issue that is on everyone's mind.

@vasenpolvi -- right, as I'd expect given how much fasting is integral to the model. You may want to check out my presentation from last summer here: kzread.info/dash/bejne/oXiKutRxd6m4gc4.html

As you are continually refining this presentation, I believe that the level, transportation mechanism, and role of NEFA could be improved. In addition, Dr. Volek's finding of higher (healthy?) inter-muscular fat for highly trained LCHF athletes should be discussed, especially in relationship to higher (unhealthy?) inter-muscular fat deposits in non-trained obese couch potatoes. To me, the higher inter-muscular fat in athletes fits well into your Fed-Ex energy distribution model, as a delivery to a shed with much closer access to the energy demand. Additional graphics of daily energy distribution (energy potential mentioned) would also be useful. Most people (IMO) don't really get the contribution of de novo lipogenesis in this process. A graphic of the daily energy contribution during an extended fast for a 1500, 2000, and 3000 TDEE individual would be useful. If everybody's basic carbohydrate need is around 120g per day, I find that easy to convert to 5g per hour, which also ties closely to a 100 blood glucose level of 5g of glucose in 5L of blood. (Not exact values, but notionally accurate.) Next, there would be a minimal energy contribution from protein metabolism via normal turnover and autophagy. But then the majority of energy would be provided by fat/ketones. The part of this model which has not been well described (IMO again) is the theory of the limitation of fat release by adipose tissue. The best attempt I have seen so far has been from Richard Morris, but in light of extended fasting results from lots of people over the years, I still find it a questionable hypothesis.

So the model is useful to persuade lean people of the validity of a low carb lifestyle and calm their worries about high cholesterol?

My grandpa recently passed away. He'd been plagued with "high cholesterol" most of his life; even had his first bypass at 50. Anyway, my sister came to me raging the other day about my poor low carb diet, saying all her highly intelligent university professors had stressed the facts about high LDL being unhealthy. She "doesn't want me to end up like our grandpa". At our funeral, our dad spoke highly of grandpa's remarkable health. Despite his heart problems, he lived to be 90, while all his family had died before the age of 70. He firmly attributed this fact to him having quit smoking and alcohol altogether, in addition to constantly being out and about; physically active. I really miss my grandpa. He was one of my best friends. He lived the final years of his life eating little else than sausage and potatoes. Everything he had of wealth, he gave away. A truly extraordinary person. All of my memories of his life serve as a monument to fulfilment in life through experience and trust in family and society.

That's a very interesting story, Marie. Thanks for sharing. :)

When a multi variable problem is being analyzed, a focus on one variable with a preconceived idea can skew the conclusions. That is what I see in the ldl research.

I can´t say that I understand your hypothesis completely, but I guess maybe this comparison would be good if I understood it: LDL is like red blood cells and scarcity of fat is like scarcity of oxygen, so we all know when oxygen is at low concentration, then the body will make more bloodcells in order to get the few oxygen it gets more rapidly to the cells and in the same way the LDL gets produced more to go to the cells when there´s not a lot of fat intake or supply. I would say, and I don´t know if you have controlled for this, but if we are talking about lean mass hyper responders you also have to controll for stress levels, especially cortisol, because if there is more cortisol, the body will go into a more catabolic state and therefore the LDL will be increased and the blood sugar, but sugar will go up, but the sugar maybe more in the adrenalin response and not so much on a low carb diet with chronic stress. Now, a lot of very fit people are doing a lot of sport, which is putting the body under a certain amount of extra stress which could also lead to higher levels of LDL. But, a lot of very traumatized people who are in chronic stress and maybe lean maybe not would also respond in that way. I´m not saying, that sport therefore will make people sick, because stress can be a good thing, if it is tolerable to the body, we dont know that. You see, for lots of undiagnosed diabetics or prediabetics actually sugar no longer is a very good source of energy, because they are insulin resistant, so then their LDL will go up the same way, but again, those people will be at higher risk for having higher levels of LDL that are under a lot of stress, which actually can make the cells insulin resisitant, because the body doesn´t want someone who is already worn out to go and do stuff, it wants the person to take a break. I dunno if I´m making any sense. Also I read an interesting paper recently about Hyperinsulinemia in children of mainly diabetic mothers from 2016 I think. That´s also very interesting.

We're talking about two different mechanisms. To get a bit geeky for a moment, where becoming fat-adapted in a healthy context (typically average weight or lean, metabolically flexible), one has lower hepatic glycogen stores which I discuss in this lecture. Thus, per the hypothesis, they are more likely than not in this context to have higher total and LDL cholesterol due to trafficking more triglyceride-rich lipoproteins such as VLDL, which is typically the precursor to LDL. However, *within* this fat adapted context, one can likely overconsume fat and drive down trafficking of VLDL since there's an introduction of chylomicrons alongside insulin, thus less lipolysis, higher leptin, higher T3, etc. In other words, there's technically two major contexts we're discussing for the most part, one is generally in the longer term (fat-adapted lifestyle or not), the other is short term (existing status of insulin and caloric load over the last few days modulating fatty acid trafficking demands).
