    Before I started keto my cholesterol was 244. At that time I was eating maybe 2 to 4 eggs a week. The rest were carbs in the morning. After starting keto I started eating 3 to 4 eggs a day. So from four eggs a week total to about 21 to 28 eggs. Also I found a guy in the area that raises chickens and ducks. So I buy his duck eggs which I like even better than chicken eggs. The duck eggs are larger than chicken eggs by about 1 1/2 to 2 times the size. After about a year of eating like this I had my cholesterol checked. It’s still at 244 had not budged. And I’m not concerned at all about it because all my other markers improved dramatically. Cholesterol is the passenger not the driver.

    Same. I was interested until he said FH requires statins control. Utter rubbish. I have FH. 19 years ago, my TC, HDH, LDL, Trigs were all so high that I was told to continue taking statins or die within 12 months. But the pains and my avid reading of 'alternative scientific views' encouraged me to stop the medication. I immediately felt better. However, my lipid profile was getting worse and I was worried. Later I discovered LCHF and then KETO. Today, 19 YEARS LATER, I look and feel 15 years younger, my Trigs and CrP are low, I'm no longer even 'at risk'. They think they know, but all they really have are assumptions.

Probably less than 5 distributed yrs out of 15 out on these drugs. Recently, about 7 months ago I started LCHF diet and my trigrocerids level went very low and HDL improved by about 30% with a rising shoot of LDL. Mu question to you os did you have similar shoot in LDL levels. I haven’t been confirmed as HF anytime. Just guessing from time to time by this or the other doctor. Can you please answer my question about ldl rise after LCHF diet.

    Food for thought. I have been low carb for 3 years and dramatically reduced the usual markers such as inflammation, blood sugar, glucose, weight, etc. Yet, my LDL, small particle number and apo B got to a point where my Dr wanted me on statins. In the last 45 days, I increase my soluble fiber intake to roughly 45 grams daily through psyllium, chia seeds and more fibrous vegetables such as eggplant and okra and my total cholesterol went from 220 to 150 and my LDL went from 155 to 93. This reduction was in the last 45 days alone....

    Because normal doctors are generalists. They have to know a little about everything. So they can't always get into the gritty details. Since they don't teach this in med schools, the only doctors who know it are the handful who have the time and interest level to do research on cholesterol specifically on their own time. The average doctor has a shockingly low understanding of diet and nutrition in general. They're great for general paintbrush prediction, trauma, acute conditions, etc. But don't do well with people who don't necessarily match the norm. Such as HFLC eaters.

    Don't you know yourself, that a low saturated diet should at least a little bit reduce your LDL? Why not trying this? But maybe yur doctor knows better, maybe you have a history of heart disease in family, at pretty young age, and he's decided it's better for you to start statins. As for an average "healthy" man, LDL 3.3 is a borderline, with an almost normal HDL, but a high TG, so maybe a diet would help you. But your doc knows better, I believe,

There are quite many of us who like to manipulate these numbers by changing diets and fasting.

I have been on LCHF for about 9 months , lost 20kgs but I think I may be a hyperesponder. Total chol 9.7 , trigs 1.3 , HDL 1.2 , LDL 7.9 , non HDL 8.5 Chol/HDL 8.1 , Trig/ HDL 1.08 , hbA1c 5.1. In this presentation you say that we need to learn more about Lp[a] and PCSK9 .My question is , since making this video 3 1/2 years ago have you formed an opinion about these . From the above numbers should I be worried , do you think I would have modified LDL and what do you think about ceasing statins in my case. As a disclaimer I accept that nothing you say will be taken as medical advice and I release you from any responsibility for any consequences to me.

    Any developments regarding Lipoprotein (a)? From memory, it appears to fulfill a role in collecting up and creating a malleable / billowy partially stable puff around a site of arterial inflammation, so that blood can still flow about and does not tear off this preliminary 'scaffolding" - thanks to those aforementioned mechanical properties conferred by Lp (a) which permit it to yield to the fluid motion ...

    By definition high uric acid levels would indicate a liver that is having to process high levels of fructose and or alcohol. Can't prove directly that it would cause oxidation of ldl but high uric acid levels would encourage insulin resistance, inhibit nitric oxide and raise blood pressure which on a standard diet would lead to higher glucose levels in the blood and increase chances of oxidised ldl.

    I’ve been following this topic for a couple of years now, it is clear that there is considerable disagreement among experts as to whether LDL particle size is a significant factor in atherogenesis. For example, Peter Attia had Tom Dayspring on his podcast, and Tom says that all LDL, IDL, and even most VLDL can get through the endothelial wall. In other words, having mostly large, fluffy LDL won’t save you.

    Hi Dr Sikaris, Very interesting presentation, thank you. I am a health science student aiming to increase my understanding of this topic. I thought I'd post you a question in case you read the responses here. :) I did a short course with Associate Professor Ryan Bradley ND, a cardiovascular specialist who has done a wide variety of clinical and observational research including cardiovascular epidemiology in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort. My question to you relates to your point (at about 8 minutes in) about how the big boyant LDL may actually reduce the risk of heart disease, while sdLDL (solid, dense LDL) increases heart disease risk threefold. So bascially, you're saying its not LDL that causes heart disease but purely sdLDL. I am wondering what you think of the conclusions of this study (which contradicts that point)? "LDL particle subclasses, LDL particle size, and carotid atherosclerosis in the Multi-Ethnic Study of Atherosclerosis (MESA)". www.atherosclerosis-journal.com/article/S0021-9150(06)00259-0/abstract The linked research shows that BOTH small and large LDL are significantly associated with subclinical atherosclerosis and carotid intima-media thickness (IMT) independent of each other, of traditional lipids, and of other established risk factors. It mentions that studies showing that small LDL is mainly associated with greater atherosclerotic risk, do not adequately quantify the number of small versus large particles. Particle quantity important to quantify, as explained in this study: "LDL PARTICLE SIZE: DOES IT MATTER?": www.athero.org/commentaries/comm564.pdf : Quoting that study: "small LDL particles contain substantially less cholesterol than large ones, such that at the same serum concentration of LDL cholesterol (LDL-c), individuals with predominantly small LDL have greater total concentration of LDL particles than those with predominantly large LDL". So what is saying is that there is a significant inverse correlation between small and large LDL particles. It apparently has been demonstrated that the relationship of LDL size with cardiovascular disease is confounded by this inverse correlation of LDL particle numbers, and that actually, once this correlation is accounted for, LDL particle size contributes little to increased risk of CVD. Another issue mentioned that further confounds the inverse particle size correlation mentioned previously, is that many studies use 'gradient gel electrophoresis' to measure LDL. This method determines only the distribution of LDL subclasses or average LDL size (large or small) but it does not quantify the number of small versus large particles. Quantifying LDL-p (number of particles) directly can be now be done using nuclear magnetic resonance (NMR) or using apolipoprotein B (Apo B) - also an estimate of the LDL-P. As mentioned in this study, neither of these methods relies on the variable cholesterol content in LDL particles: www.mdedge.com/sites/default/files/pdfs/jfp_labcorpsuppl_final.6.15.16_0.pdf So I guess I am wondering, other than the fact that smaller denser particles lead to atherosclerosis more rapidly, what the point is on focusing on sdLDL in light of the above research showing that in the long term its not just sdLDL that is atherogenic? If high triglycerides are a good proxy for sdLDL, are they not also a good proxy for LDL fullstop? And if so, is the benefit from decreasing triglycerides also because doing so lowers LDL in general? I understand that oxidation comes into play, and antioxidants are useful, but overall, once LDL is deposited isn't it true that its better to just focus on reducing LDL altogether? Apparently this approach can not only stablise LDL but actually reverse atherosclerosis and coronary artery disease altogether... To conclude, this is a (rough) quote of Dr Ryan Bradley's stance on LDL, which is partly what helped spark my investigation into this topic. "My belief based on the science I have that I have reviewed and that has been going on for now for the last 75 years repeatedly demonstrates that the blood concentration of LDL is the leading risk factor for developing cardiovascular disease and having a cardiovascular event. And we know that from many many large studies in cardiovascular epidemiology where we look at cohorts, we know that in animal models, and we know that drugs targeting LDL clearly reduce cardiovascular events and improve mortality. So in my mind it is unscientific to say that LDL doesn't contribute to cardiovascular disease because we literally have decades of research and hundreds of thousands of people that demonstrate that risk". Full youtube of that is here: kzread.info/dash/bejne/iZN8rLZxiaWeqKg.html Thanks, Talia

    Wow, I got really interested in your video until you started talking about statins which you need to reconsider. I have familial Hypercholesterolemia and statins just about ruined me. I tried several different ones and Lipitor crippled me up so bad with pain that I could hardly get around. Other statins I tried, my triglycerides got really high. Statins are poisons or are you so blind that you don't realize how many people has had severe side affects and a number of people has died. Anyone who recommend statins instead of alternatives to try, is a fool. And there are other things that cause heart disease as well, including too much calcium and age. In fact there are just as many people if not more people dying of heart disease and their cholesterol levels are normal, even well below normal.

    At the end of the talk, he discusses how the LCHF diet reduces small, dense LDL _without_ drugs, with the implication that statins are therefore unnecessary. Remember that this talk was a small part of a larger conference in which the benefits of the LCHF diet were being discussed. So it was an audience for which the implication did not need to be spelled out. And even for those people who don't see a reduction in sdLDL, there is nevertheless a reduction in triglycerides and a corresponding increase in HDL, which itself lowers the risk of heart disease.

    Agree, statins are dangerous, and were killing me as well. I had terrible side affects, while taking Lipitor and Vytorin e.g., joint pain and excessive muscle cramps, overwhelming fatigue, peripheral neuropathy, and cognitive issues. Most have gone away since discontinuing the meds, but some are permanent, but hopefully not progressive. Time will tell. Carbohydrate/sugar and the TG/HDL ratio is, as the professor says are the most important factors. My TG/HDL ratio used to be 7 to 1 on a low fat diet. On a LCHF (very low carb) diet my HDL more than doubles and my TG dropped by 2/3 and now, I believe my arteries are healing. Here's my story: kzread.info/dash/bejne/naplrayzl67gZbg.html

    Dr Sikaris, I think I have familial hypercholesterolemia. My total is 320mg/dl and my LDL is 242, trigs 61 and hdl 66 mg/dl. I'm 31 years old and I've been on the LCHF diet for about 8 months. I suspect modified LDL because my trigs are over 20mg/dl or 1.1 mmol/l. Do I need to start a statin right now!??! I just told me physcision no........... Please respond and thanks!

My blood works were normal- cholesterol 170, But when Im on keto my cholesterol is 340, ldl 210, triglyceride 67, hdl 70, The good thing is my bp is in normal rate, I sleep good like 8-9hrs. I rather have high cholesterol than not having a good sleep and high bp. Im 62yr old, my hair still black, seldom gray hair which are hiding somewhere lol

    Sorry no. I've heard presentations by numerous medical professionals that refute this guy's claims that statins reduce small dense LDL count. In fact all statins do is cause more receptors on the liver for healthy LDL particles, which actually increases the concentration of small dense LDL in the bloodstream. Statins make the situation worse, not better. And even for those people who take them, studies have shown that taking a statin for multiple years only increases lifespan by a few days on average. Literally less than a week. And that's with cherry-picked data. I'm surprised and a little shocked that this presenter also never mentioned that small dense LDL is actually caused by oxidation of the healthy LDL particles by blood glucose. Hearing a professional promote statins while ignoring high blood sugar as the primary driver of LDL damage is really quite a head-scratcher to me. Perhaps because this video is 7 years old, he wasn't aware of these facts. But bad information like this only confuses people and muddies what is already a very complex topic.

    Too bad your brain shut off when your bias kicked in... He spelled it out VERY clearly that Statins (oh, your brain just shut off again...) Anyway, he spelled out *incredibly* clearly that certain folks have certain genetic abnormalities and *benefit greatly* from these types of LDL lowering pharma drugs by almost completely eliminating their small dense LDL (sdLDL) Without these drugs, these folks have a much higher risk of heart attack and arterial disease.
