Dave Feldman - 'Interpreting Common Low Carb Lipid Profiles'

Dave Feldman is a senior software engineer, business developer and entrepreneur. He began a Low Carb, High Fat diet in April 2015 and after experiencing a significant rise in his total cholesterol he committed himself to learning everything he could about cholesterol and the lipid system.
As an engineer, Dave spotted a pattern in the lipid system that’s very similar to distributed objects in networks. Through research and N=1 experimentation he has revealed some very powerful data which he continues to share in this presentation and in further detail on his website; www.CholesterolCode.com

[@melissanoelle410]

The thing I love most about keto is that ll of the presentations are backed up by actual information. There’s actual data.

[@alphacause]

The typical doctor, who subscribes to the conventional wisdom, when confronted by the breadth and cogency of the work that Dave Feldman has done, should be embarrassed. Despite not being a medical professional, Dave Feldman, as a software engineer, brings more clarity to the issue of lipidology than most doctors bring to the public concerning that topic. Thank you Mr. Feldman for all the great work you do. You are proof positive that some of the most substantive changes take place when outsiders to a particular issue get involved in the conversation. I would rather listen to you, and another engineer, Ivor Cummins, more than most of the doctors that surround me - men and women who still seem intent on adhering to the same old dogma that they were indoctrinated with decades ago.

[@gabrielyee9458]

completely agree :) But as a medical professional there are SOME of us who know the place of a LCHF minimally processed paleolithic diet. Fat doesn't make one fat; insulin resistance from carbs does :) Convert one doctor at a time :)

[@Jefferdaughter]

What the public does not know is that most of the people we call doctors are merely physicians. This is similar to the difference between an auto technician and and automobile engineer. Or a computer technician and a computer engineer. It is not really the fault of the physicians; they are not taught to think critically, to analyze data or the design and function of the complex and interacting functions of the human body., or question assumptions. Physicians are taught to memorize labels - of anatomical structures, drug names, and also to (hopefully) use a diagnostic tree. Physicians are essentially taught not to think - but what information to regurgitate. During their training and in practice, physicians can be penalized for thinking. few physicians these days work as independent professionals. If they work for an organization, they typically must adhere to 'Standard of Practice', and provide standard care.

[@aquamarine99911]

@@Jefferdaughter More accurate to say that they're taught to minimize the risk of liability or a finding of professional misconduct. High cholesterol => prescribe statins. No ifs, and or buts. No judge or jury would rule against them for doing that. No doctor would testify against them. Ch-ching, cash the cheques and go home. Easy peasy.

Great piece, Dave. Had a heated argument with my GP who was very strident that I should go on a statin. I repeatedly mentioned my HDL/Trig ratio and he told me to "put Triglycerides aside for one moment because the 'bad' cholesterol...." at which point point I lost my rag and told him that his advice was always welcomed but the decision is, ultimately, mine. Sometimes it's just such a struggle to resist being pidgeon-holed. Keep up the great work.

Yeah, I'm a high HDL/lo TG/astronomical LDL guy on a LCHF diet. My cardiologist said, "ratios don't matter, TG doesn't matter. Only total cholesterol matters." Of course he strongly advised statins. When I demurred, he suggested the calcium CT scan. I asked how much radiation is that? He said "oh, about the equivalent of 100 xrays. F that! He doesn't put stock in CIMT, because it only deals with the carotid artery, which is far from the heart. I want to have faith in Dave's approach, but I've also got two kids who need me around for another 8-10 years.

[@patrickh709]

Hey, guess what? Low carb eating is NOT a field where conventional doctors are experts. In fact, they are the most ignorant when it comes to keto and carnivore. They still insist that the SAD diet is the best for you, even though the obesity rate and type 2 diabetes rate in this country has sky rocketed in the past 30 years. I would rather place my trust in an outsider's viewpoint than "conventional wisdom". "Conventional wisdom" was invented and pushed by big food and big pharma companies.

[@Powerman80923]

Dave, I think you hit on something very important at 28:28. "Too much of an energy surplus" is probably a big issue for most people trying to get Triglycerides lower, or keep them low. Excessive energy intake can only increase Triglycerides. Even excessive low GI foods can cause a high GL. Most people I know do not bother to track calories, or don't do it accurately, so by the time they find out they are gaining weight, they have been over consuming consistently for a long time, and they wonder why their healthier diet is not working for their weight or their cholesterol numbers. They also don't have any idea what their maintenance calories are, so calories are likely excessive on average, by default. I've found the on-line BMR calculators to be mostly useless because they are far too generic. Maybe they get you within +/-300 calories per day, but that is not close enough. Plus, the maintenance number is a moving target.

[@bikecontroller3268]

Simple calorie calculation is pounds x 10 = BMR =Basic metabolic requirement [ lying in bed motionless ] BMR x1.3 =for light work, office etc,.BMR x1.4 =moderate exercise. BMR X1.5 =for heavy exercise . etc. Simple enough to remember

So, I guess I'm a hyper responder? After going on the diet and losing 45lbs my cholesterol (ldl mostly) spiked a lot. HDL low and triglycerides low. I'm confused. My dr wanted to put me on meds and I said no way. I'm improving in every other aspect so there's no way I'm stopping now. I feel TONS better. Headache migraine improving (rare now), arthritis (cut my meds by 2/3), fibromyalgia pretty much gone, GERD improved 80%, anxiety lessened 80%, panic attacks pretty much stopped.

What do those studies say about the accepted “normal” or desired cholesterol levels?

[@daven6145]

In 2012, I asked my doctors (yes, I sought a second opinion) about the contradiction between risk factors: first, my very high LDL showed them very high risk; but my .7 ratio of TG/HDL was shown by others to show low risk and to be more important. My question then was which of the two better indicated, or indicated at all my risk of cardiovascular disease? All doctors I spoke with felt it was high LDL and that I'd better go on a statin right away. As far as very low TG and very high HDL I was told that, "the science isn't there yet"--even when I pursued with questions about types of LDL. May I ask a QUESTION? Does anyone know of a mitochondrial disease or metabolic disease specialist, ideally near New Haven, that might take on an older adult as a patient?

Dave, what do you suppose happens to hyper responders if they are on a statin? Do they run in to an energy shortage? I'll bet their basal insulin go up significantly to deal with the gluconeogenesis statins seem to cause "autophagy process" (ie muscle wasting). I wonder this for diabetics that may be on metformin and a statin. It would seem this would be a really bad combination.

OMG, it has zero to do with energy. VLDLs purge fat from liver, that's all.

[@sarahb.6475]

I have read before if you put an athlete on a statin they feel absolutely horrible and they cant do the running or marathons or the stuff they love doing. Because they do so much exercise they need the fuel to not only run but also to do the normal maintenance the body requires from all that activities. The statin stops the repairs and then they get joint pain or other issues. Feel horrible! So most will either quit the statin or quit the exercise. That's just what I had read.

Increasingly it is proposed that many cardiac events occur following the rupture of minor, non-hemodynamically significant atherosclerotic plaque. Indeed many policy makers and some physicians have questioned the importance of traditional screening and treatment strategies for hemodynamically significant coronary artery lesions. As an alternative, it has been suggested that screening and treatment approaches should be guided by emerging data that support the predictive value of measures of inflammation, such as high sensitivity C-reactive protein, or of genetic markers. Our goal is review the biology of acute coronary events and the results of population-based studies and, in this light, consider the usefulness of the current “state-of-the-art” methods for diagnosing coronary heart disease.
