1:36 Spencer’s background
3:35 The big seven questions intro and context into Spencer and Dave’s background together
4:52 Question Number One: What is your current opinion on the optimal range of Total Cholesterol?
5:24 Question Number Two: What is your current opinion on the optimal range of LDL Cholesterol?
5:55 Question Number Three: What is your current opinion on the optimal range of HDL Cholesterol?
6:43 Question Number Four: What is your current opinion on the optimal range of Triglycerides?
7:00 Question Number Five: In regards to cholesterol lowering medication, do you think too little or too much is being prescribed?
7:33 Question Number Six: If you had to guess a percentage, how much of modern heart disease is a result of diet?
8:10 Question Number Seven: Do you feel those on a low carb diet should take steps to lower LDL-C if it has increased, if all other cardiovascular risk factors have improved?
9:20 How Spencer’s opinion on cholesterol has developed, and how it has changed over the years
12:42 How Spencer sees LDL’s role in atherosclerosis
14:20 Coming from a position of skepticism towards the LDL hypothesis and why Spencer’s views changed
15:45 Study mentioned: ENHANCE trial
Link: nejm.org/doi/full/10.1056/NEJMoa0800742
16:35 Study mentioned: IMPROVE-IT trial
Link: ncbi.nlm.nih.gov/pubmed/29263150?dopt=Abstract
16:50 Note: Genomic Wide Association studies refers to studies which look at genetic causes of something (e.g. high or low cholesterol) and associate it with occurrence of cardiovascular disease or other issues.
18:05 Do you feel there are positive things about having higher LDL cholesterol or higher LDL particle count?
21:30 Looking at All-Cause Mortality in people with hypobetalipoproteinemia or abetalipoproteinemia
Note: Hypobetalipoproteinemia is a condition resulting in unusually low levels of apoB containing lipoproteins (VLDL, LDL, chylomicrons, etc), abetalipoproteinemia is a similar condition resulting in near absent levels of apoB containing lipoproteins.
23:40: Social Media Questions intro
23:55 What is “Best practice” for evaluating desirability of statin therapy and weighing likely benefit versus potential adverse side effect?
26:00 The importance of having honest dialogue with your doctor (and others)
28:00 Is the focus in the right place for areas of interest and understanding for doctors (diet, and medicine)?
30:48 What is the current verdict on triglyceride to HDL ratios, and how do you correct a high ratio?
32:40 Question intro: Please include the ramifications of apoe4 in these discussions
33:00 Discussion on lean mass hyper-responders
35:40 Hyper-responders in Spencer’s clinic, and in Dave’s experience, and apoe4
38:00 Dysbetalipoproteinemia and apoe2/2 isoform
Note: Dysbetalipoproteinemia is a genetic disorder marked by increased levels of remnant lipoproteins due to impaired clearance.
39:00 Dave’s white bread and processed meat experiment and impact of energy metabolism on lipids
39:40 For hyper-responders, why does switching saturated fat for other fats lower LDL-P and is this beneficial?
42:15 What explains the rise in CVD in the industrial/developing nations and why do undeveloped people not have cardiovascular disease?
44:25 What is the importance of very high LDL-P in light of having pattern A in regard to cardiovascular disease?
Note: Pattern A is referring to having a majority of LDL particles that are a larger size, compared to having a predominance of “small dense” particles, classified as Pattern B. Pattern B is considered to impart higher risk of cardiovascular disease.
46:40 Genetically high levels of LDL versus dietary causes, are they the same? Will Lean Mass Hyper-responders develop issues like xanthomas?
51:50 How important/significant is RBC [red blood cell] cholesterol pool to our health, and how is it impacted by changes in the lipoprotein cholesterol pool?
53:15 Blog questions intro
53:35 What is the role of cholesterol on lipoproteins, if the energy model is correct?
55:00 Dave’s resistance training experiment
58:45 What does Spencer think about the study regarding all-cause mortality being inversely related to total cholesterol in women?
59:40 PCSK9 inhibitors, what to make of the data?
1:02:04 Quality of life consideration
1:04:10 Questions from the chat
1:04:35 How do they measure cholesterol if it’s water insoluble?
1:06:40 What does Spencer think about CAC scores?
Note: A Coronary Artery Calcium score is a CT scan that looks for calcified plaque in the arteries. The scores range from 0 to more than 1000 with 0 being very low risk, and more than1000 being extremely high risk (of cardiovascular disease risk, as well as all-cause mortality).
