Dave Feldman and I discuss the what causes heart disease, specifically focusing on the consensus view and how it differs from what the science actually shows.

· Cholesterol/lipid oxidation in wall
· Progression through stages of atherosclerosis
· Blockage/rupture of plaque
· Ischemia of blood to heart
· Death/morbidity via MI
Electro-negative LDL
Aggregated LDL
TG-rich Lipoproteins
Risk and factor models
FH mortality—implications for causality
ApoB48

Dave Feldman
Biography:
“I’m a senior software engineer and entrepreneur.
“I began a Low Carb, High Fat diet in April 2015 and have since learned everything I could about it with special emphasis on cholesterol given my lipid numbers spiked substantially after going on the diet. As an engineer, I spotted a pattern in the lipid system that’s very similar to distributed objects in networks.
“I’ve since learned quite a bit on the subject both through research and experimentation which has revealed some very powerful data. With this new general theory, I’ve shifted around my cholesterol substantially without any drugs or special supplements of any kind.
