Guest Bio

Dave Feldman

Dave Feldman is a software engineer and runs the Cholesterol Code website. In 2015 Dave adopted a low-carb high-fat diet, which improved his overall health. However, upon seeing his LDL-cholesterol skyrocket, he set out learn all he could about blood lipids and health.

Dave has gained prominence as a “LDL-skeptic” and promoter of his “lipid triad” hypothesis. This lipid triad relates to a situation where one sees high LDL-C, high HDL-C and low triglycerides. Dave hypothesises that in such a context, the high LDL-C does not confer high risk of cardiovascular disease. This is counter to the current consensus position of the lipid hypothesis, where LDL plays a causal role in atherosclerosis development.
