Is LDL cholesterol the best way to measure and predict heart disease?

New research suggests no!

Dave Feldman is an engineer turned citizen scientist who has devoted his life to understanding a phenomenon that some individuals around the world are experiencing: a robust increase in LDL cholesterol while on a ketogenic diet.

Dave’s past research has identified a unique phenotype dubbed Lean Mass Hyper-Responders (LMHRs). LMHRs respond to ketogenic therapy with a metabolic profile that includes elevated LDL-C and ApoB levels with otherwise healthy metabolic markers, including low triglycerides, high HDL, low blood pressure, low insulin resistance, and low BMI.

In Dave’s most recent publication, what most doctors would consider dangerously high LDL levels in LMHRs did not correlate with an increased risk of heart disease.

In this video, Dr. Bret Scher sits down with Dave Feldman to discuss this groundbreaking study and its implications for ketogenic therapy and cardiology.

Key Takeaways:

LMHRs on a long-term ketogenic diet who show elevated LDL can show robust metabolic health
LDL-C and ApoB were not linked to plaque progression in LMHRs
Existing plaque did predict future plaque accumulation in LMHRs
Individualized approaches to cardiovascular risk assessment are crucial to serve this group better.

🎬 These exciting new findings are featured in Dave Feldman and Jen Isenhart’s upcoming documentary, The Cholesterol Code, the story of how one engineer’s health experiment sparks a global investigation, exposing myths about cholesterol and reshaping our understanding of heart health. Real stories of healing from disease with ketogenic diets provide a blueprint for using food as powerful medicine.
