Study Shocks Cardiologists: LDL Didn’t Predict Plaque
Metabolic Mind
Reevaluating Heart Disease Risk Factors in the Context of Diet
This chapter explores new research on the ketogenic diet's connection to heart disease, questioning the traditional view of LDL cholesterol as a major risk factor. It highlights the significance of arterial plaque as a more reliable predictor of heart issues and anticipates future studies that may reshape medical guidelines.
What if everything we thought we knew about cholesterol and heart disease risk… doesn’t apply to everyone?
In this episode, world-renowned cardiologist Dr. Matthew Budoff unpacks the results of a landmark one-year study tracking 100 lean, metabolically healthy individuals on a ketogenic diet with extremely elevated LDL levels.
Dr. Budoff is the Program Director, Director of Cardiac CT, and the endowed chair of preventive cardiology at The Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center.
In this interview, Dr. Scher and Dr. Budoff further break down the results of his new publication, which used advanced imaging to demonstrate that LDL cholesterol and ApoB levels are not associated with plaque progression in Lean-Mass Hyper Responders following a ketogenic diet.
📊 Surprising insights:
- Elevated LDL and ApoB did not predict plaque progression
- Some participants with LDLs over 500 showed no plaque at all
- A few participants even experienced plaque regression
- Existing plaque—not LDL-C or ApoB—did predict plaque accumulation in this population
Dr. Budoff explains what these results mean for clinicians, for patients using ketogenic therapy as a medical intervention, and for the broader conversation around cardiovascular disease risk.
“It is important that clinicians, along with the general public, are made aware that personalized, data-driven approaches to assessing risk should be considered based on individual conditions,” said Dr. Budoff. “The existence of this phenotype suggests that alternative markers or tests should be used to establish metabolic health in some cases.”
🎬 These exciting new findings are featured in Dave Feldman and Jen Isenhart’s upcoming documentary, The Cholesterol Code, the story of how a software engineer conducts a groundbreaking study on an unusual group of people—lean, healthy individuals whose doctors are convinced they’ll die young. Real stories of healing with ketogenic diets provide a blueprint for using food as powerful medicine.
