Defining Lean Mass Hyper-Responders

Is high LDL cholesterol always a red flag?

For a growing group of people known as Lean Mass Hyper-Responders (LMHRs), the answer might not be so black and white.

In this video, Dr. Bret Scher unpacks the science and questions behind LMHRs—metabolically healthy, lean individuals who see a dramatic rise in LDL cholesterol after starting a ketogenic diet. Unlike people with familial hypercholesterolemia (FH), their elevated LDL occurs in a unique metabolic context: low insulin, high HDL, low triglycerides, excellent metabolic health, and comes on only after adopting a ketogenic diet.

🔍 In this video, you'll learn:

• What defines a Lean Mass Hyper-Responder

• Why conventional cholesterol risk frameworks may not apply to LMHRs

• The key differences between LMHRs and those with familial hypercholesterolemia

• Why context, like insulin sensitivity and metabolic health, might matter

• Why this phenomenon deserves thoughtful study, not assumptions

This growing curiosity around LMHRs is the focus of a powerful new documentary: The Cholesterol Code. Featuring researchers, clinicians, and individuals living with this phenotype, the film challenges long-held beliefs about cholesterol, risk, and metabolic health, and opens the door to a more nuanced conversation
