Rethinking Cholesterol, Keto, and Cardiovascular Risk with Nick Norowitz

Who in the world would try to lower their cholesterol by eating an entire sleeve of Oreos every day for a month? Meet Nick Norwitz, PhD, an Oxford graduate and Harvard medical student who did just that—in an effort to test a hypothesis about cholesterol and metabolic health.

After reversing a serious inflammatory condition with a ketogenic diet, Nick saw his LDL cholesterol spike. Instead of panicking, he turned to research—and self-experimentation—to better understand what those numbers really meant.
In this episode of The Dr. Hyman Show, we explore:

• The health crisis that led Nick to a ketogenic diet

• Why his LDL cholesterol jumped—and what questions it raised

• The Oreo experiment and what it did (and didn’t) reveal

• The nuance around LDL, metabolic health, and cardiovascular risk

• What the science—and Nick’s own experience—suggests about meat, veganism, and finding a diet that works

Check out the episode to hear this fascinating conversation.
