Harvard Researcher’s 24-Eggs-a-Day Test Shows LDL Drop, Reigniting Egg–Cholesterol Debate

Clinicians call the self-test anecdotal evidence that does not change current dietary advice.

Overview

  • Nick Norwitz, a Harvard metabolism researcher, says 30 days of eating 24 eggs a day ended with an about 18% drop in his LDL cholesterol.
  • He added fruit in the final two weeks and suggests those carbohydrates, not the eggs, drove the larger decline.
  • The finding comes from a one-person, uncontrolled trial and has not been peer reviewed or replicated.
  • Independent experts warn against copying the regimen and note that cholesterol responses differ widely between people.
  • Germany’s nutrition society still advises about three eggs a week, though some doctors and a 2018 BMJ cohort study report little harm from higher intake in healthy people.
