N of 1 Trial: Harvard Med Student Eats 720 Eggs in 30 Days, Highlighting a Trend in N=1 Science
Harvard medical student Nick Norwitz, who holds a doctorate in physiology from Oxford, recently embarked on a personal health experiment that captured public attention. In just one month, he ate 720 eggs—an average of 24 per day—and observed an 18 percent drop in his LDL cholesterol levels, commonly called “bad cholesterol.” He wasn’t advocating an extreme egg diet, which would not be a wise long-term way to eat. Nor was the science behind this experiment revolutionary—research has already shown that dietary cholesterol doesn’t significantly impact blood cholesterol for most people. Still, the story went viral. Many interpreted it as a green light to enjoy more eggs. However, the full takeaway of the experiment went beyond diet. Norwitz’s experiment highlights a growing trend in the scientific community, where individuals and researchers alike are turning to personalized, real-world experiments, often called N=1 studies, to answer pressing health questions. Eating two dozen eggs a day ...
