Conversations about food today are louder than ever. Fad diets, viral nutrition trends, and carefully curated meal plans dominate social media and dinner table debates alike. People make dietary changes to lose weight, gain muscle, improve metabolic health, or align with personal values.
Few challenges are as extreme as Dr. Nick Norwitz’s recent experiment. A researcher-educator focused on metabolic health, he documented consuming 700 eggs in a single month on his YouTube channel to see how it would affect his cholesterol.
That meant roughly 24 eggs per day—about one every hour. The goal was to test whether a massive intake of dietary cholesterol would significantly raise LDL, or “bad” cholesterol.
For decades, conventional wisdom warned that cholesterol-rich foods like eggs increased cardiovascular risk. But recent research has questioned whether dietary cholesterol directly raises blood cholesterol, suggesting that the body may adjust internal production in response to intake.
According to Dr. Norwitz, his LDL cholesterol did not spike. During the first two weeks, it dropped about 2 percent, and by the end of the month, it had declined roughly 18 percent.
He explained that the liver regulates cholesterol synthesis, meaning dietary cholesterol does not simply translate into higher blood levels. Later in the experiment, he also increased carbohydrate intake and added fruits like blueberries, bananas, and strawberries, which coincided with the most significant LDL reductions.
The findings illustrate the complexity of human metabolism. Genetics, overall diet, activity levels, and metabolic health all influence individual responses. One person’s results under controlled conditions cannot be generalized as universal advice.
Dr. Norwitz’s 700-egg month is less about promoting extreme eating and more about exploring how nutrition science evolves. It highlights that the relationship between what we eat and our blood markers is nuanced, sparking discussion about cholesterol, diet, and metabolic health in ways few other experiments could.
