He ate 700 eggs in a month — what happened next surprised even doctors

A Harvard-trained doctor ate 700 eggs in 30 days to test the effects on his cholesterol — and the surprising results are challenging long-held beliefs about heart health.

In a world filled with diet trends and food fads, it takes something truly extreme to stand out. That’s exactly what Dr. Nick Norwitz, a metabolic health researcher, did when he decided to eat 24 eggs a day for an entire month — a total of 700 eggs — just to see what it would do to his body.

Norwitz, who holds a PhD from Oxford and a medical degree from Harvard, wasn’t doing it for shock value. His goal was to test an old assumption: that eating high-cholesterol foods like eggs automatically leads to dangerous cholesterol levels in the blood — particularly the type known as LDL, often called “bad cholesterol.”

For 30 straight days, Norwitz consumed two cartons of eggs every single day. To put it in perspective, that’s roughly one egg per waking hour. It wasn’t just about pushing his body to the limit — it was about putting long-standing health warnings to the test.

“Most people think eating this much cholesterol would be dangerous,” Norwitz said on his YouTube channel, where he documented the entire challenge. “But I wanted to see what would actually happen, backed by science.”

You might expect that after eating 700 eggs, Norwitz’s cholesterol would skyrocket. But according to his lab results, the opposite happened. Instead of increasing, his LDL cholesterol actually went down — by 2% in the first two weeks, and then a surprising 18% by the end of the month.

So what happened?

Norwitz believes the answer lies in how the body responds to changes in diet. Our livers naturally produce cholesterol, and when we eat more of it, the liver usually makes less. He also noted that when he added healthy carbs — like fruits such as bananas, blueberries, and strawberries — in the final two weeks, his body responded even better.

“The extra dose of carbs dominated over the insane amounts of cholesterol I was consuming,” he explained in an interview with the New York Post.

For decades, people were told that cholesterol-rich foods like eggs were a one-way ticket to heart problems. But recent research has started to shift that thinking. Some experts now believe that the link between dietary cholesterol and blood cholesterol may not be as straightforward as once thought — and that the overall diet pattern matters more.

Still, Norwitz isn’t recommending everyone start bingeing on eggs.

“This is not medical advice,” he warns viewers. “I did this under careful monitoring, and it’s not for everyone.”

His experiment is part of a larger conversation in the health world about how our bodies react differently to food — and why “one-size-fits-all” diets may be outdated.

Dr. Nick Norwitz’s egg experiment may sound extreme, but it’s raising real questions about how we think about food and health. It shows that science is always evolving — and that sometimes, the truth is more complex than old nutrition rules suggest.

So, while 700 eggs might not be your idea of a balanced diet, Norwitz’s story is a reminder to stay curious, question assumptions, and always follow the science.

Would you ever try a challenge like this? Or do you think food experiments should be left to the experts?
