These days, conversations about food often feel louder than ever. From strict elimination plans to viral nutrition trends, fad diets and carefully curated meal plans dominate social media feeds and dinner table debates alike.
People usually make dramatic changes to their eating habits with a clear goal in mind. Some want to lose weight, others aim to gain muscle. Many are searching for improved metabolic health, while others adjust their diet based on ethical beliefs or personal values. At one point or another, most of us have experimented with cutting something out — sugar, carbs, dairy, gluten. But very few have taken on a challenge quite as extreme as Dr. Nick Norwitz.
Dr. Norwitz, a researcher-educator whose mission is to “Make Metabolic Health Mainstream,” recently gained significant attention online after documenting a bold dietary experiment on his YouTube channel. His plan? To consume 700 eggs in a single month and track what happened to his cholesterol levels.
Yes — 700 eggs.
Broken down, that equals roughly two cartons per day for 30 consecutive days. Or, as he described it, about one egg every hour. To reach that total, he ultimately consumed 24 eggs daily — a level of intake that would likely make even devoted breakfast lovers pause.
The motivation behind this extreme food experiment wasn’t shock value alone. Dr. Norwitz wanted to test a specific hypothesis: that consuming a very high amount of dietary cholesterol from eggs would not significantly increase his LDL (low-density lipoprotein) cholesterol, commonly labeled the “bad” cholesterol.
For decades, cholesterol has been viewed with caution. Many people grew up hearing that cholesterol-rich foods — especially eggs — posed a direct threat to heart health. Elevated LDL cholesterol has long been associated with increased cardiovascular risk, and conventional wisdom warned that high dietary cholesterol intake would inevitably raise blood cholesterol levels.
However, nutritional science evolves. In recent years, some researchers have questioned whether dietary cholesterol has as direct an impact on blood cholesterol as once believed. That doesn’t mean 24 eggs a day is advisable — and even Dr. Norwitz’s experiment shouldn’t be interpreted as a universal recommendation — but it does add to an ongoing discussion about how the body regulates cholesterol.
According to updates shared on his YouTube channel, Dr. Norwitz reported that his cholesterol levels did not spike as many might have predicted after consuming 720 eggs in one month. In fact, he claimed the opposite occurred.
During the first two weeks of the experiment, his LDL cholesterol dropped by approximately two percent. Over the following two weeks, he reported an even more pronounced decline — about 18 percent in total.
To explain these findings, Dr. Norwitz discussed how the liver plays a key role in regulating cholesterol production. The body doesn’t simply absorb dietary cholesterol in a linear way; instead, internal synthesis adjusts in response to intake. He also noted that later in the experiment, he increased his carbohydrate consumption.
As reported by the New York Post, Dr. Norwitz explained:
“The extra dose of carbs dominated over the insane amounts of cholesterol I was consuming.”
In the final phase of his experiment, he incorporated fruits such as blueberries, bananas, and strawberries into his daily meals. Following this adjustment, he observed the most significant reduction in LDL cholesterol levels.
While the results are intriguing, they also highlight how complex human metabolism can be. Individual responses to dietary cholesterol vary, and factors such as genetics, overall diet composition, physical activity, and metabolic health all play important roles. One person’s outcome under controlled conditions does not automatically translate to universal dietary advice.
The broader takeaway from Dr. Norwitz’s egg experiment may not be that cholesterol concerns are unfounded, nor that extreme eating patterns are harmless. Rather, it underscores that nutrition science continues to develop — and that the relationship between dietary intake and blood biomarkers is more nuanced than once assumed.
Whether viewed as a bold metabolic health experiment or simply an unconventional food challenge, the 700-egg month certainly sparked conversation.
