The Egg Experiment Begins: 24 Eggs a Day
Norwitz, a researcher and YouTuber, wanted to test an assumption many people hold about eggs: that their high cholesterol content must inevitably raise your cholesterol levels. He made a bold decision to eat 24 eggs a day, amounting to 720 eggs in just 30 days. His goal wasn’t just to consume a massive quantity of eggs but to observe the physiological effects this unusual diet would have on his body, specifically his cholesterol levels.
Eggs are often viewed with skepticism because of their high cholesterol content, which is why they’re frequently avoided by those trying to control their cholesterol levels. But Norwitz set out to challenge this idea by proving whether eating so many eggs would, in fact, lead to an increase in cholesterol. With 720 eggs in just 30 days, he expected his cholesterol levels to rise, but the results were far from predictable.
Understanding Cholesterol: The Science Behind the Experiment

Before diving into the results, it’s important to understand what cholesterol is and why it matters. Cholesterol is a fatty substance that is crucial for building cells, but having too much of it in the blood can lead to heart disease. The Centers for Disease Control and Prevention (CDC) explains that LDL cholesterol, often referred to as “bad” cholesterol, is the type that raises the risk of heart disease and stroke when levels are too high.
High cholesterol has long been linked to a higher risk of cardiovascular diseases, which is why many people aim to reduce their intake of cholesterol-rich foods like eggs. However, in Norwitz’s experiment, the impact of egg consumption on his cholesterol levels defied conventional wisdom.
Hypothesis: Eggs Wouldn’t Affect LDL Cholesterol
At the beginning of his month-long egg-eating challenge, Norwitz hypothesized that eating so many eggs wouldn’t significantly raise his cholesterol levels, especially his LDL cholesterol. He explained that cholesterol, when consumed, binds to receptors in the gut, triggering the release of a hormone called chylomicron. This hormone interacts with receptors in the liver to inhibit the production of cholesterol by the liver itself, maintaining a balance or “homeostasis” in the body. Essentially, Norwitz believed that the body would compensate for the extra cholesterol intake by reducing its own cholesterol production.
This theory, while supported by some research, had never been put to the test in such an extreme scenario—until now.
The Surprising Results: LDL Cholesterol Drops

After completing his egg-eating experiment, Norwitz was astonished by the results. Despite consuming an outrageous amount of cholesterol over the month, his LDL cholesterol actually decreased. In the first two weeks of the experiment, his LDL cholesterol dropped by 2%. And it didn’t stop there. Over the next two weeks, it dropped an additional 18%, bringing his total reduction to a surprising 20%.
This unexpected result shocked many people, as it contradicted the common belief that high-cholesterol foods automatically raise LDL cholesterol levels. Norwitz’s experiment seemed to indicate that the body had a mechanism to regulate cholesterol levels, regardless of dietary intake.
The Science Behind the Drop: How Carbs Played a Role
If you’re wondering how eating a high-cholesterol diet could result in lower cholesterol, Norwitz explains it through biochemistry. He elaborated that when he incorporated more carbohydrates into his diet during the second half of the experiment, it seemed to play a key role in lowering his cholesterol. The added carbs interacted with his gut and liver in such a way that it further suppressed the body’s production of cholesterol.
This phenomenon is explained by the release of the hormone chylomicron, which, when triggered by the intake of cholesterol, signals the liver to reduce cholesterol synthesis. Norwitz further clarified that the extra carbohydrates helped maintain this balance, leading to a decrease in LDL cholesterol levels. He attributed part of the cholesterol reduction to the consumption of fruit, which added fiber and antioxidants to his diet.
Breaking Down the Chemistry: What Happens in Your Body

If you’ve ever studied cholesterol metabolism, you’ll know it’s not just about what you eat but how your body processes that food. Norwitz’s experiment demonstrated that the body has a complex, nuanced system for regulating cholesterol levels. In simple terms, when you eat cholesterol, it binds to receptors in the gut that stimulate the release of chylomicron. This hormone then interacts with the liver, preventing the body from overproducing cholesterol.
By adding more carbs and fruit into his diet, Norwitz essentially ‘tricked’ his body into using these foods to help balance his cholesterol. While this scientific explanation might be complex, the takeaway is simple: the body is capable of self-regulating cholesterol levels, even when we consume large amounts of it.
The Risk of Too Many Eggs: A Warning
Despite the surprising results, it’s essential to recognize that Norwitz’s experiment was not without risks. While the study didn’t show an immediate rise in LDL cholesterol, eating an excessive number of eggs every day for an extended period can still pose risks to your health. Eggs, while nutritious, are also high in calories and saturated fat, which can contribute to weight gain if consumed excessively.
Norwitz’s experiment was extreme, and while the results were interesting, it’s important to approach such diets with caution. The long-term effects of eating a diet so heavily reliant on eggs are still unclear, and there could be other health risks associated with such a high intake of cholesterol, particularly for individuals with pre-existing heart conditions.
The Future of Cholesterol Research
Norwitz’s findings raise important questions about the relationship between dietary cholesterol and blood cholesterol levels. While his experiment demonstrated that the body can adapt to higher cholesterol intake by reducing its own production, more research is needed to fully understand the mechanisms at play. This study could pave the way for future experiments that challenge the traditional understanding of how cholesterol impacts the body.
As we learn more about the intricate systems that regulate our cholesterol levels, we may begin to see changes in dietary recommendations. Perhaps, in the future, eggs will no longer be feared as “cholesterol bombs” but instead embraced for their nutritional benefits.
Should You Try This At Home?
Despite the fascinating results, the answer is clear: don’t try this experiment at home. Norwitz’s body was able to handle the extreme diet due to his young age, health, and unique metabolism. For most people, eating 24 eggs per day would be excessive and could lead to unwanted side effects like weight gain, digestive issues, and nutrient imbalances.
Instead, it’s important to focus on maintaining a balanced diet that includes a variety of whole foods, rich in vitamins, minerals, and healthy fats. If you’re concerned about your cholesterol levels, it’s always best to consult with a healthcare professional before making drastic changes to your diet.
Conclusion
Dr. Nick Norwitz’s egg-eating experiment has provided a surprising glimpse into how the body handles large amounts of cholesterol. While the results were unexpected, they underscore the complexity of human biology and the body’s ability to regulate its internal processes. As we continue to explore the science behind cholesterol metabolism, we can expect more breakthroughs that challenge our preconceived notions about diet and health.
