Man Ate Over 700 Eggs In One Month To See What It Would Happen To His Body

In 2024, a Harvard medical student named Nick Norwitz decided to run an extreme self-experiment: eat 720 eggs over one month — that’s 24 eggs per day — and track what happens to his cholesterol, metabolism, and overall health.

His stated goal: spark conversation about metabolism, dietary cholesterol, and how our bodies adapt — not necessarily to recommend this diet to others.

While such an extreme challenge is not a health recommendation, it provides a provocative case study for exploring deeper questions:

  • How does very high dietary cholesterol affect blood lipids?
  • What does this tell us about “good” vs “bad” cholesterol, metabolic flexibility, and individual variability?
  • From a holistic health perspective, how might one navigate dietary extremes, body responses, and risk mitigation?

Let’s dive in.

What He Did & What He Measured

Diet Protocol & Context

  • He consumed 24 eggs daily, prepared in many forms (scrambled, boiled, fried, omelets)
  • Over the first two weeks, he maintained an otherwise low-carbohydrate diet; then in the final two weeks, he reintroduced some carbs (e.g. fruit) to observe shifts.
  • His total dietary cholesterol intake over the month reportedly reached ~ 133,200 mg.

He tracked lipid panels (LDL, HDL, total cholesterol) and metabolic markers to see how his body responded to this enormous cholesterol load.

The Results: Lipids & Surprises

Contrary to many expectations, his LDL (“bad cholesterol”) dropped by nearly 20% over the course of the experiment.

  • During the first week, LDL fell ~2%.
  • In the final two weeks (with added carbs), LDL dropped more drastically (~18%).
  • His prior “baseline” LDL was reported around 90 mg/dL under his usual mixed diet.

He attributed part of the decline to the metabolic shift when he added carbs back in — suggesting that his body’s cholesterol synthesis and regulation responded to changes in substrate availability.

He described the experiment as “provocative” and aimed to push conversations around metabolic health rather than endorse such extreme behavior.

Interpreting the Results: What They Might — and Might Not — Tell Us

Why LDL Might Fall in This Context

This counterintuitive result (eating 720 eggs yet seeing LDL decline) raises questions about human metabolic flexibility and cholesterol regulation:

  1. Endogenous suppression
    The body produces cholesterol internally (in the liver) when dietary intake is low. Consuming large amounts of dietary cholesterol may downregulate internal cholesterol synthesis, leading to net decreases in production.
  2. Gut-liver feedback loops
    Dietary cholesterol may influence gut receptors and signaling molecules (e.g. hormones influencing hepatic cholesterol uptake or synthesis). Some theories suggest receptor-mediated feedback (e.g. signals like “choleson”) that modulate hepatic cholesterol output.
  3. Metabolic phenotype & individual variation
    Norwitz’s metabolic health, insulin sensitivity, and baseline lipid handling may have positioned him to respond favorably. Not everyone would experience the same effects.
  4. Influence of reintroduced carbs
    The addition of carbohydrates in the latter half might have shifted metabolism (e.g. moving out of ketosis, altering lipid flux) in a way that more strongly suppressed LDL.

Why We Must Be Cautious: Limits & Risks

  • This is n = 1 — a single case, not a controlled clinical trial.
  • He was probably metabolically healthy before the experiment; results may not generalize to those with dyslipidemia, metabolic syndrome, or genetic cholesterol disorders.
  • Extreme overload may carry hidden risks: oxidative stress, inflammation, changes in lipoprotein particle size or function, arterial endothelial effects, etc.
  • We don’t know long-term outcomes (vascular disease, atherosclerosis, arterial calcification).
  • The effect may be transient — sustained intake may behave differently.
  • There may be reporting or selection biases: he chose to do this experiment and was motivated to present results in a certain light.

What Science & Literature Say About Eggs, Cholesterol & Health

To place this experiment into broader context, here’s what the literature generally shows about eggs, dietary cholesterol, and cardiovascular/metabolic risk:

  • A 2023 review (“Eggs: Healthy or Risky? A Review of Evidence from High Dietary Intake”) described that eggs — in randomized, controlled trials — can increase total cholesterol, LDL, and HDL versus no-egg diets, but effects are often modest and vary by individual.
  • Observational studies generally support that moderate egg consumption (e.g. ≤ 1 egg/day) is not strongly linked to increased cardiovascular disease risk in healthy individuals.
  • In some studies, higher egg intake is even associated with lower all-cause mortality or no detrimental outcomes — though confounding (health behaviors, diet quality) is a concern.
  • The interplay between dietary cholesterol and saturated fat, overall dietary pattern, metabolic health, and genetic factors strongly modifies outcomes.

Thus, the mainstream consensus remains: moderate egg consumption is generally safe for many, but consuming hundreds of eggs per month is far outside standard guidelines and carries unknown risk.

Holistic Health Perspectives: What We Can Learn

Even though the egg experiment is extreme and not advisable, it offers several insights and lessons that align with holistic health thinking:

1. Respect individual variability & adaptability

Our bodies differ vastly in how they process cholesterol, fats, and macronutrients. What “works” for one person might backfire for another. Experiments (with care) can help map your own metabolic responses — but always with caution.

2. Always monitor biomarkers, not just symptoms

If someone were to try a high-cholesterol diet, they should frequently monitor lipid panels (LDL, HDL, triglycerides), lipoprotein particle size (if available), inflammation markers (CRP, oxidized LDL), and vascular health over time.

3. Focus on holistic balance, not extremes

Extreme challenges can be educational, but day-to-day health is built on balance, sustainability, and system resilience (nutrition, movement, sleep, stress). Rare stunts don’t replace foundational health.

4. Be cautious of hype or overselling

It’s easy for extreme experiments to be taken out of context. A single favorable outcome doesn’t justify sweeping claims. Responsible nuance and humility matter.

5. Use experimentation consciously

If one experiments with diet (e.g. high-cholesterol phases, fasting, high-fat diets), do so under supervision, with baseline testing, and exit strategies. Always have health goals, not just curiosity.

Practical Takeaways & Warnings

  • Don’t replicate the experiment without medical oversight. This was designed for exploration, not guidance.
  • If exploring dietary extremes, start with low-risk modifications: moderate egg intake, adjust saturated fat, monitor response.
  • Pay attention to symptoms of vascular health decline: chest discomfort, fatigue, peripheral circulation changes.
  • Invest in nutrient diversity: eggs are nutrient-dense but don’t provide all essential nutrients. Variety is key.
  • Support antioxidant, anti-inflammatory, vascular resilience systems: fiber, phytonutrients, healthy fats, exercise, sleep.
  • Share results (to trusted practitioners) if experimenting, and don’t hide red flags or declines.

Conclusion: Provocative, Not Prescriptive

The story of a man eating over 700 eggs in a month and seeing a surprising drop in LDL invites us to question assumptions — but it shouldn’t dictate behavior. It is a provocative metabolic experiment, not proof of safety or recommendation.

In holistic health, the value lies in listening to your body, testing carefully, staying grounded in broader principles, and honoring individual variation. Extreme stunts may teach, but sustainable health is built on balance, feedback, and consistency.
