A young fitness enthusiast’s experimental 150-egg diet reveals surprising health benefits, challenges conventional dietary wisdom about cholesterol, and highlights new research on eggs’ role in cardiovascular health.
At a Glance
- Joshua Allard, 25, consumed 150 eggs over five days and reported becoming “very lean” with improved sleep and reduced stress levels
- Recent research shows moderate egg consumption (1-6 eggs weekly) may reduce risk of death from any cause by 17% and cardiovascular death by 29%
- Contrary to past dietary guidelines limiting eggs, studies now indicate no significant negative association between egg consumption and cholesterol levels
- Eggs enhance absorption of important nutrients like vitamin E and contain high-quality protein, B vitamins, folate, and essential minerals
- The protective effects of eggs on cardiovascular health were observed even in individuals with high cholesterol
The 150-Egg Challenge: One Man’s Extreme Diet Experiment
Joshua Allard, a 25-year-old from Oklahoma City, recently completed an unusual dietary challenge: consuming 150 eggs over just five days. The fitness enthusiast documented his egg-only diet on YouTube, providing daily updates on his physical and mental state throughout the experiment. By the end of the challenge, Allard reported significant changes to his physique, becoming “very, very lean” with visible body transformation shown in before-and-after photos. Despite the extreme nature of the diet, he experienced some unexpected benefits beyond physical appearance.
“Well, one, I survived. I did not die. Thank goodness for that. I got very, very lean. I didn’t take any creatine throughout this time. I didn’t really supplement or anything,” Allard explained about his experience. While he noted feeling extremely tired in the evenings, he also reported reduced stress levels and improved sleep quality – unexpected outcomes from such a restrictive regimen. However, nutrition experts caution against such extreme approaches, noting the diet’s significant caloric, protein and fat content.

Debunking Egg Myths: New Research on Cholesterol and Cardiovascular Health
Allard’s extreme experiment comes amid evolving scientific understanding about eggs and health. For decades, U.S. dietary guidelines recommended limiting egg consumption to no more than three per week, based on concerns about dietary cholesterol’s impact on heart disease risk. However, recent research has dramatically shifted this perspective. Multiple studies now indicate that moderate egg consumption is not associated with increased cardiovascular risk and may even offer protective benefits. This represents a significant reversal in nutritional guidance that has influenced American eating habits for generations.
A groundbreaking study published in 2023 found that individuals consuming one to six eggs weekly had a 29% lower risk of cardiovascular death and a 17% lower risk of death from any cause compared to those who rarely ate eggs. Even more surprisingly, these protective effects were observed in people with existing high cholesterol. The research further revealed that combining weekly egg consumption with a moderate- or high-quality diet reduced cardiovascular mortality risk by 33% and 44%, respectively – compelling evidence for including eggs as part of a balanced eating pattern.
The Nutritional Power of Eggs: Beyond Protein
Eggs have earned their reputation as a nutritional powerhouse for good reason. Beyond their high-quality protein content, eggs provide an impressive array of essential nutrients including B vitamins, folate, unsaturated fatty acids, fat-soluble vitamins, choline, and various minerals. Recent research has uncovered additional benefits, including eggs’ ability to enhance the body’s absorption of vital nutrients like vitamin E, which many Americans underconsume. Studies show that adding cooked whole eggs to meals significantly increases both α-tocopherol and γ-tocopherol absorption.
Metabolic marker studies have found positive associations between egg consumption and several indicators of cardiovascular health, including apolipoprotein A1, acetate, mean HDL diameter, and beneficial HDL lipid profiles. Interestingly, research has also revealed a possible “sweet spot” for dietary cholesterol intake – with levels below 250 mg/day (approximately one large egg contains about 186 mg) showing inverse association with mortality risk. These findings support the view that moderate egg consumption may be particularly beneficial for cardiovascular health in the context of an overall balanced diet.
Moderation Matters: Finding the Right Balance
While Allard’s extreme 150-egg challenge demonstrated some short-term benefits, nutrition experts emphasize that moderation remains key when incorporating eggs into a healthy diet. Systematic reviews of clinical trials show no significant negative effects of whole egg consumption on body weight, BMI, waist circumference, or fat-free mass in most adults. However, extended periods of high egg consumption (studies longer than 12 weeks) might increase body weight and BMI, particularly in those with existing health conditions. The scientific consensus points toward moderate consumption – approximately 1-6 eggs weekly – as optimal for health benefits.
For adults over 40 concerned about cardiovascular health, the evolving research on eggs offers reassuring news. Rather than avoiding this nutrient-dense food, moderate egg consumption can be part of a heart-healthy diet. Particularly promising is the finding that combining eggs with high-quality dietary patterns and fiber intake may yield the greatest benefits for cholesterol management and overall health. As with most nutrition recommendations, individual factors like existing health conditions and genetic predispositions should guide personal dietary choices, ideally in consultation with healthcare providers.
