Man Who Ate 900 Eggs in a Month Reveals the Shocking Impact on His Strength, Testosterone and Libido

Could eating 30 eggs a day lead to rapid muscle growth and increased testosterone? One fitness youtuber put this theory to the test, consuming 900 eggs in 30 days after reading about a 1960s bodybuilder who claimed that eating 36 eggs daily could produce effects similar to a mild steroid cycle.

The goal? To track changes in strength, body composition, and health markers like cholesterol and testosterone. Before starting, he documented his weight, strength levels, and bloodwork for comparison.

But was this extreme diet worth it? Could eggs alone enhance muscle growth beyond a standard high-protein diet? The journey came with unexpected digestive struggles, sleep changes, and surprising blood test results—both good and bad.

Setting the Stage: Preparations and Baseline Testing

To measure the impact of the experiment, baseline tests were taken before the first egg was cracked. These included:

• Body weight and composition to track muscle and fat changes.
• Strength tests for the three major lifts: squat, bench press, and deadlift.
• Bloodwork measuring cholesterol, testosterone, and other key markers.

In addition to diet, he committed to serious lifting for the month, focusing on heavy compound movements to maximize potential muscle gains.

The Diet Plan: What 30 Eggs a Day Looks Like

The original 1960s plan recommended consuming the eggs as a smoothie with half-and-half, banana, and protein powder. It also included a pound of hamburger meat for lunch and up to two pounds of steak with vegetables for dinner.

For this experiment, the diet was slightly different:

• 30 eggs per day (mostly raw yolks, some cooked whites).
• Rice, beef, yogurt, fruit, honey, and protein bars for additional calories.
• Total calorie intake: ~3,300 to 3,700 per day.

One reason for consuming raw egg yolks was to avoid oxidizing the fats through cooking. However, this choice would later prove problematic.

Early Days: Adjusting to the Diet

The first few days were relatively easy. Despite the high number of eggs, the total calorie intake wasn’t excessive, especially for someone engaged in daily strength training.

One unexpected discovery was that whole eggs appeared to be more effective for muscle growth than egg whites alone. Research supports this—one study found that eating whole eggs post-workout stimulated more muscle protein synthesis than consuming the same amount of protein from egg whites alone.

But soon, the real challenges began.

Digestive Struggles and Adjustments

By day five, severe gas and bloating became a major issue—bad enough to be banished to the couch for the night. The likely culprit? Mangoes.

Mangoes are high in fermentable short-chain carbohydrates, which can disrupt digestion and cause bloating. After cutting them out, digestion improved. But this wouldn’t be the last dietary challenge.

Strength Gains and Mental Effects

By day nine, the benefits started to appear:

• Increased focus and energy levels.
• Higher libido.
• More motivation and drive in daily tasks.

“I usually procrastinate on my writing, but within the first 10 days of this egg diet, I had written eight different posts on my Substack,” he noted.

Could eggs actually increase testosterone?

The Role of Cholesterol, Fats, and Nutrients in Testosterone

Each day, 30 eggs provided:

• 190g protein
• 2100% of the daily cholesterol intake
• 45g saturated fat
• 150% of daily vitamin A
• 120% of daily vitamin D
• Tons of B vitamins, choline, and minerals

Some studies suggest that higher dietary cholesterol and saturated fat intake may boost testosterone levels. One review even proposed that increased cholesterol consumption on a ketogenic diet might contribute to testosterone production.

Vitamin A also plays a role. A study on puberty induction in boys found that supplementing vitamin A and iron was just as effective as supplementing testosterone itself. However, it’s unclear if excessive vitamin A intake directly increases testosterone in adults.

Did 30 Eggs a Day Boost Libido?

One of the most noticeable effects of the egg-heavy diet was a significant increase in libido. By the second week, he reported feeling more driven, assertive, and sexually energized—a shift that coincided with higher overall energy levels and focus.

The link between diet and sex drive is well-documented. Cholesterol is a precursor to testosterone, and with 30 eggs providing 2100% of the daily cholesterol intake, it’s possible that this played a role. Additionally, eggs are rich in saturated fat, vitamin A, and vitamin D, all of which are associated with hormonal balance and reproductive health.

Studies suggest that low-fat diets can lead to reduced testosterone levels, and one review found that men who consumed higher amounts of saturated and monounsaturated fats had higher testosterone concentrations. Since testosterone is closely linked to libido, an increase in dietary fats could explain the heightened sex drive.

Interestingly, despite the subjective feeling of higher testosterone, bloodwork showed no significant change in testosterone levels. This raises the question: Can dietary factors enhance libido without directly increasing testosterone? Some research suggests that neurological and dopamine-related mechanisms may also be at play, meaning nutrients like cholesterol and vitamin A could still boost sex drive through pathways beyond hormone levels alone.

While the experiment didn’t result in a measurable testosterone spike, the increase in energy, motivation, and libido was undeniable. Whether due to better nutrition, improved training, or the placebo effect, one thing was clear—30 eggs a day didn’t hurt in that department.

A Major Setback: Severe Stomach Issues on Day 20

By the third week, severe stomach cramps, constipation, and nausea set in. After an hour stuck in the bathroom and vomiting, it was clear that something was wrong.

The likely culprit? Raw egg whites.

Egg whites contain trypsin inhibitors, which can interfere with protein digestion and cause inflammation. After switching to fully cooking all egg whites, digestion improved, and the experiment continued.

But now, another issue emerged—eating 30 cooked egg whites was much harder than drinking them raw.

The Final Stretch: Less Sleep, More Energy

By the last 10 days, an unexpected side effect appeared: reduced sleep but higher energy levels.

“I don’t drink caffeine, but I was waking up an hour early some days, too excited to start the day,” he said.

This could be related to higher vitamin A and D intake, both of which play roles in hormone regulation.

The Final Results: Muscle Gains and Health Markers

Body Composition and Strength Gains

• Gained 6 kg (13 lbs)—a mix of muscle, water, and some fat.
• Legs grew noticeably thicker.
• Significant strength gains across all lifts:

Lift	Start Weight	End Weight	Gain
Deadlift	120kg (265lbs)	140kg (309lbs)	+20kg (44lbs)
Bench Press	100kg (220lbs)	110kg (242lbs)	+10kg (22lbs)
Squat	95kg (206lbs)	115kg (254lbs)	+20kg (44lbs)

Blood Test Results

Despite consuming massive amounts of cholesterol, the impact on blood lipids was surprising:

• LDL (“bad” cholesterol): Stayed nearly the same (102 → 108).
• HDL (“good” cholesterol): Increased (37 → 45).
• Triglycerides: Dropped significantly (87 → 39).
• Testosterone: No measurable increase, despite feeling more energetic and driven.

Final Thoughts: Was It Worth It?

While the strength and muscle gains were impressive, they weren’t quite steroid-like. However, the experiment proved that eggs are an effective food for bulking—especially when combined with heavy lifting.

If repeated, one key change would be replacing egg whites with red meat for easier digestion.

Ultimately, this extreme diet reinforced what many lifters already know: high-quality protein, dietary fats, and consistency in training matter more than any single “magic food.”

Would he do it again? Maybe—but next time, without the raw egg whites.
