If you think you’ve seen it all when it comes to extreme diet experiments, fitness creator Joseph Everett just raised the bar — or the carton.
The Tokyo-based YouTuber behind the popular channel What I’ve Learned decided to spend an entire month eating 30 eggs a day — that’s 900 eggs in 30 days — all to test an old bodybuilding claim that eating three dozen eggs a day could build muscle as effectively as a mild cycle of steroids.
“The science on this is really limited, so instead of trying to dig up all these papers on eggs, I figured I’d just go ahead and eat 30 a day for a month and see what happens,” Everett said in his video, which has already racked up more than 950,000 views.
30 Eggs A Day — Every Day
Everett’s daily diet was built around eggs in every imaginable form — omelets, smoothies, and even raw yolks — but he also added a few extras to help him get through the intense plan.
“A typical day of eating for me would usually be something like 30 eggs, a bowl of rice, a bit of beef, a bit of yogurt, some fruit, a bit of honey and maybe a protein bar,” he explained.
Altogether, his meal plan came to 3,300–3,700 calories per day, far above the standard recommendation for most men.
To measure the impact, Everett tracked his weight, gym performance, and bloodwork, testing everything from testosterone and cholesterol levels to triglycerides (a dangerous fat linked to heart disease).
At the start, he weighed 78kg (171 lbs) and described himself as a casual gym-goer rather than a “serious lifter.”
The First Week: More Focus, More Energy — And A Lot Of Gas
It didn’t take long for Everett to notice changes.
“By day nine, I was feeling pretty great,” he said. “I had more focus, tons of energy, my libido was higher, and I was a bit more driven and unrestrained.”
He even speculated that the high-fat, high-cholesterol diet could be fueling a testosterone boost.
However, not everything about the egg-heavy experiment went smoothly.
“On night five, I had so much gas I couldn’t sleep,” Everett admitted. “My girlfriend asked me to sleep on the sofa because the flatulence was keeping her awake.”
Despite the bumpy start, he said the diet was “relatively easy” to maintain — until week three, when things went south.
Day 20: Digestive Disaster
By the third week, Everett’s body had had enough.
“I found myself stuck in the bathroom for over an hour, really constipated and cramping up,” he recalled. “Standing up made the cramps even worse, but I had to get up because I also needed to puke.”
The culprit turned out to be trypsin inhibitors — compounds found in raw egg whites that can interfere with digestion and protein absorption.
He had switched to drinking all 30 eggs raw to save time, but once he started cooking the whites again, his stomach issues disappeared. “The food sat on my stomach better, I felt lighter, less bloated and my performance on the toilet was great,” he joked.
The results: More Muscle, Better Lifts, And Surprising Bloodwork
By the end of the month, Everett’s transformation was impressive. He gained 13 pounds (6 kg) of muscle, bringing his total weight up to around 84 kg (185 lbs).
His gym numbers jumped too — adding 20 kg (44 lbs) to his deadlift and 10 kg (22 lbs) to his bench press.
And despite his initial fears, his blood tests told a surprisingly positive story:
- Bad cholesterol (LDL) only rose by six points.
- Good cholesterol (HDL) increased significantly.
- Triglycerides, a harmful blood fat, actually dropped.
“My mood, focus, libido and energy all made it seem like I had higher testosterone but apparently not,” he said after reviewing his final lab results, which showed no change in testosterone levels.
After consuming 900 eggs in 30 days, Everett said the experiment left him with a new respect for just how adaptable the human body can be.
He described the experience as “quite easy overall” — apart from the occasional digestive chaos — and even hinted that he’d consider repeating it.
“I might do this again if I needed to bulk up,” he said. “But next time, I’d probably swap the egg whites for red meat.”
Cracking The Myth
Everett’s month-long challenge was inspired by bodybuilding legend Vince Gironda, who once claimed that eating 36 eggs a day could replicate the effects of an anabolic steroid injection.
While Everett’s results didn’t quite confirm that myth, they did show that a high-protein, high-cholesterol diet — even one built around eggs — can produce noticeable gains in muscle mass and strength, without catastrophic side effects.
Still, the YouTuber’s experiment goes far beyond what nutritionists would recommend. The American Heart Association advises healthy adults to eat no more than one to two eggs per day, stressing balance and variety in protein sources.
The Conclusion?
After 900 eggs, one near-bathroom breakdown, and an impressive 13-pound muscle gain, Joseph Everett’s viral challenge has certainly scrambled a few expectations.
The fitness creator’s conclusion? If you can stomach 30 eggs a day, you might just gain some muscle — but you’ll definitely gain some stories.
