Exercise Scientist Breaks Down Exactly Why Liver King’s “Ancestral” Fitness Claims Are Scientifically Nonsense

Brian Johnson, better known by his internet alias Liver King, built an empire on a simple pitch: embrace the ancestral way of living, eat raw organs, reject modern comforts, and you too can look like a ripped caveman. But when a leaked email revealed his $10,000-per-month anabolic steroid habit, the primal illusion came crashing down.

Now, Dr. Mike Israetel, a PhD in Sport Physiology, co-founder of RP Strength, and a longtime educator in exercise science, has delivered a scathing video takedown of the Liver King’s brand — mocking his pseudoscientific claims, his marketing tactics, and his continued dishonesty in the aftermath of being exposed.

“He’s a borderline sociopath,” Dr. Mike says bluntly in the video. “People like this have no problem lying — and when they get caught, they just apologize and keep lying. It’s like a cheat code in a video game. Infinite ammo.”

Liver King’s Public Apology Didn’t End the Lies

After being outed in late 2022 for secretly using steroids while preaching a “natural ancestral lifestyle,” Johnson issued a tearful apology on social media.

But as Dr. Mike points out, nothing really changed.

“He still looks the same. Same vascularity. Same trend tan. Those aren’t the signs of someone who came off the sauce,” he says. “Those vials he threw away? They’re just the empty ones. He’s still on the stuff — 100%.”

According to Dr. Mike, the apology was little more than damage control, designed to retain his customer base and keep the supplement business afloat. The branding continues, the bizarre diet videos keep coming, and Johnson’s body still looks chemically enhanced.

“It’s a scam, and it’s built on deception. He’s got no shame because deception is the business model.”

Pseudoscience Disguised as ‘Primal Wisdom’

A central feature of Liver King’s empire is his so-called “Nine Ancestral Tenets” — a set of lifestyle principles that he claims are rooted in evolutionary biology. Dr. Mike takes a microscope to each one, exposing them as either vague, redundant, or outright nonsensical.

“Move,” for example, encourages people to walk, carry heavy things, and stay active.

“That’s not Primal — that’s just exercise,” Dr. Mike says. “You don’t need to be barefoot in a loincloth to do resistance training.”

Johnson demonstrates workouts like carrying kettlebells for miles or loading backpacks with hundreds of pounds of weights, framing it as an “ancestral” method of fitness. But according to Dr. Mike, it’s just inefficient nonsense.

“You can get in much better shape, in way less time, doing basic compound lifts. Barbells. Dumbbells. Machines. This is just cosplay fitness.”

Even more absurd, he notes, is the “Shield” tenet — which involves turning off Wi-Fi at night, avoiding polyester clothing, and rejecting modern soaps due to so-called “hormonal disruptions.”

“Wi-Fi isn’t bad for you,” Dr. Mike explains. “There’s no real evidence to back that up. Companies that build this tech have huge incentives to prove its safety — way more due diligence than anything Liver King sells.”

He calls Johnson’s rhetoric “tin foil hat bullshit” and suggests that most of it is designed to stoke fear and encourage product purchases.

Dangerous Diet Dogma

One of the most disturbing parts of Liver King’s brand is his raw organ meat diet — frequently showcased in videos where he eats raw liver, bone marrow, animal testicles, and even fertilized duck embryos straight from a wooden slab.

“Please don’t eat that off the table with your dirty fingers,” Dr. Mike pleads sarcastically. “I don’t even think he uses soap, because apparently that messes with your hormones too.”

Liver King promotes a “nose-to-tail” approach, claiming it honors the full animal and delivers optimal nutrients.

Dr. Mike isn’t buying it.

“This is peak white people nonsense,” he says. “When you’ve run out of actual problems, you invent problems like not eating enough spleen.”

He also highlights the contradiction between rejecting “processed food” while injecting pharmaceutical-grade hormones.

“You don’t get more processed than a vial of growth hormone. Let’s not pretend this is natural.”

Toxic Masculinity Disguised as Health Advice

Beyond diet and fitness, Liver King’s brand leans heavily on hyper-masculine performance — urging men to “uncage their inner barbarian,” embrace discomfort, and sacrifice convenience for raw strength and grit.

But Dr. Mike suggests that this narrative is manipulative marketing, not genuine advice.

“You don’t need to freeze your balls off in a lake to be healthy,” he says. “Train hard. Eat decently. Sleep well. Love your people. That’s the recipe — not hypothermia and duck fetus.”

In one scene, Johnson and his wife plunge into an icy lake, claiming it builds connection and cognitive health. Dr. Mike is unmoved.

“She looks miserable. That’s not a date. That’s a TikTok thirst trap disguised as ancestral bonding.”

He also criticizes the constant use of buzzwords like “neurocognitive health” — a favorite in the alt-wellness world — which sound impressive but often lack substance or measurable value.

“It’s just a salad of smart-sounding words. It convinces people to buy crap they don’t need.”

The Business Behind the Beard

Johnson’s supplement line — which includes liver bars, organ pills, and “primal fuel” powders — is the real moneymaker.

Dr. Mike reminds viewers that the entire spectacle — the beard, the shirtless ranch life, the workouts, the rituals — is a commercial campaign, not a lifestyle rooted in reality.

“He lives on a multi-million dollar ranch in Texas, not in some mud hut. Every video is choreographed, captioned, shot with professional lighting. It’s not primal — it’s marketing.”

Worse, it targets young, insecure men who feel lost in modern life and are seeking direction. Liver King offers an identity, a tribe, and a solution — for a price.

“It’s cult-like,” Dr. Mike says. “He’s weaponizing aesthetic appeal and insecurity to sell snake oil. Classic grifter playbook.”

What True Health Actually Looks Like

In stark contrast, Dr. Mike offers simple, evidence-based advice for those trying to improve their health:

  • Train regularly with basic strength movements.
  • Eat whole foods the majority of the time, without obsession.
  • Sleep enough to feel rested and recovered.
  • Maintain relationships that are supportive and positive.
  • Relax — your health doesn’t require suffering or liver shots.

“You’re already 99.9% of the way there if you do those things,” he says. “You don’t need to smear bone marrow on your beard or take your shirt off in a river.”

He also encourages critical thinking, especially when evaluating health claims online.

“Just because someone looks good doesn’t mean their advice is good. Don’t be a mark. Don’t fall for charisma over credibility.”

A Final Verdict on the Liver King

In Dr. Mike’s words: “Liver King is not a real person. He’s a character — a liar with a six-pack, built on trend and testosterone, selling you fake answers to real problems.”

He wraps the video with a brutally simple rating:
“I rate Liver King a scumbag cocksucker out of 10.”

Harsh words — but in the world of online fitness, where misinformation spreads faster than facts, maybe brutal honesty is exactly what’s needed.

As Dr. Mike puts it:
“I wish you the peace of mind and critical thinking to judge these claims for what they are — so you don’t become another sucker in someone else’s business plan.”
