Brian Johnson, better known as Liver King, is not what he claimed to be. He built a massive following by presenting his muscular physique as the result of eating raw organ meats and following “ancestral” lifestyle habits, but leaked emails in late 2022 revealed he was spending roughly $11,000 per month on anabolic steroids and growth hormone. His core lifestyle principles contain some genuinely good advice, but the physique that sold millions of people on those principles was pharmaceutically built, and several of his dietary recommendations carry real health risks.
The Steroid Revelation
Liver King repeatedly told his audience that his extreme muscularity came from eating raw liver, training hard, and living by ancestral principles. He denied steroid use in interviews, podcasts, and social media comments. In December 2022, fitness YouTuber Derek of More Plates More Dates published leaked emails between Johnson and a bodybuilding coach detailing an extensive regimen of performance-enhancing drugs, including testosterone, growth hormone, and other compounds. Johnson eventually admitted to the drug use in a public apology video.
This matters because his entire brand rested on the idea that ancestral living could produce his physique naturally. The fat-free mass index (FFMI), a ratio of lean body mass to height, has long been used as a rough screening tool for steroid use in resistance-trained men. The traditionally cited natural ceiling is about 25 kg/m², though recent research on large collegiate football players has found some natural athletes reaching 27 to 28. Johnson’s build, at his age and body fat percentage, was widely flagged by fitness professionals as exceeding natural limits well before the emails surfaced.
What He Actually Promotes
Liver King’s brand centers on nine “Ancestral Tenets”: Sleep, Eat, Move, Shield, Connect, Cold, Sun, Fight, and Bond. Stripped of the raw-meat theatrics, several of these are solid, well-supported health principles. Prioritizing sleep, getting regular sunlight, staying physically active, maintaining social bonds, and managing stress are cornerstones of preventive medicine. Cold exposure has a growing body of evidence behind it for mood and metabolic benefits.
The problem is not that every idea is wrong. It’s that these common-sense habits were packaged alongside extreme dietary claims and sold through a physique that was chemically enhanced. The reasonable advice gave credibility to the unreasonable parts, and the unreasonable parts are what drove supplement sales.
The Business Behind the Brand
Liver King is not just a social media personality. He’s the face of a supplement empire reportedly generating around $100 million per year in revenue. His companies sell desiccated organ meat capsules, marketed as a convenient way to get the benefits of eating liver, heart, bone marrow, and other organs without chewing through raw tissue on camera. The viral content of him eating raw liver was, in effect, a marketing funnel for these products. Understanding this financial incentive is essential context for evaluating any health claim he makes.
Raw Organ Meat Risks
One of Liver King’s signature moves is eating raw beef liver on camera. Cooked organ meats can be a genuinely nutrient-dense food, but consuming them raw introduces specific dangers that he rarely acknowledges.
Raw cow liver is a well-documented source of toxocariasis, an infection caused by roundworm larvae. A study of 120 patients with elevated white blood cell counts found that 87.5% of those who tested positive for the parasite had recently eaten raw cow liver, compared to just 25% of those who tested negative. Among patients who ate raw liver four or more times per year, the infection rate was 96.4%. The parasite larvae can migrate through the body and settle in organs including the eyes and brain, sometimes causing permanent damage.
Beyond parasites, raw liver can carry Salmonella, E. coli, and Campylobacter. Cooking destroys these pathogens without meaningfully reducing the vitamin and mineral content that makes liver nutritious in the first place.
Vitamin A Toxicity From Liver
Even cooked, liver consumed in the quantities Liver King promotes can create problems. Beef liver is one of the most concentrated natural sources of preformed vitamin A. Normal dietary amounts are safe, but intake above roughly 40,000 IU per day (about 12,000 micrograms) can become toxic. That threshold is easier to hit than most people realize. A case involving seven-month-old twins who were fed about 120 grams of chicken liver daily resulted in irritability, vomiting, and bulging soft spots on the skull within four months.
Long-term overconsumption is more insidious. One documented case involved a 29-year-old man and a 41-year-old woman who followed a beef liver diet for eight to nine years. One developed cirrhosis, and the other had abnormal liver function tests. The irony of damaging your liver by eating too much liver is hard to miss. Organ meats also tend to be high in cholesterol and saturated fat, which the Cleveland Clinic notes can raise blood cholesterol levels, particularly risky for anyone with existing heart disease factors.
What Science Says About Ancestral Diets
The broader concept of eating and living more like our evolutionary ancestors has legitimate scientific interest, but it’s more nuanced than Liver King presents it. Reviews of paleolithic dietary patterns suggest they can generate useful hypotheses about human nutrition, particularly around calcium intake, protein sources, and the role of physical activity in bone health. But researchers have been careful to note that these patterns are not yet a basis for formal dietary recommendations.
The ancestral framing also cherry-picks which parts of prehistoric life to romanticize. Our ancestors also had average lifespans of 30 to 40 years, high infant mortality, frequent parasitic infections, and no access to medical care. Selectively adopting “ancestral” habits while relying on modern sanitation, medicine, and grocery supply chains is a lifestyle choice, not a return to nature.
The Bottom Line on Legitimacy
Liver King’s physique was built on steroids, not liver. His business model depends on selling supplements through viral content that exaggerates what diet and lifestyle alone can achieve. Some of his underlying principles, like sleeping well, moving your body, getting sunlight, and building community, are genuinely good advice that predates his brand by decades. But his specific dietary recommendations, particularly eating raw organ meats in large quantities, carry documented risks ranging from parasitic infection to vitamin A toxicity and liver damage. The persona was a marketing vehicle, and the product it sold was a fantasy version of what the human body can do without pharmaceutical help.
