Exercise Scientist Exposes Liver King's Diet and Training Claims! | BOXROX
In the ever-evolving world of fitness and health trends, few figures have captured as much attention and controversy as the Liver King. Known for his bold claims about primal living, intense workouts, and unconventional dietary practices, Liver King has amassed a significant following. However, recent scrutiny from exercise scientists, including Dr. Mike of Renaissance Periodization, sheds new light on the validity of these practices.
An Introduction to Liver King’s Controversy
Liver King, or Brian Johnson as he’s known off-screen, has built his brand on a narrative of returning to primal roots through rigorous physical training and a diet he claims mimics ancient practices. Central to his philosophy are “ancestral tenets” which he asserts are crucial for optimal health and fitness.
Dr. Mike, an exercise scientist with a background in sport and exercise science, as well as competitive bodybuilding and Brazilian Jiu-Jitsu, has taken a critical stance. In a recent analysis, Dr. Mike dismantles Liver King’s claims, questioning both their scientific basis and practical application.
Decoding Liver King’s Ancestral Diet and Training
Liver King advocates for a diet rich in organ meats, bone marrow, and other foods he deems essential for primal nutrition. His approach emphasizes consuming the entire animal, from “nose to tail,” which he believes provides a comprehensive spectrum of nutrients vital for health.
However, Dr. Mike highlights the inconsistencies and impracticalities of such a diet in modern contexts. He points out that while organ meats do offer nutritional benefits, there is no scientific evidence supporting the necessity of consuming them exclusively or in such large quantities. Most nutrition experts agree that a balanced diet incorporating a variety of food groups is more effective and sustainable for long-term health.
Moreover, Liver King’s diet ignores modern advances in nutrition science. Contemporary dietary guidelines are based on extensive research, showing that a diet rich in fruits, vegetables, lean proteins, and whole grains promotes overall health and prevents chronic diseases. The hyper-focus on organ meats and other primal foods might also lead to nutritional imbalances and deficiencies if not carefully managed.
The Truth About Liver King’s Training Regimen
Liver King’s training regimen is equally contentious. He promotes intense physical activities like carrying heavy loads over long distances and exposure to extreme cold as ways to enhance strength and resilience. These methods, while invoking a sense of primal toughness, are critiqued by Dr. Mike for their potential risks and limited effectiveness compared to more conventional exercise approaches.
Dr. Mike advocates for evidence-based training methods that prioritize progressive overload, compound movements, and structured rest periods. He argues that these methods not only build strength more efficiently but also reduce the risk of injury associated with extreme training practices. Compound movements like squats, deadlifts, and bench presses are foundational in building muscle and strength because they engage multiple muscle groups simultaneously, promoting functional fitness.
Additionally, the extreme elements of Liver King’s regimen, such as carrying heavy loads over long distances, can lead to overuse injuries and chronic pain. Modern exercise science emphasizes the importance of a balanced workout routine that includes cardiovascular, strength, flexibility, and mobility training to ensure holistic fitness and prevent injuries.
Epigenetics and the Misuse of Scientific Terms
Liver King often references epigenetics to justify his dietary and training choices. However, Dr. Mike clarifies that while epigenetics is a legitimate field of study, Liver King’s application of the term is misleading. Epigenetics refers to the study of how gene expression can be influenced by environmental factors, but it does not validate extreme dietary or training regimes as claimed by Liver King.
The misuse of scientific terms like epigenetics can be misleading for individuals seeking genuine health advice. It’s crucial to understand that while lifestyle factors such as diet and exercise can influence gene expression, these effects are complex and cannot be simplified into blanket statements endorsing extreme behaviors. Reputable health and fitness advice should be grounded in robust scientific evidence, considering the multifaceted nature of human biology.
Shielding and Other Dubious Health Practices
Liver King advocates for shielding against modern environmental “dangers” like Wi-Fi and synthetic clothing, claiming they disrupt natural biological rhythms. Dr. Mike dismisses these claims, citing scientific consensus that these technologies pose no significant health risks when used appropriately.
The idea of shielding oneself from everyday modern conveniences is based more on fear-mongering than scientific reality. Research has shown that everyday exposure to Wi-Fi and synthetic clothing has minimal to no adverse effects on human health. Instead of focusing on these unfounded concerns, individuals should prioritize well-established health practices such as regular physical activity, balanced nutrition, adequate sleep, and stress management.
The Reality Behind the Persona
Beyond the controversies, Liver King’s persona raises questions about authenticity and credibility. Dr. Mike asserts that while Liver King’s message may resonate with some seeking alternative health approaches, his methods lack scientific rigor and may pose risks to followers’ health.
Moreover, the revelations about Liver King’s use of performance-enhancing drugs (PEDs) further undermine his claims of achieving his physique through natural and ancestral means. This discrepancy highlights the importance of transparency and honesty in the health and fitness industry. Aspiring to unrealistic standards set by individuals who do not disclose their use of PEDs can lead to disappointment, disillusionment, and potentially harmful behaviors in those trying to emulate them.
In conclusion, the Liver King phenomenon serves as a cautionary tale in the fitness and health industry. While his charisma and unconventional approach may attract attention, consumers are urged to critically evaluate the scientific basis of health and fitness claims.
Dr. Mike’s analysis underscores the importance of evidence-based practices supported by peer-reviewed research. As consumers navigate the landscape of fitness influencers and health trends, skepticism and informed decision-making are crucial.
For those genuinely interested in improving their health and fitness, Dr. Mike recommends seeking guidance from certified professionals and relying on established principles of exercise science and nutrition.
In the end, the Liver King saga reminds us that while the allure of ancestral lifestyles and extreme fitness practices may be compelling, health decisions should always be grounded in scientific evidence and reasoned analysis.

Exercise ‘snacks’ can keep your fitness on track when time is tight – try these 3 today
December is great for many things – socialising, scoffing, falling out with relatives – but sticking to a training schedule is not one of them.
Heading out the door on Christmas morning for a two-hour long run is likely to put anyone on the naughty list, while it takes a dedicated runner indeed to spend part of the festive period running loops of the track.
What the mere mortal needs is exercise “snacks”. These can be enjoyed/endured alongside the carb-based variety and snuck in to even the busiest Christmas schedule.
A review in Sports Medicine and Health Research confirmed that regular, short bursts of physical activity throughout the day improved cardiovascular respiratory fitness, increased fat oxidation and polished off blood sugar levels after eating.
Vigorous intermittent exercises, such as sprints, were good for building muscle strength. Meanwhile, 10-minute resistance training sessions were found to be particularly beneficial to older people. The researchers concluded that exercise snacks could be a viable alternative to longer, less frequent sessions.
Cram in vigorous bouts of stair climbing for muscle strength, or one or two sub-10 minute morsels for muscle growth as an efficient alternative to meatier long sessions. Here’s some inspo below…

Study shows the antioxidants in this tea improve exercise recovery
I love many different herbal teas just as much as I enjoy a good old-fashioned British cup of PG tips, Earl Grey, or Glengettie — a Welsh favorite from the rolling valleys where I was born. In an interesting study, researchers explored whether drinking green or matcha tea can improve sports performance and exercise recovery, and the results might have you reaching for a vibrant green drink. If you want to get straight to the results, the short answer is that drinking green and matcha tea can support hydration, body fat control, and exercise recovery. Still, it definitely won’t be a game-changer when it comes to your performance in the gym, on the court, or on the field.
Hydrating with tea
In a study published in Nutrition and Food Technology, researchers reviewed existing studies of athletes and active adults that focused solely on drinking tea — no pills or extracts. They revealed that green or matcha tea can help hydrate the body when consumed in normal amounts. Tea counts toward your daily water intake.
Antioxidants and recovery

The research highlighted how the widely-studied antioxidants in green and matcha tea can improve exercise recovery and help protect your cells from the stress associated with intense exercise. That said, the research shows that drinking tea won’t lead to faster or better strength gains, so it’s no silver bullet for helping you achieve your fitness goals. However, they also concluded that low-caffeine green tea could even improve sleep quality, which I would argue could potentially help you power through that workout if you’re getting better sleep the night before.
Linked to lower body fat

Interestingly, the study authors also concluded that drinking around two or three cups of green or matcha tea per day was associated with slightly lower body fat and improved body composition and fat burning. While the effects weren’t overly significant, they were noted in the research. Cup of tea, anyone?

Taylor Swift’s fitness strategy that made 632 days long Eras Tour possible: Her exercise routine to stay energized
Preparing for a Physical Marathon
Before the tour began, Swift recognized the physical challenge she was about to face. “I never would’ve believed you if you told me we were doing a three-and-a-half-hour show. Saying it is one thing, doing it is another,” she admitted in the Disney+ docuseries The End of an Era. For comparison, her longest previous show had lasted just two hours and 15 minutes.
To meet these demands, Swift began training six months ahead of her first rehearsal. Her daily treadmill sessions mirrored the tempo of the songs she would perform live, with faster tracks prompting running and slower songs calling for brisk walks or light jogging. “You just don’t want them to see you panting,” she explained to TIME.
Strength and Conditioning Regimen
While cardio built endurance, strength training ensured she could perform high-energy choreography without fatigue. Under the guidance of longtime trainer Kirk Myers, Swift tackled exercises such as battle ropes, medicine ball throws, assisted pull-ups, sledgehammer workouts, leg raises, and Russian twists. Myers described her as “the most resilient person I have ever met,” highlighting her ability to persevere through challenging workouts.
Swift’s humor surfaced even during difficult exercises. “In no way do I ever apply this … at any point in the show, I just want to flag that as I do every time I have to do pull-ups. Strong dislike. Two thumbs down,” she said, referring to resistance band-assisted pull-ups. She jokingly attributed her increasing strength to “all the pent-up rage and resentment” she felt toward the moves.
Dance Training and On-Stage Precision
Beyond the gym, Swift committed three months to dance rehearsals with choreographer Mandy Moore to ensure every move was second nature. “I wanted to be so over-rehearsed that I could be silly with the fans, and not lose my train of thought,” she shared with TIME. The precision extended to rapid costume changes, often completed in under 1 minute and 15 seconds, with the fastest taking just 39 seconds.
Swift ran an estimated eight miles per show while performing over 40 songs that spanned her musical eras. High-cardio sections, including the 1989 and Reputation sets, were particularly demanding. Yet she described the physical challenge as secondary to the personal purpose the tour provided, especially during a period marked by two breakups.
