The Belleview Hospital All-Meat Diet Experiment: One Year of Carnivore Living Without Scurvy
In 1928, an extraordinary nutritional experiment unfolded at New York's Belleview Hospital. Two bold participants, Arctic explorer Vilhjalmur Stefanson and his colleague Carlston Anderson, embarked on a year-long scientific study consuming only meat and water. This groundbreaking research challenged conventional wisdom about human dietary requirements and nutrition, as medical professionals monitored the subjects closely throughout their unconventional regimen.
The experiment yielded surprising results that contradicted many established nutritional theories of the time. Both participants maintained excellent health without consuming fruits, vegetables, or carbohydrates. Their physical examinations showed no deficiencies, their weight remained stable without calorie counting, and they reported improved mental clarity and digestion. Particularly notable was the absence of scurvy—a condition many experts had predicted would inevitably develop on an all-meat diet.

Overview of the Bell View Study of 1928
The Bell View study of 1928 represents a groundbreaking nutritional experiment conducted at New York's Belleview Hospital. Two men, Vilhjalmur Stefansson and Karsten Anderson, voluntarily subjected themselves to a year-long all-meat diet under medical supervision. This experiment came about after Stefansson's experiences living with the Inuit, where he observed their meat-based diet and excellent health.
The study protocol was strict and comprehensive. Participants consumed only meat, fat, and water for the entire year with no deviations. Medical professionals monitored their health continuously throughout the experiment to document any changes or adverse effects.
Key findings from the study revealed several important nutritional insights. First, the researchers discovered that fat consumption was essential—without adequate fat intake, protein poisoning (sometimes called "rabbit starvation") could occur. Second, contrary to conventional wisdom, the all-meat diet provided complete nutrition without supplementation.
The health outcomes observed were particularly notable:
Improved disease resistance
Stable weight maintenance without calorie counting
Enhanced mental clarity and focus
Better digestion with reduced digestive discomfort
No development of scurvy despite the absence of plant foods
After adapting to the diet, both participants reported no cravings for carbohydrates or plant foods. Their bodies appeared to function optimally on the meat-based nutrition alone, challenging the prevailing nutritional theories of the time.
The significance of this study lies in its controlled environment and duration. While many nutritional studies last only weeks, this year-long experiment provided substantial data about long-term effects of an exclusive animal-based diet on human health.
Meet the Participants: Stefanson and Anderson
In 1928, during the height of the Roaring Twenties, two men embarked on a groundbreaking dietary experiment at New York's Belleview Hospital. Vilhjalmur Stefanson, an Arctic explorer who had lived among the Inuit people, and Carlston Anderson volunteered to consume nothing but meat and water for an entire year.
Stefanson's time with the Inuit had already exposed him to a meat-based diet. Upon returning to mainstream society, he faced significant skepticism about the viability of such a diet. Medical professionals and nutritionists predicted health disasters, including scurvy and other deficiency diseases.
The experiment was conducted under strict medical supervision. Both men were closely monitored throughout the year, with doctors documenting every aspect of their health and physical condition. This protocol ensured the scientific validity of the results and prevented any deviations from the all-meat regimen.
Key Facts About the Participants:
Stefanson had previous experience with an all-meat diet during his time living with Inuit communities
Anderson joined as the second participant to strengthen the study's findings
Both men voluntarily confined themselves to hospital supervision for a full year
Their only sustenance consisted of meat, fat, and water
Their diet notably included a significant amount of fat alongside protein. This balance proved crucial to their success, as they avoided the protein poisoning (sometimes called "rabbit starvation") that can occur when consuming only lean meat without adequate fat.
Throughout the experiment, both men maintained stable weight without calorie counting. They reported improved mental clarity, enhanced energy levels, and better digestion. Perhaps most surprisingly to the medical community, neither participant showed any signs of vitamin deficiencies, including the expected scurvy.
The Belleview study challenged prevailing nutritional dogma of the time. While most medical professionals expected the participants to experience declining health, Stefanson and Anderson instead demonstrated improved resistance to illness and optimal physiological functioning throughout the experiment.
Dietary Protocol: Meat and Water Only
The carnivore diet, consisting solely of meat and water, has historical significance dating back to a groundbreaking experiment conducted at Bellevue Hospital in 1928. Two men, Vilhjalmur Stefansson and Karsten Anderson, voluntarily subjected themselves to medical supervision for an entire year while consuming nothing but meat, fat, and water.
This experiment demonstrated several key findings about an all-meat dietary approach. First, fat consumption is critically important when following this protocol. Without adequate fat intake, individuals risk developing protein poisoning, historically observed in those who consumed only lean rabbit meat.
The study participants maintained excellent health throughout the experiment. Their bodies obtained all necessary nutrients from animal products alone, without supplementation. This challenges conventional nutritional wisdom that suggests plant foods are essential for complete nutrition.
Notably, after an adaptation period, neither man experienced cravings for carbohydrates or plant foods. Their bodies adjusted to utilizing fat as the primary energy source rather than glucose.
Key Observations from the Bellevue Study Details Mental clarity Improved focus and mood Weight management Natural stabilization without calorie counting Digestive health Reduction in bloating and gastrointestinal issues Disease resistance Enhanced immune function and overall vitality No nutritional deficiencies All essential vitamins and minerals obtained
The participants' health markers remained excellent throughout the study period. Contrary to predictions from skeptics, they showed no signs of vitamin C deficiency (scurvy) despite consuming no fruits or vegetables. This suggests that fresh meat contains sufficient amounts of essential nutrients when consumed appropriately.
For those considering this dietary approach, the critical component is adequate fat consumption. Lean protein alone is insufficient to maintain health on a carnivore protocol. Fattier cuts like ribeye steak provide a natural balance of nutrients that the body can efficiently process.
Key Findings from the Experiment
Importance of Dietary Fat
The experiment revealed that fat consumption is crucial when following a meat-based diet. Participants discovered that protein alone was insufficient for optimal health. The researchers observed symptoms similar to "rabbit starvation" or protein poisoning in cases where lean meat was consumed without adequate fat. Fatty cuts like ribeye or adding butter to leaner cuts proved essential for maintaining energy and preventing nutritional deficiencies.
Nutritional Completeness of Animal Foods
The year-long study demonstrated that all nutritional requirements can be met through animal products alone. Participants received complete nutrition without supplementation or plant foods. Their bloodwork and physical examinations confirmed they obtained sufficient vitamins, minerals, and other essential nutrients exclusively from meat. This contradicted the prevailing belief that diverse food groups are necessary for complete nutrition.
Improved Disease Resistance
Both participants experienced notable improvements in immune function during the experimental period. They reported fewer illnesses and enhanced overall health indicators. Their energy levels remained consistently high throughout the study. Medical staff monitoring the experiment documented improvements in various health markers related to immune system function and resilience against common illnesses.
Absence of Carbohydrate Cravings
After an initial adaptation period, the participants reported no desire for carbohydrate-containing foods. This lack of cravings appeared physiological rather than psychological in nature. Neither man expressed wanting bread, sugar, vegetables, or other non-meat foods throughout the majority of the experimental period. Their satisfaction with the all-meat diet increased as their bodies fully adapted.
Cognitive Performance Improvements
The study participants experienced significant mental benefits while following the all-meat protocol. They reported enhanced focus, improved mood, and increased productivity throughout the experimental period. Unlike the common post-meal energy crashes associated with carbohydrate consumption, the participants maintained consistent mental clarity. Researchers noted these cognitive improvements in their regular assessments.
Natural Weight Management
Both participants maintained their ideal body weight without deliberate calorie restriction or macronutrient tracking. They simply ate according to hunger signals until satisfied. This natural weight regulation occurred without conscious effort on their part. The researchers observed that body composition remained optimal throughout the study period despite unrestricted meat consumption.
Digestive System Optimization
The experiment documented remarkable improvements in digestive function for both participants. Common digestive complaints like bloating and gas were notably absent during the study. The researchers found that contrary to popular belief, animal proteins were efficiently processed by the digestive system. Both men reported comfortable digestion throughout the experimental period.
Vitamin C Requirements Met
Despite consuming no fruits or vegetables for a full year, neither participant developed scurvy or showed any signs of vitamin C deficiency. This contradicted the prevailing medical expectation that scurvy would inevitably develop without plant food consumption. Blood tests confirmed adequate vitamin C levels were maintained through the trace amounts present in fresh meat, particularly when consumed in sufficient quantity.
Medical Misconceptions and Nutritional Ignorance
The Bellevue Hospital study of 1928 represents one of the most significant yet overlooked experiments in nutritional science. Two men, Vilhjalmur Stefansson and Karsten Anderson, voluntarily confined themselves to a hospital for a full year while consuming nothing but meat, fat, and water under medical supervision. This experiment emerged after Stefansson's time living with the Inuit, where he observed their predominantly animal-based diet and excellent health.
Medical professionals of the time predicted severe nutrient deficiencies, particularly scurvy. Instead, both men maintained good health throughout the experiment, with no signs of nutrient deficiencies. Their vital signs remained stable, and medical tests showed normal functioning across all body systems.
The study revealed several important nutritional facts that challenge conventional wisdom.
Key Findings from the Bellevue Study:
Fat consumption is crucial when eating primarily animal products
All nutrient needs can be met through animal foods alone
Improved resistance to common illnesses
No cravings for carbohydrates after adaptation period
Enhanced mental clarity and focus
Natural weight stabilization without calorie counting
Improved digestive function with reduced bloating
The adequate consumption of fat proved essential in the experiment. Without sufficient fat intake, protein poisoning (historically known as "rabbit starvation") can occur when people attempt to survive on lean meat alone. This explains why traditional cultures placed high value on fatty cuts and animal fats.
Despite the absence of fruits and vegetables, neither participant developed scurvy or other deficiency diseases. This contradicts the common belief that vitamin C must come from plant sources. Animal tissues contain small but sufficient amounts of vitamin C and other essential nutrients when consumed in their natural state.
Both men reported increased energy levels and mental clarity throughout the experiment. Their weight naturally stabilized without any deliberate portion control or calorie counting. Simply eating until satisfied proved sufficient for maintaining optimal body composition.
Medical education typically focuses on disease management rather than nutritional optimization, which partly explains why this important study receives little attention in modern medical training. The results challenge many current nutritional dogmas and suggest that conventional dietary advice may need reassessment.
Implications for Current Carnivore Diets
The 1928 Bellevue Hospital study provides valuable insights for individuals following carnivore diets today. The year-long experiment with Stefansson and Anderson demonstrated several key principles that remain relevant nearly a century later.
Fat consumption is essential when following a meat-based diet. Without adequate fat intake, individuals risk protein poisoning, historically known as "rabbit starvation." This condition occurs when people consume too much lean meat without sufficient fat. Modern carnivore dieters should prioritize fatty cuts like ribeye steaks or add butter to leaner meats.
The study challenges conventional nutritional wisdom about vitamin and mineral requirements. Both participants maintained optimal health without supplementation, suggesting meat can provide complete nutrition when consumed properly. This includes trace amounts of vitamin C and B vitamins sufficient to prevent deficiency diseases like scurvy.
Disease resistance appears to improve on carnivore diets. The participants reported fewer illnesses and better overall health throughout the year-long study period. Modern followers often report similar improvements in immune function.
Notable findings from the study include:
Absence of carb cravings: After adaptation, neither participant desired bread, sugar, or vegetables
Enhanced mental clarity: Improvements in focus, mood, and productivity were observed
Natural weight management: Both men maintained ideal weights without counting calories
Improved digestion: Reduction in bloating, gas, and digestive disturbances
These outcomes contradict common concerns about all-meat diets. The participants' health markers remained stable or improved throughout the study period, challenging the notion that plant foods are necessary for optimal health.
The medical establishment's limited emphasis on nutritional education may explain why this study isn't more widely discussed. Most healthcare providers receive minimal training in preventative nutrition and metabolic health, focusing instead on disease management.
For those considering or currently following carnivore diets, the Bellevue study underscores the importance of proper implementation. Adequate fat consumption remains the cornerstone of this dietary approach, serving as the primary energy source and preventing protein overload.
Key Findings from the 1928 Bellevue Study
The 1928 Bellevue Hospital study conducted by Vilhjalmur Stefansson and Karsten Anderson stands as a remarkable experiment in nutritional science. These two individuals voluntarily confined themselves to a hospital setting for an entire year, consuming nothing but meat, fat, and water. Their experience yielded several significant findings that challenge conventional nutritional wisdom.
Fat consumption proved essential on this diet. The study demonstrated that protein alone is insufficient; adequate fat intake prevents "rabbit starvation" or protein poisoning. This explains why fatty cuts like ribeye are particularly valued in meat-based diets.
Contrary to prevailing nutritional theories, both participants maintained complete nutrition without plant foods. Their bodies received sufficient vitamins, minerals, and other nutrients solely from animal products. Meat contains trace amounts of vitamin C and provides B vitamins and minerals necessary for optimal health.
The participants' health profiles showed noteworthy improvements. They experienced enhanced disease resistance, consistent energy levels, and improved digestion. Neither man developed scurvy despite the absence of fruits and vegetables in their diet.
Additional Notable Observations:
After adaptation, carbohydrate cravings disappeared entirely
Mental clarity and focus significantly improved
Body weight naturally stabilized without calorie counting
Digestive issues like bloating and gas resolved
These findings remain relatively unknown in conventional medical education, which typically emphasizes disease management rather than nutritional approaches to health optimization. The study suggests that a properly formulated meat-based diet with adequate fat can support complete nutrition and potentially improve various aspects of health.
