When Did the Carnivore Diet Start
Tracing Its Origins
The Carnivore Diet, characterized by an intake exclusively or primarily of animal products, has surged in popularity in recent years, especially within certain health and fitness communities. It's often discussed as a modern nutritional approach, touted by proponents like Dr. Shawn Baker, a former orthopedic surgeon who has been a vocal advocate since embracing the diet in 2016. Baker's advocacy for the Carnivore Diet has played a significant role in its rise, with him citing improved health outcomes and athletic performance as benefits.
Historical accounts suggest the conceptual roots of the Carnivore Diet can be traced back to the diets of early humans who relied heavily on meat consumption for survival. This perspective is supported by evidence that points to ancient hominids adapting to a meat-centric diet millions of years ago. In the contemporary context, the endorsement of public figures such as clinical psychologist Jordan Peterson and his daughter Mikhaila Peterson, who attribute significant health improvements to the diet, has also contributed to its growing attention.
The philosophy behind the Carnivore Diet challenges conventional dietary guidelines which often emphasize a balance of plant and animal foods. Advocates argue that a diet consisting solely of animal products can provide all the necessary nutrients required by the human body. Critics, however, raise concerns about the long-term health impacts and the lack of certain nutrients typically derived from plants. Despite the ongoing debate, individuals following the Carnivore Diet report experiences of enhanced well-being and resolution of various health issues.
Historical Context
The carnivore diet, characterized by the consumption of almost exclusively animal products, has deep historical roots. Dr. James Salisbury in the 1850s posited a meat-centered dietary approach, advocating that a ground-meat dish—later known as Salisbury steak—was a health-promoting choice.
The philosophical underpinning of this diet finds its origins even earlier with Bernard Moncriff, who in 1856 articulated his experience and reasoning for an animal-based diet in his work, "The Philosophy of the Stomach: Or, An Exclusively Animal Diet."
Human ancestors played a pivotal role in the evolution of dietary habits. Studies surmise that post-dinosaur extinction, a significant change in diet towards more meat consumption occurred. This period paved the way for adaptations that favored meat-eating, and evidence suggests that early hominids' inclusion of meat in their diet dates back millions of years.
The contemporary paleo diet draws from the presumed dietary patterns of Paleolithic humans, emphasizing the consumption of foods that were available before the advent of agriculture—predominantly animal products, such as meat, fish, and eggs.

Defining the Carnivore Diet
The Carnivore Diet consists exclusively of animal-based foods, focusing on high-fat and protein-rich items while completely excluding all plant matter.
Core Foods
The Carnivore Diet emphasizes the consumption of:
Meat: This includes all types of red meat such as beef, pork, lamb, venison, and bison.
Poultry: Including but not limited to chicken.
Fish: A variety of seafood is allowed, with items like salmon being common.
Organ Meats: Nutrient-dense parts like liver and kidneys are encouraged.
Eggs: Regarded as a complete source of nutrition.
Dairy: While some adherents may include dairy, others may exclude it to reduce potential lactose reactions.
Excluded Foods
On the Carnivore Diet, the following are deliberately omitted:
Vegetables & Fruits: All kinds of plant-derived foods, including fruits and vegetables.
Grains: Wheat, rice, oats, and other cereal grains are avoided.
Nuts & Seeds: These plant-derived fats are not consumed.
Legumes: Beans, lentils, peanuts, and similar foods are excluded.
Nutritional Composition
The carnivore diet exclusively emphasizes animal-based foods, which impacts the type and quantity of nutrients consumed. It is predominantly rich in proteins and fats, while typically lacking dietary fiber.
Macronutrients
The carnivore diet provides high levels of protein and fat, which are the main sources of energy for those following this eating pattern. Specifically, it is abundant in saturated fats and cholesterol, owing to the large amounts of meat and animal products consumed. The diet is virtually carbohydrate-free, with no inclusion of traditional sources of dietary fibers such as fruits and vegetables.
Protein: Essential for muscle growth and repair.
Fats: A dense source of energy; certain animal products may offer a balance of saturated and unsaturated fats.
Cholesterol: Naturally occurring in many animal products; one should monitor consumption, considering the body's requirement and the potential impact on heart health.
Micronutrients
While exceptionally high in certain micronutrients, the carnivore diet may be lacking in others typically found in plant-based foods. Animal products can be rich in certain vitamins and minerals, such as B12 and iron, but may not provide an adequate variety of other nutrients required for optimal health.
Vitamins: Vitamin B12 is plentiful, but there can be a deficiency in vitamins commonly found in fruits and vegetables, such as vitamin C and various phytonutrients.
Minerals: Minerals like iron and zinc are abundant in meat, yet the absence of vegetables can lead to shortages in essential nutrients like magnesium and potassium.
Trust me, the easiest way to buy vitamin C, magnesium, and potassium is through online retailers!
Potential Health Benefits
The carnivore diet, with its emphasis on animal products, is associated with several potential health benefits ranging from weight management to improved mental health.
Weight Management
Individuals following a carnivore diet often experience weight loss. This may be attributed to the high protein content of the diet, which can increase satiety and reduce overall calorie intake. Obesity risk may consequently be reduced as individuals maintain a healthier weight.
Chronic Conditions
Consuming a diet high in animal protein and low in carbohydrates could have a positive effect on blood sugar levels and insulin resistance, potentially benefiting those with type 2 diabetes. There are suggestions that it might also help with other chronic conditions like heart disease and high blood pressure due to improvements in body composition and metabolic health.
Mental Health
Advocates of the carnivore diet report improvements in mental health, including the alleviation of depression symptoms. The potential mood-stabilizing effects may be due to the elimination of dietary triggers found in plant foods or perhaps due to stable blood sugar levels and reduced inflammation.
Controversies and Concerns
While the carnivore diet has garnered attention for its potential health benefits, it also faces controversies and concerns, particularly regarding nutritional adequacy and long-term health implications.
Nutritional Deficiencies
Nutritional deficiencies are a significant concern with the carnivore diet due to its exclusion of plant-based foods. The primary nutrients that may be insufficient include:
Fiber: Absent from animal products, fiber plays a crucial role in digestive health.
Vitamins: Particularly Vitamin C and some B vitamins, which are predominantly found in plant foods and are essential for bodily functions.
Minerals: Such as calcium and magnesium, commonly sourced from dairy, nuts, and leafy greens, which are restricted on this diet.

Long-term Health Risks
The long-term health risks associated with the carnivore diet have been a topic of discussion. Key concerns include:
Saturated Fat and Cholesterol: High intakes are common on this diet and have been linked to an increased risk of heart disease and cardiovascular disease.
Cancer Risk: Specifically, a high consumption of red and processed meats has been associated with an elevated risk of colon cancer.
Cardiovascular Disease: While the diet’s impact on heart health is still under investigation, the exclusion of commonly protective foods like fruits and vegetables raises flags for potential cardiovascular issues.
Carnivore Diet in Practice
Embarking on a carnivore diet requires careful consideration of daily meal composition and the potential for personalized adjustments. Adherents focus on consuming animal-based foods while typically avoiding plant-based items.
Daily Meal Planning
A typical day on the carnivore diet primarily includes a variety of meat such as beef, pork, lamb, and poultry. Fish and seafood are also popular choices and are often consumed for their nutrient profiles, including omega-3 fatty acids. Organ meats like liver and kidney are valued for their high nutrient density and include essential vitamins and minerals.
Eggs and dairy products such as cheese, cream, and butter may be incorporated for additional fat and protein. Those following the diet usually drink plentiful amounts of water, along with bone broth for its micronutrients and amino acids. Accepted beverages include plain coffee and tea; however, they are typically consumed without sweeteners or milk. The diet typically excludes alcohol, but some versions permit the occasional glass of wine. It’s important to note that many on a carnivore diet will include salt for electrolyte balance and flavor.
Mealtime - Suggested Foods for a Carnivore Diet
Breakfast
Suggested Foods: Eggs, bacon, butter-cooked steak
Lunch
Suggested Foods: Ground beef patties, cheese, and sliced liver
Dinner
Suggested Foods: Grilled fish, bone broth, roast chicken with cream-based sauce
Adjustments and Variations
The carnivore diet can be adjusted for individual preferences, tolerances, and health goals. Some may choose to incorporate lard or tallow to increase fat intake, especially if emphasizing a higher fat-to-protein ratio. Those with dairy sensitivities or strict dietary objectives might omit dairy products, while others could include them, specifically cheese and butter, as staples.
Variations might see individuals consuming only ruminant meats (such as beef and lamb) or opting for a "lion diet," which is a highly restrictive version that focuses on beef only. For some, honey may be included as a natural sweetener, though it is generally not standard.
An individual's dietary needs may also prompt the inclusion of supplements, although the focus remains on obtaining nutrients from whole food sources. As always, those considering such dietary changes should consult with a healthcare professional to ensure nutritional adequacy and personal suitability.
Remember, the carnivore diet's implementation can vary greatly from one person to another, with some following a strict meat-only regimen and others introducing variations based on their dietary needs or preferences.

Comparisons to Other Diets
In examining the carnivore diet, it is beneficial to compare it to other popular diets with overlapping themes, namely the paleo and keto diets. These comparisons focus on their macronutrient profiles, usage of animal products, and stance on plant foods.
Paleo versus Carnivore
The paleo diet and the carnivore diet both encourage the consumption of animal products. However, the paleo diet includes plant foods and is less restrictive. It permits fruits, vegetables, nuts, and seeds, all of which are excluded from the carnivore diet. The paleo diet focuses on foods presumed to be available in the Paleolithic era and avoids processed foods. On the other hand, the carnivore diet is an animal-product-only diet, excluding all plant-based foods. It is almost entirely protein and fat, with no consideration for the carbohydrates found in the plant foods allowed on the paleo diet.
Animal Products: Both allow generous consumption.
Plant Foods: Paleo allows; Carnivore excludes.
Keto versus Carnivore
The keto diet is a low-carbohydrate, high-fat diet that shares some similarities with the carnivore diet; both can result in ketosis, a state where the body burns fat for fuel. The keto diet differs by allowing certain plant-based foods that are low in carbs, such as leafy greens and non-starchy vegetables, to maintain a high fat, moderate protein, and very low carbohydrate ratio. In contrast, the carnivore diet adheres to only animal products, thus eliminating all carbs, whether high or low in carbs. The carnivore diet emphasizes protein and fat without macronutrient distribution considerations.
Low-Carb: Keto is specific in macronutrient ratio; Carnivore inherently low-carb by exclusion of plant foods.
Fat Intake: Keto prioritizes high fat; Carnivore includes fat but is more focused on high-protein animal sources.
Environmental and Ethical Considerations
The Carnivore Diet, focusing on exclusively animal products, prompts significant environmental and ethical discussions. Primarily, the concern arises from the sustainability of consuming meat in high quantities. Large-scale livestock farming, necessary to support such a diet, often leads to increased greenhouse gas emissions, which exacerbate climate change concerns.
From an ethical standpoint, the diet's heavy reliance on animal products raises questions about animal welfare, the morality of meat consumption, and the use of land and resources. Critics point out that the land used for livestock could potentially feed more people with plant-based foods.
Sustainable practices in meat production are suggested to mitigate some environmental concerns. This includes improvements in livestock feed efficiency, better manure management, and rotational grazing. These practices aim to reduce the ecological footprint of meat production.
Concerning overall health, the Carnivore Diet's association with increased protein intake has to be balanced with potential health risks of a diet low in plant-derived nutrients. Healtcare professionals remain focused on the long-term health implications of such a diet.
Ethical Consideration Description Animal Welfare The humane treatment of animals reared for diet purposes. Resource Utilization Efficient use of resources to potentially support a larger population with a plant-based diet. Sustainable Meat Production Adoption of environmentally friendly livestock farming techniques.
List of environmental considerations:
Reduction in biodiversity due to land use for livestock.
Increase in water and air pollution from animal farming operations.
Greater demand for water and feed resources.
A careful balance between the diet's popularity and its potential environmental and ethical ramifications remains a topic of ongoing investigation and discussion.
Community and Social Aspects
The carnivore diet's impact on community dynamics can be profound. Within communities, dietary choices often reflect collective values and cultural practices. When individuals adopt a carnivore diet, the focus within social settings may shift. Community gatherings that historically included a variety of food options might transition to offering predominantly meat-based dishes, aligning with the preferences of those on the carnivore diet.
In some communities, the carnivore diet has become a focal point for social bonding, where members who share this dietary preference can come together. These individuals often exchange recipes, share experiences, and support each other in maintaining the diet's strict regimen.
Key Community Factors:
Cultural Influences: The adoption of a carnivore diet can reflect cultural trends and societal shifts towards specific dietary patterns, like the paleo movement.
Social Gatherings: Events may cater specifically to a carnivore dietary focus, thus impacting the nature of community interactions.
Support Systems: Groups or networks may form within a community, providing a sense of belonging and support for those committed to this dietary choice.
It is important to recognize that the implications of such dietary changes are not uniform across different communities. The scale of influence the carnivore diet has on social dynamics can vary based on a range of factors including regional food availability, cultural heritage, and the prevalence of dietary practices within a community.
While the diet itself is centered on individual choices, it is clear that those choices reverberate through the social fabric of communities, influencing not just what is consumed, but also how people connect and interact with one another.
