Anecdotal reports from 2,029 adults who followed the carnivore diet for at least six months showed 95% reported overall health improvements. This highly restrictive diet, which is a variant of primal and ancestral eating, focuses exclusively on animal products like meat, fish, and eggs.

Quick Summary

An exploration of the carnivore diet, a strict, all-animal product eating plan embraced by some within the primal and ancestral health communities. It involves consuming only meat, fish, eggs, and certain dairy, aiming to eliminate all plant-based foods.

Key Points

Carnivore is a Sub-Set of Primal Eating: While Primal includes a variety of whole foods, the carnivore diet is a highly restrictive, meat-only version embraced by some within the broader ancestral health movement.
Diet Consists Exclusively of Animal Products: Allowed foods include meat (nose-to-tail), fish, eggs, and optionally, low-lactose dairy and animal fats.
Zero-Carbohydrate Approach: By eliminating all plant-based carbohydrates, the diet aims to trigger ketosis for weight loss and metabolic health benefits.
Addresses Inflammation and Autoimmune Issues: Many followers report a reduction in inflammation, skin issues, and autoimmune symptoms by removing common plant irritants.
Faces Criticism for Potential Risks: Health concerns include nutrient deficiencies, lack of fiber, high saturated fat intake, and potential kidney strain.
Often Used as an Elimination Protocol: The diet can serve as a temporary reset to identify food sensitivities before reintroducing plant foods.
Limited Scientific Research: Most claims regarding benefits are anecdotal; more robust, long-term studies are needed to confirm safety and efficacy.
Differs from Paleo/Primal: Unlike broader ancestral approaches, it excludes all plant foods like vegetables, fruits, and nuts.

Defining the Carnivore Diet in a Primal Context

The carnivore diet, particularly for those in the primal health community, is an eating plan that consists exclusively of animal products. While the broader primal blueprint emphasizes a whole-foods approach that includes vegetables, fruits, and nuts alongside animal protein, the carnivore diet takes this concept to its most extreme conclusion by removing all plant matter. Adherents consume meat, fish, eggs, and some select dairy, arguing this pattern most closely mimics the diet of early human ancestors and promotes optimal health by eliminating inflammatory plant compounds and carbohydrates.

The Foundational Principles of Carnivore Eating

The philosophy behind the carnivore diet is rooted in the belief that human ancestral populations, particularly in certain geographical locations and periods, thrived on predominantly meat-based diets. Proponents like former orthopedic surgeon Shawn Baker have popularized the idea, suggesting that our modern, high-carbohydrate diets are the root cause of many chronic diseases. By stripping the diet down to zero carbohydrates, the body is forced to use fat and protein for energy, a state known as ketosis. Followers believe this can lead to benefits such as weight loss, improved mental clarity, and reduced inflammation. However, it is important to note that robust, controlled scientific studies are limited, and many claims are based on anecdotal evidence.

What to Eat on a Carnivore Diet

Unlike other ancestral diets that include a variety of foraged plants, the carnivore diet’s food list is straightforward. The diet focuses on consuming nose-to-tail, which includes organ meats, considered crucial for obtaining a wide range of vitamins and minerals.

The Allowed Foods List

Meat: All types of meat are permitted, including beef, pork, lamb, and chicken. High-fat cuts are often emphasized to meet energy needs.
Organ Meats: Liver, kidney, and heart are encouraged for their high nutrient density.
Fish and Seafood: Salmon, mackerel, sardines, shrimp, and crab are excellent sources of protein and Omega-3 fatty acids.
Eggs: A staple of the diet, eggs from various poultry are consumed.
Dairy (Optional): Some adherents include low-lactose dairy products like hard cheeses, butter, and heavy cream, while purists avoid all dairy.
Fats: Lard, tallow, and ghee are used for cooking.
Salt: Used for seasoning, while many other spices and herbs are avoided.
Beverages: Only water and bone broth are allowed for strict carnivores, though some include coffee or tea.

Potential Benefits and Risks of the Carnivore Diet

The carnivore diet is not without its proponents and critics. While anecdotal evidence points to certain benefits, health professionals raise concerns about its long-term effects.

Potential Advantages

Metabolic Effects: By eliminating carbohydrates and sugar, it can help regulate blood sugar, improve insulin sensitivity, and promote weight loss.
Reduced Inflammation: Many followers report a reduction in inflammation, which they attribute to the removal of plant-based irritants like oxalates and lectins. This can lead to improvements in autoimmune and skin conditions.
Simplified Eating: The restrictive nature of the diet can simplify meal preparation and decision-making, helping people overcome food addiction.

Notable Health Concerns

Nutrient Deficiencies: Excluding all plant foods can lead to deficiencies in fiber, Vitamin C, and antioxidants. While organ meats can provide some missing nutrients, a varied plant-based diet offers a broader spectrum.
Digestive Issues: The complete lack of fiber can disrupt gut microbiota balance and lead to constipation.
Heart Health: High intake of saturated fats and cholesterol could potentially increase the risk of heart disease, though the link between saturated fat and heart disease is still debated.
Kidney Stress: Excessive protein consumption can put a strain on the kidneys, especially for individuals with pre-existing conditions.

Carnivore Diet vs. Broader Primal or Ancestral Approaches


Feature	Carnivore Diet	Broader Primal/Ancestral Approach
Plant Foods	Strictly prohibited.	Included; vegetables, fruits, nuts, and seeds are encouraged.
Carbohydrates	Zero-carb approach; relies on fat for energy.	Low-carb, but not zero; includes carbs from whole plant sources.
Dairy	Allowed in some variations (low-lactose).	Raw or fermented whole-fat dairy is generally permitted.
Processed Foods	Prohibited.	Prohibited.
Lifestyle Focus	Primarily dietary restriction.	Holistic, includes diet, movement, sleep, and sun exposure.
Evolutionary Basis	Romanticizes a highly speculative, meat-only ancestral diet.	Acknowledges humans were diverse omnivores.

A Sample Carnivore Diet Meal Plan

A typical day on a carnivore diet emphasizes high-fat, high-protein meals. A focus on fatty cuts of meat and nose-to-tail eating helps ensure adequate calorie and nutrient intake. Meal timing is flexible, with many followers eating only two or three meals a day, or even practicing intermittent fasting.

Sample Day for a Carnivore Adherent

Breakfast: Scrambled eggs cooked in butter, with bacon.
Lunch: A large, fatty cut of steak, such as a ribeye.
Dinner: Broiled salmon fillets with a side of beef liver.
Snacks: Beef jerky or hard-boiled eggs.
Beverages: Water and bone broth throughout the day.

The Role of the Carnivore Diet as an Elimination Tool

Some individuals in the primal community do not adhere to the carnivore diet long-term but use it as an intensive elimination protocol. This approach involves removing all potential food irritants (including plants) to identify which foods cause issues. After a period of pure carnivore eating, individuals can gradually reintroduce specific food groups to gauge their body's reaction. This method can help pinpoint food sensitivities and customize a more sustainable, less restrictive primal diet moving forward.

Conclusion: Evaluating the Carnivore Diet for Primal People

The carnivore diet for primal people is a significant departure from the broader ancestral eating philosophy, representing a strict, zero-carb interpretation. While it offers anecdotal benefits like weight loss and reduced inflammation for some, particularly when used as a short-term elimination tool, it also presents notable risks such as potential nutrient deficiencies and digestive problems. For those committed to ancestral health, understanding the nuanced difference between this ultra-restrictive approach and more balanced primal lifestyles is crucial. Ultimately, the decision to pursue a carnivore diet should be made with careful consideration of personal health goals, potential risks, and ideally, in consultation with a healthcare professional. Exploring ancestral health can include many dietary paths, not all of which require such extreme food limitations.

Frequently Asked Questions

The primary difference is the inclusion of plant-based foods. While a broader primal diet allows for vegetables, fruits, nuts, and seeds, the carnivore diet is strictly limited to animal products, excluding all plant matter.

Some versions of the carnivore diet permit low-lactose dairy like hard cheeses, butter, and heavy cream. However, purists or those with dairy sensitivities typically avoid all dairy products.

The most significant risks include potential deficiencies in fiber, Vitamin C, and antioxidants, which are found in plant foods. Other concerns involve high saturated fat intake and stress on the kidneys.

Carnivore diet adherents believe that fiber is not an essential nutrient for human health. While some may experience initial digestive issues, others report improved digestion by eliminating plant-based irritants, though the lack of fiber can lead to gut microbiome imbalance.

Most of the evidence supporting the carnivore diet is anecdotal. There is limited robust, long-term scientific research on its effects, and many health professionals express concern over its highly restrictive nature and potential risks.

While not strictly required, many carnivore diet proponents emphasize eating organ meats, such as liver, to ensure a broader intake of essential vitamins and minerals that might be less concentrated in muscle meats.

The transition period, often called 'keto flu' or 'carnivore flu,' can involve side effects such as fatigue, sluggishness, and digestive changes as the body switches from using carbohydrates to fats for fuel.
