What is the Carnivore Diet?
Often typed as 'What is the Carnval diet?', the Carnivore diet is a highly restrictive eating plan that consists exclusively of animal products. Proponents believe that human ancestors primarily consumed meat and fish, and that modern chronic diseases are linked to the introduction of plant-based carbohydrates. The core of the diet is eliminating all plant-based foods—including fruits, vegetables, grains, legumes, nuts, and seeds—to rely solely on animal-derived sources for nutrition. The diet is a more extreme form of a ketogenic diet, with the goal of achieving zero carbohydrate intake. By removing carbs, the body enters a metabolic state called ketosis, where it burns fat for energy instead of glucose.
The Principles and Allowed Foods
Adherents to the Carnivore diet focus on high-protein and high-fat intake from animal sources. The diet is prized for its simplicity, as it eliminates the need for complex meal planning and carb counting common with other dietary approaches.
What to eat on the Carnivore diet
- Meat: Red meats like beef, lamb, and pork are staples. Organ meats such as liver, kidney, and bone marrow are encouraged for their dense nutritional profile, including vitamin C which is scarce elsewhere in the diet.
- Poultry: Chicken and turkey are approved.
- Fish and Seafood: All fish, including fatty fish like salmon and mackerel, are permitted, along with shellfish like shrimp and crab.
- Eggs: Eggs are a nutritional powerhouse and a staple for many on the diet.
- Animal Fats: Lard, tallow, butter, and ghee are primary fat sources.
- Dairy: Low-lactose dairy products, such as hard cheeses, butter, and heavy cream, are often allowed in limited quantities by some followers.
- Seasoning: Salt and pepper are typically permitted.
What to avoid on the Carnivore diet
All plant-derived foods are off-limits, which means a significant number of common food items are eliminated. This includes:
- Vegetables: All vegetables, from leafy greens to root vegetables.
- Fruits: All fruits, including berries and citrus.
- Grains: Wheat, rice, oats, and products made from them, like bread and pasta.
- Legumes: Beans, lentils, and peanuts.
- Nuts and Seeds: All nuts and seeds.
- Sugars and Processed Foods: Any food with added sugars, sweeteners, or processed ingredients.
- Beverages: Coffee, tea, sodas, and juices.
Potential Benefits and Significant Risks
Advocates of the Carnivore diet often cite anecdotal evidence of improved health, but scientific research is limited, and a high-quality, controlled study on its effects has yet to be conducted.
Reported benefits
- Weight Loss: The high protein and fat content promote satiety, leading to reduced calorie intake. The elimination of carbs also causes an initial loss of water weight.
- Improved Blood Sugar: By removing all carbohydrates, the diet can lead to more stable blood glucose levels, which can benefit individuals with type 2 diabetes.
- Reduced Inflammation: Some followers report reduced inflammation and symptom relief for autoimmune conditions by eliminating potential plant-based food triggers.
- Mental Clarity: Some report increased mental focus and stable energy levels, potentially due to consistent blood sugar and a steady supply of nutrients like B12.
Potential risks and downsides
- Nutrient Deficiencies: Eliminating all plant foods means missing out on vital nutrients like vitamin C, fiber, and beneficial plant compounds (antioxidants, phytonutrients). Long-term deficiency could lead to health issues.
- High Saturated Fat and Cholesterol: Consuming large quantities of animal products can lead to high intake of saturated fat, which has been linked to increased LDL ('bad') cholesterol and a higher risk of heart disease.
- High Sodium Intake: Many processed meats contain high levels of sodium, potentially increasing the risk of high blood pressure and kidney disease.
- Lack of Fiber: The complete absence of fiber can cause digestive issues like constipation and negatively impact gut microbiome health.
- Kidney and Gout Risk: High protein intake can put stress on the kidneys, especially for those with existing kidney issues. High intake of meat and seafood can also raise the risk of gout.
- Sustainability Issues: The diet is highly restrictive, making it difficult to maintain long-term, and some may develop disordered eating patterns.
Carnivore Diet vs. Ketogenic Diet
While both the Carnivore and Ketogenic (Keto) diets are low-carb, high-fat plans, they have key differences in their food allowances and restrictiveness.
| Feature | Carnivore Diet | Ketogenic Diet |
|---|---|---|
| Primary Macronutrient | Primarily protein and fat from animal products. | High fat, moderate protein, and very low carbohydrates. |
| Food Sources | Only animal products: meat, fish, eggs, some dairy. | Animal products, some dairy, plus most fruits and vegetables are excluded. |
| Carbohydrate Limit | Aims for zero carbohydrates. | Restricts carbohydrates to a very low level, typically under 50g per day. |
| Exclusions | All plant-based foods: fruits, vegetables, grains, legumes, nuts, seeds. | Grains, sugars, most fruits, potatoes, and some starchy vegetables are excluded. |
| Dietary Flexibility | Extremely restrictive. | More flexible, allowing for plant-based fats, fibrous vegetables, nuts, and seeds. |
| Key Concern | Nutrient deficiencies (fiber, vitamins), long-term health risks. | Often focused on macro counting and staying in ketosis, still potentially nutrient-poor if not carefully planned. |
Is the Carnivore Diet Right for You?
Considering the restrictive nature and potential health risks, consulting a healthcare professional or a registered dietitian is crucial before beginning a Carnivore diet, especially for individuals with pre-existing conditions like kidney disease or a history of disordered eating. They can help assess individual health needs, monitor for deficiencies, and determine if this diet is appropriate. While some anecdotal reports suggest benefits for certain individuals, these findings lack robust scientific backing and should be viewed with caution. A balanced diet with a variety of nutrient-rich foods is generally considered more sustainable and beneficial for long-term health.

Conclusion
The Carnivore diet, often mistakenly called the Carnval diet, is a nutritional plan centered on consuming only animal products and eliminating all plant-based foods. While some followers report benefits like weight loss and reduced inflammation, health experts raise significant concerns about potential nutrient deficiencies, high saturated fat and sodium intake, and the long-term sustainability of such a restrictive plan. Without robust, long-term clinical research, the purported benefits are largely anecdotal. Individuals considering this diet should seek medical advice and weigh the potential short-term gains against the considerable long-term health risks and nutritional imbalances.
