What is the Keto Carnivore (Ketovore) Diet?
The keto carnivore diet, often called "ketovore," is a dietary approach that merges the high-fat, low-carbohydrate principles of the ketogenic diet with the animal-product focus of the carnivore diet. Unlike a strict carnivore diet, which eliminates all plant-based foods, the ketovore diet offers more flexibility by including a small number of low-carb plant items like certain vegetables, berries, and seasonings. The primary goal is to achieve and maintain a state of ketosis, where the body burns fat for energy instead of glucose.
What are the Keto Carnivore Rules?
To successfully follow a keto carnivore diet, understanding the core rules and restrictions is essential. The guidelines are simple but require strict adherence to achieve the desired metabolic state.
Rule #1: Prioritize Animal Products
The foundation of the ketovore diet is animal-based foods. This includes muscle meats from various animals, fish, eggs, organ meats, and animal fats. Proponents suggest opting for high-quality, ethically-sourced animal products like grass-fed beef and pastured eggs, as they may offer a better nutrient profile.
Rule #2: Maintain a Very Low Carbohydrate Intake
The goal is to keep your carbohydrate intake low enough to induce ketosis. While traditional keto allows up to 50 grams of net carbs daily, the ketovore approach typically aims for a stricter limit, often under 20 grams, which aligns more closely with the carnivore end of the spectrum.
Rule #3: Limit Non-Animal Foods to Select Options
Unlike the standard carnivore diet, ketovore permits some low-carb plant foods for nutritional benefits and palatability. These include:
- Low-carb vegetables: Leafy greens (spinach, lettuce), cruciferous vegetables (broccoli, cauliflower), and zucchini.
- Low-sugar fruits: Small amounts of berries (blueberries, raspberries, strawberries).
- Healthy oils: Coconut oil, olive oil, and avocado oil are sometimes used, along with animal fats like tallow and lard.
Rule #4: Avoid All Processed and High-Carb Foods
This rule is non-negotiable. The diet eliminates all processed foods, refined sugars, grains, legumes, and high-carb vegetables and fruits. The exclusion of these foods is believed to reduce inflammation and stabilize blood sugar levels.
Rule #5: Listen to Your Body's Hunger Cues
One of the main tenets is to eat when you are hungry and stop when you are full, rather than adhering to a strict meal schedule or calorie count. The high-fat and high-protein content of the diet is highly satiating, which naturally leads to reduced calorie consumption and fewer cravings.
Allowed and Excluded Foods for Ketovore
The following lists provide a clear guide to what you can and cannot eat on a keto carnivore diet.
Allowed Foods:
- Meat: All types of meat, including beef, pork, lamb, poultry, and wild game.
- Organ Meats: Liver, kidney, heart, and tongue are highly encouraged for their nutrient density.
- Fish and Seafood: Fatty fish like salmon and sardines, as well as shellfish, are excellent sources of omega-3s.
- Eggs: A staple of the diet and a great source of protein and fat.
- Animal Fats: Tallow, lard, and duck fat for cooking and flavor.
- Dairy (Low-lactose): Butter, ghee, hard cheeses, and heavy cream are acceptable in moderation.
- Low-Carb Plants: Small amounts of non-starchy vegetables (spinach, broccoli), berries, and herbs/spices are allowed.
- Drinks: Water, bone broth, and possibly coffee or tea.
Excluded Foods:
- Grains: Wheat, rice, oats, bread, and pasta.
- Legumes: Beans, lentils, and peas.
- High-Carb Fruits: Apples, bananas, oranges, and most fruits outside of small portions of berries.
- Starchy Vegetables: Potatoes, yams, and corn.
- Nuts and Seeds: While keto-friendly, they are often excluded on a stricter ketovore approach to minimize plant intake.
- Processed Foods: All snacks, sweets, and packaged foods with added sugars or non-animal ingredients.
Keto Carnivore vs. Other Diets: A Comparison
| Feature | Keto Carnivore (Ketovore) | Traditional Ketogenic Diet | Strict Carnivore Diet |
|---|---|---|---|
| Carbohydrate Intake | Ultra-low (typically <20g net carbs) | Low (typically 20-50g net carbs) | Zero carbs |
| Allowed Foods | Animal products + limited low-carb plants | Animal products + various plant foods | Exclusively animal products |
| Plant-Based Foods | Limited to non-starchy vegetables and berries | Includes a wide range of low-carb vegetables, nuts, and seeds | Excludes all plant foods |
| Ketosis | The primary metabolic state | The primary metabolic state | Induced by default due to zero-carb intake |
| Flexibility | Moderate (more than strict carnivore, less than traditional keto) | High (within carb limits) | Very low |
| Sustainability | Variable; often more sustainable than strict carnivore | Higher than carnivore due to food variety | Challenging for many due to severe restrictions |
Benefits of a Keto Carnivore Approach
Adopting a keto carnivore lifestyle may offer several potential benefits, though research on this specific hybrid diet is limited.
- Metabolic Effects: By eliminating nearly all carbohydrates, the body transitions into a state of ketosis, burning stored fat for fuel. This can lead to effective weight loss and better blood sugar management.
- Reduced Inflammation: Many followers report a reduction in inflammation, potentially due to the removal of plant-based compounds (like lectins and oxalates) that can trigger immune responses in some individuals.
- Simplicity and Satiety: The diet is simple to follow due to its limited food list, reducing the mental burden of meal planning. High protein and fat content promote satiety, which helps control appetite and reduce overall caloric intake.
- Mental Clarity: Some people report improved mental clarity and cognitive function, potentially linked to the stable energy supply from ketones.
Risks and Considerations
Despite the purported benefits, the keto carnivore diet carries significant risks and is not suitable for everyone. It is highly recommended to consult with a healthcare professional before starting.
- Nutrient Deficiencies: A diet so low in plant-based foods can lack essential nutrients, including fiber, Vitamin C, Vitamin K, and certain phytonutrients. While organ meats and supplements can help, a lack of dietary diversity remains a concern.
- Digestive Issues: The complete lack of fiber can lead to constipation or other digestive problems, as fiber is crucial for gut health and regular bowel movements.
- Cardiovascular Health Concerns: The high intake of saturated fats from animal products may be a concern for cardiovascular health, potentially raising LDL (bad) cholesterol levels in some individuals.
- Kidney Stress: The high protein load can place a strain on the kidneys, especially for those with pre-existing kidney issues.
- Long-Term Viability: The restrictive nature can make it difficult to maintain long-term, leading to potential nutrient gaps and social challenges.
Transitioning to a Keto Carnivore Diet
If you choose to proceed, a gradual transition can make the process smoother.
- Start with a Standard Keto Diet: Begin by first adopting a standard ketogenic diet to let your body adapt to using fat for fuel and reduce carb cravings.
- Gradually Reduce Plant Foods: Over several weeks, progressively eliminate more plant-based foods, such as nuts, seeds, and high-sugar berries, eventually limiting yourself to only low-carb vegetables and berries.
- Introduce Organ Meats: Incorporate nutrient-dense organ meats like liver and heart to help cover potential vitamin deficiencies.
- Prioritize Electrolytes: As with any ketogenic diet, maintaining electrolyte balance (sodium, potassium, magnesium) is crucial to avoid symptoms often called the "keto flu".
- Monitor Your Health: Pay attention to how your body responds. Track your energy levels, digestion, and any changes in your mood or well-being. Consult with a doctor or registered dietitian throughout the process.
Conclusion
The keto carnivore diet is a highly restrictive approach that combines the principles of ketosis with an animal-product-focused food list. While it offers potential benefits like weight loss, improved blood sugar control, and reduced inflammation, it also comes with risks, including nutrient deficiencies and digestive issues. The rules are centered on eating animal-based products, maintaining very low carbohydrate intake, and limiting or avoiding most plant foods. The success and safety of this diet depend heavily on individual health needs, careful planning, and, most importantly, medical supervision. The extreme nature of the diet makes long-term sustainability a challenge for many, highlighting the importance of considering a more balanced approach for lasting health.
