Understanding the Modified Carnivore Approach
The carnivore diet mixed with vegetables, commonly referred to as the 'ketovore' diet, is a hybrid approach that combines the principles of both the carnivore and ketogenic diets. While the traditional carnivore diet is zero-carb, consisting solely of animal products like meat, fish, and eggs, the ketovore modification permits small amounts of low-carb, nutrient-dense plant foods. This variation was made popular by figures like psychologist Jordan Peterson, who followed a "meat and greens" version consisting of beef, salt, water, and cooked greens. The inclusion of vegetables aims to address some of the main criticisms of the strict carnivore diet, such as the potential for nutrient deficiencies and lack of fiber.
Why Add Vegetables to a Carnivore Diet?
Followers of a modified carnivore diet cite several reasons for incorporating vegetables:
- Increased Fiber Intake: The complete absence of fiber in a strict carnivore diet can lead to digestive issues like constipation. Adding low-carb vegetables helps promote digestive regularity and supports gut health.
- Expanded Nutrient Profile: While animal products are nutrient-dense, certain micronutrients, such as vitamin C, magnesium, and specific antioxidants, are found predominantly in plants. A modified diet can fill these potential nutritional gaps.
- Enhanced Flavor and Variety: For many, the extreme restriction of a pure carnivore diet is difficult to sustain long-term. The addition of vegetables provides a wider range of flavors, colors, and textures, making meals more enjoyable.
- Reduced Oxalate Load: Some plant foods, particularly certain leafy greens, contain compounds called oxalates, which can be problematic for sensitive individuals. However, by being selective and cooking vegetables, some find they can tolerate them without issues. Some proponents even use it as a tool to mitigate potential issues from oxalate dumping that can happen after prolonged periods of zero-plant diets.
The Ketovore Diet: A Closer Look
Unlike a standard keto diet, which allows a wider range of high-fat, low-carb foods, the ketovore diet maintains a strong focus on animal-based nutrition. The majority of calories still come from fatty animal meats, fish, and animal fats. The plant portion is supplementary and strictly limited to low-carb options to keep the body in a state of ketosis.
Commonly Allowed Vegetables on a Ketovore Diet:
- Leafy Greens: Spinach, kale, Swiss chard, and lettuce are often included for their nutrient content and minimal carbohydrate impact.
- Cruciferous Vegetables: Broccoli, cauliflower, and cabbage are popular choices due to their low-carb profile.
- Mushrooms: A versatile addition that is low in calories and carbs.
- Other Low-Carb Options: Zucchini, asparagus, and bell peppers are also frequently used.
Ketovore vs. Carnivore: A Comparative Analysis
| Feature | Carnivore Diet (Strict) | Ketovore Diet (Modified) |
|---|---|---|
| Allowed Foods | Meat, fish, eggs, some dairy, water. NO plants. | Primarily animal products, plus small amounts of low-carb vegetables, herbs, and spices. |
| Carbohydrate Content | Virtually zero carbohydrates. | Very low carbohydrate, typically under 20-50 grams per day. |
| Dietary Fiber | None. Eliminates all plant-based fiber sources. | Minimal to moderate intake, derived from low-carb vegetables. |
| Sustainability | Highly restrictive and often challenging to maintain long-term due to limited variety. | Considered more flexible and potentially easier to sustain due to added variety. |
| Potential Nutrient Gaps | Risk of deficiencies in vitamin C, magnesium, and fiber over time. | Reduced risk of certain nutrient deficiencies due to plant inclusion. |
Potential Benefits and Considerations
Proponents of the ketovore diet suggest it allows for a balance of benefits from both carnivore and keto approaches. It offers the reduced inflammatory potential and blood sugar control of a high-fat, low-carb diet while mitigating some of the restrictive nature of a strict all-meat regimen. The addition of vegetables can help with digestion and provide antioxidants not found in animal products alone.
However, this modified approach is not without its considerations. While some find relief from plant sensitivities on a strict carnivore diet, adding vegetables back may reintroduce potential irritants for some individuals. Additionally, the long-term health effects of any highly restrictive diet, including modified versions, require more robust clinical research for definitive conclusions. As with any significant dietary change, it is advisable to consult with a healthcare provider.
Conclusion
The carnivore diet mixed with vegetables, or the 'ketovore' diet, is a dietary modification that allows for greater flexibility and nutrient variety than a traditional carnivore approach. By incorporating select low-carb plant foods, followers can gain access to additional fiber and micronutrients, potentially making the diet more sustainable over time. This hybrid model serves as a middle ground for individuals seeking the benefits of an animal-focused diet while still desiring the inclusion of some plant-based foods. While anecdotal evidence suggests positive outcomes for some, potential drawbacks and long-term health impacts are still being explored. Understanding the distinctions between the strict and modified versions is crucial for anyone considering this eating style.
