Keto vs the Carnivore Diet: Which is the Better Option?

When it comes to dieting, there are countless options available, each claiming to be the best for weight loss, improved health, and increased energy levels. Two popular diets that have gained significant attention in recent years are the ketogenic diet (keto) and the carnivore diet. Both diets have their own unique approaches to nutrition and have been praised for their potential benefits. In this article, we will explore the key differences between keto and the carnivore diet, and delve into the scientific evidence behind each to determine which one may be the better option for you.

The Ketogenic Diet (Keto)

The ketogenic diet is a low-carbohydrate, high-fat diet that has been used for decades to treat epilepsy in children. It involves drastically reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis. In ketosis, the body becomes efficient at burning fat for energy instead of carbohydrates.

Key features of the ketogenic diet include:

  • Carbohydrate intake typically limited to 20-50 grams per day
  • High consumption of healthy fats, such as avocados, nuts, and olive oil
  • Moderate protein intake
  • Focus on whole, unprocessed foods

Benefits of the ketogenic diet:

  • Weight loss: The ketogenic diet has been shown to be effective for weight loss due to its ability to suppress appetite and increase fat burning.
  • Improved blood sugar control: By reducing carbohydrate intake, the ketogenic diet can help stabilize blood sugar levels and improve insulin sensitivity.
  • Increased energy levels: Many individuals report increased energy and mental clarity when following a ketogenic diet.

The Carnivore Diet

The carnivore diet, as the name suggests, is a diet that consists solely of animal products. It eliminates all plant-based foods, including fruits, vegetables, grains, and legumes. Advocates of the carnivore diet believe that humans are best adapted to consuming animal products and that plant foods are unnecessary and potentially harmful.

Key features of the carnivore diet include:

  • Exclusive consumption of animal products, such as meat, fish, eggs, and dairy
  • No intake of carbohydrates or plant-based foods
  • Emphasis on high-quality, nutrient-dense animal products

Potential benefits of the carnivore diet:

  • Weight loss: By eliminating carbohydrates and focusing on protein and fat, the carnivore diet may lead to weight loss.
  • Reduced inflammation: Some individuals report a reduction in inflammation and autoimmune symptoms when following the carnivore diet.
  • Simplicity: The carnivore diet is straightforward and eliminates the need for complex meal planning and food choices.

Scientific Evidence and Considerations

While both the ketogenic diet and the carnivore diet have their proponents, it is important to consider the scientific evidence and potential drawbacks of each.

Ketogenic Diet:

Scientific studies have shown that the ketogenic diet can be effective for weight loss and improving certain health markers. However, it is important to note that the long-term effects of the diet are still not well understood, and there may be potential risks and side effects, such as:

  • Keto flu: Some individuals experience flu-like symptoms, such as fatigue and headaches, when transitioning into ketosis.
  • Nutrient deficiencies: Restricting carbohydrate intake can make it challenging to obtain certain essential nutrients, such as fiber, vitamins, and minerals.
  • Difficulty in adherence: The strict nature of the ketogenic diet can make it difficult for some individuals to sustain in the long term.

Carnivore Diet:

While there is limited scientific research specifically on the carnivore diet, anecdotal evidence suggests that some individuals may experience benefits. However, it is important to consider the potential drawbacks and risks associated with this diet:

  • Nutrient deficiencies: By eliminating plant-based foods, the carnivore diet may lead to deficiencies in certain vitamins, minerals, and fiber.
  • Long-term sustainability: The restrictive nature of the carnivore diet may make it challenging to maintain in the long term.
  • Potential health risks: The long-term health effects of consuming a diet exclusively based on animal products are still not well understood.


Both the ketogenic diet and the carnivore diet have their own unique approaches to nutrition and potential benefits. While the ketogenic diet has been more extensively studied and has a larger body of scientific evidence supporting its use, the carnivore diet remains a controversial and less researched option. It is important to consider individual preferences, health goals, and consult with a healthcare professional before making any significant dietary changes. Ultimately, the best diet for an individual may vary depending on their specific needs and circumstances.
