Low-carb diets, particularly keto and carnivore, have recently gained significant attention, especially among individuals planning to achieve their weight goals. Although both diets focus on reducing carbohydrate intake, they approach this goal differently. This article explores the advantages and disadvantages of each diet and provides a well-researched comparison of their suitability for your dietary needs.

The Keto Diet: What Is It?
The ketogenic diet, often referred to as the keto diet, is an eating plan that is high in fat, moderate in protein, and low in carbohydrates. This diet aims to shift the body’s metabolism into a state known as ketosis. In ketosis, the body prioritizes fat as its primary source of fuel instead of carbohydrates. It breaks down fat into small molecules called ketones, which are then used for energy.
The keto diet allows for a variety of foods, as long as excessive carbohydrates are avoided. It mainly encourages the consumption of foods such as avocados, nuts, meats, and cheese. The amount of carbohydrate intake can vary from person to person, but it is generally advised to consume the lowest amount of carbs possible.
The Carnivore Diet: What Is It?
The carnivore diet is an all-animal product diet that eliminates all plant-based foods. It focuses exclusively on consuming meat, fish, eggs, and certain dairy products. Some people refer to the carnivore diet as a “keto carnivore” diet because of its extremely low carbohydrate content. However, it may not always lead to ketosis, depending on the balance of protein and fat. This diet not only excludes carbohydrate-containing foods but also eliminates berries, vegetables, nuts, and seeds.
The belief that humans should avoid all plant foods comes from the controversial idea that our ancestors mainly consumed animal products. Some proponents suggest avoiding plant foods may help individuals with specific sensitivities or autoimmune issues, citing compounds like lectins or oxalates. However, scientific support for widespread harm from plant compounds is limited, and most nutrition experts recognize the health benefits of plant-based foods. While some claim the diet aids in weight loss and overall health, limited research on its long-term effects suggests it may pose serious risks.
Key Differences Between the Keto Diet and the Carnivore Diet
| Comparison Criteria | Keto Diet | Carnivore Diet |
| Carbohydrate Intake | Low | Extremely low/ Negligible |
| Food Intake | Includes both animal and plant-based foods | Exclusively animal-based foods |
| Fiber Intake | Present (from vegetables and fruits) | Absent |
| Micronutrient Source | Diverse (from both animal and plant sources) | Limited ( mainly from animal sources) |
| Diet Flexibility | Moderate | Restricted |
Pros and Cons of Both Diets
Keto Diet:
| Pros | Cons |
| Supports weight goals and fat burning | Requires careful tracking of macronutrients |
| Supports weight goals and fat burning | Adaptation to the keto diet might cause inconvenience. |
| Offers a variety of food choices, making it sustainable | Potential for nutrient deficiency if not planned carefully |
Carnivore Diet:
| Pros | Cons |
| Simplifies meal planning | Lacks dietary fiber, which may affect gut health |
| Removes many potential dietary irritants for sensitive individuals | The diet is highly restrictive and excludes many macronutrients that are typically obtained from plants. |

Making the Right Choice: Keto or Carnivore
Deciding between the keto and carnivore diets largely depends on your health objectives, dietary preferences, and how your body reacts to changes in nutrition. The keto diet provides a greater variety of food options and is backed by a wider range of scientific research, making it a good choice for many people looking for a sustainable low-carb approach. On the other hand, the carnivore diet is more restrictive and might be advantageous for individuals who want to follow an elimination diet to identify food allergies.
Frequently Asked Questions
Which is healthier, Keto or Carnivore?
Current nutrition science suggests that the keto diet, with its broader nutrient base and fiber content, may be more balanced for long-term use. The carnivore diet can help with certain conditions, but it lacks fiber and some micronutrients. The keto diet offers more variety and a better long-term nutrient profile for most people.
Does a carnivore diet put you in Ketosis?
Yes, a carnivore diet can put you through ketosis. However, keto puts you through ketosis through calculated macros, but carnivore induces ketosis by default through carb elimination.
Can you build muscles in keto or carnivore?
Yes, you can build muscle on both diets with adequate protein and strength training. Carnivore provides more complete animal proteins, while keto requires more planning to balance fats and proteins for muscle growth.
Is the carnivore diet safe long-term?
Long-term safety is still under scientific review. While some people report great results, others may experience nutrient imbalances or digestive issues. Regular lab monitoring and professional guidance are advised.
Can I mix both diets?
Yes, many people follow a hybrid approach, sticking to carnivore on certain days and incorporating keto-friendly plant foods on others. While anecdotal reports suggest this may support sustainability and variety, there is little formal research on hybrid low-carb strategies.
