Understanding the Carnivore Diet
What is the Carnivore Diet?
The carnivore diet is an extremely restrictive eating pattern that consists entirely of animal-based products. This diet includes:
- Meat
- Poultry
- Eggs
- Seafood
- Fish
- Some dairy products
The carnivore diet eliminates all other foods, such as:
- Fruits
- Vegetables
- Grains
- Legumes
- Seeds
- Nuts
This makes the carnivore diet a “zero-carb” diet. By cutting out all plant-based foods, this diet stands apart from other restrictive diets (Harvard Health Publishing). Unlike most other diets, the carnivore diet is solely focused on animal products and is a type of ketogenic diet, leading the body to burn fat for energy and produce ketones.

Nutritional Composition of the Carnivore Diet
The nutritional composition of the carnivore diet is highly specific due to its limited food choices. It generally consists of high fat and protein intake while being extremely low in carbohydrates.
| Nutrient Distribution | Percentage of Daily Calories |
|---|---|
| Fat | 70% to 75% |
| Protein | 20% |
| Carbohydrates | Less than 10% |

Health Implications of the Carnivore Diet
Weight Loss on the Carnivore Diet
The carnivore diet is an ultra-restrictive regimen that consists solely of animal products, which includes meat, fish, eggs, and small amounts of low-lactose dairy. One of its touted benefits is weight loss.
According to Healthline, high-protein and low-carb diets, similar to the carnivore diet, can promote weight loss. Research shows that individuals consuming high-protein diets (0.4–0.6 grams of protein per pound of body weight per day) tend to lose more weight and fat mass than those on lower protein diets.
| Diet Type | Weight Loss | Fat Mass Loss |
|---|---|---|
| High-Protein | Higher | Higher |
| Low-Protein | Lower | Lower |

Research on the Carnivore Diet
Scientific Studies on the Carnivore Diet
The highly restrictive nature of the carnivore diet makes it challenging to follow long term. Moreover, the paucity of research supporting its alleged benefits raises concerns about its efficacy and safety for weight reduction and overall health improvement (Healthline).
One notable 2021 study analyzed the dietary intake of 2,029 individuals adhering to carnivore-style diets for nine to 20 months. Participants with type 2 diabetes experienced reductions in their levels of hemoglobin A1c (HbA1c) and a significant decrease in their diabetes medication use. Among the 262 participants with type 1 or type 2 diabetes, 84% discontinued oral diabetes medications and 92% of participants with type 2 diabetes stopped using insulin (Health.com).
Participant Experiences and Reported Benefits
Individuals who follow the carnivore diet often report high levels of satisfaction and perceived health benefits. These include improvements in overall health (95%), well-being (66%-91%), various medical conditions (48%-98%), and weight loss with a decrease in median BMI from 27.2 to 24.3 (PubMed Central).
Among participants with diabetes, those adhering to a carnivore diet experienced notable benefits such as reductions in median BMI, glycated hemoglobin (HbA1c), and diabetes medication usage.
| Variables | Median BMI Reduction | Glycated Hemoglobin Reduction (%) | Diabetes Medication Reduction (%) |
|---|---|---|---|
| Diabetic Participants | 4.3 | 0.4 | 84% to 100% |

Comparative Analysis
Carnivore vs. Keto Diet
When considering the carnivore diet for weight loss, it’s important to compare it with the well-known ketogenic (keto) diet. Both diets are low-carbohydrate, but they significantly differ in their approach and nutritional content.
-
Carbohydrate Intake: The carnivore diet consists exclusively of animal products, resulting in virtually zero carbohydrate intake. In contrast, the keto diet allows for a very low amount of carbohydrates, generally 5-10% of total caloric intake.
-
Protein and Fat Ratios: Both diets are high in protein and fat, but the carnivore diet has a higher protein ratio due to its focus on meat (Harvard Health Publishing). The keto diet balances protein intake to avoid interfering with ketosis.
-
Nutrient Diversity: The keto diet includes a variety of foods such as nuts, seeds, low-carb vegetables, and dairy, which provide essential vitamins and minerals. The carnivore diet lacks plant-based foods, raising concerns about deficiencies in vitamins C, K, folate, and fiber (Healthline).
-
Health Risks: The carnivore diet may lead to quick weight loss but carries significant health risks such as potential kidney stones, gout, and osteopenia due to its high protein intake (Harvard Health Publishing). On the other hand, the keto diet, though also restrictive, includes a broader spectrum of nutrients and has been studied more thoroughly for its long-term efficacy and safety.
| Comparison Factor | Carnivore Diet | Keto Diet |
|---|---|---|
| Carbohydrate Intake | Virtually zero | 5-10% of total caloric intake |
| Protein/Fat Ratios | Higher protein focus | Balanced to maintain ketosis |
| Nutrient Diversity | Limited to animal products | Includes nuts, seeds, low-carb vegetables |
| Health Risks | Kidney stones, gout, osteopenia | Possible keto flu, long-term sustainability |
| Long-Term Sustainability | Questionable | More sustainable with broader food options |
Long-Term Benefits and Sustainability
The sustainability and long-term benefits of the carnivore diet are topics of debate among nutrition experts.
-
Weight Loss and Maintenance: While the carnivore diet can induce rapid weight loss due to its low carb and high protein composition, maintaining this diet long-term is challenging. The severe restriction on food diversity makes it difficult to adhere to compared to the keto diet, which allows for a variety of foods and has shown effective for sustained weight loss.
-
Nutrient Deficiencies: The exclusion of plant-based foods in the carnivore diet can lead to deficiencies in essential vitamins and minerals, potentially resulting in long-term health issues such as scurvy (vitamin C deficiency), bone loss (due to lack of vitamin K), and reduced gut health due to a lack of dietary fiber.
-
Diet Suitability: Long-term keto dieting has been found to be more sustainable and better suited for a broader population. Keto diets, including the carnivore diet, can lead to initial weight loss by promoting fat burning (Harvard Health Publishing). However, keto includes a broader food list allowing flexibility (Healthline), making it more manageable for long-term adherence.
In conclusion, while both diets can induce weight loss, their sustainability and health impacts differ significantly. For individuals considering these diets, understanding these differences is crucial. For more on specific foods allowed, see our guide on what can you eat on the carnivore diet.
