The carnivore diet, a highly restrictive eating plan, involves consuming only meat and other animal products. This article explores the carnivore diet, including its potential benefits, risks, and a closer look at the role of spices within this dietary framework.
What is the Carnivore Diet?
The carnivore diet eliminates all carbohydrates, focusing solely on animal products like beef, chicken, pork, fish, and eggs. The core principle is that by cutting out carbs, the body shifts to burning fat for energy, leading to weight loss. Proponents also claim it can reduce inflammation, improve blood sugar control in individuals with diabetes, and enhance mental well-being.
This diet shares similarities with the ketogenic (keto) and Atkins diets, but with a key difference. While keto and Atkins diets limit carbohydrates, the carnivore diet completely excludes them, along with other food groups like fruits, vegetables, grains, nuts, seeds, and legumes.
The concept of a carb-free diet isn't entirely new. In the late 1700s, Scottish military surgeon Dr. John Rollo used a meat-only diet to manage diabetes in his patients, successfully lowering their blood sugar levels. More recently, former orthopedic surgeon Dr. Shawn Baker popularized the carnivore diet with his 2019 book, "The Carnivore Diet." Comedian and podcast host Joe Rogan's endorsement further boosted the diet's popularity.
How it Works
Carbohydrates are the body's primary energy source. When consumed, they are converted into glucose (sugar) for immediate use or stored in muscles and the liver. Excess glucose is then converted to fat.

In the absence of carbohydrates, the body turns to fat for energy, producing ketones. Advocates of the carnivore diet claim this process accelerates fat burning and weight loss while suppressing hunger. They also suggest it improves blood sugar control in individuals with type 2 diabetes and reduces inflammation by eliminating inflammatory foods.
Allowed Foods
The carnivore diet restricts food choices to animal-based products.
Foods Allowed:
- Red meat: Steak, burgers, chuck roast
- Poultry: Chicken, lamb, pork
- Seafood: Salmon, trout, oysters, clams
- Organ meats: Liver, oxtail
- Eggs (in small amounts)
- Cooking fats: Butter, tallow, ghee
Foods to Avoid:
Any foods that aren’t animal-based are off the table. You can’t eat fruits, vegetables, grains, legumes, nuts, or seeds.
- Fruits
- Vegetables
- Grains
- Legumes
- Nuts
- Seeds
Foods to Eat in Limited Amounts:
- Cheese
- Other dairy foods like milk and yogurt
- Bacon
- Sausage
- Cured meats
Spices on the Carnivore Diet
One of the primary reasons people experience success on the carnivore diet is the elimination of inflammatory plant-based foods. In a diet centered around meat and animal products, the use of herbs and spices is generally accepted, given that they are consumed in trace amounts. However, even these small quantities can trigger symptoms in some individuals, depending on the specific spices used.
Antinutrients
Potential issues arising from certain spices are linked to antinutrients, which are plant compounds capable of binding to minerals and causing other problems within the body, such as kidney stones, leaky gut, and autoimmune conditions. When selecting herbs and spices for the carnivore diet, prioritize those with low antinutrient content.

Potential Benefits
The carnivore diet is promoted as a weight loss strategy, with additional claims of improving heart health, autoimmune issues, blood sugar control, and mood. However, these claims are primarily based on anecdotal evidence rather than rigorous scientific research.
A survey of over 2,000 individuals who had followed the carnivore diet for 9 to 20 months reported improvements such as:
- Lower body mass index (BMI)
- Increased energy levels
- Improved sleep quality
- Enhanced strength and endurance
- Better memory and focus
Many participants with diabetes reported being able to reduce or eliminate their diabetes medication. However, this study relied on self-reported data, without objective measurements of nutrient levels or health status. The authors emphasized the need for further research to gain a comprehensive understanding of the carnivore diet.

Potential Risks and Side Effects
The carnivore diet contradicts the Dietary Guidelines for Americans, which recommend obtaining 45% to 65% of daily calories from carbohydrates. Excluding entire food groups can lead to deficiencies in essential vitamins and minerals. For instance, vegetables provide fiber, potassium, vitamins A and C, and folate. Insufficient fiber intake can cause constipation, although some individuals on the carnivore diet have reported diarrhea instead.
A high-fat, high-protein diet can disrupt the balance of gut bacteria, potentially leading to loose stools. Other reported side effects include headaches, nausea, and fatigue. Animal-based diets are typically high in saturated fat, which can elevate unhealthy LDL cholesterol levels, increasing the risk of heart disease and stroke. Processed meats, often included in the diet, are high in salt, potentially raising blood pressure.
Is the Carnivore Diet Sustainable?
Registered dietitian nutritionist Kathleen Zelman, MPH, emphasizes that while the carnivore diet may lead to weight loss, it also carries the risk of nutrient deficiencies and is not a sustainable long-term solution. The restrictive nature of the diet makes it difficult to maintain, and food cravings are likely to emerge over time.
Does the Carnivore Diet Work for Weight Loss?
While low-carbohydrate diets like the keto diet have demonstrated short-term weight loss benefits, the long-term effectiveness of the carnivore diet is uncertain due to a lack of research. The initial weight loss may be attributed to the elimination of calorie-dense, processed foods and the satiating effect of high protein and fat intake. However, the restrictive nature of the diet makes it challenging to adhere to long-term, and any weight loss may be regained upon returning to previous eating habits.
Is the Carnivore Diet Safe?
The carnivore diet is generally not recommended by dietitians or health professionals due to its restrictive nature and potential for nutrient deficiencies. The Dietary Guidelines for Americans and the American Heart Association advocate for a balanced diet that includes plant-based foods, which provide essential nutrients, phytochemicals, fiber, antioxidants, vitamins, minerals, and micronutrients not found in animal products.
Who Should Avoid the Carnivore Diet?
The carnivore diet is not suitable for pregnant or breastfeeding women due to the risk of nutrient deficiencies that could harm both mother and child. Individuals with kidney disease may experience difficulties processing the high protein content. The diet is also not recommended for those with diabetes, heart disease, or high blood pressure due to its high saturated fat and sodium content. Furthermore, individuals with a history of eating disorders should avoid such restrictive diets, as they can trigger unhealthy eating patterns.
