Is the Carnivore Diet Safe? Everything You Need to Know

Diet trends come and go, but one that has gained considerable attention in recent years is the carnivore diet. Touted by some as the ultimate way to achieve optimal health while criticized by others for its restrictive nature, this diet has sparked heated debates among nutritionists, doctors, and fitness enthusiasts alike. But what exactly is the carnivore diet, and is it as beneficial—or harmful—as some claim? Let’s take a closer look.

What is the Carnivore Diet?

The carnivore diet is an extreme version of low-carb eating, where individuals consume only animal-based foods. This includes:

• Meat (beef, pork, lamb, chicken, turkey, etc.)
• Fish and seafood
• Eggs
• Animal fats (butter, tallow, lard)
• Dairy (optional, depending on tolerance)

This diet completely eliminates all plant-based foods, including vegetables, fruits, grains, legumes, nuts, and seeds. Essentially, if it didn’t come from an animal, it’s not on the menu.

Origins of the Carnivore Diet

While the carnivore diet seems extreme in modern society, its proponents argue that humans evolved as hyper-carnivorous species, relying heavily on animal-based foods for survival. Advocates often reference indigenous groups such as the Inuit, who have historically thrived on a diet consisting almost entirely of animal products.

The modern resurgence of the carnivore diet has been largely popularized by figures like Dr. Shawn Baker, a former orthopedic surgeon, and Mikhaila Peterson, who credits the diet with helping her overcome autoimmune disorders.

Merits of the Carnivore Diet

1. Potential for Weight Loss

The carnivore diet is inherently low in carbohydrates, which can help promote fat loss by reducing insulin spikes and encouraging the body to burn stored fat for energy. High protein intake also boosts satiety, leading to reduced cravings and lower calorie consumption overall.

2. May Reduce Inflammation

Many people following the carnivore diet report reductions in chronic inflammation. Since it eliminates processed foods, sugars, and seed oils—all of which are linked to inflammation—the diet may help alleviate conditions like arthritis, autoimmune diseases, and joint pain.

3. Blood Sugar Regulation

For individuals with type 2 diabetes or insulin resistance, eliminating carbohydrates may result in improved blood sugar control. Several anecdotal reports suggest that following a zero-carb diet can stabilize blood glucose levels and even reduce the need for medication.

4. Simple and Easy to Follow

Unlike complex diets that require calorie counting, macro tracking, or meal planning, the carnivore diet is straightforward: eat meat, drink water. This simplicity makes it easier for some people to adhere to, eliminating the decision fatigue associated with meal planning.

5. High in Nutrient-Dense Foods

Animal products are rich in essential nutrients, including:

• Protein (muscle repair and growth)
• B vitamins (energy production)
• Iron (oxygen transport in the blood)
• Zinc (immune function)
• Omega-3 fatty acids (brain and heart health)

In theory, a well-structured carnivore diet could provide most essential nutrients without supplementation.

Demerits of the Carnivore Diet

1. Nutrient Deficiencies

While animal foods contain many essential nutrients, the lack of plant-based foods means followers miss out on key vitamins, including:

• Vitamin C (important for immune health and collagen synthesis)
• Fiber (essential for gut health)
• Antioxidants and phytonutrients (which help combat oxidative stress)

Over time, deficiencies in these nutrients could pose significant health risks.

2. Gut Health Concerns

Fiber plays a crucial role in feeding beneficial gut bacteria, which help with digestion, immune function, and mental health. Without fiber, there is concern that gut microbiome diversity may decline, potentially leading to digestive discomfort, constipation, and other gastrointestinal issues.

3. Increased Risk of Heart Disease?

Since the carnivore diet is high in saturated fat and cholesterol, critics argue that it may increase the risk of heart disease. However, recent research suggests that saturated fat may not be as harmful as once believed, and its impact varies based on an individual’s metabolic health. More long-term studies are needed to fully understand the relationship between the carnivore diet and heart disease.

4. Possible Kidney Strain

High protein intake can increase the workload on the kidneys, particularly for individuals with pre-existing kidney disease. While healthy individuals can generally handle a high-protein diet, those with compromised kidney function should exercise caution.

5. Social and Practical Challenges

• Dining out becomes difficult since most meals contain plant-based foods.
• Grocery shopping is expensive, as high-quality meats and seafood can be costly.
• Food variety is limited, leading to potential boredom and difficulty maintaining the diet long-term.

Is the Carnivore Diet Recommended?

The carnivore diet remains controversial due to the lack of extensive, long-term scientific studies. However, it may be beneficial in the short term for specific populations, such as:

• Individuals with autoimmune conditions (some find relief from symptoms when eliminating plant foods)
• People struggling with obesity or type 2 diabetes (due to blood sugar stabilization and weight loss effects)
• Those with severe food sensitivities (it serves as an elimination diet to pinpoint triggers)

That said, long-term adherence carries potential risks. Most health professionals recommend a balanced diet that includes a variety of nutrient-dense foods, rather than restricting to only one food group.

Final Verdict on the Carnivore Diet

The carnivore diet is a highly restrictive eating plan that prioritizes animal foods while eliminating all plant-based foods. While it may offer weight loss benefits, reduced inflammation, and improved blood sugar control, it also raises concerns about nutrient deficiencies, gut health, and long-term sustainability.

If you’re considering the carnivore diet, it’s essential to consult a healthcare professional, particularly if you have underlying health conditions. While it might work well as a short-term intervention or elimination diet, a more balanced approach—incorporating a mix of animal and plant-based foods—is likely a safer, more sustainable choice for long-term health.
