The carnivore diet, a restrictive dietary approach, involves consuming exclusively meat and other animal products such as beef, chicken, pork, fish, and eggs. This diet aims to shift the body's primary energy source from carbohydrates to fat, potentially leading to weight loss. Proponents also suggest it may reduce inflammation, improve blood sugar control in individuals with diabetes, and enhance mental well-being.
Understanding the Carnivore Diet
The carnivore diet shares similarities with the ketogenic (keto) and Atkins diets but differs in its stringency. While keto and Atkins diets limit carbohydrate intake, the carnivore diet eliminates all carbohydrates and other food groups, including fruits, vegetables, grains, nuts, seeds, and legumes.
Historical Context
The concept of a carb-free diet dates back to the late 1700s when Scottish military surgeon John Rollo, MD, employed a meat-only diet to manage diabetes in his patients. This approach effectively lowered their blood sugar levels. In more recent times, former orthopedic surgeon Shawn Baker, MD, popularized the carnivore diet with his 2019 book, "The Carnivore Diet." Comedian and podcast host Joe Rogan further amplified the diet's visibility after reporting weight loss and increased energy levels during a 30-day meat-only experiment in 2019.
Dietary Guidelines and Considerations
The carnivore diet stands in contrast to the Dietary Guidelines for Americans, which emphasize the consumption of fruits, vegetables, whole grains, and lean protein from animal sources. Eliminating entire food groups may result in nutrient deficiencies, potentially compromising overall health.
How the Body Responds to Carbohydrate Restriction
Carbohydrates serve as the body's primary energy source. When consumed, they are converted into glucose, which is then used for energy or stored in muscles and the liver. Excess glucose is converted to fat. In the absence of carbohydrates, the body relies on fat for energy, producing ketones as an alternative fuel source.

Claims and Counterclaims
Advocates of the carnivore diet assert that eliminating carbohydrates accelerates fat burning and weight loss while reducing hunger. They also suggest that it improves blood sugar control in individuals with type 2 diabetes and reduces inflammation by excluding inflammatory foods. However, it's crucial to acknowledge that individual responses to dietary plans vary. Claims surrounding the carnivore diet lack substantiation from WebMD, and consulting a healthcare professional before initiating such a restrictive diet is advisable.
Getting Started with the Carnivore Diet
Embarking on the carnivore diet requires minimal preparation beyond grocery shopping. Clearing the pantry and refrigerator of carbohydrate-containing foods can help mitigate temptation. The shopping list primarily consists of items from the meat, poultry, and seafood sections of the grocery store.
Approved Food List
The carnivore diet restricts food choices to animal products. Acceptable options include:
- 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, fat tallow, or ghee
Seasonings like salt, pepper, chili paste, cumin, paprika, and garlic are permitted to add flavor.
Foods to Avoid
Any foods not derived from animals are prohibited, including fruits, vegetables, grains, legumes, nuts, and seeds.

Dairy Consumption
While cheese and other dairy products like milk and yogurt are allowed, moderation is advised due to their potential inflammatory effects.
Detailed Food List
A comprehensive list of foods suitable for the carnivore diet includes:
- Beef: Brisket, chuck roast, ground beef, steaks (New York strip, ribeye, skirt, porterhouse, T-bone)
- Chicken and pork: Chicken breast, thighs, drumsticks, wings, rotisserie chicken, pork butt, pork chops, bacon, pork ribs, pork shoulder
- Lamb: Lamb chops, lamb shanks, ground lamb
- Seafood: Fish (salmon, trout, mackerel), clams, crabs, mussels, oysters, scallops, shrimp, lobster
- Organ meats: Liver, kidneys, tongue, oxtail, heart, feet, cheeks
Foods to consume in limited quantities include cheese, eggs, heavy cream, milk, yogurt, bacon, sausage, and cured meats.
Pros and Cons of the Carnivore Diet
The carnivore diet, like any dietary approach, presents both potential benefits and drawbacks. Considering individual lifestyles and preferences is essential when choosing a diet.
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 medical research.

Limited research exists on the carnivore diet. One survey of over 2,000 individuals who had followed the diet for nine to 20 months reported improvements in body mass index (BMI), energy levels, sleep quality, strength and endurance, and cognitive function. Many participants with diabetes were able to reduce or eliminate their diabetes medication. However, this study relied on self-reported data and lacked objective measurements of nutrient levels and overall health.
Potential Side Effects
The carnivore diet contradicts the Dietary Guidelines for Americans, which recommend that adults obtain 45% to 65% of their daily calories from carbohydrates. Eliminating entire food groups may lead to deficiencies in essential vitamins and minerals. For example, 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.
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 LDL cholesterol levels, increasing the risk of heart disease and stroke. Processed meats, often included in the diet, are high in sodium, which can raise blood pressure.
Expert Opinions
While the carnivore diet may facilitate weight loss, it also carries the risk of nutrient deficiencies and may not be sustainable long-term. The restrictive nature of the diet can lead to food cravings and a desire for a more varied diet.
Regarding claims of reduced inflammation and increased energy, there is currently no scientific evidence to support these assertions. Carbohydrates are essential for fueling the brain and maintaining stable blood sugar levels, and their absence may result in decreased energy levels.
Safety Considerations
While short-term adherence to the carnivore diet may not be harmful for healthy individuals, it is generally not recommended. Dietitians and health professionals typically advise against such a restrictive eating plan due to its limited fiber content and potential for nutritional deficiencies. The Dietary Guidelines for Americans and the American Heart Association advocate for the consumption of plant-based foods due to their abundance of nutrients, phytochemicals, fiber, antioxidants, vitamins, minerals, and micronutrients.
Alternatives
For individuals seeking to reduce carbohydrate intake for weight loss, the keto and Paleo diets offer slightly more flexible options, allowing for limited carbohydrate consumption.
Contraindications
The carnivore diet is not suitable for pregnant or breastfeeding women due to its potential to cause nutrient deficiencies that could harm both the mother and the developing baby. Individuals with kidney disease should also avoid this diet due to the high protein content, which can strain the kidneys. Furthermore, those with diabetes, heart disease, or high blood pressure should exercise caution due to the high saturated fat and sodium content. Individuals with a history of eating disorders should avoid restrictive diets like the carnivore diet, as they can trigger unhealthy eating patterns.

Bacon Considerations for the Carnivore Diet
While bacon is technically meat, it is important to consider its processed nature and potential additives when incorporating it into the carnivore diet.
Choosing the Right Bacon
The best bacon for the carnivore diet is simple, clean, and fatty, without any added sugar, seed oils, or filler. Avoid bacon with ingredients like cane sugar, brown sugar, maple syrup, sunflower oil, soybean oil, canola oil, sodium erythorbate, and artificial smoke flavoring.
Cured vs Uncured Bacon
"Uncured" bacon is still cured, but it is important to focus on the ingredient list to avoid unwanted additives. Opt for thick-cut, dry-cured options with fewer additives from a reputable butcher.
Ways to Incorporate Bacon into the Carnivore Diet
- Fry chopped bacon in beef tallow until crispy.
- Use bacon to mask the flavor of organ meats like liver.
- Create bacon "chips" by baking bacon until crispy and brittle.
- Add bacon to bone broth with raw eggs for a carnivore-friendly soup.
- Wrap shrimp or scallops in bacon and cook.
