What Is the Carnivore Diet?

The carnivore diet is pretty much what it sounds like—you eat animal products and nothing else. I've looked into this eating approach for years, and it's basically the ultimate elimination diet. You toss out all plants and stick to meat, fish, eggs, and sometimes dairy if you can handle it. Some folks call it the "zero-carb diet" or "animal-based diet" too.

This way of eating ain't exactly new. Many traditional societies like certain Inuit groups and some Mongolian tribes historically ate mostly animal foods, especially during winter months when plants weren't available. But the modern carnivore movement really took off around 2018 when several doctors and health influencers started sharing their positive experiences online.

The basic idea? Plants might not be as healthy as we've been told. Carnivore proponents argue that many plant foods contain natural defence chemicals (called antinutrients) that can cause inflammation and other problems in some people. By cutting them out completely, you might avoid these issues.

The Science Behind the Carnivore Diet

When you stop eating carbs, your body has to make some pretty big changes. After a few days with no carbohydrates coming in, your metabolism shifts gears. Your liver starts turning fat (both dietary and body fat) into ketones, which become your body's main fuel source instead of glucose. This metabolic state is called ketosis, and it's the same thing that happens on keto diets.

The carnivore diet works differently than most other diets for a simple reason—it's pure protein and fat with almost zero carbs. This forces your body to become super efficient at burning fat. Your insulin levels stay low all day long, which some researchers think helps with fat burning and reducing inflammation.

Another important thing that happens is your body might start a process called gluconeogenesis. This is just a fancy way of saying your liver makes glucose from protein when needed. Even though you're not eating carbs, certain body tissues still need some glucose, and your body is smart enough to make it.

What Can You Eat on a Carnivore Diet?

The carnivore diet is pretty straightforward when it comes to food choices, but there's still some variety. Here's what you can eat:

Core Foods (Eat Freely)

• All types of meat (beef, pork, lamb, poultry, game meats)

• Fish and seafood

• Eggs

• Animal fats (tallow, lard, duck fat)

• Salt and water

Optional Foods (Individual Tolerance)

• Dairy products (butter, heavy cream, hard cheeses)

• Bone broth

• Organ meats (liver, heart, kidneys)

Foods to Avoid Completely

• All vegetables and fruits

• Grains, legumes, nuts, and seeds

• Plant oils

• Sugar and artificial sweeteners

• All plant-based foods without exception

Most carnivore dieters find that fatty cuts of meat like ribeye steak and ground beef work better than lean options. This makes sense since fat becomes your primary energy source when you're not eating carbs.

Potential Benefits of the Carnivore Diet

People who stick with the carnivore diet often report some impressive benefits. I should mention that large clinical studies on this diet are still limited, but there's plenty of anecdotal evidence and some smaller studies supporting these potential advantages:

Weight Loss

One of the most common benefits is weight loss without calorie counting. The high protein content helps you feel full, while the shift to fat metabolism can help your body access stubborn fat stores. Many people find they naturally eat less when they only consume animal products.

Reduced Inflammation

Lots of folks with autoimmune conditions like rheumatoid arthritis, psoriasis, and inflammatory bowel disease report major improvements. By removing potentially inflammatory plant compounds, some people experience dramatic reductions in symptoms and pain levels.

Mental Clarity

Brain fog lifting is something I hear about constantly from carnivore dieters. The stable blood sugar and ketone production seem to provide consistent energy to the brain. Some people with anxiety, depression, and even more serious mental health conditions have reported improvements.

Digestive Health

For people who've struggled with IBS, bloating, and other digestive problems, the carnivore diet can sometimes provide relief. The elimination of fibre and plant antinutrients makes digestion simpler for some people.

Hormonal Balance

Some women report improvements in PCOS symptoms, while men sometimes see increased testosterone levels. The higher fat content of the diet supports hormone production, which requires cholesterol and saturated fat as building blocks.

Simplified Eating

There's something freeing about not having to think about what to eat. The carnivore diet eliminates decision fatigue around food choices. You're either eating animal products or you're not eating—simple as that.

Getting Started with the Carnivore Diet

If you're thinking about trying carnivore, I'd recommend taking a structured approach. Here's how to get started:

Step 1: Consult a Healthcare Provider

Before making any dramatic dietary change, talk to your doctor. This is specially important if you have existing health conditions or take medications. A comprehensive blood panel before starting gives you baseline measurements to track changes.

Step 2: Plan Your Transition

Some people do better with a gradual approach—first eliminating sugars and processed foods, then grains and starches, then remaining plant foods. Others prefer to jump in completely. Either approach can work, but be prepared for some adjustment symptoms.

Step 3: Stock Your Kitchen

Fill your fridge with plenty of animal-based foods you enjoy. Having easy options on hand makes sticking to the diet much easier. Consider buying meat in bulk to save money, since your meat consumption will increase significantly.

Step 4: Prepare for the Adaptation Period

The first few weeks can be challenging as your body adjusts. Common symptoms include:

• Fatigue and low energy

• Headaches

• Cravings for carbs

• Digestive changes

• Electrolyte imbalances

These symptoms, sometimes called "keto flu," usually pass within a few weeks as your metabolism adapts to using fat as fuel.

Step 5: Pay Attention to Electrolytes

Without carbs, your body retains less water and electrolytes. Adding salt to your food and maybe supplementing with magnesium can help prevent cramps and headaches during the transition.

Common Challenges and How to Overcome Them

The carnivore diet isn't always smooth sailing. Here are common challenges and how to deal with them:

Social Situations

Eating only meat at social gatherings can be awkward. I've found it helps to eat something before attending events, bring your own food when appropriate, or focus on the social aspect rather than the food.

Cost Concerns

Quality animal products can be expensive. To manage costs:

• Buy in bulk when possible

• Use a chest freezer for storage

• Explore less popular cuts of meat

• Include eggs as a more affordable protein

• Consider direct-from-farm purchasing

Variety and Food Boredom

Eating only animal products might seem limiting, but there are ways to keep it interesting:

• Experiment with different cooking methods (grilling, roasting, slow-cooking)

• Try different animal proteins (lamb, game meats, seafood)

• Include organ meats for nutritional variety

• Use different seasoning combinations with salt and spices

Nutritional Concerns

Some worry about nutrient deficiencies on a carnivore diet. While animal foods are incredibly nutrient-dense, consider:

• Eating nose-to-tail (including organs) for complete nutrition

• Getting regular bloodwork to monitor health markers

• Considering minimal supplementation if bloodwork indicates a need

Who Should Consider the Carnivore Diet?

The carnivore diet isn't for everyone, but certain groups might benefit more than others:

People with Autoimmune Conditions

Those suffering from conditions like rheumatoid arthritis, psoriasis, multiple sclerosis, or inflammatory bowel disease sometimes see significant improvements on a carnivore diet.

Individuals with Severe Food Sensitivities

If you've tried other elimination diets without success, carnivore represents the ultimate elimination approach to identify food triggers.

Those with Metabolic Issues

People with insulin resistance, metabolic syndrome, or who struggle with weight loss on other diets might respond well to the carnivore approach.

Mental Health Sufferers

Some people with anxiety, depression, or other mental health concerns report improvements on a carnivore diet, possibly due to the elimination of inflammatory foods and stabilized blood sugar.

People Who Prefer Dietary Simplicity

If you're tired of complicated meal plans and endless food rules, the straightforward nature of carnivore might appeal to you.

That said, this diet isn't recommended for:

• Pregnant or breastfeeding women (without medical supervision)

• People with certain liver or kidney conditions

• Those with a history of eating disorders

• Children and teenagers (without medical supervision)

Frequently Asked Questions

Is the carnivore diet safe long-term?

We don't have long-term studies on the modern carnivore diet, though historical populations have thrived on near-carnivore diets. Regular medical monitoring is recommended if you plan to follow this diet indefinitely.

Will I get scurvy without vitamin C from fruits and vegetables?

Fresh meat, especially organ meats, contains small amounts of vitamin C, and your body's requirement for vitamin C decreases on a low-carb diet. Historical carnivorous populations didn't develop scurvy. That said, if concerned, organ meats like liver contain vitamin C.

What about fibre and gut health?

The conventional wisdom about needing fibre for gut health is being questioned. Many carnivore dieters report improved digestion without fibre, suggesting that some people might do better without it. Your gut microbiome will change on a carnivore diet, but different doesn't necessarily mean unhealthy.

How does the carnivore diet affect cholesterol levels?

Results vary. Some people see improvements in their lipid profiles, while others experience elevated LDL cholesterol. The traditional cholesterol model may not apply the same way when carbohydrates are eliminated. Regular monitoring and discussing results with a knowledgeable healthcare provider is recommended.

Can I exercise effectively on the carnivore diet?

Yes, though there may be an adaptation period. Many athletes, including strength trainers and endurance athletes, report good performance once fully adapted to fat-burning. Your body becomes more efficient at using stored fat for energy over time.

Is this just another fad diet?

While the modern carnivore movement is relatively new, eating primarily animal foods is not new to human history. Whether it proves to be a lasting dietary approach or not, many people are finding significant health benefits from this way of eating.

Do I need to eat organ meats on the carnivore diet?

While not strictly required, organ meats provide important nutrients that might be harder to get from muscle meat alone. Incorporating items like liver once a week can help ensure more complete nutrition.

Can I drink coffee or tea on the carnivore diet?

Strict carnivore dieters avoid all plant products, including coffee and tea. However, many people follow a "carnivore-ish" approach that includes these beverages. It depends on your goals and individual tolerance.
