The keto carnivore diet is exactly what it sounds like– a combination of ketogenic macronutrient ratios with a carnivore eating plan.
This means eating only animal products while getting at least 70% of your calories from animal fats.
A keto carnivore way of eating resets the gut microbiome, supplies your body with highly bioavailable nutrients, and reduces inflammation by eliminating plant toxins and antinutrients, excess carbs, and toxic seed “vegetable” oils.
Let’s dig into the keto carnivore diet by exploring what it is, its benefits, and how to do it safely and sustainably.
Keto carnivore combines high-fat, low-carb, moderate protein macro ratios with an all-meat or all-animal product diet.
Standard ketogenic macro percentages call for
A standard keto diet is generally high in animal meats and fats, and low in plant foods, though it allows for some low-carb fruits and veggies. This is because animal products are naturally very low in carbs while providing an abundance of healthy protein and fats. Fruits and veggies, on the other hand, are generally low in fat and high in carbs.
The carnivore keto diet takes this standard keto macronutrient (fat, protein, carbs) ratios and applies carnivore diet rules calling for only animal products while eliminating all plant foods.
Research suggests that keto carnivore is the evolutionarily aligned version of both keto and carnivore.
Eliminating all plant foods and eating mostly animal fat may sound extreme in the context of a high-carb Standard American Diet.
However, researchers like Miki Ben-Dor and Amber O’Hearn make a strong case that keto carnivore is the way our caveman ancestors ate, and therefore evolved on, for nearly two million years.

Here are a few of the key points supporting the view that humans are keto carnivores by nature.
The irony of the keto carnivore diet is that if you have a properly formulated carnivore diet meal plan, you are, by default, practicing a keto carnivore diet.
Getting more than 50% of your calories from protein causes protein poisoning. Symptoms include hyperinsulinemia, nausea, diarrhea, and in extreme, prolonged cases, death. [3]

Arctic explorer Vilhjalmur Stefansson was one of the first Westerners to try and then champion the keto carnivore diet.
Back in the early 1900s, Stefansson lived with the Inuit in the Arctic where he learned to thrive on a carnivore diet of mostly animal fats.
To demonstrate the benefits of this diet to an incredulous grain-based Western world, he and a friend ate only meat for an entire year under observation at New York’s Bellevue Hospital.
Both men thrived until the researchers had them eat only lean meat. Stefansson describes this shortage of fat as causing “diarrhea and a feeling of general baffling discomfort.”
The good news is that both men quickly reversed these symptoms with a single high-fat meal of brains fried in bacon fat along with sirloin steak.
After this episode of temporary protein poisoning, the observers determined that the ideal carnivore diet macronutrient ratio was 3 parts fat to 1 part protein.
No surprise here–this 3:1 ratio is the foundation of the modern keto diet.
The takeaway: Because of the limits on our ability to process protein, an all-meat carnivore diet is, by biological necessity, a keto carnivore diet.
Though research on the carnivore diet is in its infancy, the keto diet has been clinically studied for nearly one hundred years.
Research shows that a keto diet offers numerous benefits, including
Though most of what we know about the benefits of a carnivore diet are self-reported, a quick tour of the #meatheals🥓🍗🍖🥩✌🏻hashtag reveals thousands of inspiring stories of recovery from, and reversal of serious health issues, and dramatic improvements in overall wellbeing.
Reported Carnivore diet benefits include:
The study included data from 2,029 people practicing carnivore for at least six months.
Researchers concluded that “Contrary to common expectations, adults consuming a carnivore diet experienced few adverse effects and instead reported health benefits and high satisfaction.” [17]
The study revealed the following statistics:
The Harvard study reflected similar findings to a survey by Revero, a carnivore diet coaching service. Examining data from 12,000 people practicing a carnivore diet for at least three months found the following. [18]
The benefits of a keto carnivore diet can be attributed to two main factors: (1)What you add to your diet. (2) What you eliminate from your diet.
Let’s explore these factors in greater depth.
Animal products provide structure, plant foods provide stressors
Animal fats, muscle, and micronutrients are the foundation of healthy cell structures and hormonal regulation.
Plant products, on the other hand, come with a bevy of stressors like excess fiber, carbs, and naturally occurring antinutrients and toxins–all of which damage tissues and promote chronic inflammation–the roots of modern diseases.
The key to a healthy and sustainable keto carnivore diet is to focus on fatty animal foods.
The most nutrient-rich and complete keto carnivore foods are ruminant meats, including fatty cuts of steak, and lamb, preferably from grass-fed sources.
Butter, tallow, lard, creamy cheeses, and eggs are also excellent keto-carnivore staples.
Ribeye steak is the centerpiece of most keto carnivore diets. It’s loaded with healthy fats, proteins, and micronutrients like B vitamins, heme iron, and zinc.
While ground beef, bacon, and pork belly are budget-friendly keto carnivore mainstays packed with whole food fats.
Here’s a list of all-star keto carnivore meats with their fat-to-protein ratios.
A tablespoon of tallow, butter, ghee, or lard can bring meals with lean meats like poultry and fish into a keto carnivore macronutrient zone.
Though coffee is not a true carnivore beverage, most people continue to drink it. And the benefits may outweigh the cons. Boost your fat by adding butter to coffee and tea. You can also make a latte with heavy whipping cream.
The carnivore diet is, by default, a keto carnivore diet. This is because when you cut carbs to nearly zero by eating only animal products, you need to get most of your calories from fat. More than 35% of your calories from protein can lead to protein poisoning–a potentially deadly condition.
The good news is that our bodies are designed to thrive on a keto-carnivore diet. In fact, research tells us that our early human ancestors evolved on a diet of almost exclusively fatty meat for nearly two million years. It was only after we ate most giant fatty animals into extinction that we invented agriculture.
Realigning our physiology with ancestral eating patterns reduces inflammation, protects our digestive systems from plant toxins and excess fiber, balances hormones, and provides the nutrients we need to thrive.
