Carnivore Diet Explained

What Is the Carnivore Diet?

You may wonder what the carnivore diet explained actually means. This eating pattern is simple but strict. You eat only foods that come from animals. You avoid all plant-based foods. The carnivore diet explained includes:

• Meat, such as beef, and venison

• Poultry, like chicken and turkey

• Fish and seafood

• Eggs

• Some dairy products, such as cheese and butter

You do not eat any vegetables, fruits, grains, legumes, seeds, or nuts. You also avoid foods with carbohydrates, including bread, pasta, and sugar. The carnivore diet explained is a zero-carb diet. Your body uses fat and protein from animal foods for energy instead of carbohydrates. Many people call this a type of ketogenic diet because it puts your body in a state called ketosis.

Nutrition experts describe the carnivore diet as an eating plan that consists exclusively of animal-based foods. You focus on meat, fish, eggs, and some dairy. You exclude all plant foods and carbohydrates.

All-Meat Lifestyle

Living the all-meat lifestyle means you base every meal on animal foods. You do not include any plant foods in your daily eating. The carnivore diet explained as an all-meat lifestyle often raises questions about human history and evolution. Some people believe humans always ate mostly meat. Others think early humans ate more plants. The truth is more complex.

• Fossil evidence shows early humans used tools to get meat from animals over a million years ago.

• Ancient animal bones with cut marks reveal that meat was part of early human diets.

• Anthropologists say meat-eating played a role in human evolution, but plant foods were also important.

• Early humans sometimes scavenged meat from large animals and hunted when possible.

• Chimpanzees, our closest relatives, eat some meat, but plants make up most of their diet.

You can see that the balance between meat and plants changed over time. Early humans adapted to different foods based on where they lived and what was available.

The carnivore diet explained today builds on the idea that humans can thrive on animal foods. Supporters say eating only meat gives you all the nutrients you need. They believe this way of eating matches how our bodies evolved.

If you want to try the all-meat lifestyle, experts suggest you start slowly. Increase your meat intake over time. Watch your health and make changes if needed. Always talk to a healthcare professional before making big changes to your diet.

Allowed Foods on the Carnivore Diet

Meat and Animal Products

When you follow the carnivore diet, you eat only foods that come from animals. You focus on red meat, fish, eggs, and some dairy. You do not include any plant foods. The most common foods you eat on this diet are listed below.

Organ meats and offal are important in the carnivore diet. You eat liver, kidney, heart, tongue, and bone marrow. These foods are rich in vitamins and minerals. For example:
