Fundamentals of the Carnivore Diet

The carnivore diet focuses exclusively on animal-based foods, eliminating all plant products. It emphasizes consuming meat, organs, and other animal-derived nutrients.

Definition and Core Principles

The carnivore diet, also known as the all-meat diet or animal-based diet, consists solely of animal products. Adherents consume beef, pork, poultry, fish, eggs, and dairy.

Organ meats play a crucial role due to their nutrient density. Liver, heart, and kidneys are particularly valued for their vitamin and mineral content.

The diet excludes all plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds. Proponents argue that animal foods provide all necessary nutrients.

Water is the primary beverage, though some allow coffee or tea. Supplements are generally discouraged, as the diet aims to meet nutritional needs through food alone.

Comparison with Other Diets

The carnivore diet differs significantly from most mainstream eating plans. It shares some similarities with ketogenic and paleo diets but is more restrictive.

Unlike keto, which allows some plant foods, carnivore eliminates all non-animal sources. This results in virtually zero carbohydrate intake.

Paleo diets include fruits, vegetables, and nuts, while carnivore does not. Both exclude grains and processed foods.

Standard dietary guidelines recommend a mix of food groups. Carnivore contradicts this advice by focusing solely on animal products.

Veganism represents the opposite extreme, excluding all animal-derived foods. Carnivore and vegan diets are polar opposites in their approach to nutrition.
