The carnivore diet includes only animal-based foods, excluding all plant products. Core foods include:

Meats: Beef, pork, lamb, chicken, turkey, game meats (venison, bison, elk), and organ meats (liver, heart, kidneys, tongue).
Seafood: Salmon, trout, cod, tuna, shrimp, crab, lobster, scallops, oysters, mussels, clams, squid, and octopus.
Eggs: Chicken, duck, and quail eggs.
Dairy (if tolerated): Butter, ghee, heavy cream, hard cheeses (e.g., cheddar, gouda), and cottage cheese.
Fats: Lard, tallow, bone marrow, and clarified butter.
Emphasized essentials:

Organ meats (e.g., beef liver, chicken heart) are highly recommended for nutrient density.
Fatty cuts of meat (like ribeye, pork belly, or ground beef with higher fat content) are encouraged to meet energy needs.
Bone broth and water are commonly consumed; tea, coffee, and plant-based drinks are discouraged.
Avoid all plant foods, including fruits, vegetables, grains, legumes, nuts, seeds, and processed foods with plant ingredients. Always consult a healthcare professional before starting this restrictive diet due to potential long-term nutritional risks.
