This diet is rooted in the belief that our distant ancestors primarily consumed animal flesh and organs, making it the most natural and healthiest way to nourish the body. The diet revolves around the consumption of various types of meat, such as beef, pork, poultry, and fish, including both muscle meat and organ meats like liver and kidney. Carbohydrate intake is significantly reduced or eliminated altogether, resulting in a very low-carb or zero-carb diet.
