The considerable proportion of lipids in a diet primarily composed of animal products is a defining characteristic of this dietary approach. This increased lipid intake, often substantially higher than conventional dietary guidelines, serves as the primary source of energy. For example, individuals adhering to this dietary pattern often consume significant quantities of fatty cuts of meat, rendered fats, and other animal-derived lipid sources.
The emphasis on lipid consumption stems from several key factors. Historically, human populations have adapted to periods of scarce carbohydrate availability by relying on lipids and protein for sustenance. Furthermore, lipids are crucial for hormone production, cell membrane structure, and the absorption of fat-soluble vitamins. Adequate lipid intake is considered essential for maintaining satiety and providing sustained energy levels in the absence of carbohydrates.
