The term refers to a collection of culinary preparations, designed specifically for consumption during the initial meal of the day, which adhere strictly to a dietary regimen composed exclusively of animal products. These recipes exclude plant-based foods, encompassing meat, poultry, fish, eggs, and certain dairy items like butter or cheese. An example is a simple scramble made with beef tallow and seasoned with salt, or a steak cooked in butter.
Adherence to this restrictive food intake pattern is posited by some to offer potential advantages such as enhanced satiety, simplified digestion for individuals with specific sensitivities, and a reduction in carbohydrate consumption. The roots of this eating approach can be traced to ancestral patterns of nourishment, particularly among populations where animal resources were the primary or sole available food source.
