A “high-protein” diet is a dietary pattern that emphasizes consuming a significant proportion of calories from protein-rich foods. Proteins are macronutrients made up of amino acids, which are essential for various bodily functions, including muscle repair and growth, hormone production, immune function, and enzyme activity.
High-protein diets often include sources such as lean meats, poultry, fish, eggs, dairy products, legumes, nuts, seeds, and protein supplements. Some popular high-protein diets, like the Atkins Diet or the Paleo Diet, emphasize animal-based protein sources, while others, like the Mediterranean Diet or vegetarian/vegan diets, incorporate a combination of plant-based and animal-based proteins.
