High-protein diet foods available for implementing into a diet plan include eggs, fish, beef and poultry. Beans, soy, nuts and seeds are vegetarian and vegan sources for protein. Choosing a wide variety of high-protein sources improves nutrient intake and health benefits associated with dieting.
The benefits of eating protein include increased lean muscle mass while burning fat for fuel and curbing food cravings. Foods that are high in protein take longer to digest and metabolize, which means more calories are utilized trying to process them. The amount of protein needed in a diet varies depending on sex, age, and activity level.
