High-protein diets can significantly aid in weight loss due to their ability to increase satiety and reduce overall caloric intake. Protein has a higher thermic effect compared to fats and carbohydrates, meaning the body burns more calories digesting it. Furthermore, protein helps preserve lean muscle mass during weight loss, which is crucial for sustaining a higher metabolic rate. However, it's essential to balance protein intake with fruits, vegetables, and whole grains for a well-rounded diet. Individuals should also be aware of potential nutritional deficiencies if protein sources are not chosen carefully.
