A high-protein diet can significantly affect weight management by enhancing satiety, which leads to reduced calorie intake. Protein has a higher thermic effect compared to fats and carbohydrates, meaning the body burns more calories during its digestion. Increased protein intake can also help preserve muscle mass during weight loss, which is crucial since a higher muscle mass can increase metabolism. Additionally, protein can help regulate hormones that control hunger, such as ghrelin and peptide YY, contributing to a feeling of fullness. However, the success of a high-protein diet also relies on overall nutritional balance and physical activity.
