Protein plays a vital role in achieving satiety and managing weight. High-protein foods tend to be more filling, which helps reduce overall calorie intake by curbing hunger. When consumed, protein triggers the release of hormones like peptide YY and glucagon-like peptide-1, which promote feelings of fullness. Moreover, a diet that includes adequate protein supports muscle maintenance and growth, essential for a healthy metabolism. This combination of reduced hunger and supported muscle mass can be particularly beneficial for effective weight management.
