A high-protein diet supports weight loss efforts by promoting satiation and reducing hunger. Protein has a higher thermic effect compared to fats and carbohydrates, meaning it requires more energy to digest, thereby increasing metabolic rate. This can lead to a reduction in overall caloric intake as individuals may feel fuller for longer. Additionally, adequate protein intake preserves muscle mass during weight loss, which is important for maintaining a healthy metabolism. By focusing on protein-rich foods, individuals can effectively support their weight loss journeys.
