Protein significantly affects satiety and weight management by promoting a feeling of fullness and reducing overall caloric intake. Meals rich in protein can delay emptying of the stomach and enhance the release of hormones that signal fullness, making it easier to stick to dietary goals. Additionally, including adequate protein in a diet can help preserve lean muscle mass during weight loss efforts, which is vital for maintaining a healthy metabolism. Thus, incorporating protein into meals can be a beneficial strategy for those seeking to manage their weight effectively.
