The effect of protein on weight management is substantial, as it plays a pivotal role in promoting feelings of satiety and reducing overall caloric intake. Consuming high-protein foods can help stabilize blood sugar levels and diminish cravings, making it easier to adhere to a healthy eating plan. Protein also assists in preserving lean muscle mass during weight loss, which is crucial for maintaining metabolic rate. Moreover, the thermic effect of food (TEF) indicates that protein requires more energy for digestion, further contributing to an increased caloric expenditure.
