High-protein diets can significantly influence weight loss by enhancing satiety, boosting metabolism, and preserving muscle mass while losing fat. Higher protein intake has been shown to increase feelings of fullness, leading to lower caloric consumption throughout the day. Additionally, protein-rich foods have a higher thermic effect, meaning the body burns more calories during digestion. Preserving muscle mass during weight loss is crucial, as it helps maintain a healthy metabolic rate. Incorporating protein sources such as lean meats, dairy, legumes, and plant-based proteins can thus support sustainable weight loss while promoting overall health.
