A high-protein diet can significantly impact weight loss and muscle gain. Increased protein intake boosts satiety, helping to control appetite and reduce overall caloric intake. Additionally, protein is essential for muscle repair and growth, especially after resistance training. Consuming adequate amounts supports muscle protein synthesis, enhancing recovery and performance. However, balance is key, as excessive protein should still be part of a well-rounded diet that includes carbohydrates and fats to ensure comprehensive nutrient intake for optimal health.
