A high-protein diet positively affects muscle mass by promoting muscle protein synthesis. Increased protein intake stimulates the process of rebuilding muscle tissue after resistance training, leading to muscle growth over time. Adequate protein consumption helps to optimize recovery and support adaptations to exercise, particularly for strength athletes. However, balance is essential; overconsumption without proper exercise can lead to excess calorie intake. Thus, combining protein-rich foods with a structured workout plan yields the best results for building muscle.
