A high-protein diet benefits athletes by supporting muscle repair and growth after intense training. Proteins provide the essential amino acids needed for muscle synthesis, facilitating recovery and enhancing performance. Increased protein intake can also help in maintaining lean body mass while promoting fat loss, important for athletes looking to optimize their body composition. Additionally, protein can increase feelings of fullness, aiding in appetite control. Timing protein consumption, such as post-workout, can further amplify these benefits, making it a critical component of an athlete's nutrition plan.
