The role of protein in a balanced diet for active individuals is essential for muscle repair and growth. After exercise, protein assists in the recovery process by repairing damaged muscle fibers and promoting muscle synthesis. It also helps regulate metabolism and maintains a healthy weight by offering satiety. Active individuals require adequate protein intake to support their training goals and overall performance. Sources of protein include lean meats, dairy products, legumes, and plant-based options, ensuring a well-rounded dietary approach.
