The protein requirement for active individuals is significant because it supports both muscle recovery and growth. This group needs higher protein intake to replenish the muscle fibers stressed during exercise, making it vital for achieving strength and performance goals. Specifically, athletes and fitness enthusiasts typically require about 1.2 to 2.0 grams of protein per kilogram of body weight daily, depending on their activity level. Meeting these protein needs through various sources, including lean meats, dairy, and plant-based proteins, is essential for optimal athletic performance and overall health.
