What is the recommended protein intake for athletes per kilogram of body weight?

The recommended protein intake for athletes is indeed in the range of 1.2 to 1.7 grams of protein per kilogram of body weight. This range is established based on the understanding that athletes, especially those involved in endurance training or strength training, have increased protein needs to support muscle repair, recovery, and growth.

This recommendation reflects the additional demands placed on the body during intense training sessions where muscle protein synthesis and energy metabolism are elevated. Consuming protein within this range helps ensure that athletes can meet their physiological needs for optimal performance and recovery.

In contrast, the lower values such as 0.8 g/kg and 1.0 g/kg are typically recommended for sedentary individuals, as they do not account for the unique demands that physical activity imposes on muscle tissue. The highest value of 2.0 g/kg may be considered excessive for most athletes, as consuming protein beyond the necessary levels does not typically yield additional benefits and can lead to unnecessary strain on the kidneys or contribute to an imbalanced diet. Hence, the range of 1.2 to 1.7 g/kg is the most appropriate for athletes.
