In situations involving energy restriction or inactivity due to injury, the body's protein requirements may be elevated to support recovery, preserve lean muscle mass, and maintain overall metabolic function. Research indicates that during these periods, protein intake can be beneficially increased to levels around 2.2 grams per kilogram of body weight.

This higher intake is essential because when energy intake is reduced or physical activity is limited, the body may start to utilize muscle protein as an energy source, which can lead to muscle loss. To counteract this, a significant increase in protein helps to provide the necessary building blocks for tissue repair and muscle preservation.

Furthermore, this increased protein intake is particularly critical in the context of injury recovery, where the physiological demand for protein to support healing processes is heightened. Thus, the recommendation to increase protein intake to 2.2 grams per kilogram aligns with guidelines aimed at optimizing recovery and maintaining muscle integrity during periods of reduced energy consumption and physical activity.
