How will injury or illness affect energy balance?

Injury or illness can significantly disrupt energy balance by increasing the body's metabolic demands for healing and recovery, which may lead to increased caloric needs. At the same time, physical activity levels often decrease due to pain or mobility restrictions, potentially resulting in reduced energy expenditure. This imbalance can lead to weight loss if caloric intake doesn't match the increased needs or weight gain if intake exceeds reduced expenditure. Overall, managing nutrition becomes crucial to support recovery while maintaining a healthy energy balance.
