Three key nutrients for healing are calories, protein, and water. It can be challenging to adjust your calorie intake when injured. You want to promote healing, but avoid unwanted weight gain. You will need to consider how much your training volume has decreased and how aggressive your rehab regimen is. Calories should not be restricted too much, because you need to protect your existing muscle mass as much as possible. When you don’t eat enough calories, muscle may be broken down. There is also a calorie cost to the body’s healing process, and too few calories may slow things down. Focus on eating nutrient dense foods and avoiding highly processed and high sugar foods. Check your weight frequently and adjust your intake up or down based on trends that you notice.
