The correct answer is True.
Step-by-step explanation
When a person suffers a significant loss, they usually have negative feelings such as sadness, anger, helplessness, frustration, among others. Also, these thoughts focus on negative or nostalgic situations that only contribute to the person falling into a vicious circle in which he or she will not be able to overcome this attitude and will neglect his/her own life for not feeling a reason to live. In this situation, exercise and diet are ways to repair these feelings because they will motivate the person to improve every day in the sport they practice and the diet will make the person take much more care of their health and nutrition to perform better in the exercise, which means the person might stop focusing on the loss and instead improve himself/herself. So, the correct answer is True.
