The body's energy balance plays a critical role in weight management, determining whether the body gains, loses, or maintains weight. This balance is the relationship between caloric intake and caloric expenditure. If caloric intake exceeds expenditure, weight gain occurs; conversely, if expenditure surpasses intake, weight loss results. Understanding this balance enables individuals to make informed choices about their diet and exercise routines. Therefore, maintaining a healthy energy balance is essential for achieving and sustaining desired weight outcomes.
