2009 by Taylor and Francis Group, LLC. It is commonly believed that a calorie is a calorie. Consequently, many believe that weight management is simply a problem of balancing caloric intake with energy expenditure. However, this is not always the case. Weight management involves a proper mix of dietary influences and exercise regimens. Many individuals who work out are trying to gain muscle weight to improve their physique, increase strength, enhance performance, or slow the aging process. While gaining weight is too easy for many of us, some athletes have difficulty gaining weight or maintaining it throughout a competitive season. Additionally, it is much harder to gain the right type of weight (i.e., muscle). Also, many athletes and recreationalists would like to lose fat weight safely and healthily. This leads many athletes to consume too many or too few calories based on their needs. Thus, weight management includes an understanding of key concepts, macronutrient composition, and nutritional supplements.
