Home > Clinical Information > About Body Composition Analysis Body composition analysis is to diagnose body components quantitatively so that it can provide basic information of the body condition. Body composition analysis is very important in preventive medicine since it provides the basis of appropriate physical activity and dietary formulas for improving daily life. It can also be useful when applied to follow-up studies of patients treated for various diseases. When we are under weight-control, the amount of each component and its proportion in our body change. Since muscle is heavier than the same volume of fat, a person with more muscle looks slimmer. Although it could be important, weight alone does not tell us anything about body composition. Therefore, what is important is our body composition, not our weight, and the well-balanced ratio of its components is a critical health indicator. Body weight alone is not a clear indicator of good health because it does not distinguish how many pounds of fat you have and how many pounds of lean body mass you have. A healthy person maintains a balanced body composition. However, if this balance gets disturbed, the proportion of each component changes; excessive fat causes obesity; insufficient proteins cause malnutrition; excessive water causes edema; insufficient minerals cause osteoporosis. The purpose of body composition analysis is to evaluate the body function and improve your health condition. Therefore, it is to pursue personal health and fitness by understanding the fundamental body condition such as muscle development, nutrition and possible obesity through regular body composition check-ups.
