Abstract

Background: A normal balance of body fat is associated with good health and life longevity. The issue of excess fat in relation to lean body mass, a condition known as altered body composition, can greatly increase risk of cardiovascular disease and more. Methods: There were 57 healthy subjects (Female, age 39.0 ± 8.0, BMI 29.1 ± 3.1) recruited from the general population. The first group (n=28) was assigned targeted a reducing diet. The second group (n=29) went through the controlled aerobic exercise in addition to the same diet. The basic anthropometrical parameters and measurement of body composition were used to evaluate the success of the programs. Results: At 1st group was higher weight loss than the 2nd, but this weight loss included decrease of the fat tissue and the loss of the muscle mass (decrease of weight was significant; the decrease of the fat tissue was not). The loss of the fat tissue as well as the increase of the muscle mass at group 2 was significant. Conclusions: The commonly used anthropometrical parameters such as BMI and WC are sufficient for a basic assessment of weight change and alert to the risk of increased fat in the abdominal area. However, the evaluation of reduction programs should concentrate on the changes in body composition that cannot be captured by the BMI and WC. Therefore, it is necessary to apply more sophisticated methods, such as the BIA.
