Abstract:
BACKGROUND: Obesity and its complicatians are increasing as social ecanamic standard of living is improving and life style has been changing in Korea. There is growing evidence that the visceral/subcutaneous adipose tissue area ratio (VSR) on computed tomography (CI) is closely related to the obesity camplications. Therefore, it is important to determine whether the VSR reduction is praduced during weight loss. The purpose of this study was to observe and campare the amount of reduction of intraabdaminal fat between low calorie diet (LCD) alane and LCD with exercise. METHODS: Sixty obese females were randomly prescribed a LCD alone or a LCD with exercise. Thirty obese females were treated with a LCD of 1,000kcal/d for 8 weeks (group A). Another thirty obese females were treated with a LCD of 1,000kcal/d combined with supervised aerobic exercise for 8 weeks (group B). Weight, height, BMI, and body fat distribution were measured in all subjects immediately before and after 8 weeks of this study. The body fat distribution was assessed by CT, by which the total abdaminal adipose tissue area (AT), subcutaneous abdominal adipose tissue (SAT), intra-abdominal adipose tissue (VAT), and visceral/subcutaneous adipose tissue area ratio (VSR) were measured at the level of the umbilicus. A venous blood sample was taken after an overnight fast to determine lipid, glucose, and insulin concentrations in all subjects before and after 8 weeks of this study. RESULTS: Body weight, BMI, CI' measurement of total (AT), visceral (VAT), and subcutaneous (SAT) fat were found to be decreased significantly in the two groups. The VSR of the group A did not change after weight loss. In contrast, the VSR of the group B decreased significantly (P<0.05) during weight loss. Fasting plasma glucose and total cholesterol levels significantly decreased in the both groups (P<0.001). Fasting plasma insulin and triglyceride levels significantly decreased in the group B, but not in group A. CONCLUSIONS: This study shows that the VSR decreased significantly in group B, but not in group A. Fasting plasma insulin and triglyceride levels decreased significantly in group B, but not in group A. These results suggest that the LCD with exercise is more effective in reducing expected complications of obesity than LCD alone.
