The purpose of this study was to determine the loss of visceral fat during weight loss program with diet only or diet plus exercise in premenopausal obese women (age 44 ± 6 yr). One hundred seventeen women (body mass index 29±3 kg/m^2 ) were divided into diet only group (DO, n = 40) and diet plus exercise group (DE, n = 77). DE was further divided into two groups: a group with a small change in V02max (DEi, nr=26) and a group with a large change in V02max (DE_2, n -51). Height, weight, fat mass, %fat, fat-free mass (FFM), abdominal total fat area (TFA), visceral fat area (VFA), subcutaneous fat area (SFA) and V0_2max (ml/kg FFM/min) were measured before and after weight loss. The changes of weight, fat mass, %fat were significantly larger in DE than in DO. No difference was found in the changes of weight, fat mass, %fat between the DE_1 and DE_2. Percentage of change in VFA was significantly larger in DE_2 (41 ± 15%) than in DEi (31 ± 16%). These data suggest that both weight-loss programs (DO and DE) contribute to a remarkable decrease in visceral fat. Addition of exercise training, which would induce an improvement in V0_2max, to dietary restriction, may elicit a greater effect on visceral fat.
