Effects of low caroic diet plus exercise on visceral fat in obesity women

ABSTRACT

Kim, H.S. Effects of low caloric diet plus exercise on visceral fat in obesity women. Exercise Science, 15(1), 17-24, 2006. The purpose of the present study was to determine the loss of visceral fat during weight loss program with diet plus exercise in premenopausal obese women (age; 37.9±7.6 year). Twenty six women (body mass index; 28.4±1.6 kg/m2) participated in aerobic exercise training for 8 weeks. Subjects performed a treadmill and cycle exercise 3 days/weeks for 30-40 min per session under fitness center supervisor. During the training period, to ensure proper daily nutrition, the subjects were instructed to take every day a well-balanced supplemental food developed for very low-energy diets with 1,000 kcal/d. Fat mass, %fat, fat-free mass (FFM), abdominal subcutaneous fat area (SFA), and visceral fat area (VFA) were measured before and after weight loss program. The intervention resulted in significant declines in body weight (-9%), total fat mass (dual energy X-ray absorptiometry; -16%), VFA (-27%), and SFA (-15%) with no change in lean body mass (all, p <0.001). The decrease in VAT was independently related to the change in fat mass (r=0.62, p=0.05). In conclusion, significant reduction in VAT was observed after low caloric diet plus moderate aerobic exercise in mildly obese women. This change may be important in preventing the negative health outcomes associated with the increase in intra-abdominal obesity.

Key words: obesity, visceral fat area, subcutaneous fat area, low caloric diet, aerobic exercise
