The effects of diet- and exercise-induced weight loss on visceral adipose tissue (VAT) distribution in both men and women have been reviewed. In general, current knowledge is based on studies that have assessed the influence of diet alone on VAT in obese women. For every kilogram of diet-induced weight loss, the corresponding reduction in VAT expressed in absolute terms is approximately 3 to 4 cm2, and in relative terms is approximately 2 to 3%. Thus, a diet-induced weight loss of approximately 12 kg corresponds to a 30 to 35% reduction in VAT. Two studies that consider the effects of exercise per se on VAT report conflicting results.
There appears to be a resistance to VAT reduction in obese women, whereas exercise-induced weight loss is associated with significant reductions in VAT in men. It was also reported that in obese men, reductions in VAT induced by the combination of diet and exercise are not different from those observed in response to diet alone. It is unclear whether the results of these studies reflect a biological truth or are confounded by methodological problems associated with the control of energy intake and expenditure in free-living patients. Evidence suggests that changes in waist circumference and sagittal diameter are well correlated with corresponding changes in VAT. A 1 cm reduction in waist circumference corresponds to a 5 cm2 (4%) reduction in VAT area at the L3 level. Data on the separate effects of diet- and exercise-induced weight loss on VAT from well controlled studies are required to advance current knowledge with respect to the effects of diet and exercise on the adipose tissue depot that conveys the greatest health risk.

BACKGROUND: Visceral adipose tissue (VAT) is associated with greater obesity-related metabolic disturbance.
Many studies have reported preferential loss of VAT with weight loss. OBJECTIVE: This systematic review looks for factors associated with preferential loss of VAT relative to subcutaneous abdominal fat (SAT) during weight loss. DESIGN: Medline and Embase were searched for imaging-based measurements of VAT and subcutaneous abdominal adipose tissue (SAT) before and after weight loss interventions. We examine for factors that influences the percentage change in VAT versus SAT (%deltaV/%deltaS) with weight loss. Linear regression analyses were performed on the complete data set and on subgroups of studies. Factors examined included percentage weight loss, degree of caloric restriction, exercise, initial body mass index (BMI), gender, time of follow-up and baseline VAT/SAT. RESULTS: There were 61 studies with a total of 98 cohort time points extracted. Percentage weight loss was the only variable that influenced %deltaV/%deltaS (r=-0.29, P=0.005).
Modest weight loss generated preferential loss of VAT, but with greater weight loss this effect was attenuated. The method of weight loss was not an influence with one exception. Very-low-calorie diets (VLCDs) provided exceptional short-term (<4 weeks) preferential VAT loss. But this effect was lost by 12-14 weeks. CONCLUSIONS: Visceral adipose tissue is lost preferentially with modest weight loss, but the effect is attenuated with greater weight loss. Acute caloric restriction, using VLCD, produces early preferential loss of VAT. These observations may help to explain the metabolic benefits of modest weight loss.
