There is growing evidence that excess body weight and body fat levels may lead to various diseases. A low-calorie diet has been found to reduce body weight and fat; however, 95% of patients regain the weight within a short period of time. The aim of this study was to investigate the effects of a reduced-calorie diet with and without exercise on body composition profile as well as to evaluate maintenance of weight loss 18 weeks after the intervention had concluded.


Two hundred and six overweight and/or obese women were randomized by a computer to either diet only (DO) or diet and exercise (DE) for an 18-week intervention period and 18 weeks of maintenance. Statistical significance was set at p < 0.05.


Body mass index (BMI) was reduced by 5.1 in the DE group compared to 3.2 in the DO group 18 weeks after the intervention period had ended; waist circumference (WC) was 14.2 cm lower in the exercise group and 8 cm lower in the diet alone group, and body fat was reduced by 15.5% in the DE group, while no changes were observed in the DO group.


A combination of a reduced-calorie diet with exercise may successfully reduce weight, BMI, WC and body fat levels.
