背景和目的：越来越多的证据表明，超重和体脂水平可能导致各种疾病。低热量饮食被发现可以减少体重和脂肪;然而，95%的患者在短时间内恢复体重。本研究的目的是调查低热量饮食和不运动对身体成分的影响，以及评估干预结束后18周体重减轻的维持情况。研究方法：206名超重和/或肥胖的妇女被计算机随机分配到仅饮食（DO）或饮食和运动（DE），为期18周的干预期和18周的维持期。统计学显著性设定为p < 0.05。结果如下：干预期结束后18周，DE组的体重指数（BMI）降低了5.1，而DO组为3.2;运动组的腰围（WC）降低了14.2 cm，仅饮食组降低了8 cm，DE组的体脂降低了15.5%，而DO组没有观察到变化。结论：低热量饮食与运动相结合可以成功地降低体重、BMI、WC和体脂水平。版权所有（C）2011 S.

Background and Aims: 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. Methods: 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. Results: 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. Conclusion: A combination of a reduced-calorie diet with exercise may successfully reduce weight, BMI, WC and body fat levels. Copyright (C) 2011 S. Karger AG, Basel
