限能量平衡膳食对人体成分的影响

Effects of Calorie-Restricted Diet on Body Composition

目的:探讨限能量平衡膳食对人体成分的影响及减重效果。方法:由体重管理团队对57例患者实施限能量平衡膳食,同时予以运动、行为及心理干预,干预时间为3个月,比较干预前后人体成分的变化。结果:与干预前相比,干预后的体重、体脂肪率、体脂肪量、体质量指数、基础代谢、内脏脂肪面积、腰围、腰臀比等均下降(P=0.000);肌肉量的降低无统计学意义(P=0.092);有66.7%的患者体重降低百分比≥3%。结论:限能量平衡膳食对人体成分的影响显著,减重效果较好,值得推广。

Objective:To examine the effects of calorie-restricted diet(CRD)on body compositon and weight loss.Methods:A total of 57 subjects were given CRD,exercise,behavioral,and psychological interventions by a weight management team for 3 months,and then we compared the changes of body composition.Results:Body weight,percent body fat,body fat mass,body mass index,basal metabolism,visceral fat area,waist circumference and waist-hip ratio all decreased(P=0.000);lean muscle mass also reduced,but there was on statistical significance(P=0.092);66.7% subjects had a weight loss of more than 3% of baseline weight.Conclusion:CRD had significant effects on body composition and weight loss.
