Effects of a very-low-calorie (420 kcal/day), high-protein diet (70 g/day) and realimentation on weight and body composition of 15 obese, middle-aged women were examined in a 4-6 mo study. Mean weight loss was 20.5 kg (1.1 kg/wk). Fat accounted for 83% and lean body mass (LBM) for 17% of total body weight loss. Multiple regression equations estimated from anthropometric measures were developed to predict the body density of obese individuals both before and after weight loss. Best predictors of body density in obese women before and after weight loss were circumference measurements in the trunk area. Nine previously published population specific and generalized equations for predicting body fat in women were not strongly enough correlated with body fat values obtained by densitometry in this study to be of use clinically.
在一项为期4至6个月的研究中,对15名肥胖中年女性进行了极低热量(420千卡/天)、高蛋白饮食(70克/天)以及恢复正常饮食对体重和身体成分影响的研究。平均体重减轻了20.5千克(1.1千克/周)。总体重减轻中,脂肪占83%,瘦体重(LBM)占17%。根据人体测量数据建立了多元回归方程,以预测肥胖个体在减肥前后的身体密度。肥胖女性减肥前后身体密度的最佳预测指标是躯干区域的周长测量值。此前发表的9个针对特定人群和通用的女性体脂预测方程,与本研究中通过密度测定法获得的体脂值相关性不够强,无法在临床上使用。
