This study compared two types of dietary advice on weight loss, weight maintenance and quality of life in Scottish women. One hundred and twenty-six overweight/obese sedentary women were randomly assigned to either: Group 1, reduced energy, fat and sucrose; Group 2, reduced energy and fat only; or Group 3, control. Subjects were followed up at 3 months and for a further 6 months weight maintenance. Groups 1 and 2 reported a decrease in energy intake, percentage energy fat, and increase in percentage energy total carbohydrate and protein (P < 0.001). Group 1 reduced percentage energy sucrose at 3 months (P < 0.001) but not at 9 months. Groups 1 and 2 lost body weight (2.81 kg [standard error of the mean, 0.406] and 2.6 kg [standard error of the mean, 0.506], respectively), body fat (P < 0.01) and reported increased quality of life (P < 0.05). Group 2 reported more positive changes. Both interventions were successful for weight reduction, and were maintained medium term. The associated increase in quality of life may be indicative of longer term compliance, predicting successful weight maintenance.
这项研究比较了两种饮食建议对苏格兰女性减肥、保持体重和生活质量的影响。126 名超重/肥胖久坐的女性被随机分配到以下三组：组 1，减少能量、脂肪和蔗糖；组 2，减少能量和脂肪；组 3，对照组。在 3 个月和进一步的 6 个月体重维持期间对受试者进行随访。组 1 和组 2 报告能量摄入、脂肪百分比能量和总碳水化合物和蛋白质百分比能量增加（P < 0.001）。组 1 在 3 个月时（P < 0.001）减少了蔗糖百分比能量，但在 9 个月时没有减少。组 1 和组 2 减轻了体重（分别为 2.81 公斤[均值标准误差，0.406]和 2.6 公斤[均值标准误差，0.506]）、体脂肪（P < 0.01），并报告生活质量提高（P < 0.05）。组 2 报告了更多积极的变化。两种干预措施都成功地减轻了体重，并在中期得到维持。生活质量的相关提高可能表明长期的依从性，从而预测成功的体重维持。
