Outpatient dietary weight reduction for obesity is unsatisfactory. The objective of this study was to compare the efficacy of an energy prescription diet with usual care (a healthy eating diet) in adult overweight patients referred to a NHS hospital dietetic outpatient clinic, in terms of weight change over 12 weeks.
Controlled clinical trial (systematic allocation).
Of the 53 patients who attended their first appointment, 27 completed the trial. Mean weight loss (kg) after 12 weeks was 4.2 (sd 3.8) on the energy prescription diet (n = 16) and 6.0 (sd 2.8) on the healthy eating diet (n = 11).
Patients on a weight reducing diet based on energy prescription or healthy eating lost, on average, clinically significant amounts of body weight by 12 weeks. Mean weight loss was greater by about 50% in the healthy eating group and supports the development of a larger trial to estimate true effect.
门诊肥胖患者饮食减重效果不佳。本研究旨在比较能量处方饮食与常规护理（健康饮食）对转诊至英国国家医疗服务体系（NHS）医院饮食门诊的成年超重患者的疗效，观察12周内的体重变化情况。
对照临床试验（系统分配）。
53名首次就诊患者中，27名完成试验。能量处方饮食组（n = 16）12周后的平均体重减轻（kg）为4.2（标准差3.8），健康饮食组（n = 11）为6.0（标准差2.8）。
采用能量处方或健康饮食的减重饮食患者，到12周时平均减轻了临床上显著的体重。健康饮食组的平均体重减轻幅度约高50%，支持开展更大规模试验以评估真实效果。
