很少有实验数据支持减少夜间进食会改变健康成年人每日总能量摄入（EI）或体重的观点。本研究主要考察了夜间进食限制（NER）对健康年轻男性每日EI的短期影响。其次，它检查了体重和与NER相关的情绪。采用交叉设计，29名男性(20.9 （SD 2.5）岁；24.4 （SD 2.5) kg/m(2)）开始进行为期2周的NER干预（从19.00至06.00小时消除EI）和为期2周的对照条件，通过为期1周的洗脱期进行平衡和分离。EI和常量营养素摄入量通过电脑评估，24小时多次食物召回，体重通过数字秤，情绪使用情绪状态概况调查。在29名参与者中，27名（93%）完成了研究的所有方面。在NER条件下，参与者每天消耗的总能量少于对照组（10 125 vs 11146 kJ/d; F = 6.41; P = 0.018）。在NER条件下，在19.00至6.00之间没有报告能源消耗；然而，在控制条件下，参与者在19.00至06.00小时的能量摄入为2920 (SD 1347) kJ/d。NER组（-0.4 (SD 1.1) kg）与对照组（+6 (SD 0.9) kg）的体重变化差异有统计学意义（F = 22.68; P < 0.001）。NER组与对照组在总情绪评分或情绪分量表上差异不显著（p < 0.05）。这些发现为NER降低健康年轻男性短期EI提供了支持。
Few experimental data are available to support the notion that reducing night-time eating changes total daily energy intake (EI) or body weight in healthy adults. The present study primarily examined the short-term effect of night eating restriction (NER) on daily EI in healthy young men. It secondarily examined body weight and moods associated with NER. Using a cross-over design, twenty-nine men (20.9 (SD 2.5) years; 24.4 (SD 2.5) kg/m(2)) initiated a 2-week NER intervention (elimination of EI from 19.00 to 06.00 hours) and a 2-week control condition, counterbalanced and separated by a 1-week washout period. EI and macronutrient intake were assessed using computerised, multiple-pass 24 h food recalls, body weight via a digital scale and mood using the Profile of Mood States survey. Of the twenty-nine participants, twenty-seven (93 %) completed all aspects of the study. During the NER condition, the participants consumed less total energy per d than during the control condition (10 125 v. 11146 kJ/d; F = 6.41; P = 0.018). During the NER condition, no energy was reported consumed between 19.00 and 06.00 hours; however, during the control condition, the energy intake of participants was 2920 (SD 1347) kJ/d between 19.00 and 06.00 hours. There was a significant difference in weight change between the NER (-0.4 (SD 1.1) kg) and control (+6 (SD 0.9) kg) conditions (F = 22.68; P < 0.001). Differences in total mood score or mood subscales between the NER and control conditions were not apparent (p > 0.05). These findings provide support for NER decreasing short-term EI in healthy young men.
