This study examined the effects of time-restricted feeding (TRF; 8-h feeding window/16-h fasting window daily) on sleep. Obese adults ( = 23) followed 8-h TRF for 12 weeks. Pittsburgh Sleep Quality Index (PSQI) total score was below 5 at week 1 (4.7 ± 0.5) and week 12 (4.8 ± 0.7), indicating good sleep quality throughout the trial. Subjective measures of wake time, bedtime, and sleep duration remained unchanged. Findings from this secondary analysis indicate that TRF does not alter sleep quality or duration in subjects with obesity. This study is the first to show that TRF (8-h feeding window/16-h fasting window daily) does not alter sleep quality or duration in subjects with obesity.
这项研究考察了限时进食（TRF；每天 8 小时进食窗口/16 小时禁食窗口）对睡眠的影响。肥胖成年人（n=23）遵循 8 小时 TRF 方案 12 周。匹兹堡睡眠质量指数（PSQI）总分在第 1 周（4.7±0.5）和第 12 周（4.8±0.7）时低于 5，表明整个试验期间睡眠质量良好。主观的清醒时间、就寝时间和睡眠时间测量指标保持不变。这项二次分析的结果表明，TRF 不会改变肥胖受试者的睡眠质量或时长。这项研究首次表明，TRF（每天 8 小时进食窗口/16 小时禁食窗口）不会改变肥胖受试者的睡眠质量或时长。
