Sleep deprivation consistently increases food intake. This study aimed to evaluate the effect of partial sleep deprivation on food intake in individuals reporting binge eating, controlling for self-reported depressive emotional eating. Fourteen young adults reporting binge eating symptoms and 14 controls denying any eating disorders symptoms were offered a large and varied breakfast after a night of habitual sleep (HN) and after a night of partial sleep deprivation (DN). Food intake was unobtrusively measured while daily food intake was measured via a food diary. Results revealed only a significant effect of the Night on fibre consumed at breakfast and on the amount of daily snacks: both groups consumed less fibre and more snacks after DN compared to after HN. However, when controlling for depressive emotional eating, results showed that individuals reporting low depressive emotional eating ate less after DN than after HN at breakfast, but then they ate more throughout the day. Partial sleep deprivation may decrease fibre consumption and increase daily snacks regardless of binge eating symptoms, while daily food intake may increase only in individuals who do not report emotional eating.

睡眠剥夺持续增加食物摄入量。本研究旨在评估部分睡眠剥夺对报告有暴饮暴食行为个体食物摄入量的影响，并控制自我报告的抑郁性情绪化进食。14名报告有暴饮暴食症状的年轻成年人和14名否认有任何饮食失调症状的对照组在经历一夜习惯睡眠（HN）和一夜部分睡眠剥夺（DN）后，被提供了一顿丰盛多样的早餐。在不引人注意的情况下测量食物摄入量，同时通过食物日记测量每日食物摄入量。结果显示，仅夜间因素对早餐时摄入的纤维量和每日零食量有显著影响：与HN后相比，两组在DN后摄入的纤维更少，零食更多。然而，在控制抑郁性情绪化进食后，结果表明，报告低抑郁性情绪化进食的个体在DN后早餐时的进食量比HN后少，但随后他们一整天的进食量更多。无论是否有暴饮暴食症状，部分睡眠剥夺可能会减少纤维摄入并增加每日零食量，而每日食物摄入量可能仅在未报告情绪化进食的个体中增加。
