Night eating syndrome (NES) is classified as an Other Specified Feeding or Eating Disorder (OSFED) under the DSM-5[1]. It involves recurrent episodes of night eating after awakening from sleep or after the evening meal.[2][3] Awareness and recall of the eating is present, which is a key characteristic that differentiates the disorder from Sleep-Related Eating Disorder (SRED).[2][3] Although there is some degree of comorbidity with binge eating disorder (BED), it differs from binge eating in that the amount of food consumed in the night is not necessarily objectively large nor is a loss of control over food intake required.[4][5] The syndrome causes significant distress or functional impairment and cannot be better explained by external influences such as changes in the sleep-wake cycle, social norms, substance use, medication, or another mental or medical disorder.[4][5]
