Answer

Patients with night-eating syndrome have attenuation of the nocturnal rise in plasma melatonin and leptin levels and higher circadian levels of plasma cortisol. These individuals have morning anorexia, evening hyperphagia, and insomnia. In one study, patients with night-eating syndrome averaged 3.6 awakenings per night; 52% of these awakenings were associated with food intake, with a mean intake per ingestion of 1134 kcal. [66]
