Most of us have slipped out of bed for a midnight snack. But frequent nighttime cravings could signal nocturnal binge eating, a recognized eating disorder.
Whether it's bread with cheese, chocolate brioche, or a handful of biscuits, nighttime hunger strikes us all occasionally. However, if it happens too often, it warrants attention. In an April 14, 2021, Doctissimo article, dietician-nutritionist Véronique Liesse explains that frequent nighttime awakenings to eat may indicate nocturnal binge eating (or nocturnal bulimia).
This eating disorder (ED) involves an irresistible urge to eat at night, often without true hunger. According to the expert, it qualifies as nocturnal bulimia if cravings occur more than twice a week for at least six months. It affects both men and women equally.
Nighttime eating often stems from daytime calorie deficits, triggering hypoglycemia and hunger signals—a normal response, not inherently pathological. Food restriction during the day can also lead to rebellion at night, where forbidden treats like fatty or sugary foods are consumed. This deprivation-rebound pattern creates a true vicious circle. Stress, anxiety, or depression may drive it too, with comfort foods like candy, chocolate, and cakes providing temporary solace.
Unfortunately, these habits promote weight gain, as calories consumed at night go unburned without activity. High-calorie choices exacerbate this. A 2017 study showed that eating around 3am—peak melatonin time—enhances fat storage.
Eating disorders like anorexia nervosa, bulimia, and binge eating impact 5 to 10% of the population.
