Overeating occurs when an individual consumes more calories than the energy that is expended via physical activity or expelled via excretion, or when they consume food past the point of satiation, often leading to weight gain and often obesity. Overeating is the defining characteristic of binge eating disorder,^[1] and it can be a symptom of bulimia nervosa.^[2][1]

In a broader sense, hyperalimentation includes excessive food administration through other means than eating, e.g. through parenteral nutrition.
