Overeating

Overeating generally refers to the long-term consumption of excess food in relation to the energy that an organism expends (or expels via excretion), leading to weight gaining and often obesity. It may be regarded as an eating disorder.

This term may also be used to refer to specific episodes of over-consumption. For example, many people overeat during festivities or while on holiday.

Overeating can sometimes be a symptom of binge eating disorder or bulimia.

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