Chewing food and then spitting it out is not a type of eating disorder (ED), but it is a maladaptive behavior that can be found in some of these disorders, such as anorexia nervosa or bulimia.

What people seek with this behavior, stemming from a fear of gaining weight, is to experience the taste of food (chewing it) without ingesting the calories or nutrients derived from eating (spitting it out). This behavior can lead to malnutrition. It is always important to consult with professionals.
