Answer 2

Binge-Eating Disorder (BED) is a mental disorder characterized by overeating without vomiting. This type of eating disorder was first explained by the  psychiatrist, and researcher Albert Stunkard, in 1959. He called it Night Eating Syndrome(NES). BED often leads to the development of unwanted weight gain or obesity, which can indirectly reinforce further compulsive eating.
