In What Way Is the Diagnostic Classification of Binge Eating

In what way is the diagnostic classification of binge eating disorder (BED) differentiated from other eating disorders?

A) BED diagnosis requires the person to show significant weight loss despite episodes of binge-eating, which differentiates it from normal over-eating.
B) BED diagnosis requires at least two purges per week, which differentiates it from anorexia-nervosa binge eating-purging type.
C) BED diagnosis requires restrictive behaviours for at least 6 months, which differentiates it from bulimia nervosa.
D) BED diagnosis requires an absence of compensatory behaviours (purging, fasting, excessive exercise) , which differentiates it from bulimia nervosa.
