The five treatment philosophies and theories are Psychodynamic, Cognitive behavioral, interpersonal, Dialectical behavior, and addiction/twelve-step. Psychodynamic therapy is the view of behaviors emphasizes internal conflict, motives, and unconscious forces. There are many theories of on the development of psychological disorders in particular. The common feature of this theory is the belief that the underlying causes of disordered behaviors are not addressed and resolved, it may subside for a time but will often return. In all psychodynamic theories symptoms are seen as expressions of a struggling inner self that uses the disordered eating and weight control behaviors as a way to communicate or expressing underlying issues. Symptoms are viewed as useful for clients. Cognitive behavioral therapy is the most well-known and studied technique or treatment approach currently used to challenge, manage, and transform specific food and weight- related behaviors. It was developed in the 1970s by Aaron beck as a technique for treating depression. CBT are feelings and behaviors that are created by cognitions. CBT uses homework, journals, and monitoring outside of the sessions. Educating clients about dieting, purging, medical complications and so on is an important part of this model.

Interpersonal therapy focuses on the link between eating disorders and underlying relationship issues. During this showing it showed efficacy in treating bulimia nervosa and binge eating disorders. People that have interpersonal problems that play an important role in the onset and continuation of the disorder.
