Binge eating syndrome is the main representative of abnormal eating behavior, and it is typically displayed among bulimia patients. Apart from the core binge eating syndrome which is seen in normal weight bulimia and bulimic anorexia nervosa, binge eating syndrome can be observed in many instances such as borderline schizophrenia or schizophrenia in its prodromal phase, so-called situational bulimia, obesity, and high risk group of people who require reducing their weight. All the instances showing binge eating syndrome should be referred to as "binge eating spectrum." The purpose of this paper is to confirm that the basic structure of the syndrome in that the syndrome which is hypothesized in anorexia nervosa and bulimia nervosa, can be commonly seen through this "spectrum." A case of schizophrenia who displayed binge eating, and two cases of situational bulimia patients were illustrated. Also, it was indicated again that these cases had dietary restraint due to desire to be slim, and showed loss of selfcontrol under the stressful situations. In addition, the author's previous prevalence study on binge eating with a high risk female student and normal female student population was reviewed. There were significant correlations between the rate of binge eating and the score of Eating Inventory (Factor 1 and 2). The case study and the survey revealed that self-control of eating and failure of such self-contrl are important factors among the people who are exhibiting binge eating behavior.
