Abstract
In this study, I referred the mean of eating disorder from the point of view as an equality between eating, instinct and comfortableness. The eating behavior of human is started as a basal comfortableness and is developed to a measure for human relationship or a behavior, which is necessary to be controlled. It should be a base of whole comfortableness, but it is so hard for contemporary females to obtain such basal feeling of pleasure, especially in cases with eating disorder. Various episode from their life history and eating behavior, imply inequality between eating and comfortableness. And women are fed from complicated elements although men are able to be fed from change the style of feeding in a turning period of their lives. That is very hard task for females. In past, women had no conflict to decide the lifestyle by themselves, however in present, they are confused in front of innumerable optional dictions. Many contemporary females would be able to breakthrough such conflict by powered from better meals than past foods. But patient with eating disorder have so poor energy to confront such conflict because they miss to basal comfortableness of eating by many reasons. Thus they would be suffered from eating disorder. The trigger of the first onset of eating disorder is trouble human relationships in whole patients, and they obsess to eating, which have intimate relation with communication. They are seemed to deny development of human relationships. From above phenomenon, I hypothesize the onset of eating disorder as follows; The first learning is about the equality between eating and comfortableness and the equality between eating and management of human relationships is second. These would develop interactivity. The third element is development of human relationships in each life-stage, I speculate that eating influence closely to it. The fourth, these are task for only women, not men. In conclusion, I thought as like as mathematically, that the first onset of eating disorder would appear when the absolute product of the 1st. and 2nd. is less than sum of the 3rd. and 4th. elements.
