This article discusses the social representation of anorexia and the social identity constructed by groups of young women who take part of anorexic communities in Orkut. We randomly selected 42 answers to the question: “who am I”, proposed in the beginning of each blog of members of anorexic communities in Orkut, in which the members, all female, describe herselves as being anorexic or as having anorexic behavior. Alceste (Analysis of Lexical Context of a Set of Text Segments) software was used in the analysis of the collected data. We perceived a social representation of anorexia as a lifestyle, and not as an illness, and another one of the anorexia being like a “saint” or “goddess”, thus marking a strange connection of love and hatred between the young women and this kind of protective and powerful super entity. Moreover, it is observed that such representations generate and support the construction by the group of a social identity of the anorexic as having a more developed moral sense and purity. Finally, we noted an overvaluation of anorexic and bulimic behaviors, which can make difficult the adhesion of the young women to the treatment.
