The contemporary phenomenon of “Pro-ana” (or, more accurately, “Ana-mia”) websites, focusing on anorexia nervosa and on other eating disorders, calls into question the notions of body, presence, and performativity. Through their texts, videos, and pictures, bloggers and online forum members document their daily activities and their aesthetic sensibilities. Stigmatized by public opinion, they adopt radical behaviors, describe themselves as heroic fighters and express themselves using a citizenship terminology, with expressions like “Choice”, “Freedom” and “Right” to be anorexic or bulimic. The relationship between the performers and their online audience is mainly driven by a quest for political support and autonomy. The way to fast, outlined in Kafka’s seminal story “Ein Hungerkünstler”, turns into a collective effort of vigilance and negotiation on the limits of bodily performativity in digital environments, and in the broader context of public life.
