Introduction: Although carbohydrates consumption is a key factor to enhance sport performance, intake levels seem questioned by some amateur athletes, leading to develop an irrational aversion to carbohydrate known as "carbophobia". On the other hand, food is the origin of virtual communities erected as a source of knowledge and a way to exchange information. Despite this, very few studies have analysed the influence of social media in eating behaviours. Objectives: To know the conceptualizations about carbohydrates intake and eating patterns related to carbophobia expressed in amateur athletes' Twitter accounts. Methods: Qualitative research designed from Hine's Virtual Ethnography. Virtual immersion was used for data collection in Twitter open accounts in a theoretical sample of tweets from amateur athletes. Discourse analysis of narrative information of tweets was carried out through open, axial and selective coding process and the constant comparison method. Results: Data analysis revealed four main categories that offered a picture of conceptualizations of carbohydrates: carbohydrates as suspects or guilty from slowing down training, carbophobia as a lifestyle, carbophobia as a religion and finally the love/hate relationship with carbohydrates. Conclusions: Low-carbohydrate diet is considered a healthy lifestyle in some amateur athletes. The results of this study show the power of virtual communication tools such as Twitter to support, promote and maintain uncommon and not necessarily healthy eating behaviours. Future studies should focus on the context in which these practices appear.
