In this qualitative study, we intend to discuss how adolescent students in a Brazilian public school classroom define their body image and personalize the themes "beauty standards" and "fatness." Grounded on a critical approach to language teaching, these two social themes were problematized in eight lessons of "Ensino Médio" (secondary education). The discussion of the empirical material suggests that (1) body image is strongly connected to gendered relations, making life experiences of men and women different based on the bodies they have, and (2) beauty standard and fatness are strongly related to students' lives since twelve out of nineteen students personalized the themes by telling oppressive stories they went through because of their bodies.
