This critical study examines how TikTok content from body positive trends may influence power relations and reinforce female body negative discourses. The study takes its departure primarily in Michel Foucault. However, additional researchers were brought in to expand on Foucault’s ideas by e.g., introducing gender to Foucauldian theory. 30 TikTok videos belonging to two different body positive trends have been collected and undergone a Multimodal Critical Discourse Analysis according to Foucauldian principals. Findings from the analysis illustrated how users acknowledged and heavily depended on societal body negative discourses to create body positive content. More specifically, this was illustrated when users self-categorised as plus size and pointed out body parts e.g., stomach rolls, that are seen as less desirable in society. Users furthermore directly engaged in behaviour, which was found to be body negative e.g., implying the existence of abnormal and imperfect bodies. Effectively, this behaviour was identified as performative and rooted in a fear of being seen as non-progressive and body negativeThe conclusive results of this thesis thus suggest that users inevitably produce and reproduce body negative discourses by relying heavily on the very same discourses in their TikTok communication. Essentially, the users are then contributing to the social and feminist problem of weight-based discrimination and marginalisation.
