This thesis explores how the female body and identity are discursively constructed on TikTok and in the comment sections of posts responding to the Swedish documentary Smalast vinner (Sveriges television, 2025), which critiques the thinness ideal and influencer-driven body norms. The study analyses how TikTok commenters reproduce or resist postfeminist norms around body image, empowerment, and responsibility. The thesis is guided by the method of the Critical Discourse Analysis (CDA) informed by Fairclough’s three-dimensional model (1995). Four TikToks and their comment sections by Swedish female-presenting influencers were analysed. The analysis reveals that commenters simultaneously reproduce and resist postfeminist ideals. Discourses of empowerment, emotional self-regulation, and bodily self-surveillance coexist with critical voices demanding accountability and exposing the contradictions. Commenters emerge as active participants shaping digital feminist discourse on TikTok. This thesis contributes to feminist media research by centering the comment section as a dynamic discursive space, revealing how commenters construct, contest, and negotiate feminist meaning on TikTok.
