Smoothies, bone broth, and fitspo: the historicity of TikTok postpartum bounce-back culture.

TikTok, a now iconoclastic social media platform, hosts millions of videos on health, wellness and physical fitness, including content on postpartum wellness and 'bouncing back'. At present, few studies analyse the content of postpartum videos urging viewers to bounce-back or the potential influence of these videos. Given the acknowledged relationship between social media use and adverse mental health outcomes (eg, lowered self-esteem, increased stress, disordered eating risk), an investigation of bounce-back-related postpartum content on TikTok explores important intersections between wellness and fitness cultures and the embodied experience of postpartum recovery. Using a qualitative thematic analysis of bounce-back videos (n=175), we explore three themes: (1) Smoothies: eat, but don't be fat; (2) Bone broth: bounce-back with today's wellness trends; (3) Fitspo: moving your body matters. Importantly, videos recycle historically constructed thinking about what makes a 'good' or 'bad' body, invoke vintage diet-culture tropes (ie, drinking water to fill up before eating), and maintain potentially dangerous expectations for caregivers rooted in historical gender, race and class constructs. This results in a postfeminist mishmash of modern maternity practices and traditional hierarchies. Unpacking the historicity of TikTok content assists health practitioners, scholars and users in understanding the potential impacts of video content on new parents, as well as how to flag and contextualise potentially harmful content. Future studies should examine other TikTok subcultures, including teen mothers and trans parents, and explore the messaging directed at and the impact on those communities.
