Demystifying ‘diet culture’: Exploring the meaning of diet culture in online ‘anti-diet’ feminist, fat activist, and health professional communities

Social aspects of dieting are discussed in the extant feminist literature. However, despite frequent use of the term ‘diet culture’ in online communities critical of weight-loss dieting and popular books about the harms of restrictive eating, academic studies have not yet investigated its meaning holistically. We used thematic analysis to examine how those in the broad ‘anti-diet movement’ have challenged norms representing ‘diet culture,’ and how the term can be used to unite feminist researchers, activists, and health professionals. One-hundred and eighteen online qualitative survey participants (94.92% female; 37.29% health professionals; 51.70% anti-diet activists; Mage = 36.67) characterised ‘diet culture’ as ‘health myths about food and eating,’ and a ‘moral hierarchy of bodies’ driven by ‘systemic and structural factors.’ Feminist researchers, activists, and health professionals can use ‘diet culture’ to challenge myths and misconceptions about dieting and health, as well as the broader systems and structures that perpetuate these myths.
