Obesity is generally considered to be a growing global health problem that results from changes in the way we live in late modern societies. In this article, we argue that investigating the complexities of contemporary timescapes (i.e. the entanglement of physical, culturally framed and personally experienced times) is of key importance for understanding how ‘the obesity phenomenon’ is conceptualised, performed and acted upon. Analysing both focus groups and print-media articles, we identified three major groups of temporal narratives that shape our perception of obesity: trajectories, temporalities and timing. Each group of narratives follows a different logic and performs a specific kind of ordering work: ontological work that defines what obesity ‘really is’, diagnostic work that assesses the state of contemporary society and moral work that assigns responsibility to act. We show how the narratives are assembled into distinct timescapes that distribute agency in specific ways. Combining data from both focus groups and media articles allows us to analyse how these two discursive arenas are intertwined, as it makes visible how stories travel and converge, but also diverge in quite important ways. This highlights the importance of a multi-arena approach to fully understand the tensions between different framings of health-related issues. The article argues that the difficulties of controlling body weight are closely entangled with a perceived lack of control over time on both collective and individual levels. In conclusion, we suggest time-sensitive approaches for the analysis of health phenomena and the development of corresponding policy measures.
