In this article, I am thinking through the social life of time for food in prison from a practice theory perspective. I draw upon empirical data from in-depth qualitative interviews with people serving custodial sentences or recently released from prison in England and Wales who have been on placement at a prisoner resettlement charity (RC). These support findings from Her Majesty’s Inspectorate for Prisons report on Life Inside: Food from 2016, and I consider two aspects from the report, (i) an exploration of the standards and conditions in which food is consumed and (ii) the timings of mealtimes. For people in prison, disruptions to the usual rhythms of everyday life, or chrono-normative expectations, serve as stark reminders of a lack of agency and worth. People in prison are forced to adapt and work within temporal spaces that are subject to flux due to the systemic demands of an under-resourced prison system. These constitute a contravention of social and cultural norms and reinforce the notion of the prison as a place of punishment, and degradation. These temporal shifts contribute to the transformation of civilian to prisoner and form part of a process of de-synchronising with life outside.
