This article approaches snacking from a practice theory perspective in order to understand how this reframing may afford new insights. In doing so it also contributes to sociological thinking on eating practices and their reproduction as well as re ﬂ ecting upon the ontological assertions of practice theory and its theory of social change. In particular this article argues that the re-conceptualisation serves to clarify a sociological research agenda for eating practices associated with snacking. It is argued that setting snacking within routine temporalities and spatialities and as bound up in the recursivity between practices and relations is especially important for thinking about snacking sociologically. In common with applications of practice theory in the ﬁeld of sustainability transitions the aim is to move beyond individualistic assumptions of behaviour change and instead situate snacking as an eating practice with health implications that has emerged within the social, temporal, economic and cultural organisation of everyday life.
