The intent of this article is to move beyond the work of Weber and construct a concept of health lifestyles applicable to the current phase of modernity. Beginning with the early twentieth-century work of Simmel and Weber on lifestyles generally, we move to mid-century to examine Bourdieu's perspective and turn to Giddens for an analysis of late century conditions. We find that Weber's insight concerning the dialectical interplay of choice and chance remains the central feature of the lifestyle concept. We also suggest that in rapidly changing late or postmodern situations, lifestyles not only provide self-identity but also promote a sense of stability and belonging for an individual by providing an anchor in a particular social constellation of style and activity. Our discussion leads us to define health lifestyles as collective patterns of health-related behavior based on choices from options available to people according to their life chances. Consistent with Bourdieu's notion of habitus, we assign priority to chance (structure) over choice.

Max Weber's concept of formal rationality and ideas about lifestyles in general are applied to current trends in health lifestyles. The central contribution of Weber's thinking is recognition of the dialectical interplay between formal versus substantive rationality, consumption versus production, choice versus life chances, class similarities versus distinctions, and self-control versus conformity in shaping health life-styles and the reality of their operationalization in the postmodern world. In a largely applied subdiscipline like medical sociology, Weber's work offers a theoretical background on which to enrich our understanding of health lifestyles and grapple with the initial theoretical challenges posed by lifestyle research.
