Abstract: We propose a theoretical model examining the relationship between rational eating, physical exercise, and obesity. We show that the variety of different individual lifestyles observed in eating and physical activity can be rational outcomes. Exploring intertemporal patterns of body weight and exercise, we examine the role of individual characteristics, time constraints, and budget limitations, providing insights into the impact of policy interventions targeting eating and exercise choices. We show that opting for a sedentary lifestyle can be a rational decision, a novel finding not present in the rational eating literature. The interaction between physical inactivity, body weight, and fitness condition generates a spectrum of lifestyles over the lifecycle, ranging from monotonic paths to oscillatory behavior, mirroring empirical observations of individual behaviors and physical conditions. We also show the possible existence of multiple equilibria and of multiple indifferent lifestyles. The former refers to the possibility of reaching different states of health and body weight, depending on the individual initial conditions. The latter refers to trajectories of eating and exercising behavior with the same initial and terminal conditions, that yield the same utility flow, and yet correspond to different lifestyles.
