Trade-offs between current and future consequences are characteristic for the domain of health behavior. Therefore, both eating and exercising behavior could be determined by time orientation (i.e., an individual’s general orientation toward the present or the future). The main aim of this dissertation is to provide insight into the relations between time orientation and both eating and exercising behavior. The results show that time orientation for food and for exercise are different constructs. Moreover, eating behavior is mainly predicted by consideration of immediate consequences, whereas exercising behavior is mainly predicted by consideration of future consequences. Finally, future orientation is related to healthier food choices through a higher construal level. The insights that have been gained in this dissertation contribute to a better understanding of individuals’ intertemporal decision making in the health domain and can ultimately be used in order stimulate healthy eating and exercising behavior.
