(Jansen et al., 2009) and changes in appetite are one of the core characteristics of depression (American Psychiatric Association, 1994). Thus, it is not surprising that those who give in to temptation and those with a predisposition to experience depression cannot maintain a steady weight. Finally, of the 30 facets, E4: Activity and C5: Self-Discipline have the strongest associations with exercise behavior (Hoyt et al., 2009) and these two facets shared the strongest negative associations with weight fluctuations: Active and disciplined individuals maintain a more steady weight as they age. Both weight fluctuations and personality have been implicated in the same health outcomes, such as metabolic syndrome and mortality; such fluctuations may be one mediator between traits and these outcomes.
