Recent research reveals that other more discrete factors, like “Knowledge-based work (KBW)” have been identified as a potential factor that induces overeating and/or obesity in workers, mostly in women. That might be the explanation for epidemic obesity in person stress-exposed in work-place for a long time. Based on auto-regulation theory, the goal of this paper was to explore the relations between psychological characteristics, mental work-related efforts, and food intake, a cause which is capable to explain the very high incidence and prevalence of epidemic obesity in this kind of population (occupational category). The results are in agreement with the current literature. However, the controlled motivation variable shows no association with bodily satisfaction even though this relationship is well documented in women. Additional researches are needed to total understanding of complex interactions, the reasons underlying this association partially known between KBW, psychological characteristics, and ad libitum food intake.
