Description
Summary:Objective Although a considerable amount of research has revealed connections between weight stigma and mental and physical health outcomes, no studies to date have experimentally manipulated the experience of obesity to understand how weight stigma causally affects eating behavior, physiology, and psychological well‐being. Research has also not yet identified effective strategies for reducing weight stigma. Methods In this research, the effect of weight stigma on psychological outcomes, unhealthy eating behavior, and the stress hormone cortisol was examined by randomly assigning participants to appear obese by wearing a fat suit or not. It was hypothesized that the physical alteration of participants' apparent body size would lead to similar consequences as those associated with the experience of weight stigma and reduce antifat attitudes. Results Supporting these hypotheses, experimentally manipulating apparent body size led participants to consume more unhealthy foods and report higher levels of negative effect. However, the study did not show any differences in cortisol reactivity or reduction in antifat attitudes as a function of the fat suit manipulation. Conclusions These findings contribute to an understanding of the potentially deleterious psychological and behavioral effects of weight stigma while also informing future interventions to reduce weight stigma.
