Abstract
The effects of viewing media-portrayed idealized body images on eating, self-esteem, body image, and mood among restrained and unrestrained eaters were examined. Study 1 found that restrained eaters (i.e., dieters), but not unrestrained eaters, rated both their ideal and current body sizes as smaller and disinhibited their food intake following exposure to idealized body images. These results suggest that restrained eaters are susceptible to a “thin fantasy” brought about by viewing ideal body images. Study 2 found that strengthening thinness attainability beliefs can further enhance the thin fantasy demonstrated by restrained eaters following exposure to idealized body images. Study 3 examined whether demand characteristics moderate these effects of media-portrayed idealized body images. As predicted, when explicit demand characteristics were present, participants reported feeling worse following exposure to thin models. The complexities of the media’s role in the development and maintenance of body dissatisfaction and dieting behavior are discussed.
