The effect of a food addiction explanatory model of eating behaviours on weight-based stigma: An experimental investigation.

Weight stigmatization and discrimination are pervasive issues that have numerous adverse consequences for those with excess weight. It has been proposed that some individuals may be addicted to hyperpalatable processed foods, resulting in weight promoting eating behaviours. The current study replicated and extended a study examining the effect of a food addiction explanation for eating behaviours on weight-based stigma and weight-controllability beliefs. Undergraduate students (N = 757) were randomly assigned to one of four conditions where they read a newspaper article accompanied by a photo of a woman 1) who was either of a higher body mass index (BMI) or a lower BMI, and 2) that attributed her eating behaviours to either food addiction or poor dietary and lifestyle choices. Stigma towards the woman and individuals with a higher BMI in general were assessed. Results indicated that the woman with a higher BMI elicited greater weight stigma. Attributing weight to food addiction increased perceptions of psychopathology towards the woman, whereas attributing weight to poor dietary and lifestyle choices elicited judgment towards the woman. Neither explanation about eating behaviours elicited stigma towards individuals with a higher BMI in general. Findings suggest that a food addiction explanation alone may not be sufficient to reduce weight stigma.
