The authors theorized that overweight individuals experience social identity threat in situations that activate concerns about weight stigma, causing them to experience increased stress and reduced self-control. To test these predictions, women who varied in body mass index (BMI) gave a speech on why they would make a good dating partner. Half thought they were videotaped (weight visible); the remainder thought they were audiotaped (weight not visible). As predicted, higher BMI was associated with increased blood pressure and poorer performance on a measure of executive control when weight was visible and concerns about stigma were activated but not when weight was not visible. Compared to average weight women, overweight women also reported more stress-related emotions when videotaped versus audiotaped. Findings suggest that weight stigma can be detrimental to mental and physical health and deplete self-regulatory resources necessary for weight control.
