“Our first study showed that being worried about being stigmatized because of your weight can decrease your self-control and increase stress,” Major said.

“And two big contributors to overeating are stress and feeling out of control. Thus, we predicted that exposing people who think they are overweight to messages emphasizing the stigma overweight people experience could actually cause them to eat more rather than less. And this is just what we found.”

One finding in the current study that surprised her, however, was that women who didn’t perceive themselves as overweight and who read the “Lose Weight or Lose Your Job ”article subsequently reported feeling significantly more in control of their food intake afterward.

“This may partly explain why some people who’ve never had an issue with weight and feel in control of their eating think that weight stigmatizing messages ought to cause people to eat less,” Major said.

“For them, these messages have that effect. But for people who don’t feel in control of their eating, these messages have the opposite effect.”

She suggested that messages related to weight loss would be more effective if they focused on good health and exercise rather than on weight and body mass index (BMI).

“There is good evidence that BMI at very high levels is unhealthy. But people who are in the slightly overweight category actually live longer,” said Major.
