Weight loss stigma – sometimes called weight-based discrimination – leads to stereotyping a person based on his or her weight. Not only does this cause stress eating (and more weight gain), but studies show that weight loss stigma reduces the quality of life in people affected by discrimination.
Stigma doesn’t have to come from external sources, though. It can also be internalized when a person applies stereotypical associations to his or herself.
