What happened

A viral AI filter on TikTok known as the 'chubby filter' transforms photos to make people appear to have gained weight. Users shared 'before and after' images on the platform, with some making jokes about the transformation, while others criticized the filter as promoting body shaming and fatphobia.

Reported impact

An influencer with 66,000 followers reported receiving messages from women who deleted TikTok because the trend made them feel bad about themselves. A food scientist and nutritionist stated that the filter represents 'a big step backward' in combating stigma against overweight people and warned that fear of weight gain contributes to eating disorders and body dissatisfaction.

Index analysis

Experts described the filter as repeating stereotypes that overweight people are lazy and flawed, and that being like them should be avoided at all costs. The trend was characterized as feeding a 'toxic diet culture' and potentially contributing to the emergence of eating disorders.

Governance controls

TikTok did not respond to BBC requests for comment.
