Study reveals how Fat-Shaming harms health behaviors
NCT ID NCT05402137
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how experiencing weight stigma (being treated negatively because of body size) changes what people eat, how much they move, and how well they sleep. 330 adults with a BMI of 28 or higher from Los Angeles took part. Some were exposed to a person who expressed anti-fat attitudes, while others were not. Their eating, physical activity, and sleep were then measured over several days.
