The Impact of Weightism and Weight Self-Stigma on Obese Population: A Systematic Review

The prevalence of weightism and weight self-stigma are gaining more prominence globally; however, the awareness of its impact is yet to be established. This review aimed to fill the literature gaps and provide a robust and up-to-date account of the biological, psychological, social, and behavioral impact of weightism and weight self-stigma on the obese population. By using a systematic approach, this review utilized five academic databases (PubMed, Scopus, PsycInfo, Medline, Web of Science) to systematically search for studies. Thirty eligible studies met the inclusion criteria with a total of 31,221 participants and these studies either measured the impact of weightism, weight self-stigma or both on the obese population. All the studies were found to have consistent evidence on the impact of weight stigma and weight self-stigma on the obese population such as psychological distress, high body mass index (BMI), body dissatisfaction, disordered eating and more. Researchers are recommended to explore the impact of weight stigma and weight self-stigma in the Asian population as well due to the lack of evidence. The findings of this review provided significant implications and future directions for developing interventions that address weight self-stigma to improve physical and psychological well-being.
