Body Positivity and Eating Behaviors Among Women Attending Fitness Classes: Associations with Body Mass Index

Background: Body positivity is a social movement aimed at promoting acceptance and appreciation of diverse body types. Despite its growing popularity, its relationship with eating behaviors and body mass index (BMI) remains unclear. This study aimed to investigate the opinions of women attending fitness classes on the body positivity movement and to assess the association between these attitudes, eating behaviors, and BMI. Methods: A total of 118 women aged 18-65 years participated in the study. Data were collected using a self-developed body positivity questionnaire and the validated Polish version of the Three-Factor Eating Questionnaire (TFEQ-13). Participants were stratified into two groups based on BMI (<25 and ≥25 kg/m²). Results: No significant association was found between general attitudes toward body positivity and either eating behaviors or BMI. However, a positive correlation was observed between BMI and emotional eating as well as cognitive restraint. Women with higher BMI demonstrated greater cognitive restraint and tendencies toward emotional eating. Body acceptance was significantly lower in women with BMIs ≥ 25. Conclusions: While general attitudes toward the body positivity movement do not appear to influence eating behaviors directly, body weight is linked to both emotional eating and cognitive restraint. These findings underscore the complex relationship between psychological factors, eating patterns, and body image, suggesting the need for further research and tailored interventions promoting both health and self-acceptance.
