Abstract

Background: Obesity is a global health challenge, with researchers increasingly emphasizing its psychological components. This study was conducted to investigate the effectiveness of acceptance and commitment therapy (ACT) on lifestyle, quality of life and body mass index in overweight individuals.
Methods: This clinical trial selected 60 participants (30 in the intervention group, 30 in the control group) from overweight and obese individuals referring to the Iranian Health Clinic in Isfahan, based on inclusion/exclusion criteria. Participants were assessed at pre-intervention, post-intervention, and follow-up stages using the Weight-Related Lifestyle Questionnaire (WEL). The intervention group received 10 sessions of 1.5-hour ACT specifically adapted for obesity. Data were analyzed using repeated measures ANOVA.
Findings: The results demonstrated that ACT intervention had a positive effect on lifestyle and its subscales (P < 0.05).
Conclusion: Based on the study findings, ACT appears to be effective in improving lifestyle among overweight individuals.
