Mindful Eating in Breast Cancer Survivors: A Pilot Study in Türkiye

The goal of this clinical trial is to explore whether a mindful eating intervention can improve eating behaviors and support sustainable weight management among female breast cancer survivors in Türkiye who have completed active treatment. The main questions it aims to answer are: * Can a structured mindful eating program improve intuitive and mindful eating behaviors? * Does the intervention lead to favorable changes in body weight, BMI, waist circumference, and fat mass compared to usual care? Researchers will compare a group receiving a 6-session mindful eating intervention plus treatment-as-usual (MEI + TAU) to a treatment-as-usual (TAU) control group to see if the intervention provides additional benefits on eating behaviors and body composition. Participants will: * Attend six 60-90 minute group sessions on mindful eating delivered by trained professionals * Receive tailored nutrition education from an oncology dietitian * Complete validated questionnaires (IES-2 and MEQ-30) and anthropometric assessments at baseline and follow-up
