• ChatGPT supported Online Guided Self-Help Program (GSHP) (Behavioral): Guided Self-Help Program (GSHP) The Guided Self-Help Program (GSHP) was developed by Fairburn and Carter for patients with binge eating disorder and later adapted to address various eating behaviors, forming an intervention protocol. GSHP modules consist of: Starting self-monitoring, Establishing regular eating patterns, Applying the "mindful eating" rule and developing alternatives to emotional eating, Practicing problem-solving exercises, Addressing diet-related issues and body image, and Termination modules. Session Structure: Session 1 focuses on tracking eating patterns and raising self-awareness about eating habits. Individuals are asked to maintain a daily record via a shared Google Forms link.

Primary outcomes

• Dutch Eating Behavior Questionnaire (DEBQ) [8 weeks]: The Dutch Eating Behavior Questionnaire (DEBQ) was developed by Van Strien, Frijters, Jan, Bergers, and Defares (1986) to measure emotional, external, and restrained eating behaviors.

Emotional Eating (13 items) - Example: "Do you have a desire to eat when someone upsets you?" External Eating (10 items) - Example: "Do you feel like eating when you pass by a café or snack bar?" Each item is rated on a 5-point Likert scale (1 = Never, 5 = Very often). The 31st item is reverse-scored. The psychometric properties of the DEBQ were validated in Turkish by Bozan, Baş, and Aşçı (2011), confirming the original three-factor structure. In their study, the Cronbach's alpha coefficients for the subscales were found to be: Emotional Eating: .90 Restrained Eating: .94 External Eating: .96 These reliability values indicate high internal con
