Brief summary

The goal of this clinical trial is to evaluate whether a non-diet nutrition education program can improve eating behaviors, body image, and well-being in normal-BMI women aged 19-35 years. The main questions it aims to answer are: * Does participation in an 8-week non-diet nutrition education program improve eating behavior, body image, and well-being over time in the intervention group compared to the control group? * Is there a significant difference between the intervention and control groups in eating behavior, body image, and well-being after the intervention? Researchers will compare an intervention group receiving an 8-week non-diet nutrition education with a control group receiving no intervention, to see if the program leads to improvements in psychological and behavioral outcomes without focusing on weight loss. Participants will: * Complete pre- and post-intervention assessments, including validated questionnaires on eating behavior (DEBQ, FCQ, IES-2), body image (BAS, Stunkard Figure Rating Scale), and psychological well-being (WHO-5, Rosenberg Self-Esteem Scale), as well as a 3-day food diary. * Be randomly assigned to either the intervention group (8-week online non-diet nutrition education sessions) or the control group (no intervention). * Engage in 8 weekly, 60-minute sessions focused on intuitive eating, body acceptance, and health-promoting nutrition.

Design outcomes

Primary

MeasureTime frameDescription
Eating BehaviorBaseline and 8 weeks after interventionAssessed using the Dutch Eating Behavior Questionnaire (DEBQ): 33 items with three subscales (Restrained Eating, Emotional Eating, External Eating), rated on a 5-point Likert scale (1 = never, 5 = very often). Higher subscale scores indicate greater tendency toward that eating behavior.
Food Choice MotivationBaseline and 8 weeks after interventionAssessed using the Food Choice Questionnaire (FCQ): 36 items, 9 subscales (Health, Mood, Convenience, Sensory Appeal, Natural Content, Price, Weight Control, Familiarity, Ethical Concern), rated on a 4-point Likert scale (1 = not at all important, 4 = very important). Higher scores indicate greater importance assigned to that factor in food choice.
Intuitive EatingBaseline and 8 weeks after interventionAssessed using the Intuitive Eating Scale-2 (IES-2): 23 items, 4 subscales (Unconditional Permission to Eat, Eating for Physical Rather Than Emotional Reasons, Reliance on Hunger and Satiety Cues, Body-Food Choice Congruence), rated on a 5-point Likert scale (1 = strongly disagree, 5 = strongly agree). Higher scores reflect more intuitive eating.
Body AppreciationBaseline and 8 weeks after interventionAssessed using the Body Appreciation Scale (BAS): 9 items, no subscales, rated on a 5-point Likert scale (1 = never, 5 = always). Higher scores indicate greater body appreciation.
Body DissatisfactionBaseline and 8 weeks after interventionAssessed using the Stunkard Figure Rating Scale: visual selection of perceived vs. ideal body silhouette (1-9 scale). Body dissatisfaction is calculated as the difference between the actual and ideal figure selections.
Well-BeingBaseline and 8 weeks after interventionAssessed using the WHO-5 Well-Being Index: 5 items, no subscales, scored 0-5 (0 = at no time, 5 = all the time); raw scores are converted to a 0-100 scale. Higher scores indicate better well-being.
Self-EsteemBaseline and 8 weeks after interventionAssessed using the Rosenberg Self-Esteem Scale (RSES): 10 items, no subscales, rated on a 4-point Likert scale (1 = strongly disagree, 4 = strongly agree). Higher scores reflect greater self-esteem.

Secondary

MeasureTime frameDescription
Dietary IntakeBaseline and 8 weeks after interventionDescription: Assessed via 3-day food record (2 weekdays and 1 weekend day). Food items are recorded by participants using visual portion guides. Analysis performed using eBebis (Turkish Nutrition Database software). Unit of Measure: * Energy intake (kilocalories/day) * Macronutrient intake (grams/day)
