About this study
Official title: The Effect of Non-Diet Nutrition Education on Eating Behavior, Body Image, and Well-Being in Adult Women: A Randomized Controlled Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Non-Diet Nutrition Education ProgramBehavioural
The intervention is an 8-week online nutrition education program based on non-diet approaches, including intuitive eating, rejecting diet mentality, honoring hunger, body acceptance, and well-being. Each weekly session is 60 minutes long and involves interactive discussions and home practices.
| Study group | Role | What they receive |
|---|---|---|
| Intervention Group | Experimental | Participants in this group will receive an 8-week online non-diet nutrition education program based on intuitive eating and body acceptance principles. Receives: Behavioral: Non-Diet Nutrition Education Program |
| Control Group | No intervention | Participants in this group will receive no intervention during the 8-week study period but will complete the same pre- and post-assessments as the intervention group. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Eating Behavior
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Food Choice Motivation
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Intuitive Eating
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Body Appreciation
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Body Dissatisfaction
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Well-Being
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Self-Esteem
Assessed 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.
Measured: Baseline and 8 weeks after intervention
Secondary outcomes (1)

- Macronutrient intake (grams/day)
Measured: Baseline and 8 weeks after intervention
