Non-Diet Nutrition Education and Its Effects on Eating Behavior, Body Image, and Well-Being in Adult Women

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.

Inclusion Criteria:

• Female,
• Aged between 19-35 years,
• Body Mass Index (BMI) between 18.5-24.9,

Exclusion Criteria:

• Pregnant or breastfeeding,
• Diagnosed eating disorder or other psychiatric condition,
• Currently enrolled in a weight loss program,
• Following a restrictive diet due to medical conditions.
