Education over dieting: study tests if knowledge can break unhealthy weight beliefs
NCT ID NCT07349316
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether teaching female undergraduate dieters about genetics and healthy eating can shift their beliefs about weight control. Participants will watch educational videos and complete questionnaires on body image, self-esteem, and eating habits. The goal is to see if understanding how the body naturally regulates weight leads to healthier attitudes and less restrictive dieting.

- Weight science and nutrition education videos
- What this could lead to
- If successful, this could show that teaching people about genetics and healthy eating improves body image and reduces unhealthy dieting.
- What could go wrong
- This is an early-stage study with only 150 participants, so results may not apply to everyone. It tests beliefs and intentions, not actual weight loss or health outcomes.
