简要总结
People who diet typically believe they can control their weight. People who believe they should control their weight are more likely to have poor body image, low self-esteem and disordered eating. People who believe they should aim for a healthy lifestyle and accept their natural weight have better body image, better self-esteem and less disordered eating. This study will compare three types of education in undergraduate dieters. In the first, the investigators will teach how the body naturally controls weight. In the second, the investigators will teach about healthy eating. In the third, the investigators will teach about how the body naturally controls weight and healthy eating. The study is testing whether teaching about how the body naturally controls weight and healthy eating changes people's beliefs about weight. The study also tests whether changing people's beliefs about weight will change their body satisfaction, their feelings about themselves, and their intention to diet.

研究组 & 干预措施
Weight Science Education and Sleep Education (Control)
Participants in the Weight Science Education and Sleep Education (Control) arm will be receiving both those educational interventions after answering questionnaires. This arm assesses the hypothesis that weight science education alone will decrease belief in personal control over weight and will have little to no effect on belief in choosing a healthy lifestyle/weight acceptance.
干预措施: Sleep Education (Other)

Nutrition Education and Sleep Education (Control)
Participants in the Nutrition Education and Sleep Education (Control) arm will be receiving both those educational interventions after answering questionnaires. This arm assesses the hypothesis that nutrition education alone will increase belief in choosing a healthy lifestyle or weight acceptance, but will have little to no effect on the belief in personal control over weight.

Weight Science Education and Nutrition Education
Participants in the Weight Science Education and Healthy Eating Education arm will be receiving both those educational interventions after answering questionnaires. This arm assesses the main hypothesis that weight science and nutrition teaching combined will both decrease the belief of personal control over weight and an increase the belief in choosing a healthy lifestyle/weight acceptance.

结局指标
主要结局
Change in beliefs on the ability to control one's weight (weight control beliefs).
时间窗: From baseline measure to the end of the intervention at approximately one hour.
Decreased score on the Weight Control Beliefs questionnaire post-intervention compared to pre-intervention questionnaire score, where a total score of 17 is equivalent to beliefs that weight is not entirely under personal control and a total score of 68 indicates beliefs that weight is entirely under personal control.
次要结局
- Change in restrained eating(From baseline measure to the end of the intervention at approximately one hour.)
- Change in the intent to diet(From baseline measure to the end of the intervention at approximately one hour.)
- Change in self-esteem(From baseline measure to the end of the intervention at approximately one hour.)
- Change in body appreciation(From baseline measure to the end of the intervention at approximately one hour.)
