Weight Science Education
The weight science educational video discusses the research on the genetic contribution to body weight; the role of genetics in how individuals' body weight responds to over-eating; the research comparing the efficacy of different dieting approaches; the research on the long-term efficacy of behavioural approaches to weight loss; weight loss in obesity; research on the weight-loss registry looking at successful weight losers; and research on weight control beliefs. The video is narrated by Dr. Michele Laliberte, a licensed clinical psychologist, and the information is consistent with current research and recommendations. There is no deception involved and it is made clear to participants that the information they are being provided is based on current research and the purpose is to understand the impact of this information on their attitudes and beliefs.

Nutrition Education
The healthy nutrition educational video discusses the development of food guides around the world; a definition and description of benefits of the "basics" of healthy eating (e.g., regular eating, balanced eating and pleasurable eating); a review of the macronutrients and their importance to health; a review of the recommendations concerning the specific food groups in the Canada's food guide; and how to put this all together to create a healthy eating plan. The video is narrated by Dr. Michele Laliberte, a licensed clinical psychologist, and the information is consistent with current research and recommendations. There is no deception involved and it is made clear to participants that the information they are being provided is based on current research and the purpose is to understand the impact of this information on their attitudes and beliefs.

Sleep Education
The sleep hygiene educational video, which is an active control, reviews the cognitive, emotional, physical health and weight implications of good quality sleep; provides a review of good sleep hygiene; and provides an overview of how to manage insomnia. The video is narrated by Dr. Michele Laliberte, a licensed clinical psychologist, and the information is consistent with current research and recommendations. There is no deception involved and it is made clear to participants that the information they are being provided is based on current research and the purpose is to understand the impact of this information on their attitudes and beliefs.

About This Trial
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.
