Study summary

The purpose of this study is to examine how adults can improve their physical activity levels and eating habits using an interactive web-based weight control program and regular contact with a dietician.

Read the detailed description
  • All study participants must have regular access to the Internet, however, the study will not provide this access. Participants will be randomly placed in one of two study groups (Group 1 or Group 2).
  • Group 1 participants will be asked to make 3 in-person visits, each lasting 75-90 minutes. The following information will be collected: name, mailing address, telephone number, and email address. During the study visit, the following measurements will be taken: height, weight, waist circumference, blood pressure and dietary patterns.
  • Group 1 participants will also receive counseling around diet and physical activity from a registered dietician and be asked to use a specialized website that will allow them to track eating and physical activity patterns, learn new weight management skills, interact with the dietician, and receive support from other participants.
  • Group 1 will also receive 5 telephone counseling calls with a health counselor. During the telephone calls, we will teach the participant new skills such as tracking diet and physical activity, goal-setting and staying motivated.
  • Group 2 participants will be asked to make 2 in-person visits, each lasting 75-90 minutes in length. The following information will be collected: your name, mailing address, and telephone number. During the study visit, the following measurements will be taken: height, weight, waist circumference, blood pressure and dietary patterns.
