Researchers at the University of British Columbia, in collaboration with researchers at the University of Leeds and the University of North Carolina, are seeking men and women age 18-75 who are overweight and interested in participating in a weight loss research study.

 

About the research study

  • A total of 360 participants will be enrolled in Canada, the United Kingdom, and the United States
  • The study will last approximately 13 months (for each participant) and the weight loss programs being studied are free
  • The study is investigating the effectiveness of a commercial weight loss program that is widely available in the community (Weight Watcher Freestyle®)
  • Eligible participants who enroll will be randomly assigned to follow the Weight Watchers program or to receive resources to help them follow a 'do-it-yourself' (DIY) approach to weight loss based on personal preferences and lifestyle over a 12 month period
  • Both groups will be asked to make changes to their diet, physical activity and lifestyle in order to lose weight
  • Enrolled participants will be asked to attend 4 appointments at the research center.  During 3 of these, you will be asked  to complete surveys and physical measurements (at the beginning, after 3 months and after 12 months)
  • At the end of the study, each group will be offered the resources provided to the other group (12 months of Weight Watchers or DIY resources)
  • Participants will receive up to $175 for completing the 3 measurement visits
