Summary

This study is a randomized controlled trial (RCT) of the Weight Watchers (WW) Freestyle ® (Flex® in UK) weight loss program compared to a control group following a do-it-yourself (DIY) approach for 12 months. Participants in the United States, Canada and the UK (n=360 total) will be randomly assigned to either participate in the commercially available WW program in their local community or to follow their own approach for weight loss. This study will examine the impact of the WW program on weight, fitness levels, quality of life, health behaviors and other health outcomes in overweight and obese adults after 3 and 12 months.

Conditions

Interventions

BEHAVIORAL

Weight Watchers Freestyle (Flex)

Participants will be referred to their local Weight Watchers meeting and provided with a promotional code to allow them to participate in the Weight Watchers program free of charge for 12 months. At the randomization visit, study staff will help participants identify a convenient Weight Watchers meeting location and download the program app onto their smartphone.

BEHAVIORAL

DIY Personal Plan

Participants will be provided with a written resource with descriptions of a variety of approaches that have been shown to promote healthy weight loss through behavioral modification. Participants will be encouraged to assess their preferences for dietary change and physical activity and adopt an approach that will lead to negative energy balance and moderate (1-2 lbs. per week) weight loss.
