FitLink: Improving Weight Loss Maintenance by Using Digital Data to Provide Support and Accountability

Summary

Most adults in the U.S. are overweight or obese and find maintenance of weight loss difficult. This study is designed to aid in the development of a lifestyle modification program that can facilitate weight loss maintenance, without requiring long-term visits to a clinic for maintenance treatment.

Interventions

BEHAVIORAL

Gold Standard Behavior Therapy for Weight Loss

Group-based behavioral treatment for weight loss, with a standard emphasis on diet (65% of session) and physical activity goals (25% of session). Other weight loss behaviors such as self monitoring will be covered in the remaining time (10% of session). Participants will be asked to utilize digital monitoring devices for physical activity, weight, and diet. Coaches will not have access to the digital data that participants provide on physical activity, weight, and diet monitoring devices.

BEHAVIORAL

Standard Remote Behavior Therapy for Weight Loss

Individual, monthly, brief phone calls with coach and weekly text messages. The content of these calls and messages will be determined by participant self-report. Coaches will not have access to the digital data that participants provide on physical activity, weight, and diet monitoring devices.

BEHAVIORAL

Digital Data Sharing Behavior Therapy for Weight Loss

Individual, monthly, brief phone calls with coach and weekly text messages. The content of these calls and messages will be determined by the digital data that has been shared with the coach from physical activity, weight, and diet monitoring devices.
