Evaluation of a Commercial Program on Weight Loss and Health Outcomes

Early Phase 1

Completed

• Conditions: Obesity; Weight Loss
• Interventions: Behavioral: Modified WW Food program

• Registration Number: NCT03928483
• Lead Sponsor: Medical University of South Carolina

Brief Summary

To examine weight loss and acceptability of a modified WW program. This study is designed to detect differences in weight loss at the end of 24 weeks of intervention.

Detailed Description

This trial is an examination of a modified WW food program. The intention is to document the acceptability and efficacy of the dietary plan over 24 weeks. Subjects will participate in a program similar to WW Freestyle and have access to study-specific weekly workshops and a suite of study-specific digital tools for tracking eating, activity, and weight. Within a WW program, participants are provided instructions on calculating points for the foods and beverages they eat and drink. This study will examine the impact of the modified WW food program on weight and fitness levels of adults with overweight and obesity.
