Clinical Trial Summary

This study is designed as an observational trial. The objective of this study is to follow-up with participants 3 years after completion of an 18-month comprehensive behavioral weight loss intervention. Outcomes of interest include change in body weight, body composition, physical activity, energy intake, and sleep. In addition, investigators will explore the associations between current physical activity, sleep, and energy intake patterns and body weight regulation.

Description:

A total of 170 participants were initially enrolled in the comprehensive behavioral weight loss intervention.In this study, investigators will conduct a follow-up visit 3 years after the completion of the intervention. Only participants who completed the behavioral weight loss intervention will be enrolled in this study. Participants will undergo testing of body weight, body composition, physical activity patterns, energy intake patterns, sleep patterns, resting metabolic rate, and total daily energy expenditure.

Eligibility

Inclusion Criteria:
