Official title
Physiology of the Weight Reduced State
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to determine the physiological basis for the differences in weight regain among adults (25-59 years old) with obesity following participation in a behavioral weight loss program. Eligible participants will undergo a baseline evaluation after which they will enter an up to 20 week behavioral weight loss program with the goal of losing at least 7 percent of their baseline weight within 35 weeks. Participants who meet the weight loss goal will be asked to remain weight stable for 2 weeks after which they will undergo a clinical examination. They will then be observed for 1 year during which they will undergo 2 additional clinical examinations, one 4 months after completing the weight loss program, and the other 12 months after completing the weight loss program.
