A study testing behavior modification for weight loss in people with Obesity and Diet Therapy, run by University of Vermont at 1 site in United States.
Trial summary
The primary purpose of this study was to compare weight loss achieved through a behavioral online intervention vs. a commercial self-help website. The investigators hypothesized that there would be no difference in weight loss between groups. Read more about this study

The primary purpose of this study was to compare weight loss achieved through a behavioral online intervention vs. a commercial self-help website. The investigators hypothesized that there would be no difference in weight loss between groups.
Read the detailed description
Obesity has reached epidemic proportions in the United States. Novel approaches are needed to address this issue on a broad scale. The internet holds promise as a way to disseminate effective weight loss strategies. The primary purpose of this study was to compare weight loss achieved through a behavioral online intervention vs. a commercial self-help website. A second aim was to evaluate the utilization of web components and their relationship to weight loss between groups and within groups in order to determine what aspects of web usage correlate to weight loss.

What does the primary outcome measure?
weight change. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2010; AzTrials last refreshed its copy on 27 Oct 2026.
