The National Weight Control Registry

How to Join

Are you eligible?

The National Weight Control Registry is a research study that seeks to gather information from people who have successfully lost weight and kept it off. The registry would like to hear from anyone 18 years of age or older who has:

lost at least 30 pounds, and
maintained a weight loss of at least 30 pounds for one year or more

How it works

Individuals enrolling in the registry will be periodically asked to complete questionnaires about their success at losing weight, current weight maintenance strategies and other health-related behaviors. There is no cost to entering the registry and participants receive no compensation. All names are kept confidential.
