What is the Nation Weight Control Registry?
The National Weight Control Registry (NWCR) is the largest prospective investigation of long-term successful weight loss maintenance and was established in 1994 with the purpose of allowing people to register online if they have lost thirty pounds and maintained their weight loss for one year. Registered users are given detailed questionnaires and annual follow-up surveys are conducted to examine the behavioral and psychological characteristics of participants, as well as the strategies they use to maintain their weight loss. The NCWR follows, observes, and records the data of over ten-thousand individuals and from this information we can see the consistency of the people who have maintained their weight loss and replicate the same methods in our patients.
