What works for weight loss? Data from the National Weight Control Registry

Some very interesting data revealed by the National Weight Loss Registry

A total of 2886 participants who had lost at least 30 pounds and kept it off for at least one year were enrolled.

Data was collected in 1993-2010 and analysis was conducted in 2012.

It was a 10 year observational study and recently got published in the American Journal of Preventive Medicine.

FINDINGS OF THE REGISTRY!!!

  • The “average” woman is 45 years of age and currently weighs 145 lbs, while the “average” man is 49 years of age and currently weighs 190 lbs.
  • Registry members have lost an average of 66 lbs and kept it off for 5.5 years.
  • These averages, however, hide a lot of diversity:
      • Weight losses have ranged from 30 to 300 lbs.
      • Duration of successful weight loss has ranged from 1 year to 66 years!
      • Some have lost the weight rapidly, while others have lost weight very slowly–over as many as 14 years.
  • We have also started to learn about how the weight loss was accomplished: 45% of registry participants lost the weight on their own and the other 55% lost weight with the help of some type of program.
  • 98% of Registry participants report that they modified their food intake in some way to lose weight.
  • 94% increased their physical activity, with the most frequently reported form of activity being walking.
  • There is variety in how NWCR members keep the weight off. Most report continuing to maintain a low calorie, low fat diet and doing high levels of activity.

 

    • 78% eat breakfast every day.
    • 75% weigh themselves at least once a week.
    • 62% watch less than 10 hours of TV per week.
    • 90% exercise, on average, about 1 hour per day. 

 

CONCLUSIONS:

The majority of weight lost by NWCR members is maintained over 10 years. Long-term weight-loss maintenance is possible and requires sustained behavior change. 80% of persons in the registry are women and 20% are men.
