Individuals on the NWCR typically eat a low-fat diet rich in complex carbohydrates, eat breakfast daily, weigh themselves at least once a week, and are physically active for 60–90 minutes a day.

• 80% of the people are women and 20% are men.
• 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.
