Working it off
From the U.S. Department of Health and Human Services, I'm Ira Dreyfuss with HHS HealthBeat. Diet and exercise can help people lose weight. But a study finds an advantage to exercise. Edward Weiss of St. Louis University compared dieters and exercisers in their 50s. His study in the Journal of Applied Physiology was supported by the National Institutes of Health. Dieters cut calories by 16 to 20 percent. Exercisers did the equivalent of a daily one-hour brisk walk. Both groups lost 10 percent of their weight. Dieters also lost muscle. Exercisers did not – and Weiss says the preserved muscle in a lighter body could make their lives easier. "If a person is capable of starting and adhering to an exercise program, they'll be rewarded with the extra benefits that are provided from that. However, if a person just dreads the idea of exercise, there are an enormous number of benefits from diet as well." (14 seconds) Learn more at www.hhs.gov.
