Exercise and ObesityWednesday, March 10, 2010
In the fight against obesity, even a little exercise can help. Dr. Edward Hill discusses a study about exercise and obesity in todays 60 Second Housecall.
While frequent exercise is known to fight obesity and improve mental health, as little as 30 minutes of physical activity one or two days a week can have benefits.
Thats the finding of the 2009 Gallup-Healthways Well-Being Index, based on 288,000 phone interviews.
The index found that the number of days a person exercises for at least 30 minutes is strongly connected with the likelihood of obesity. Not exercising in a given week was associated with a 35 percent incidence of obesity. Exercising for a half hour one to two days a week was associated with a 28 percent incidence of obesity.
Researchers concluded that exercising several days a week seemed about as good, and arguably better, than exercising every day, especially when you consider return on investment.
The findings not only support the notion that exercise may boost well-being, but they also suggest that it is not necessary to exercise every day of the week to reap meaningful physical and psychological benefits.
