Want to keep the weight off? Get on your bike 想減肥?騎單車吧


Just five minutes of riding a bicycle each day can help a younger woman keep the pounds off, U.S. researchers have reported in a study offering one potentially easy way to help Americans slim down.
The heaviest women benefited the most, the team at the Harvard School of Public Health and Brigham and Women’s Hospital in Boston reported. "Small daily increments in bicycling helped women control their weight. But the more time women spent bicycling, the better," said Harvard’s Rania Mekary, who worked on the study.
"Women with excess weight appeared to benefit the most. This is encouraging for women with weight problems because they could substitute bicycling for slow walking or car driving."
The research could help public policymakers trying to find ways to slow the U.S. obesity epidemic, the researchers wrote in the Archives of Internal Medicine. Two-thirds of U.S. adults are overweight or obese and 16 percent of children and adolescents are overweight.
obese:形容詞,過胖的;肥胖的。obesity則是名詞,例句:Overweight and obesity are closely linked to type 2 diabetes.(過重和肥胖與第二型糖尿病有密切關係。)
substitute︰動詞,取代、代替。Substitue honey for sugar.(用蜂蜜代替糖。),也可做名詞,替代品。
