Do a Little, Get a Lot

Do a Little, Get a Lot
The notion that good health can come in small tidbits is not really new. Research showing that making small changes can add up to a big difference has been quietly accumulating for a while. For example, a study published in the Archives of Internal Medicine in 2004 found that adding just 30 minutes of walking per day was enough to prevent weight gain and encourage moderate weight loss. And if 30 minutes is still too big a bite? Another study, published in Medicine & Science in Sports & Exercise, found that three brisk 10-minute walks per day were as effective as a daily 30-minute walk in decreasing risk factors for heart disease. "Just the act of going from sedentary to moderately active gives you the greatest reduction in your risks," says Helene Glassberg, MD, director of the Preventive Cardiology and Lipid Center at the Temple University School of Medicine in Philadelphia.
