Walking vs. Running to Lose Weight

“Want to lose weight? Then run, don’t walk,” reported U.S. News & World Report in the April 2013 issue.

When it comes to running vs. walking, the Lawrence Berkeley National Laboratory in California conducted a six year National Walkers’ and Runners’ Health Study. When they compared men and women who increased their walking or running, they found that running expended more energy than walking.

But people who choose to run may be different—they may be more physically fit, for example—than people who choose to walk.

Why Sitting is Bad (And How to Get Off Your Duff)

Sitting for hours on end can hurt more than your back end, say two studies.

British researchers tracked 153 younger and 725 older adults who all had risk factors for diabetes. Each participant wore an accelerometer to measure how much time he or she spent sedentary or engaged in moderate-to-vigorous exercise (like running or brisk walking) for at least a week. The results helped researchers hone in on why sitting is bad for people who are at risk for health problems such as diabetes.
