“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.
