Does running every day help you lose weight?

Many people have a habit of jogging in the morning or at night, and thus maintain an ideal weight but running to lose weight becomes more difficult as the years go by, scientists from the University of California report. In one study, researchers discovered that men who ran the same distance every week year after year (regardless of kilometers traveled) gained weight; even those who exceeded 24 kilometers a week.

"Your metabolism gets a little slower every year, so you need to increase your activity levels as time goes by," explains the doctor responsible for the study. "However, most men do the opposite." Additional research suggests that running on a regular basis improves "your body's efficiency in exercising," which means that the same activity burns fewer calories. The researchers calculate that to avoid gaining weight, runners need to increase the mileage they run each week with one kilometer a year.
