However, walking is an excellent long-term weight-loss exercise. You can easily walk thousands of miles over decades, because walking has a very low injury risk. How many calories you burn on a one-mile walk depends on your speed and weight.
A 160-lb. person who walks only 35 minutes daily for 15 years weighs 18 fewer lbs. than a nonwalker, according to Harvard Men's Health Watch. Distance walking can help you lose more weight in less time. Walking 4 mph for an hour burns 334 calories, or slightly less than one-tenth of a pound if you weigh 155 lbs. Consequently, you can lose almost 18 lbs. in one year if you walked 4 miles almost every other day, or 180 times, during a year.
