To use the above, simply multiply your weight (in pounds) by the number shown. For example, if you weigh 188 lbs, you will burn about 107 calories (188 * .57) when you walk a mile, and about 135 calories (188 * .72) when you run a mile.

As you can see, running a mile burns roughly 26 percent more calories than walking a mile. Running a minute (or 30 minutes, or an hour, etc.) burns roughly 2.3 times more calories than the same total time spent walking.

Okay, now a few caveats. These calculations are all derived from an “average” weight of the subjects; there may be individual variations. Also, age and gender make a difference, though quite a modest one. Your weight is by far the biggest determinant of your calorie burn per mile. When you look at per-minute burn, your pace (your speed) also makes a big difference.

These calculations aren't meant to be precise. They are good approximations, and much more accurate than the old chestnut: You burn 100 calories per mile.

Walking a mile does not burn as many calories as running a mile.

Reading any tables of calories burned per minute for any activity is sobering. Running only burns 11 to 16 calories a minute. The painful truth is that modern society provides many fast and easy ways to add calories but few ways to burn them off quickly.

The age of surplus: we are drowning in both information and food.
