Food per kilometer

Surprisingly, how fast a person runs has little effect on the number of calories he or she will burn. The most important factor is weight. For example, a 220-pound person running an eight-minute mile burns 150 calories, while a 120-pound person running at the same pace burns only 82. Every person’s body requires an excess of 3500 calories in order to gain a pound or a deficit of 3500 calories in order to lose a pound. Thus, 180-pound person who runs 5 miles each day will lose about 5 pounds a month. However, as his or her weight goes down, he or she will burn fewer calories per mile. Eventually, a runner’s weight will stabilize. When this will happen depends on how much the runner eats and how far he or she runs. Most runners lose weight effortlessly at first, but eventually, their weight stops declining and reaches a plateau. In order to continue to lose weight, some serious runners will intensify their workouts, as extra weight will only slow them down. Otherwise, recreational runners can maintain their lower body weight by continuing to run consistently.
