Average Weight For Age Groups

Lose Weight Via Exercise

To lose weight one must burning more calories through activity than one consumes. That means either exercise more, eat less, or do a combination of both. Running and walking are both good exercises that can help control weight and improve cardiovascular fitness.

Calories Burned Running

Ralph LaForge of the Duke University Medical Center provides a detailed analysis of the net caloric requirements of running and walking. He defines the net caloric requirements as the calories required beyond what the body would burn if one had remained sedentary. (Technical detail: The calories used here are food calories, which are 1000 of the calories used in physics and chemistry.)

A person running burns calories at a net rate of 1.53 calories per kilogram of body mass per mile. That corresponds to 70 calories per mile for every 100 pounds of body weight. A 150 pound person will burn just over 100 calories per mile, and a 200 pound person will burn about 140 calories per mile of running. To compute how many calories you will burn running a mile, multiply your body weight (in pounds) by 70 and divide by 100.
