The average person needs to walk at a 2 mph pace for 257 hours to burn the caloric equivalent of 10 lbs. Luckily, you can exercise over time to promote weight loss.
Calories per Pound
According to the American Council on Exercise, 1 lb of body fat equals 3,500 calories. Therefore, a daily caloric deficit of 500 results in a weekly weight loss of 1 lb. A daily caloric deficit of 1,000 calories results in a weekly weight loss of 2 lbs.
Calories for Ten Pounds
Ten pounds of body weight is equal to 35,000 calories. Burning 500 calories a day, for 70 days, burns 10 lbs worth of calories.
Considerations
The American College of Sports medicine suggests combining exercise and caloric restriction for optimal weight loss results. For example, it may be easier to reach a daily caloric deficit of 500 by burning 250 calories with exercise and cutting 250 dietary calories.
