Walking is a great exercise for cardiovascular fitness and weight loss. One pound of body fat equals 3,500 calories, so every time you burn 3,500 calories through walking, you are keeping an extra pound at bay.
Average
The rule of thumb is that a person, on average, burns 100 calories a mile when walking. Fast walking and varying terrain will alter this average.
Terrain
For a person weighing 150 pounds, walking 3.5 miles on level ground in 1 hour and 10 minutes burns 302 calories. Walking 3.5 miles uphill in 1 hour and 10 minutes will burn 476 calories. Terrain changes your level of exertion, and therefore the number of calories burned.
Weight
The more you weigh, the more calories you will burn. A 150-pound person walking 2 miles in 40 minutes burns 113 calories, whereas a 200-pound person walking 2 miles in 40 minutes burns 151 calories.
Tools
You can buy pedometers with a calorie-counting function. Additionally, the Internet offers calculators that enable you to input your weight and time to learn the number of calories burned walking.
