How Many Calories Do You Burn by Walking for 45 Minutes?
How many calories you burn depends largely on your weight and level of exertion. Here's an estimate of what you can expect from a 45-minute walk.
Since one pound has the calorie equivalent of 3,500 calories, you would have to walk at 5 mph for five hours and 40 minutes to burn the caloric equivalent of one pound. Even that isn't a reliable marker because the more you weigh, the more calories you burn.
A 120-pound person would burn less calories in the same amount of time, walking at the same speed, as a 200-pound person. Use the American Council on Exercise's physical activity calorie calculator for your exact weight.
