A person with a weight of 200 pounds can burn 638 calories every five miles, according to Modern Mom. People with a weight of 160 pounds can lose 510 calories within the same distance. The number of calories lost during a five-mile walk depends on walking time, miles per hour walked and weight.
Modern Mom lays out an extensive walking plan for people of different body types. A person can calculate how many calories lost by multiplying the walking time by the calories lost per minute.
The Mayo Clinic provides a chart that breaks down how many calories are burned walking per hour. A person can further calculate the calories lost per minute by dividing the calories burned per hour by 60 minutes. For instance, Mayo Clinic notes that a person weighing 160 pounds burns 204 calories at a rate of 2 mph when walking. Therefore, a person can divide 204 by 60 to get 3.4 calories lost per minute.
Modern Mom uses the example of a 160 pound person being able to burn 3.4 calories every minute, walking at 2 mph. When figuring out the how long it takes to run for five miles (ex. 150 minutes weekly), a person can multiply 3.4 calories by 150 minutes to get 510 calories burned every five miles. That number is different for a person weighing 200 pounds, walking at 2 mph and burning 4.25 calories per minute. If that person does the same math, 638 calories are burned when walking five miles.
About.com offers a walking calories calculator that determines the number of calories burned based on weight, walking speed and the number of miles. Modern Mom notes that taking in more calories than necessary can replace the number of calories burned for five-mile walking plans. Merging a healthy diet with a walking regimen is necessary.
