Question: how many calories does 30 minutes of moderate walking burn?
Answer: At a brisk walking pace, you would burn 100 to 300 calories in 30 minutes (depending on your weight) or 200 to 600 calories in an hour. By walking for 30 minutes or more at a time, some of those calories will be from stored fat. During the first 30 minutes of exercise, your body is burning sugars stored as fuel.
