Question: how many calories do you burn walking fast for 20 minutes?
Answer: A 20-minute brisk walk will cover at least one mile. It will burn 70 to 100 calories, depending on your weight. You will add 2000 to 3000 steps to your daily step count. A large study showed that you could reduce your risk of early death by as much as 30 percent with a brisk 20-minute walk each day.
