An hour’s walk at a brisk pace, three to four miles per hour, will burn about 300 calories. Let’s say you sign up for five days per week and make no other change in your exercise or diet. What happens?
If you stick with this you will burn 1,500 calories per week, 78,000 per year; since there are 3,500 calories in a pound that translates into twenty-two pounds. You’ll likely miss a few days due to weather, travel, etc., but you do have a choice — you can do more distance on other days to make up for it.
We recently returned from a trip to the Mideast. One of the members of the group was Carlos, a young man in his thirties. He told me that when he finished college he was very heavy because he’d spent too much time eating and drinking. He started walking thirty minutes a day and in a year he dropped fifty pounds. Remember that he was in his twenties with the high metabolism that goes with that age.
