One pound of body fat is equivalent to 3500 calories. On average, it will take about 10,000 steps a day, more or less, to get in five miles of walking. At that rate, if your target weight loss goal is 35 pounds, it will take approximately one week to lose a pound or two.
Nothing beats a pedometer as a reality check on how much you actually are moving throughout the day. For weight loss, first see how many steps you walk in a typical day. Then set a goal of 2,000 more steps per day than that average number. Check your pedometer frequently during the day to stay on target and look for opportunities to get in more steps.
