Live like a city dweller
People who live in cities weigh less than those who live in the suburbs probably because of "incidental walking," says Fugh-Berman. "Those few blocks that you walk to grab lunch or run an errand really do add up," she says. Plus, the daily activity is incorporated into your life so it doesn't feel like exercise. It's easy to do and not like a workout that you can skip or quit altogether. Don't live or work in a city? You can mimic the effect by parking a few blocks away from the drugstore, dry cleaner, or post office. Fugh-Berman says she has a slim friend whose only exercise is using the stairs instead of the elevator to get to his office on the ninth floor. Going up and down once or twice a day gives him a fairly good calorie burn.
