10. Obey the 1-mile rule
Americans use their cars for two-thirds of all trips that are less than 1 mile and 89% of all trips that are 1 to 2 miles, yet each additional hour you spend driving is associated with a 6% increase in obesity. Burn calories instead of gas by following this rule: If your errands are less than 1 mile away, vow to walk them at a brisk pace instead of driving. Or park where you can run several errands within a mile instead of moving your car each time. Walk every day and you’ll be 13 to 17 pounds lighter next year.
