So start today. Start striving for a healthier lifestyle today. Use the stairs instead of taking the elevator. Ride your bike or walk when you can instead of taking the bus or driving your car. Clean that closet you've been meaning to or clean out the garage.
Hand wash the car instead of driving through the car wash.
Buy a big dog and walk him or her daily. Join a walking club or a gymnasium. The calories you burn during physical activity over the entire day add up. You don't want to overdo it and burn too many calories at one time, especially when you are on a low-calorie diet program. Try to find a friend or family member who will support your efforts.
