Quitting smoking doesn't mean you'll automatically gain weight. And even if you do gain a couple pounds, that's not as important as saving your life... and the lives of others. When people gain weight, it's usually because they start to eat more once they quit smoking. If you watch what you eat and stay physically active, you may not gain at all!
Becoming more active can help you reduce or maintain your weight. Try any of the following. Check with your doctor first if you've been inactive a long time or have medical problems, you're middle-aged or older, and you plan a vigorous exercise program.
Walk in your neighborhood or at indoor shopping malls.
Do gardening or yard work.
Take stairs instead of escalators and elevators.
Park farther from stores and walk.
Learn a new dance.
Ride a bicycle.
Try aerobic dance classes or use a videotape at home.
