DEAR DOCTOR K: I want to quit smoking, but I'm worried about gaining weight. Is it possible to quit smoking without packing on the pounds?
DEAR READER: Smokers do tend to gain some weight when they quit. Why? Nicotine reduces appetite and revs up metabolism (the rate at which the body burns food). Breaking free of nicotine allows appetite to come back and also slows metabolism. In addition, many people substitute food for cigarettes when they quit. By definition, an unhealthy weight is not good for your health. But quitting smoking is good for a person's health.
