Study finds why smokers gain weight when they quit

WASHINGTON (AP) - Scientists say they've made a discovery that
might someday take the worry of weight gain out of quitting
smoking.
It turns out that nicotine can rev up brain cells that normally
signal people to stop eating when they're full.
The weight connection isn't huge. On average, quitters gain less
than 10 pounds. Still, it's a worry that many smokers cite when
asked why they don't try to quit. Now the question is whether the
discovery might lead to better treatments to help them quit without
worrying about weight.
Smoking causes cancer, heart attacks and a host of other
ailments so worry about modest weight gain shouldn't deter someone from quitting. Study senior author Marina Picciotto of Yale
University says smokers who do have that concern should try
nicotine-based smoking-cessation treatments.
The research is in the journal Science.
