Quitting smoking often leads to weight gain.
FOX's Karlie Pouliot explains why in today's "Housecall for Health"...
Yale researchers say they've finally discovered why some people gain weight after kicking the habit.
It turns out that nicotine can "revv up" brain cells that normally signal people to stop eating when they're full. On average, people who kick the habit gain less than 10 pounds, but that's still a big concern. So scientists are now trying to see if this discovery will lead to better treatments to help people quit WITHOUT the worry of weight gain.
