Quitting smoking linked to weight gain
NEW YORK (WABC) -- Yale University scientists believed they've figured out why people who give up smoking suddenly pack on the pounds.
In a report in the Journal of Science, they say nicotine is to blame.
It activates a receptor in the region of the brain that controls appetite.
Researchers say it rev up the cells that would ordinarily tell a person to stop eating when they are full.
