Smoking helps break down body fat?

May 13, 2009 12:00:00 AM PDT
A new study suggests smoking enhances the activity of a gene that helps break down body fat and controls weight gain.Researchers say smoking increases the activity of a gene called AZGP1. Since the gene is believed to play a role in controlling weight, researchers say the gene activity could be a reason why smokers tend to weigh less than non-smokers. In addition, it may explain why smokers tend to pack on the pounds after quitting.

Researchers from Weill Medical College of Cornell University in New York reported their findings in the journal, Chest.

Researchers say those who quit smoking tend to eat more, just as they lose the metabolism boost that nicotine provides.
