What keeps smokers thin

Previous studies have shown that smokers have less body fat as compared to non-smokers. Now, a new study by US researchers may help explain the reason. For the study, researchers from Weill Medical College of Cornell University New York evaluated the levels of alpha2-zinc-glycoprotein1 (AZGP1), a gene linked to weight loss, in 37 healthy nonsmokers and 55 healthy smokers. They found that AZGP1 levels were higher in smokers than nonsmokers.
