Smoking causes a marked increase in a person's metabolic rate and tends to reduce their food intake compared with that of non-smokers(footnote 1) . Several studies have reported that people tend to gain weight after they have quit smoking(footnote 2) .
In 2007-08, adult men who were ex-smokers were more likely to be overweight or obese (76%) than current smokers (60%) or those who had never smoked (65%) (Graph 5.2). In particular, men who had quit smoking were more likely to be obese (32%) than those who still smoked (24%) and those who had never smoked (21%). On the other hand, there was no significant difference in the prevalence of obesity for women who were ex-smokers, current smokers or had never smoked.
