No, actually studies show that smokers are more likely to gain weight. A 50-month study of 7,565 people showed that smokers, and even ex-smokers, gain more weight than those who have never smoked. The study also showed that in people who quit smoking during the study, the more cigarettes they smoked before they stopped equaled more weight gain. Those who continued to smoke during the study gained more weight that the non-smokers as well.
