Is there a connection between smoking and waist size? Although some smokers use cigarettes to control their appetite, studies show that, over time, nonsmokers gain less weight than smokers. Heavy smokers are more likely to be overweight or obese than light smokers are. Heavy smokers tend to have a larger waist, which is associated with an excess of abdominal visceral fat. Visceral fat, which surrounds vital organs in the abdomen, is related to metabolic syndrome, diabetes, and cardiovascular diseases. Insulin resistance may be directly increased by smoking.
