Increased Bodyweight After Stopping Smoking May Be Due to Changes in Insulin Secretion

Not hardly.

Fear of putting on weight is one of the major reasons why smokers do not give up their habit. The reasons for this weight gain are believed to be in part due to metabolic changes in the body, but until now precise details of these changes were not known. On May 8, 2012, however, a researcher from Austria told delegates at the International Congress of Endocrinology/European Congress of Endocrinology that her work had shown that changes in insulin secretion could be related to weight gain after smoking cessation.

Has nothing to do with insulin.

Has to do with only one thing - more Calories in than out.

Period.
