On average, people who quit smoking gain about 10 pounds according to the World Heart Federation. Weight gain while quitting smoking can be traced to two factors.
First, you eat more. If you’re not smoking, you want to put something else in your mouth. Since you now can smell and taste food better, things like sugary and sweet foods become very attractive.
The second reason is metabolic. “Nicotine increases the metabolic rate. When you stop smoking, your metabolic rate decreases, making you gain weight.
One of the best ways to avoid weight gain while quitting smoking is to exercise. When you stop smoking, you can breathe better, walk better, run better. Take advantage of that.
Exercise also has the additional benefit of helping you burn off the nervous energy many smokers struggle with when they quit. Studies show that people who exercise while quitting smoking gain much less weight, and are twice as likely to kick the habit as those who don’t.
