Find a Substitute

• Start chewing Nicorette, a gum that is a nicotine substitute for people who quit smoking. Nicorette has many of the same characteristics as nicotine, which speeds your metabolism. It may act as a temporary appetite suppressant as you quit smoking cigarettes.
  
  

Start Exercising

• Live an active lifestyle. This will help prevent you from sitting around and grazing on snacks and junk foods. Spend at least 30 minutes of your day exercising. Walking, biking, running, and lifting weights will burn calories and decrease your cravings for nicotine. People who don't follow an exercise program after quitting smoking are the ones who tend to gain weight.
  
  

Healthy Foods

• Eat fruits and vegetables when you are hungry, and you can also have some sugarless candy from time to time. If you don't eat healthy foods and instead chow down on high-calorie items, such as donuts and cake, you likely will gain weight. The ex-smoker can benefit from keeping his mouth busy after putting a cigarette in it from 10 to 40 times per day.
