The average smoker would have to gain about 125 pounds to run the same health risk as smoking a pack of cigarettes per day. Smoking is not a healthy way to control weight, even though it changes the way your body uses food. Once food leaves your stomach, nicotine moves the food through your digestive tract faster. Because of this, your body doesn't get as much nutrition. Nicotine may speed up metabolism, causing your body to burn more calories and store less fat.
Smoking decreases the appetite for sweets, and is often used to replace dessert.
Here are some hints to help prevent weight gain. Not all of these ideas are for everyone, but the more you use, the greater your chances of controlling your weight while quitting smoking. Eat well-balanced meals regularly. Choose a healthy, balanced eating plan you can stick with. Don't eat more than you need.
