Start a new hobby - Many former smokers realize that they have a lot of time on their hands when they stop their addiction. Starting a new hobby will keep your hands and mind occupied so you are less likely to fill up the time with food, food-related activities or falling back into your smoking habit. Join an art or crafts class, begin a new sport, or just get involved in the local community to stay busy.

Weight gain may seem inevitable when you decide to quit smoking, but there are several ways you can ward off the extra pounds and maintain a healthy lifestyle. A few modifications to your diet, keeping up with an exercise regimen and focusing on positive activities can help you overcome your addiction without gaining a single pound.
