Actually, quitting smoking was the whole reason I started losing weight. When I had cravings, exercise was the only thing that made them go away. I never had the desire to exercise before I quit smoking. Normally, when I was stressed, I would smoke. I realized going for a run or bike worked just as well, and I was actually prolonging my life instead of cutting it short.
At one point, I DID start smoking again, partially because I was afraid of gaining and thought i would lose weight faster. I only smoked for two week sbefore I stopped because I realized how much of an impact of it was having on my weight loss in a negative way. I was working out less, for shorter periods of time, in less intense sessions.. because I couldn't breathe through them! I actually gained 3 pounds while I was smoking. So quitting smoking actually effected my weight loss positively.
Although smoking has a VERY slight boost on the metabolism, that's not the reason most people gain weight while quitting. Smokers depend on an outside force to make them feel better. Many people feel the need to have a 'thing' that makes them feel better. Some people drink, some do drugs, some people smoke, and some eat. All the same thing. Removing cigarettes can make someone feel like an emotional eater, which will cause them to gain weight. Emotional eating is something you can control, so yes, you can quit smoking without gaining weight.
The ONLY reason I have been succsessful with my weight loss is because I stopped smoking. There are physical reasons, sure: increased energy and stamina. But the real reason quitting smoking was ABSOLUTELY NECESSARY for me was because of what it gave me mentally. It made me realize that I had to be in charge of how I was feeling and stop depending on something to make me feel better - including food. I no longer am an emotional eater like I was before I quit smoking. Quitting also made me realize that I was capable of accomplishing goals I set for myself, something I needed to be successful at losing weight. I've already met my first mini-goal of 150 lbs.
There is a reason why, as a smoker, I always yo-yo dieted and never managed to stay on track! If you are thinking about quitting DO IT, it will only make your weight loss easier and more enjoyable!
