    Preventing Weight Gain After You Stop Smoking

    Smoking acts as an appetite suppressant, so gaining weight is a common concern for many of us when we decide to give up cigarettes. You may even be using it as a reason not to quit. While its true that many smokers put on weight within six months of stopping smoking, the gain is usually smallabout five pounds on averageand that initial gain decreases over time. Its also important to remember that carrying a few extra pounds for a few months wont hurt your heart as much as smoking does. However, gaining weight is NOT inevitable when you stop smoking.

    Smoking dampens your sense of smell and taste, so after you quit food will often seem more appealing. You may also gain weight if you replace the oral gratification of smoking with eating unhealthy comfort foods. Therefore, its important to find other, healthy ways to deal with unpleasant feelings such as stress, anxiety, or boredom rather than mindless, emotional eating.

    Nurture yourself. Instead of turning to cigarettes or food when you feel stressed, anxious, or depressed, learn new ways to quickly soothe yourself. Listen to uplifting music, play with a pet, or sip a cup of hot tea, for example.

    Eat healthy, varied meals. Eat plenty of fruit, vegetables, and healthy fats. Avoid sugary food, sodas, fried, and convenience food.

    Drink lots of water. Drinking at least six to eight 8 oz. glasses will help you feel full and keep you from eating when youre not hungry. Water will also help flush toxins from your body.

    How Nicotine Hooks You

    Nicotine from tobacco enters your bloodstream through your lungs. From there, it travels to the brain,flooding its reward circuits with a chemical known as dopamine . This explains thehigh that smokers feel whenever they smoke.

    The problem is that the effects of nicotine wear off after a few minutes, causing the smoker to long forthe feeling again. This leads to a vicious cycle of smoking so that the high can be felt again.

    Your body tends to adapt to the amount of nicotine in your bloodstream. As your tolerance increases, thenumber of cigarettes you need to smoke in order to get the same high will also increase leading to afull-blown addiction.

    Genetics Of Nicotine Addiction

    Studies in twins have shown a high degree of heritability of cigarette smoking , including the level of dependence and the number of cigarettes smoked daily. These studies have also revealed the heritability of the particular symptoms that occur when a smoker stops smoking.

    Numerous attempts have been made to identify genes underlying nicotine addiction. Such studies are problematic because multiple genes and environmental factors determine complex behavior, and the many different dependence phenotypes may have different genetic underpinnings. Candidate genes coding for nicotine-receptor subtypes, dopamine receptors and dopamine transporters, GABA receptors, opiate and cannabinoid receptors, and other types of receptors have been associated with different aspects of smoking behavior. Subsequent research, however, has not replicated many of the initial findings.

    How Nicotine Causes Addiction

    Nicotine causes addiction by causing chemical changes in the brain. Using nicotine-containing products, including smoking cigarettes or vaping, causes the release of a chemical in the brain called dopamine.

    Dopamine trains people to act a certain way by reinforcing certain behaviors. It does this by rewarding a person with a pleasurable sensation. This is called reinforcement. Each time a person takes a puff on a cigarette or vapes, they get a dopamine hit. This causes them to use nicotine-containing products over and over.

    How Is Tobacco Addiction Treated

    The good news is that treatments for tobacco addiction do work. Although some people who smoke can quit without help, many people need help. Behavioral treatment programs help people learn about and change their behaviors using self-help materials, counselor-staffed telephone “quitlines,” and individual therapy. Over-the-counter medications, such as the nicotine patch, gum, inhalers, and lozenges, replace nicotine and relieve the symptoms of withdrawal. It is important to know that nicotine replacement medicines can be safely used as a medication when taken properly. They have lower overall nicotine levels than tobacco and they have little abuse potential since they do not produce the pleasurable effects of tobacco products. They also don’t contain the carcinogens and gases found in tobacco smoke, making them a good treatment approach for quitting.

    There are also prescription medications now available for smoking cessation, such as bupropion and varenicline tartrate , that have been shown to help people quit. But research shows that the most effective way to quit smoking is to use both medications and behavioral treatment programs.
