Once people who depend on tobacco stop smoking, they may have a series of withdrawal symptoms, such as craving, anxiety, depression and headache. Quitters sometimes mistake the feeling of wanting to smoke for hunger.
Many people begin to take unhealthy measures to deal with withdrawal symptoms, such as eating a lot of high-calorie snacks, which may lead to weight gain.
On the other hand, the withdrawal symptoms of smokers will lead to psychological stress such as anxiety and depression, which may lead to pathological weight gain.
