It is normal for people to gain weight after giving up smoking. But due to this reason people should not stop themselves from quitting smoking as giving up this habit will help to lead a healthier life with less health problems. People who are usually smoking for 10 to 20 years are more inclined to gain weight. This weight gain can be avoided by eating healthy foods and doing regular exercises. The absence of nicotine which is a chemical compound present in cigarettes from one’s life causes the individual to gain body weight. This is because smoking tends to burn extra calories in the human body. This in turn increases a person’s rate of metabolism. Nicotine is an appetite suppressant which helps in decreasing a person’s appetite. It also acts as a stimulant by reducing the discharge of certain hormones which activate the feelings of hunger. For individuals who are in the process of giving up smoking, food is often used as a substitute to fill the gap caused due to quitting. Moreover the consumption of alcohol during this period increases calories in the human body at a remarkable rate. Thus to prevent this one needs to control his or her alcohol intake. Moreover regular exercises also help in reducing the extra weight.
