Many ex-smokers report gaining weight after quitting smoking. The average weight gain for people who’ve stopped smoking is between 6-8 pounds (3-4kg) in the year after they quit.
However, if you watch your diet after quitting and ensure that you exercise enough you can prevent weight gain from quitting smoking.
