Because nicotine suppresses the appetite and stimulates the metabolism, quitting smoking may lead to weight gain. Researchers attempted to determine if the obesity epidemic was caused by the decline in smoking.
The study found that quitting smoking led to an average weight gain of 11 to 12 pounds, which lasted for at least 5 years.
They concluded that quitting smoking accounts for 14% of the rise in obesity rates.
However, the researchers found that the skinniest smokers gained the most weight after quitting, which doesn’t necessarily put them in the obese or even overweight category.
Regardless, tobacco smoke kills nearly half a million people each year whereas obesity-related diseases kill just over 100,000.
Yes, quitting smoking may make you gain a few pounds, but it will also add some years to your life.
