Weight gain is very common after quitting smoking, especially in the first few months, but it is not inevitable.
Nicotin, a substance in tobacco, suppresses appetite and can slightly increase metabolism. Therefore, once you quit smoking, your appetite and metabolism levels return to normal, meaning you may eat more and burn fewer calories. Additionally, quitting smoking improves your sense of taste, making food more tempting, which can lead to increased food intake. Moreover, if you replace smoking with snacking after quitting, your calorie intake will significantly increase.
To avoid weight gain after quitting smoking, diet and exercise should be part of your quitting plan. Additionally, remember: the health benefits of quitting smoking far outweigh any weight gain issues. The lung disease and heart disease caused by smoking are irreversible, while weight gain is reversible.
