In a study published in the March edition of Journal of American Association, researchers from Switzerland have shown that in non-diabetics, weight gain after quitting smoking does not take away the cardiovascular benefits of quitting smoking.
There is a net cardiovascular benefit of smoking cessation despite subsequent weight gain. Smoking cessation is always beneficial for smokers.
People gain 6-8 pounds of weight after quitting smoking. In the study, quitting smoking was also linked with a decreased risk of heart attack or cardiac death compared to smokers.
