Eli5: why does quitting cigarettes cause weight gain?

371 viewsBiologyOther

Many people experience weight gain after quitting smoking, I’m not really sure why. I get that nicotine is an appetite suppressant so people may tend to over eat after quitting but does the weight gain have any other metabolic causes? Will a smoker gain weight if they quit and still maintain the same calorie intake as before?

A lot of the “addiction” to cigarettes is more routine than a chemical addiction the chemicals wear off fairly rapidly, but there is a physical need to be doing something with the hands etc. so often people eat sweets, biscuits etc. where they would normally be smoking.
