How to Manage Weight Gain After Quitting Smoking

Why Do You Gain Weight When You Quit Smoking?

It is completely normal to experience some weight gain when you stop smoking.² On average, people typically gain between 1 kilogram and 10 kilograms (2 to 22 pounds) after quitting smoking.²

There are a variety of reasons why people who quit experience a rise in their weight. Below we will explore some of the possible reasons and how to combat them.

Changes in metabolism

When people smoke cigarettes, nicotine (which is the addictive substance in tobacco) makes our body's food processing system work faster which in turn burns more kilojoules.³ When nicotine is no longer present, our food processing system, a.k.a metabolism, slows down.³

This is one major cause why ex-smokers may experience weight gain when they quit smoking even if they do not consume more food than they normally would.³

Changes in eating habits

Many people report that they eat more food once they quit smoking cigarettes.³ Some may experience hunger as a withdrawal symptom once they quit and therefore consume more calories than they were previously.³

It is important to note that research shows that eating patterns will eventually return to normal and this increase in hunger will subside as your body adjusts.³

Changes in taste perception that cause an increase in appetite

It is reported that people who smoke cigarettes have a greater "bitter taste perception" meaning they are more likely to interpret foods and flavours as bitter.⁴ When a person quits smoking, it is possible for their taste perception to return to normal and thus cause an increase in appetite.⁴ This could be due to foods tasting better than they did previously.

Turning to snacks to replace the hand-to-mouth action of smoking

Smoking is not only an addiction, but it is also a physical habit, and like any habit it's hard to break. The physical act of bringing your hand to mouth can easily be replicated with food which is why some people who quit smoking find themselves eating more than they normally would.⁵

Keeping your hands busy is a great way to avoid reaching for food when experiencing cravings.⁵ Consider taking up a new hobby like knitting or instead of snacking, drinking water or herbal tea as a substitute.

Emotional eating due to stress

When you feel a craving coming on, distracting yourself with food is a common habit that people will build to decrease their withdrawal symptoms in the moment.⁵ Typically, the craving will only last a few minutes and it is important to remember that before you grab a snack to distract yourself.⁵

Try distracting yourself for a few minutes during a craving before grabbing something to eat. You may notice this will help decrease weight gain.

NICORETTE^® Smoking Cessation Gum and NICORETTE^® Smoking Cessation Lozenge may help relieve some cravings and decrease the urge to smoke during the stressful first few days of quitting. Consult your doctor if you are wondering if these products are right for you.

5. Limiting alcohol intake

Consuming alcohol can lead to an increase in weight gain because of the calories and sugars present in many alcoholic beverages but it can also make you more likely to smoke.⁵

Try not to drink for the first few weeks after you stop smoking to decrease the likelihood of having a cigarette.

6. Sleeping Well

Getting a good night’s sleep is the first step to improving overall health and well-being. Getting less than 7 hours of sleep has been associated with an array of health problems including weight gain.⁸

Having a healthy sleep schedule is important for maintaining your weight and decreasing the likelihood of poor health.⁸
