Don’t let the idea of a slower metabolism keep you from quitting smoking. Let’s look at ways to help your body adjust while it heals.

It’s common for people to gain weight after quitting smoking. In the month after giving up smoking, people gain an average of between 5–10 pounds. This can happen for a variety of reasons, including the physical effects of quitting nicotine.

But there are things you can do to counteract this, such as eating balanced and nutritious meals, exercising, and getting extra hydration as you quit.

There are several reasons people gain weight after giving up smoking. Nicotine affects your body in multiple ways. This means that when you quit smoking, it takes your body time to adjust to not having nicotine.

For instance, according to a 2011 study, nicotine speeds up your metabolism by an average of about 10% when you’re at rest. When you stop smoking, your body might burn calories at a slower rate than you’re used to, leading to weight gain. Smoking can also lower your appetite. Many people feel hungrier when they quit, something else that can lead to weight gain.

Additionally, smoking is a habit. Most people who smoke have multiple cigarettes throughout the day. It’s common for people who stop smoking to reach for a snack as a way to beat cigarette cravings and oral fixation. This is another factor that can lead to excess calories and weight gain.

The weight gain after smoking can be temporary. It can also be minimal. It depends on several factors, some of which you can control.

A study from 2011 indicates that most are hungrier when they first quit smoking, but this is largely a withdrawal symptom that fades after a few months. Tracking your eating habits, along with taking steps such as ensuring you’re getting enough physical activity, can help control weight gain. It can also help you reduce any weight you gain immediately after quitting.

Some people experience constipation, gas, bloating, and other digestive symptoms when they quit smoking. This is typically a result of your body adjusting to not having nicotine. For most people, bloating lasts for a few weeks and then fades. If it lasts longer than a few weeks, it’s important to let a doctor know.
