Tobacco and weight gain: sorting out fact from fiction

The fear of gaining weight sometimes prevents you from quitting smoking. The reality is more nuanced, and above all, weight gain can be controlled.

“I would stop, but I'm afraid of gaining weight. » This fear is one of the main obstacles to quitting smoking, particularly among women. What is it really? While weight gain is possible, it is neither systematic nor inevitable, and above all, its benefits are out of proportion to its risks. Let's sort out the truth from the fiction.

1. Why weight can vary

When stopping, several factors can promote weight gain: nicotine had a slight appetite suppressant effect and slightly increased energy expenditure, taste and smell return, and you can compensate for the lack by snacking. These effects are real but manageable.

2. What is true, what is exaggerated

IdeaReality
“We're definitely getting bigger"No, it's not systematic
“The catch is huge”Often moderate, variable
“It's irreversible”No, this can be controlled
“Better keep going"False, the benefits exceed the risk

Any weight gain is on average moderate and very variable. Some people don't gain weight. Above all, the health benefits of stopping far outweigh the risk linked to a few kilos.

3. Limit weight gain

Some strategies help: maintaining physical activity (which also helps manage cravings), taking care of your diet, having healthy alternatives to snacking, and staying well hydrated. Nicotine replacements can also reduce weight gain.

    • Move more, which also helps against cravings
    • Provide healthy alternatives to snacking
    • Take care of your diet and hydrate well

4. Don’t give up for this reason

The fear of gaining weight should not prevent you from quitting: the health benefits are immense. It is also advisable to first concentrate on stopping, then, once this is consolidated, to manage the weight if necessary. Wanting to do everything at the same time can make stopping difficult.

Support from a professional helps you quit while calmly managing your weight.
