Does Vaping Help with Weight Loss? What the Research Says

The idea that vaping might help you lose weight has gained traction in recent years, especially among young adults. But is it really effective  or just another myth?

The Role of Nicotine

Nicotine, the addictive substance found in most vapes, is known to suppress appetite and slightly increase metabolism. Studies suggest it activates parts of the brain that control hunger and energy use, which can lead to eating less and burning slightly more calories. [Read more]

But here's the catch: this effect is modest and not a sustainable or healthy weight-loss solution.

Vaping vs. Smoking and Weight Gain

Many people gain weight after quitting smoking  which is often blamed on the loss of nicotine’s appetite suppressing effect. So some turn to vaping, hoping to avoid this. A systematic review of studies found that people who used e-cigarettes after quitting still gained weight, just like those who quit without them.

In short: vaping didn’t really stop the weight gain.

Why Some People Still Try It

Surveys show that a small percentage of people, especially teens and young adults, use vapes specifically to avoid eating or control their weight. This is especially common among women concerned with body image. [Read More]

But using vaping to manage weight has been linked with disordered eating patterns  a serious concern raised by mental health professionals.

The Health Risks

Using vapes as a diet tool carries serious risks:

Nicotine addiction

Heart and lung damage

Poor nutrition and skipped meals

Increased risk of eating disorders

The CDC and other health organizations strongly warn against using e-cigarettes for weight control.

Common Questions

Does vaping make you fat or skinny?

Vaping doesn't directly cause weight gain or loss. While nicotine can suppress appetite, leading some to eat less, it's not a reliable or healthy method for weight control.

How fast does vaping make you lose weight?

There's no concrete evidence to suggest that vaping leads to significant weight loss, let alone quickly. Any minor effects from nicotine are short-term and not substantial enough to be considered effective for weight loss.

 Vaping and weight loss: What does Reddit say?

Some Reddit users have shared personal experiences about vaping and weight loss. However, these are anecdotal accounts and should be approached with caution.

What to Do Instead
If you're trying to lose weight, go for methods that are safe, healthy, and sustainable — like balanced eating, daily movement, and stress management. If emotional eating is the issue, support from a professional can make a world of difference.
