It’s well established that smoking cigarettes can suppress appetite and spur weight loss. But does vaping offer the same effects? With rising obesity rates and growing interest in vaping, many wonder if e-cigarettes could support weight control.
Research on this question shows mixed results so far. While nicotine may curb hunger for some vapers, evidence that vaping reliably causes weight loss is still lacking.
How Might Vaping Influence Weight?
Most vaping devices heat liquid containing nicotine, the addictive chemical also found in tobacco. Nicotine could theoretically promote weight loss in a couple key ways:
Appetite Suppression – By impacting hunger signals in the brain involving neuropeptide Y (NPY) and pro-opiomelanocortin (POMC), nicotine may dull appetite and decrease food intake.
Behavioral Substitution – The physical motions and oral sensation of vaping may replace snacking behaviors, leading to reduced calories.
So for those using nicotine e-liquids, vaping might mimic cigarettes’ weight management effects. But non-nicotine vapes would rely solely on behavioral mechanisms.
The Evidence For and Against Vaping for Weight Loss
Supporting Evidence
Some research does connect vaping to appetite and weight changes:
- A 2016 study found 13.5% of adult vapers used e-cigarettes to control their weight. This group tended to vape more heavily and have weight concerns.
- One 2022 CBD vaping study showed over 70% of trials resulted in decreased appetite and body weight.
Mixed Evidence
However, many other studies present conflicting or uncertain conclusions:
- A 2021 review of in vitro, animal and human research showed inconsistent findings on vaping’s link to weight loss across different types of studies.
- Population data suggests a correlation between declining smoking rates and rising obesity prevalence. But similar clear connections to vaping are lacking so far.
Limitations
- Most existing research relies on self-reported data, which can be biased and inaccurate around sensitive topics like weight.
- Studies rarely account for differences between nicotine versus non-nicotine vaping, which likely influence weight effects.
So while some evidence points to vaping assisting with appetite and weight control, overall data remains mixed and inconclusive.
Vaping Likely An Unreliable Weight Loss Method
With still-limited evidence, depending on vaping alone to lose weight or prevent weight gain seems unwise for several reasons:
Uncertain Efficacy – Too few quality studies document vaping triggering clinically significant weight changes for most people.
Health Risks Outweigh Benefits – Potential cardiovascular, lung and oral health risks associated with vaping likely override unproven weight loss assistance.
Promotes Nicotine Addiction – Encouraging long-term vaping solely for weight management inappropriately cultivates chemical dependency.
Healthier Alternatives For Managing Your Weight
Rather than vaping to lose pounds or avoid weight gain after quitting cigarettes, experts recommend safer evidence-based strategies like:
- Eating more fruits, vegetables, fiber and lean proteins
- Restricting processed foods and refined sugars
- Engaging in regular cardio and strength-training workouts
- Controlling portions sizes based on hunger/fullness cues
- Joining weight loss support communities
Non-vaping options have clearly shown superior weight loss results over time. They also nurture overall physical health rather than undermine it.
Quitting Vaping Poses Some Weight Gain Risks
Just as quitting smoking often spurs initial weight gain, early research suggests stopping vaping may also increase pounds after dependency forms.
Potential drivers include:
- Rebounding appetite
- Oral fixation shifts back to eating
- Metabolic changes
Still, one 2022 animal study found less weight gain occurred after ceasing vaping compared to quitting smoking. So vaping may carry lower risks of post-cessation weight spikes than tobacco cigarettes.
The Takeaway – Vaping for Weight Loss Not Recommended
Despite scattered evidence that vaping could aid weight management, current data remains too sparse and inconclusive to endorse this application.
Given healthier alternatives and the many unknowns around long-term vaping consequences, relying on e-cigarettes to lose weight seems unwise for most people. More rigorous clinical trials in humans are still needed to clarify if nicotine or non-nicotine vaping formulas might hold a place supporting healthy, sustainable weight control.
