You may wonder: Do Vapes Have Calories? The short answer: yes—but the amount is so minuscule it won’t affect your waistline. Let’s explore the facts.
1. Yes, Vapes Contain Trace Calories (But They’re Negligible)
E-liquids consist mainly of propylene glycol (PG) and vegetable glycerin (VG), both of which have around 4 calories per gram. However, when inhaled, almost none of these calories are absorbed. According to both Royal Flush Vape and Edge Vaping, a 10 ml bottle of e-liquid contains roughly 40 calories, and a disposable vape only around 8 calories total—far too little to impact your diet.
2. Inhaling ≠ Consuming: Why You Don’t Gain Weight
Our bodies absorb calories in the digestive system—not through the lungs. Even with sweet flavorings, the aerosol from vaping doesn’t deliver usable energy . So yes, Do Vapes Have Calories technically—but no, you won’t digest them.
3. Nicotine: The Real Influencer on Weight
While calories from vapes don’t matter, nicotine does. It suppresses appetite and increases your resting metabolic rate by about 10%, which can support minor weight loss—or at least prevent the weight gain often seen when quitting smoking batashmedical.com. However, this metabolic boost is modest—perhaps burning ~200 extra calories per day—and not a healthy weight-control strategy .
4. Appetite & Cravings: Behavioral Aspects of Vaping
For many, vaping mimics the hand-to-mouth ritual of eating, distracting from snacking. This behavioral aspect may curb food cravings, but scientific evidence remains inconclusive.
5. Are There Any Calories Per Puff?
Calories per puff are virtually zero. Myster reports about 5 calories per milliliter of vape juice, which breaks down to just 0.05 calories per puff—insignificant in the context of daily intake.
6. Potential Drawbacks & Health Concerns
Even though Do Vapes Have Calories isn’t a dieting worry, vaping carries other risks. Vaping may expose users to harmful chemicals like formaldehyde and acrolein from heating PG/VG, and ingesting flavorings long-term remains poorly understood. Moreover, nicotine addiction, cardiovascular effects, and respiratory concerns remain substantial considerations .
7. Should You Vape to Lose Weight?
Definitely not. While nicotine may slightly boost metabolism and suppress hunger, the health risks of vaping far outweigh any minor benefit. Experts advise against using vaping as a weight-loss tool .
8. Vaping & Fasting or Diet Plans
Because inhaled vape vapor isn’t absorbed as food, it doesn’t break a fast. However, nicotine may increase metabolic rate, possibly affecting hunger levels or insulin responses during fasting.
9. Summary Table

Final Thoughts
Vapes contain negligible calories—far too little to contribute to weight gain. The bigger question isn’t about Do Vapes Have Calories, but about nicotine’s effects: it can modestly suppress appetite and raise metabolism, yet these effects pale in comparison to the health risks of vaping. Decide wisely, prioritize well-being, and consult professionals for weight concerns.
