Do Vapes Have Calories? Unpacking the Truth Beyond the Puff

Quick answer: Vape liquids contain calorie-containing ingredients, but the actual calorie impact from vaping is practically negligible for most people.
Vape liquids typically include propylene glycol, vegetable glycerin, flavorings, and nicotine. While PG and VG have caloric value, the amount absorbed through vaping is tiny compared with daily food intake.

What matters more than calories
| Factor | Why it matters |
|---|---|
| Nicotine effects | Can affect appetite and cravings. |
| Dehydration | PG and VG can dry the mouth and throat. |
| Flavor additives | Long-term inhalation effects vary. |
| Habit replacement | Vaping can replace meals or snacks. |

Nutrition focus if you vape
- Prioritize real meals, not appetite suppression.
- Track hydration, especially if you vape often.
- Keep a consistent food log so trends stay visible.
