Alright, let’s dive into this thing about how many calories are in vapes. I’ve been curious about it for a while, so I decided to do a little digging and some testing myself to figure it out.
First off, I grabbed a few different kinds of e-liquids. You know, the usual stuff you put in your vape. Some were fruity, some were more like dessert flavors. I also checked the labels to see what was in them – mostly propylene glycol (PG) and vegetable glycerin (VG). These are the base ingredients that make the vapor.

Then, I started looking up how many calories these ingredients have. From what I found, both PG and VG have around 4 calories per gram. Sounds simple enough, right? But then I thought, how much of this stuff is actually in each puff? And do we even absorb all those calories when we vape?
So, I went a bit deeper. I found some sources saying that a typical 1 ml of e-liquid might have roughly 1.2 to 5 calories. I decided to use my own vape and measure it out. I filled up a 10ml bottle and started counting puffs. It was a bit tedious, but I wanted to get a real feel for it. After a few days, I calculated how many puffs I got out of that 10ml bottle.
- Day 1: Filled up a 10ml bottle with a mixed berry e-liquid. Took about 200 puffs throughout the day. Noticed the liquid level dropped by about 2ml.
- Day 2: Continued with the same bottle. Took another 250 puffs or so. The liquid level was down to about 5ml.
- Day 3: Still going with the same bottle. Another 200 puffs. Liquid level was around 3ml.
- Day 4: Finished off the bottle with about 150 more puffs. So, a total of around 800 puffs for 10ml.
Based on this, I figured each puff is a tiny fraction of a milliliter. If 1 ml has around 1.2 to 5 calories, then each puff is practically nothing, calorie-wise. But here’s the kicker – I read that our bodies don’t really absorb calories from vaping the same way they do from eating food. It’s like, most of it just goes in and out with the vapor.
Conclusion Time
From all this, I realized that the calories in vapes are super minimal. We’re talking a few calories per milliliter, and each puff is just a tiny bit of that. Plus, our bodies aren’t really taking in those calories anyway. So, if you’re vaping, the calorie thing is probably the least of your worries. It’s way less than what you’d get from a snack or a drink. Just thought I’d share my little experiment and what I learned. Hope it clears things up a bit!
