How Many Calories Are in a Vape? The Definitive 2025 Guide

1. Introduction: Why People Even Ask This

Vaping is often seen as an alternative to smoking, but when health awareness is high, many users begin asking questions beyond nicotine: Does vaping “feed” you calories? Could it affect weight gain?

While traditional foods and drinks deliver calories your body absorbs, vaping most likely will not meaningfully impact caloric intake. However, understanding how vape juice is composed helps clarify where the question arises.

2. What Makes Up Vape Juice & Where Calories Could Come From

To estimate calories, we need to dissect what’s inside vape juice (a.k.a. e-liquid). According to multiple sources, typical vape juice consists of:

Because the bulk of vape juice is VG + PG, those base liquids are where “calorie potential” comes from. But that’s not the full story.

3. How Many Calories Are Actually in Vape Juice?

Broad Estimates

• Many sources report ~4–5 calories per milliliter of e-liquid (VG + PG dominance). 

• Factoring flavorings and additives, most realistic blends fall somewhere within that same ballpark. 

• For example, GoldenVape’s blog suggests about 5 cals per 1 mL.

What That Means in Practice

• A 2 mL disposable vape might contain ~8–10 calories of e-liquid.

• Some sources say a 10 mL e-liquid bottle might be ~40 calories total. 

• Another source claims 100 puffs per mL, so each puff has ~0.05 calories (i.e. insignificant). 

Hence, while “vapes have calories” is technically true, the amount is extremely small relative to daily caloric intake.

4. Can Your Body Absorb Those Vape Calories?

This is the critical point: no, not in any meaningful way.

• Calories are absorbed via the digestive system (stomach, intestines). Inhalation doesn’t route substances into that system. 

• Some vapor may condense in the mouth or throat and trickle down, but that volume is minuscule—too small to meaningfully affect caloric intake. 

• As Innokin’s blog puts it: even though vape juice contains ~5 cal/mL, you don’t “absorb calories by inhaling.” 

In other words, your body doesn’t treat vapor like food.

5. Does Vaping Lead to Weight Gain or Loss?

Given the above, the consensus is:

• Calories from vaping are not a driver of weight gain. 

• If anything, nicotine’s effect (in vapes that contain it) is to suppress appetite, potentially leading to reduced food intake (though that’s a separate, more complex metabolic effect). Ciliconplus+2Vape Juice+2

• Vaping itself does not burn calories—there’s no physical exertion involved. Royal Flush Vape+1

• People who begin vaping sometimes mistake behavioral changes (e.g. replacing snacks with puffing) for metabolic effects—but the direct caloric effect is negligible.

So, if someone gains weight after starting vaping, it is extremely unlikely to be caused by “calories from the vape.”

6. Why This Myth Persists

• The term “juice” or “liquid” sounds food-like, confusing some readers.

• The idea that anything “ingested” (even as vapor) might add to calorie count is intuitive but scientifically incorrect.

• Some blogs or vendors overstate calorie claims to attract attention.

• Misunderstandings around nicotine, metabolism, and appetite also blur the lines.

By clarifying that calories must pass through the digestive tract to count, you help dispel the myth.

7. Sample Calculations & Scenarios

Let’s run a few hypothetical numbers to illustrate how minimal vape calories are in real life:

In context: a slice of bread has ~80–100 calories. Vaping a whole disposable may be less than 10% of that—but since you don’t absorb it, the effect is practically zero.

8. SEO-Optimized FAQ Section

Below is a set of FAQ entries structured for potential Google rich snippets. Use these in your HTML (or CMS) as a FAQ block or structured data.

Q1: Does vaping have calories?
Yes — vape juice (VG + PG) carries a small caloric content, typically ~4–5 calories per milliliter. But because you inhale rather than ingest, your body doesn’t absorb most of them.

Q2: How many calories are in a vape?
Roughly 5 calories per mL of e-liquid. So a 2 mL disposable has about 10 calories of liquid content.

Q3: Do we absorb calories from vaping?
No. The digestive system absorbs calories—not the lungs. Vapor doesn’t travel through your digestive tract.

Q4: Can vaping cause weight gain?
No, not from the calories themselves. Vaping’s caloric effect is essentially negligible.

Q5: Does nicotine in vape affect appetite?
Yes, nicotine may suppress appetite in some users, but that’s a metabolic effect distinct from caloric intake.

Q6: How many calories per puff?
If 1 mL yields ~100 puffs, each puff is ~0.05 calories—nearly zero.

Q7: Are flavored vapes higher in calories?
Flavorings are minor ingredients and don’t meaningfully add calories. Most of the caloric load comes from PG/VG.
