Do Vapes Have Calories?

Assortment of vape devices with a starburst label reading 'KCAL?'

A common question we get these days is 'do vapes have calories?'. With the rise in sweet fruit and dessert flavours, it's a totally fair question to ask - and one that's becoming increasingly common among vapers. 

In short, yes, vapes do contain calories, but it's a very small amount and not the same as in food or drink. Also, when you vape, the calories are inhaled through your lungs rather than being digested in the stomach where they're broken down and used for energy. The lungs are primarily used for gas exchange rather than digestion. [1]

In this article, we will cover a number of questions, which include how many calories in a vape, how vaping affects your appetite, and how they're absorbed into your body. So let's explore further...

 

Does e-liquid contain calories?

E-liquid does indeed contain calories, but the amount is super low. Vaping calories are processed very differently than food and drink calories. When spread over a matter of days, they contribute very little to your calorie intake. 

Where does it get its calories?

Vape juice gets its calories from its primary ingredients - mainly Vegetable Glycerin (VG), and to a lesser extent, Propylene Glycerin (PG). Both ingredients are commonly used in food products, though when used in vapes, they add very little to energy levels.

 

How many calories in a vape?

As mentioned before, vapes contribute very little to calorie consumption. Most 10ml e-liquid bottles contain 30-50 calories in total, with a single puff offering just 0.05 to 0.25 calories.

Here is a short breakdown of what you can expect from most vapes and e-liquids regarding calorie intake:

  • Prefilled Pod Kits: Most prefilled kits contain a 2ml pod, estimated to carry around 8-12 calories in total.
  • 10ml E-Liquids: These bottles contain around 30-50 calories in total.
  • 50ml E-Liquids: These are estimated to contain between 250-300 calories.
  • 100ml E-Liquids: Usually carrying around 400-500 calories.
  • 200ml E-Liquids: Usually contain around 800-1000 calories.

 

How does the body absorb calories from vaping?

Calories are ingested very differently from vapes when compared to food and drink. As vapour is inhaled, the body doesn't use the calories in the same way. 

When inhaled, vapour passes through the lungs, which are used for gas and oxygen exchange rather than digestion, so vapour calories will not have the effect on weight levels that food or drink will. On the other hand, food and drink are ingested through your stomach, where calories are broken down and used as a source of energy. 

 

Will vaping affect my appetite?

Yes, like smoking, vaping can have an effect on your appetite. Vapes contain nicotine as a primary ingredient which, like food and drink, produces a dopamine hit that gives your brain that 'feel good' feeling. 

With continued vaping, the nicotine can become a mild substitute for the food's dopamine hit, leading to increased vaping and slightly less food consumption. For this same reason, smokers or vapers usually notice an increase in appetite once they've stopped.

While vapes can lower appetite, this is usually pretty mild. For medical reasons, we strongly advise not to rely on vaping as a weight loss method.

 

Do vapes contain sugar?

No, most vapes do not contain sugar. They instead use artificial sweeteners and flavourings for that rich taste you experience. These sweeteners will usually be Sucralose, Erythritol, Ethyl Maltol or Stevia. Read on for a brief look at these sweeteners and what they offer:

  • Sucralose: One of the most commonly used sweeteners in vapes. It's much sweeter than sugar, and gives your vape a rich, punchy flavour.
  • Erythritol: This sweetener isn't as rich as sucralose, and contains around 70% sweetness of sugar. 
  • Ethyl Maltol: Although not a sweetener as such, this flavour-enhancer is used to give the perception of sweetness and is often used in 'cotton candy' flavours.
  • Stevia: Used as a sugar substitute for hundreds of years. Like Sucralose, Stevia is a lot sweeter than sugar but without the same intensity.

 

Conclusion

To round things off, vapes and vape e-liquids contain a mixture of ingredients with a few containing calories. So in answer to the question 'do vapes have calories?' or 'are there calories in vapes?', technically yes, but it is minimal and bears little to no impact on weight, diet or calorie intake. With that considered, I hope this has been helpful and gives you added peace of mind on your vaping journey. If you have any further questions, check out our FAQ section below!

600 puff vapes like the Lost Mary BM600 technically hold around 10-30 calories per 2ml pod. This works out to around 0.05 calories per puff.

Why am I losing weight when vaping?

This could be happening as vapes contain nicotine, which is an appetite suppressant. When you vape, the nicotine gives you a dopamine hit, which with dependence, can lead to less appetite and steady weight loss.
