Do Vapes Have Calories?
Health Guides
If you are tracking calories or managing your weight, you may have wondered whether vaping contributes to your daily intake. The short answer is no — but the full picture is worth understanding, particularly around how nicotine and flavours relate to appetite and weight.

Vapour Is Not Digested — It Does Not Contribute to Caloric Intake
The short answer
Do Vapes Have Calories?
Simple answer
No — vaping does not contribute meaningfully to your caloric intake
E-liquid contains ingredients that technically have caloric values when consumed — vegetable glycerin in particular has calories per gram as a food substance. However when vapour is inhaled, you are not consuming these ingredients in the same way as eating or drinking them. The amounts that reach your system through inhalation are negligible and the route of absorption is different. There is no meaningful caloric contribution from vaping that needs to be counted in a diet. You can vape without tracking it as a food or drink intake.
This article addresses whether vaping contributes to caloric intake. For information about how vaping and nicotine may affect your weight through other mechanisms, see our article on whether vaping makes you gain weight.
What is actually in e-liquid
The Ingredients in E-Liquid and Their Caloric Values
Understanding why vaping does not contribute meaningfully to caloric intake requires understanding what is in e-liquid and how it is processed differently when inhaled versus ingested.
Vegetable Glycerin Has Calories — But Not as Vapour
VG is a polyol derived from plant oils and has a caloric value of approximately 4 calories per gram when consumed as food. It is widely used in food production as a sweetener and humectant. However the amount of VG that enters your bloodstream through vaping is a tiny fraction of what would be consumed orally, the route of absorption is entirely different, and the metabolic processing of inhaled versus ingested VG is not comparable. The caloric content of VG in e-liquid is not relevant to dietary calorie counting for a vaper.
Propylene Glycol — Negligible Caloric Concern
PG is used in various food and pharmaceutical applications and has a small caloric value per gram. As with VG, the amounts absorbed through vaping are too small to contribute meaningfully to caloric intake and the inhalation route does not engage the digestive caloric processing pathway that would make these calories count in any practical dietary sense.
Flavourings — No Caloric Impact
The flavouring concentrates used in e-liquid are present in very small quantities and are not ingested. They contribute no meaningful calories to the vaper's dietary intake. Sweet-tasting flavours do not contain sugar and do not have the caloric content of the foods they imitate. A strawberry-flavoured vape does not deliver the calories of a strawberry.
Nicotine — No Calories, but Affects Weight Indirectly
Nicotine contains no meaningful calories and is present in e-liquid in very small quantities by weight. However nicotine does affect body weight through non-caloric mechanisms: it suppresses appetite and slightly raises metabolic rate. These effects can influence weight in ways that have nothing to do with caloric intake from vaping. This is a separate topic covered in our guide on whether vaping makes you gain weight.
The appetite question
Can Sweet Flavours Affect Your Appetite or Eating Behaviour?
This is a question that comes up among vapers who use dessert or fruit flavours and wonder whether the sweet taste cue might stimulate appetite or cravings for food. Some research on sweet-tasting but non-caloric substances suggests that they can produce a cephalic phase response — essentially, the body prepares for caloric intake in response to the taste signal and when no calories arrive, hunger may increase.
Whether this effect is significant enough to affect actual food intake is debated. The research is mixed and the effect, if real, is likely small. There is no strong evidence that using sweet e-liquid flavours causes meaningful increases in caloric consumption through this mechanism. It remains a topic of ongoing research rather than an established concern.
"This comes up quite often, usually from customers who are dieting and want to know if they need to count their vaping. The answer is no — vapour is not a food and does not contribute to caloric intake in any meaningful sense."

You do not need to count vaping in your calorie tracker
Whether you use a calorie counting app or manual tracking, vaping does not need to be logged as a food or drink. There is no meaningful caloric intake from inhaling vapour.
02
Nicotine may affect your appetite
If you are noticing changes in appetite around your vaping sessions, this is more likely related to nicotine's effect on hunger signals than to any caloric impact of the vapour itself. Nicotine suppresses appetite, so vaping before meals may reduce how hungry you feel.
03
Hydration still matters
While vapour does not add calories, PG can contribute to dehydration if water intake is not maintained. Dehydration can sometimes be mistaken for hunger. Staying well hydrated while vaping is good practice for several reasons, including appetite regulation.
04
Weight changes during nicotine step-down are real
If you are reducing nicotine as part of a diet or health improvement programme, be aware that stepping down nicotine can increase appetite as the appetite-suppressing effect diminishes. This is not caused by caloric intake from vaping but by the change in nicotine's effect on your hunger hormones.
