Vaping, a popular alternative to traditional smoking, has raised numerous health-related questions. Among these are concerns about the calorie content in vape juice and whether nicotine can assist in weight loss. This article provides an in-depth look at these topics, examining the ingredients in vape juice, the presence of calories, and the role of nicotine in weight management.

Understanding Vaping

Vaping involves using an electronic device to inhale vapor created by heating a liquid known as e-liquid or vape juice. These devices are widely used for various reasons, including as an aid to quit smoking, for recreational purposes, or simply to enjoy the wide variety of available flavors.

Composition Of Vape Juice

Vape juice is made up of several components, each serving a specific function:

  • Propylene Glycol (PG): This is a synthetic compound that helps distribute flavor evenly throughout the liquid.
  • Vegetable Glycerin (VG): Derived from vegetable oils, VG is responsible for producing the thick vapor clouds that many vapers enjoy.
  • Flavorings: These are food-grade additives that provide the diverse range of flavors available in vape juices.
  • Nicotine: Optional and customizable, nicotine is included for those who want it, particularly ex-smokers seeking to manage cravings.

Do Vapes Contain Calories?

Yes, vape juices do contain calories, primarily from PG and VG. However, the calorie content is very low. Typically, one milliliter of vape juice contains approximately 4-5 calories. This is a tiny amount compared to the calories in food or beverages. Because the liquid is vaporized and not consumed in the traditional sense, these calories do not significantly affect the body.

Impact Of Vape Juice Calories On Weight

The minimal calories in vape juice are unlikely to contribute to weight gain. When vaping, the e-liquid is heated and turned into vapor, which is inhaled. This process does not involve ingesting the liquid, and thus, the caloric content is not absorbed by the body in a meaningful way. Therefore, vaping does not contribute to calorie intake in the same manner as eating or drinking.

Caloric Needs Of The Human Body

An average adult requires about 2000-2500 calories daily, depending on factors like age, sex, physical activity, and overall health. These calories are needed to maintain bodily functions and energy levels. Given the tiny caloric content of vape juice, it does not significantly affect weight or meet these daily requirements.

Calories In Vape Juice & Diets

For individuals following specific diets, such as the ketogenic (keto) diet, which focuses on low carbohydrate intake, the calories in vape juice are generally insignificant. Vape juice contains negligible carbohydrates and calories, so it does not interfere with the metabolic state of ketosis. While some flavorings may have minute traces of carbohydrates, these are usually too small to impact the diet adversely.

The Role Of Nicotine In Weight Loss

Nicotine has been known to have appetite-suppressing properties and can increase metabolic rate slightly, leading to a temporary boost in calorie burning. This is why some people may experience weight loss when they start using nicotine products, including vaping. However, using nicotine as a weight loss tool is not advisable due to its addictive nature and potential health risks, such as increased heart rate, hypertension, and the risk of developing cardiovascular diseases.

Health Considerations

While vaping is often perceived as less harmful than smoking traditional cigarettes, it is not without risks. The long-term health effects of inhaling vaporized substances are still under study, and concerns about respiratory issues, addiction, and potential exposure to harmful chemicals remain. Therefore, using vaping as a strategy for weight management is not recommended.


In summary, while vape juices do contain minimal calories, these are not absorbed by the body in a way that would impact weight. The main components of vape juice, PG and VG, contribute to these calories, but the amounts are too small to be significant. Additionally, nicotine can influence weight by suppressing appetite and slightly boosting metabolism. Still, it is not a safe or effective method for weight loss due to its addictive nature and associated health risks. For those concerned about their weight, a balanced diet and regular physical activity remain the most effective and healthy approaches.


Do vape juices have a lot of calories?

No, vape juices contain very few calories, typically around 4-5 calories per milliliter, which are not enough to significantly impact weight.

Can vaping affect my dietary plans?

Generally, no. Vape juice’s caloric content is negligible and does not interfere with diets like keto or low-carb plans.

Is nicotine effective for losing weight?

While nicotine can suppress appetite and slightly boost metabolism, it is not a recommended or safe method for weight loss due to its health risks.

Are the calories in vape juice absorbed by the body?

No, the calories in vape juice are not absorbed in the same way as those in food or drink, as the liquid is vaporized and inhaled rather than ingested.
