Vaping and Calories: What You Need to Know


Making informed choices about what you put into your body is essential for maintaining a healthy lifestyle. If you’re considering switching from smoking to vaping, you’re likely concerned about the impact on your overall well-being, including your weight. In this comprehensive article, we’ll address the question: Do vapes have calories? We’ll also explore how vaping might affect your weight, discussing the caloric content of vaping components and their impact on your diet.

Do Vapes Have Calories?

As you explore the transition from smoking to vaping, you may have heard contrasting beliefs about vaping’s effects on weight. Some suggest that vaping can aid in weight loss, while others argue otherwise. The truth is, there is no substantial evidence to support vaping as a weight loss tool.

However, it’s equally important to clarify that vaping is unlikely to make you gain weight either. While vaping components do have caloric content, your body cannot absorb these calories unless they enter your digestive system. Your lungs do not play a role in weight gain. Moreover, the caloric content of vape juice is so negligible that it’s almost inconsequential.

To understand whether vaping has calories, let’s start by examining the components of vape juice:

How Many Calories Are in a Vape?

To determine how many calories are in a vape, it’s crucial to understand the caloric content of the individual components of vape juice. A typical vape juice includes:

  • A Carrier Blend: This blend usually consists of vegetable glycerin (VG) and propylene glycol (PG) in a 50/50 ratio. The carrier blend makes up the majority of the e-liquid, typically over 90%.
  • Flavors: Vape juice contains food-grade flavors, which are highly concentrated. These flavors are typically mixed with VG or PG, making up a small portion of the e-liquid, usually around 10%.
  • Nicotine: Nicotine content varies but is a tiny percentage of the overall mixture.

Considering these components, we can calculate the caloric content of a vape. VG contains approximately 4.32 calories per gram, while PG contains about 4 calories per gram. The weight of VG is slightly higher than PG, making it a bit more calorically dense.

For instance, if you filled a 2 ml vape tank with e-liquid consisting solely of VG, the entire contents of the tank would contain roughly 10.89 calories. This represents the maximum caloric content a vape can have, unless you have a larger tank.

How Many Calories Are in Vape Juice Flavors?

Flavorings used in vape juice are highly concentrated, and they make up only a small portion of the mixture. Typically, VG and PG are the carriers for these flavors. While alcohol-based flavors are occasionally used in vape juice, alcohol contains 7 calories per gram. However, the amount used in vape juice is so minimal that its impact on the e-liquid’s calorie count is nearly immeasurable.

How Many Calories Are in Nicotine?

Nicotine itself does not contain a measurable number of calories.

Based on what we’ve learned, it can be concluded that a vape or a bottle of e-liquid contains approximately 5 calories per ml. However, this caloric intake is minimal compared to other dietary sources. Even if you were to vape 2 ml of juice daily, you’d inhale just around 10 calories, which is negligible in the context of your overall diet.

Does Your Body Absorb Calories from Vaping?

Your body absorbs calories when food travels through your digestive system. Vaping, on the other hand, does not involve digestion in this manner. The minute amount of vapor that might condense in your mouth and be swallowed is so insignificant that measuring its caloric impact is virtually impossible. Therefore, vaping does not contribute to calorie absorption.

Can Vaping Make You Gain Weight?

Vaping cannot lead to weight gain through calorie consumption. The caloric content of vape juice is minimal, and your body does not absorb calories through your lungs. Vaping, in itself, will not make you gain weight.

Can Vaping Make You Lose Weight?

Vaping is not a direct method for weight loss. Weight loss primarily depends on creating a calorie deficit by either monitoring your food intake or increasing physical activity. Vaping does not inherently contribute to either of these aspects.

However, if you find that vaping satisfies your sweet cravings and helps you consume fewer snacks or sugary beverages, it could indirectly support weight loss by changing your dietary habits. Nevertheless, it’s essential to remember that vaping should not replace a comprehensive weight management plan. Successful weight loss involves a holistic approach that includes dietary choices, exercise, and lifestyle adjustments.


In conclusion, the caloric content of vapes is minimal and not a significant factor in your diet. Vaping does not impact your caloric intake because your body cannot absorb calories through inhalation. While vaping may indirectly contribute to weight loss by curbing sweet cravings, it should not be relied upon as a sole method for losing weight. If you’re aiming for weight management, focus on a balanced diet, regular exercise, and overall well-being. Vaping can be part of your lifestyle choices, but it should not be seen as a weight loss solution.
