Vaping's effect on hunger is mixed: nicotine typically suppresses appetite and slightly boosts metabolism, which can reduce hunger for many, but sweet-flavored vapes or behavioral habits can trigger cravings for sugary snacks, making some people feel hungrier or snack more. So, while nicotine often curbs appetite, sweet flavors and psychological associations can lead to increased snacking and perceived hunger, making vaping's impact on appetite inconsistent.
Understanding the Connection Between Vaping and Appetite
Nicotine's Effect on Hunger Hormones: Nicotine can initially suppress appetite by activating the body's stress response, which diverts energy away from digestion. However, as nicotine wears off, blood sugar levels may drop, which can stimulate feelings of hunger.
The Science Behind Vaping and Hunger
Nicotine can stimulate the release of certain hormones, such as dopamine and norepinephrine, affecting hunger and satiety. Additionally, the flavourings and sweeteners used in e-liquids can activate the brain's reward centres, leading to cravings for sweet or fatty foods.

Nicotine can help suppress your appetite in a small way, but the data we have on vaping raises health concerns similar to smoking and with very little evidence that it actually helps with weight loss. So, some people might feel less hungry when they vape, leading to a minor decrease in calorie intake.
Signs a person is vaping
Yes, your e-juice does contain calories, but the short answer is, it's not very many. One study cited by Colombia University quotes roughly 20 calories per a typical vape cartridge [4], meaning vape juice is unlikely to bring on any unwanted weight gain on its own.
Facts on vaping harms
If you're worrying about your daily vape puff count, there's no official “normal”. Most people vape between 100-500 puffs a day, but it can vary widely based on: device. nicotine strength.
Vaping has been linked to greater risk of chronic lung diseases like asthma or chronic bronchitis, as well as heart problems including heart failure, and continuing to vape after an EVALI diagnosis may cause permanent scarring in your lungs. Vaping may also lower some measures of lung function over time.
The particles you inhale while vaping can cause inflammation (swelling) and irritation in your lungs. This can lead to lung damage like scarring and narrowing of the tubes that bring air in and out of your lungs.
The Caloric Impact of Vaping
This is because the vapour is inhaled into the lungs, not ingested like food or drink. This means that vaping will not effect your fasting or if you are on a diet, you do not need to calorie count vaping.
Calculating Vape Calories: A Simple Breakdown
So, for instance, if your vape device offers 600 puffs, like our Elf Bar vape pods, it might pack around 30 calories. And if your device holds 10 ml of e-liquid, you're looking at approximately 50 calories for the whole setup.
So, in a word, NO: e-liquids do not contain sugar. However, there are some ingredients present in the juice that might explain the sweet taste.
Those recurring infections aren't coincidental, warns Dr. Galiatsatos; they are red flags. Research has shown that pneumonia, bronchitis, and other lung infections are more common in people who vape. Though these effects might not immediately be life-threatening, doctors worry about the long-term consequences.
If you or someone else vapes indoors in the home or office, it can create a strong odor that doesn't just go away with an air freshener.
Stealth vaping means discreet vaping. When you stealth vape, you use your vape in a way that people will not notice unless they pay close attention. This involves using smaller, lower-powered devices which can be held in the palm of your hand, and vaping with high PG e-liquid.
What Is Considered Heavy Vaping? While there is no definite metric to determine heavy vaping, using more than 10 mL of e-liquid or refilling multiple times a day is typically considered heavy vaping. However, the vapers used can add nuance.
But vaping might actually be worse for your lungs.
Many people assumed this was a safer way to smoke. “Because of the chemical composition, vaping is similar to inhaling an acetylene welding torch,” explains Dr. Thau. “To make it more palatable, they add other chemicals.
There's no exact number, but roughly 10-15 vape puffs can equal one cigarette, though this varies greatly; it could be as few as 4 puffs with high-nicotine liquid or up to 50 puffs with weaker liquid, depending on puff duration, device power (pod vs. mod), and e-liquid strength (like 5% vs. 12mg/mL). A single cigarette delivers about 1-2 mg of nicotine, while a vape's nicotine delivery changes significantly with user style and device settings.
A 2024 study1 has confirmed that young people who vape perform worse in exercise tests. In fact, their exercise performance was on par with those who smoked! “They found it harder to breath, their muscles became more fatigued, and they were less fit overall.”
Many people who smoke find their eating habits change when they quit cigarettes/vaping. Some people experience increased hunger as a withdrawal symptom, but research suggests their eating patterns eventually will return to normal.
NEVER drink e-liquid, or allow anyone to drink it, because the liquid nicotine can be poisonous. If a person of any age drinks e-liquid, accidental or not, immediately call Poison Control at 1-800-222-1222.
Yes, lungs can begin to heal and show significant improvement after 7 years of vaping once you quit, with inflammation decreasing and lung function improving, but the extent of recovery depends on the damage; the sooner you stop, the better the chance for healing, though extensive, long-term damage might be permanent, emphasizing the need to quit for the best possible outcome and consulting a doctor for persistent issues.
