Electronic cigarettes, commonly known as vapes, have become increasingly popular, especially among adolescents and young adults. While often marketed as a safer alternative to traditional cigarettes, concerns remain about their potential health risks and their effectiveness as a smoking cessation tool. One area of growing interest is the relationship between vaping and weight control, a connection previously established with traditional cigarette smoking. This article delves into the existing research to explore the intricate link between e-cigarette use and body weight changes, particularly among young people.
What are E-cigarettes?
Electronic cigarettes are battery-operated devices that heat a liquid, often containing nicotine, flavorings, and other chemicals, to create an aerosol that users inhale. These devices come in various forms, including vape pens, e-hookahs, mods, and tank systems. The rising popularity of e-cigarettes, especially among teenagers, can be attributed to factors such as appealing flavors, perceptions of reduced harm compared to traditional cigarettes, and, notably, weight management considerations.
The Misconception of Vaping as a Weight Loss Strategy
Adolescents are particularly vulnerable to body image pressures and weight management concerns, fueled by media portrayals of idealized body types and the constant comparisons facilitated by social media. This pressure can lead some young people to turn to vaping as a misguided means of weight control, based on misconceptions about its appetite-suppressing effects and its potential as a substitute for snacking.
Research into Vaping and Weight Control
Several studies have explored the relationship between e-cigarette use and weight control, particularly among adolescents and young adults.
Studies on Weight Concerns and Vaping
Research suggests a correlation between e-cigarette usage and increased weight concerns, especially among females. Some studies indicate that regular e-cigarette users who are overweight and actively restrict calories are more likely to view vaping as a weight loss or control strategy.

One study involving 2327 participants found that lower body esteem in women was associated with a higher likelihood of e-cigarette use a year later, mediated by weight control expectations. This highlights the potential for negative body image to drive vaping behavior among young women.
Conflicting Findings
However, the research on this topic is not always consistent. While some studies suggest that vaping may help with weight management or prevent weight gain after quitting smoking, others show mixed or uncertain results.
For example, one study did not identify any direct correlations between using e-cigarettes specifically for weight control purposes. Instead, it observed that teenagers who engaged in poor weight control practices were more likely to become e-cigarette users.
Flavor Preferences and Appetite Suppression
Some research suggests that the use of flavor-infused e-liquids may be linked to appetite control and weight reduction. One study found that approximately 13.8% of high school teenagers use flavor-infused e-liquids to suppress appetite, with 9.3% using them for weight loss. The consumption of these e-liquids was associated with higher vaping frequency and increased intake of flavored e-liquids.
Gender Differences
Several studies have noted gender differences in the relationship between vaping and weight concerns. For example, one study found that overweight and obese female smokers experimented with e-cigarettes more frequently than their male counterparts. Another study identified a robust correlation between e-cigarette usage among female teenagers and their perceived weight status, with those who perceived themselves as overweight being more likely to report having used e-cigarettes.

Cardiovascular Risks
It's crucial to acknowledge the cardiovascular risks associated with both traditional cigarettes and e-cigarettes. Inhaling aerosolized nicotine salt containing liquids from e-cigarettes may elevate the risk of cardiovascular diseases by inducing sympathetic dominance and cardiac arrhythmias. This challenges the notion that e-cigarettes are entirely risk-free for cardiovascular health.
Nicotine and Weight Management
Research suggests that nicotine can help manage weight by reducing appetite and food intake, possibly by affecting the release or activity of neuropeptide Y (NPY) and pro-opiomelanocortin (POMC), proteins involved in regulating hunger and satiety.
However, while nicotine may have short-term effects on weight management, there is no evidence that short-term nicotine use prevents weight gain in the long term. Continued use of a nicotine product may be necessary to maintain any potential weight-related benefits.
Non-Nicotine Vaping and Weight Management
Not all vapes contain nicotine. Some include nicotine-free fluid, cannabis, or CBD. While cannabis is known for its appetite-increasing properties, research on how cannabis vaping specifically affects weight is limited.
Regarding CBD, some studies suggest that it may lead to a reduction in appetite or body weight, while others find no significant changes or even increased appetite.

It's also possible that weight-management mechanisms associated with vaping may extend beyond nicotine's effects, encompassing factors like taste perception, physical mouthfeel, and behavioral substitution. These factors could potentially apply to any vape, regardless of its nicotine content.
Vaping and Smoking Cessation
Fear of weight gain is a significant barrier to smoking cessation. E-cigarettes may help some individuals quit smoking by providing continued exposure to the appetite-suppressant effects of nicotine and the behavioral aspects of vaping.
However, it's important to note that there is no strong evidence supporting the hypothesis that vaping prevents weight gain after smoking cessation.
Healthy Alternatives for Weight Management
Given the potential health risks associated with vaping, it is essential to explore healthier alternatives for weight management:
- Balanced diet and nutrition: Focus on eating a balanced diet rich in fruits, vegetables, healthy fats, and whole grains. Manage portion sizes and incorporate nutrient-dense foods.
- Regular physical activity: Engage in regular exercise or physical activities, including cardio workouts, strength training, yoga, or simply staying active throughout the day.
- Support groups or counseling: Join support groups focused on weight management or seek counseling for guidance and motivation.
- Fitness apps: Utilize fitness apps to track food intake and exercise.
- Mindfulness and stress management: Practice techniques like meditation, yoga, or deep-breathing exercises to manage stress and emotional eating.
- Aim for gradual weight loss: Losing 1-2 pounds each week is a safe and sustainable approach.
- Set short-term goals: Break down a weight loss goal into achievable steps per week or month.
- Focus on other benefits: Recognize that increasing physical activity and healthy eating have benefits beyond weight loss, such as improved mood, increased energy, and new skill development.
- Track progress: Use an app or device to monitor progress.
- Get enough sleep: Prioritize good quality sleep to help reduce weight gain and support healthier eating habits.
Vaping: Not an Effective Long-Term Weight Loss Method
While some studies suggest that nicotine in vaping might suppress appetite and affect weight, the evidence is still limited and doesn’t support vaping as a reliable weight loss method. Factors like nicotine's effect on appetite and behavioral aspects might play a role, but clear evidence supporting vaping as a reliable weight management tool is lacking.
Vapes containing nicotine may help prevent weight gain and lead to weight loss in the short term. However, vaping is not an effective long-term weight loss method and may have health risks.
