Does Vaping Break a Fast? The Impact of Vaping on Intermittent, Water, Juice & Religious Fasting

An Overview of Fasting

Fasting is the practice of voluntarily abstaining from some or all food and drink for a set period of time. Many major religions incorporate periods of fasting into their rituals and rites. It is often undertaken as a spiritual practice to grow closer to God, purify the body and mind, or cultivate gratitude. More recently, various forms of fasting have gained popularity for potential health and weight loss benefits.

Common types of fasting include:

• Intermittent fasting - Alternating between periods of fasting and eating within a 24 hour timeframe
• Water fasting - Consuming only water for a stretch of time, often 24-72 hours
• Juice fasting - Restricting intake to fruit and vegetable juices
• Religious fasts - Abstaining from all or certain foods for spiritual reasons, often for 1-2 days

Guidelines on what is allowed or prohibited during a fast vary across fasting methods. This determines whether behaviors like vaping are considered compliant with the fast or not.

The Role of Vaping

Vaping involves inhaling vapor produced from e-liquids heated in an electronic cigarette or vape pen. The e-liquids usually contain nicotine, flavors, vegetable glycerin, and propylene glycol. Vaping can deliver a concentrated dose of nicotine without the tar and carcinogens found in traditional cigarette smoke.

People may vape for reasons including:

• Smoking cessation - To quit or reduce cigarette smoking
• Enjoyment and taste
• Stress relief and relaxation
• Socialization with other vapers
• Nicotine addiction

The impacts of vaping on fasting depend on the vaper's intent and the type of fast being undertaken.

Does Vaping Break an Intermittent Fast?

Opinions vary on whether vaping affects the biohacking benefits of intermittent fasting. Critics argue vaping may:

• Stimulate insulin production, which intermittent fasting aims to avoid
• Activate reward centers in the brain, sabotaging the mental clarity sought
• Spike addiction cravings, making fasting more challenging

However, evidence suggests vaping during intermittent fasts has negligible metabolic or caloric effects. Most vaping liquids contain no calories or nutrients. Ingesting trace amounts of vegetable glycerin likely does not influence insulin levels enough to disrupt the fasted state.

For metabolic purposes, vaping appears compliant with intermittent fasting. But mental aspects of cravings and addiction may be considerations.

Tips for Vaping During Intermittent Fasts

• Use zero nicotine vape juice to avoid spiking cravings
• Vape minimally and track usage to avoid developing a habit
• Monitor if vaping triggers increased hunger or cravings
• Use fasting periods to cut back on vaping and nicotine dependence

Does Vaping Break a Water Fast?

Water fasting allows only plain water for a prescribed period, usually 24-72 hours. Consuming zero calories is the goal. Most vape liquids contain some calories from vegetable glycerin and flavorings, likely around 5-10 calories per ml.

While minimal, these calories technically break the rules of a pure water fast. However, the metabolic influence is negligible. Vaping a small amount of flavorless, zero nicotine juice once or twice may align reasonably with the spirit of a water fast for some fasters.

However, those very strict on water fasting definitions would likely avoid vaping entirely during the fasting window.

Tips for Water Fasting and Vaping

• Read labels carefully and use zero calorie vape juice
• Vape sparingly, if at all
• Consider vaping habits and if vape flavor/nicotine will trigger hunger
• Use fasts as opportunities to control vaping habits

Does Vaping Break a Juice Fast?

Juice fasts allow unsweetened 100% fruit and vegetable juices. Since vaping liquids contain no produce, vaping is not a technically acceptable part of a juice fast.

However, similarly to water fasting, the calories from glycerin in vape juice are minimal. Vaping pure vegetable glycerin without nicotine or flavors could align reasonably with the spirit of a juice fast for some people.

But strict adherents would abstain from all vaping during a juice fast, as no actual fruit or vegetable juices are consumed by vaping.

Tips for Juice Fasting and Vaping

• Read vape juice ingredients carefully
• Avoid nicotine as it may trigger hunger
• Vape minimally if at all during the fast
• Be mindful of vaping's influence on cravings

Does Vaping Break a Religious Fast?

Religious fasting rituals have specific prohibited foods and behaviors dictated by scriptures and traditions. These vary across faiths.

For example:

• Islamic fasts during Ramadan prohibit all food and drink during daylight hours.
• Hindu fasts often exclude grains, lentils, spices and oils.
• Jewish fasts on Yom Kippur and Tisha Bav forbid any food or drink.
• Catholic fasts exclude meat and limit meals to one full meal per day.

Vaping is unlikely to be permitted during religious fasts. Consuming any oral intake is typically prohibited. Check specific religious guidance to be certain.

Tips for Religious Fasting and Vaping

• Consult religious leaders if unsure of vaping's status
• Use fasting periods to control nicotine dependence
• Find alternate ways to manage stress and cravings
• Stay occupied with spiritual activities like prayer

Health Considerations When Fasting and Vaping

If you choose to vape during fasts, keep these health factors in mind:

• Nicotine absorption. Nicotine enters the bloodstream faster when vaping while fasted due to low insulin and stomach acid.
• Dehydration. Fasting can cause dehydration, exacerbated by vaping's drying effects.
• Heartburn and gut issues. PG/VG in vape juice can cause GI problems, already a fasting concern.
• Caffeine overdose. Vaping caffeine e-liquids can spike caffeine levels in the fasted state.

Stay well-hydrated, use nicotine-free juice, vape mildly, and monitor physical reactions closely. Consult a doctor before fasting if you have any medical conditions.

Is Vaping Permitted During Other Kinds of Fasts?

Beyond the major fasting categories covered already, some people practice custom fasts with personal guidelines. Examples include:

• Eliminating specific ingredients like sugar, carbs, or dairy
• Restricting eating to certain hours every day, like 16:8 intermittent fasting
• Consuming only specific foods or meal replacements
• Cutting calories drastically but not fully abstaining from food

These flexible fasts are often based on nutrient consumption and personal health goals. The impact of vaping depends on your custom fasts particular restrictions. Assess if vaping aligns with your stated goals or could potentially counteract the benefits.

The less restrictive the fast, the more leeway there may be for vaping. But discipline is still key.

Should You Fast and Vape?

Here are some final considerations around combining fasting and vaping:

• The strictest fasts prohibit all oral intake, including vaping.
• Nicotine and vape flavors may trigger hunger and cravings.
• Vaping has minimal metabolic impact, but may disrupt mental clarity.
• Use fasts as opportunities to control vaping habits and nicotine dependence.
• Stay hydrated, vape minimally, use zero nicotine juice.
• Consult a doctor before fasting if you have medical conditions.

An informed, moderate approach allows vaping periodically during less restrictive fasts. But you must closely monitor health, hunger levels and mental discipline. Work with trusted providers to determine risks and benefits for your situation.
