The Importance of Staying Hydrated During a Fast
During any fasting period, whether for intermittent fasting or a more extended fast, maintaining proper hydration is paramount. Dehydration can lead to fatigue, headaches, dizziness, and intense hunger pangs that make fasting difficult to sustain. The right fluids will help you manage these symptoms and support your body's natural processes, such as flushing out waste and regulating temperature.
Acceptable Fasting Drinks
Water: The Cornerstone of Hydration
Plain water is your most reliable ally during a fast. It contains zero calories, ensuring it won't break your fast, and is essential for all bodily functions. You should aim for at least two to three liters of fluid per day, focusing on mineral-rich water to help replace lost electrolytes.
Plain Coffee: A Calorie-Free Energy Boost
Black coffee is a popular choice for many fasters. It contains almost no calories and can provide a welcome caffeine boost for energy and mental alertness. The caffeine can also act as an appetite suppressant, helping to curb hunger. Crucially, it must be consumed black, without any sugar, milk, or creamers, as these additives can trigger an insulin response and break your fast.
Unsweetened Teas: Soothing and Antioxidant-Rich
Like black coffee, unsweetened tea is another excellent zero-calorie option. Green and black teas are especially beneficial due to their antioxidant properties. Herbal teas, such as peppermint, chamomile, or hibiscus, are also permissible, as long as they contain no added sweeteners. They can provide warmth and flavor variety to help get you through a fast.
Apple Cider Vinegar: A Digestive Aid
A small amount of diluted apple cider vinegar (1-2 teaspoons mixed in water) is considered acceptable by many fasters. It is believed to support digestive health and may help stabilize blood sugar and control appetite. The taste can be strong, so diluting it is key.
Bone Broth: For Longer Fasts and Electrolytes
For more extended fasting periods, bone broth can be a beneficial addition, though it does contain some calories. It is rich in electrolytes and nutrients that can be depleted during a prolonged fast, making it a good option for replenishing minerals. However, it is important to note that consuming bone broth will technically break a strict fast aimed at autophagy, so personal goals should be considered.
Drinks to Avoid While Fasting
To maintain the fasted state, it is critical to avoid any drinks containing sugar, artificial sweeteners, or significant calories.
- Sugary drinks: This includes sodas, fruit juices, and sweetened iced teas. The sugar will spike your insulin and end your fast instantly.
- Diet drinks: While calorie-free, many artificial sweeteners can still trigger an insulin response or increase cravings, undermining your fast.
- Milks and creamers: Even a small amount of milk or cream in your coffee adds calories and fat, which will break your fast. This includes non-dairy milks like almond or oat milk.
- Alcohol: Alcohol contains calories and also impairs judgment, which could lead to breaking your fast with food.

Tips for Choosing Your Fasting Beverages
- Prioritize Water: Always make plain or mineral water your go-to. It is the most important liquid for staying healthy during a fast.
- Listen to Your Body: If coffee on an empty stomach gives you jitters, opt for a calming herbal tea instead. Everyone's reaction to caffeine and other drinks differs.
- Understand Your Goals: If your goal is deep cellular repair (autophagy), you may need to be stricter and stick to only water. For simple weight management through intermittent fasting, a splash of lemon in water is likely fine.
- Experiment with Flavors: To combat boredom, try adding a small slice of lemon or cucumber to your water for a subtle flavor change without added calories.
- Don't Overdo It: While black coffee can help, excessive amounts of caffeine can lead to negative side effects like anxiety and a rapid heart rate.
Conclusion
Navigating what to drink while fasting is straightforward once you understand the basic principles of consuming zero or very low-calorie beverages that do not trigger an insulin response. Water remains the undisputed champion, providing essential hydration and helping to manage hunger. Black coffee and unsweetened teas offer additional variety and benefits, including appetite suppression and antioxidants. By focusing on these core options and avoiding high-calorie or sweetened drinks, you can successfully support your body through your fasting period. It is always wise to consult with a healthcare professional, especially for longer fasts, to ensure your approach aligns with your health needs and goals.
