If you’re fasting and wondering what you can drink without breaking your fast, you’re not alone. Whether you’re doing a 16:8 intermittent fast or a longer 24-hour fast, the drinks you choose can support or sabotage your results.
In this post, you’ll learn exactly what you can drink while fasting — and why. Plus, I’ll share my personal go-to drinks for energy, focus, and hydration during a fast.
Why It Matters What You Drink During a Fast
Fasting triggers important metabolic changes — like autophagy, insulin sensitivity, and fat burning. Some drinks can support these processes, while others may interrupt them by spiking insulin or adding hidden calories.
Understanding what drinks are truly fasting-safe can help you feel better and fast longer without breaking the benefits.
🥤 Safe Drinks That Won’t Break Your Fast
If you’re wondering what you can drink while fasting, you’re not alone. Whether you’re doing a 16:8 intermittent fast or a longer 24- to 48-hour fast, choosing the right drinks can make or break your experience.
Below are the best fasting-safe beverages — backed by science and real-life experience.
✅ 1. Water (Still or Sparkling)
Plain water is essential while fasting. It hydrates your cells and supports detoxification. Sparkling water is okay too — just skip the sweetened or flavored versions.
✅ 2. Black Coffee
Unsweetened black coffee contains zero calories and may even boost fat burning and mental clarity. Just avoid creamers and sweeteners.
✅ 3. Herbal Tea (No Additives)
Peppermint, green tea, ginger, or rooibos are all great options — as long as they’re unsweetened and calorie-free.
✅ 4. Apple Cider Vinegar (Diluted)
A tablespoon diluted in water may help with digestion and appetite control. Just don’t drink it on an empty stomach if you’re sensitive.
✅ 5. Electrolytes (Clean + Unsweetened)
Fasting depletes sodium, magnesium, and potassium. Choose unsweetened, zero-calorie electrolytes to prevent headaches, fatigue, and cramps.

What to Avoid While Fasting
Even small calories or insulin spikes can interfere with your fast. Avoid:
- Juice or fruit-infused drinks
- “Zero-calorie” sodas (can trigger insulin with sweeteners)
- Creamer, milk, oat milk
- Protein shakes or BCAAs
💡 Pro Tip – Go Green
Matcha or green tea contains catechins and a gentle dose of caffeine. It’s great for metabolism, clarity, and appetite suppression — just don’t add honey or milk.

🧂 What to Add for Better Results
If you’re feeling sluggish while fasting, it might be low electrolytes. A clean blend like Nutri-Align or LMNT can:
- Reduce fatigue and muscle cramps
- Help with headaches
- Keep your fast sustainable — especially if you’re active
🧠 Frequently Asked Questions (FAQ)
Q: Can I drink lemon water while fasting?
A squeeze of lemon may be okay during short fasts, but it may trigger digestive enzymes in longer fasts. Best to avoid if you’re aiming for strict autophagy.
Q: Does coffee with MCT oil break a fast?
Technically yes — it contains calories. But for fat fasting or performance fasting, it’s commonly used to extend satiety.
✅ Final Thoughts: Drink Smart, Fast Strong
Knowing what you can drink while fasting helps you stay energized, avoid fatigue, and maximize the benefits of your fast.
Stick with clean, simple options and consider adding electrolytes for better results — especially on fasts longer than 16 hours.
