Can You Drink Coffee While Fasting?

Yes, plain black coffee is generally fine during intermittent fasting because it contains very few calories. Johns Hopkins Medicine lists black coffee and tea among zero-calorie beverages that can be consumed during fasting.

Keep it plain. Adding milk, cream, sugar, or flavored syrups adds calories and can interfere with a strict fast.

Black coffee may also help you feel more alert during a fasting period. However, caffeine can cause stomach discomfort or worsen heartburn for some people, especially when consumed on an empty stomach.

If coffee bothers your stomach, consider drinking less or having it later in your eating window. For most people following intermittent fasting, plain black coffee can fit comfortably into the fasting period.
