Does green tea break a fast?
Quick answer
Plain green tea usually does not break a fast.
Step by step
01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether green tea contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move green tea to your eating window.
The longer answer
Plain green tea usually does not break a fast. The key is keeping it unsweetened and milk-free. For most intermittent fasting routines, the safest fasting-window drinks are water, plain tea, and black coffee. If your fast is for a medical test or religious purpose, follow those specific rules instead.
Tip
Use Fast Goblin notes to mark gray-area choices like green tea, then compare hunger and consistency over a few fasts.
Common mistake
Assuming green tea is automatically fasting-safe without checking the label or your fasting goal.
Track in the app
