Can I drink tea while fasting?

Last reviewed · Jun 29, 2026 · Not medical advice
Quick answer

Yes, plain unsweetened tea usually fits an intermittent fasting window.

Step by step

01 Choose plain tea.
02 Skip milk and sugar during the fast.
03 Log it if caffeine affects your sleep or hunger.

The longer answer

Tea is commonly treated like black coffee: fine if it is unsweetened and has no milk. Sweet tea, chai with milk, boba tea, or tea lattes should be counted as eating-window drinks.

Tip

Green, black, and herbal teas can all work if unsweetened.

Common mistake

Forgetting that cafe tea drinks often contain sugar.
