Can I drink lemon water during intermittent fasting?

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

A small amount of lemon water is usually fine for a practical fast, but strict fasting keeps water plain.

Step by step

01 Use a small squeeze only.
02 Avoid sugar or honey.
03 Track if it helps hydration without triggering hunger.

The longer answer

Lemon adds flavor and tiny calories. For most people, the bigger issue is whether it triggers cravings or becomes a sweetened drink.

Tip

Lemon water is not magic; it is mostly a hydration tool.

Common mistake

Adding honey and still calling it lemon water fasting.
