Lemon water: does it break a fast?

Does not break a fast

A squeeze of lemon is about 2–5 kcal: in practice it does not break a fast. Claims that it "detoxes" or speeds up your metabolism are not supported. If you drink it often, rinse your mouth with water afterwards to protect your teeth.

Approximate energy: ≈2–5 kcal
