A 2020 study found black coffee did not affect glucose levels after a 10-hour fast. This is great news for coffee lovers asking: can I have espresso while intermittent fasting? Yes, you can, but with a few important rules.

A standard shot of black espresso contains fewer than 5 calories, and for many people, the question arises: can I drink espresso coffee while fasting? This minimal caloric content means plain espresso generally does not disrupt a fast, but the answer depends on your specific fasting goals.
