Can I fast if I drink coffee every morning?

Quick answer

Yes, if the coffee is black and you tolerate caffeine well; milk, sugar, and cream change the answer.

Step by step

01 Keep coffee black.
02 Do not suddenly double caffeine.
03 Track jitters, sleep, and hunger.

The longer answer

Coffee can help some people with fasting, but too much caffeine on an empty stomach can worsen anxiety, nausea, or headaches.

Tip

Coffee should help the fast, not run the whole app.

Common mistake

Replacing food with too much caffeine.

Track in the app
