A 13:11 fasting schedule means fasting for 13 hours and eating during a 11-hour window. For weekends and social plans, one simple version is to start fasting at 9:00 PM and break the fast at 10:00 AM the next day.
Set your goal to 13 hours, tap start, and watch the ring fill. Streaks, history, and home-screen widgets keep you on rhythm — all private on your iPhone.
Yes — black coffee, plain tea, and water won't break a 13:11 fast. Skip milk, sugar, and sweeteners.
No problem. End the fast, log it, and start fresh tomorrow. Consistency over weeks matters more than any single day.
Use this page as a practical 13:11 schedule starter. It is built for people who want flexibility around friends, family meals, and travel, with a sample clock window and simple tracking advice.
| Window | Time | What it means |
|---|---|---|
| Start fasting | 9:00 PM | Finish your last meal and start the timer. |
| Break fast | 10:00 AM | Your 13-hour fast is complete. |
| Eating window closes | 9:00 PM | Finish meals before the next fast starts. |
Use the schedule as a guide, not a punishment. A weekend version should make it easier to return to the routine, not make you feel like you failed.
