Quick answer

A 12:12 fasting schedule means fasting for 12 hours and eating within a 12-hour window.

Step by step

01 Choose a realistic eating window for the 12 hours.
02 Set a fasting start time and end time before the day begins.
03 Track at least 3 attempts before deciding if 12:12 works for you.

The longer answer

For for workdays, the useful part of 12:12 is not perfection; it is having a repeatable start and end time. For example, if you finish eating at 8:00 PM, a 12-hour fast ends at 8:00 AM the next day. Adjust the window around sleep, work, hunger, and social life.

Tip

Choose an eating window that does not fight your work schedule.

Common mistake

Choosing 12:12 only because it sounds popular, not because it fits your day.

Safety note
Longer fasting windows are not automatically better. If you feel dizzy, faint, unusually anxious, or unwell, stop and get qualified medical advice. People with medical conditions or medications should ask a clinician before fasting.
