16:8 / 18:6 / Custom plan16 hours fasting, 8-hour eating window. The most common plan for beginners.
Intermittent fasting is an eating pattern where you eat during set hours and close your eating window the rest of the time. The focus is less on what you eat and more on when you eat. Dayfast helps you follow that rhythm with timers, plans, and reminders.
