Intermittent Fasting Window Designer
Design an intermittent fasting schedule tailored to your preferred first meal time. Enter daily fasting hours, when you want to break your fast, and the number of meals you plan to eat to see the eating window, meal spacing, and hydration reminder cadence.
Wellness planning aid only; confirm any fasting protocol with a healthcare professional.
Examples
- 16 h fast, first meal 12.5, 2 meals, 2 h reminders ⇒ Feeding window: 12:30 PM–8:30 PM (8.00 h) | Meal spacing: every 4.00 h | Hydration reminder every 2.00 h
- 18 h fast, first meal 10.75, 3 meals, blank reminders ⇒ Feeding window: 10:45 AM–4:45 PM (6.00 h) | Meal spacing: every 2.00 h | Hydration reminder every 2.00 h
FAQ
What if I start fasting after midnight?
Enter the first meal time in 24-hour decimal format; the designer rolls the schedule across midnight automatically.
Can I plan snacks in addition to meals?
Increase the meal count to reflect any snacks so the spacing output accounts for those extra feedings.
How precise are the hydration reminders?
The reminder interval rounds to two decimals, so a value like 1.5 will trigger prompts roughly every 1 hour and 30 minutes.
Additional Information
- Time inputs use decimals, so 18.5 represents 6:30 PM; the tool converts them to a 12-hour clock output.
- Meal spacing divides the available eating window by the rounded number of meals to keep intervals even.
- Hydration reminders default to every 2 hours to encourage steady water intake during the feeding window.
