What Custom means
Custom intermittent fasting lets you define your own fasting and eating lengths when 16/8 or other presets do not fit shift work, travel, or training. Limotein still keeps the timer first.
Who it fits
- Shift workers and irregular schedules
- Travel days and late events
- People bridging between standard windows
Example day
- Choose fasting hours that you can repeat this week
- Align the eating window with meals you can actually take
- Adjust tomorrow instead of forcing a broken preset
How to run it in Limotein
- Open Custom window in Limotein
- Set fasting and eating lengths that match your day
- Start when the fast begins and keep the timer visible
- Log meals only inside your chosen eating window if you track
Practical tips
- Consistency beats a heroic one-off custom day
- Write down why you customized, so the next day is intentional
- Medical conditions still come first. Fasting is optional
Limotein is a tracking tool, not medical care. Read the Disclaimer before changing how you eat or fast.
FAQ
What is a custom intermittent fasting window?
A custom window means you set your own fasting and eating durations instead of using presets like 16/8 or 18/6.
When should I use custom fasting?
When work, travel, or training makes standard ratios impractical, but you still want a clear start and end for the fast.
Does Limotein support custom fasting?
Yes. Build a custom window, start from Today, and keep elapsed time on screen or on a home widget while you fast.
