Intermittent Fasting

Intermittent Fasting is optional routine support for users who choose to follow a fasting window. It is guidance, not enforcement, medical advice, or a guaranteed fat-loss method.

Before you start #

• You must be signed in.
• Intermittent Fasting is live for all signed-in users on web, iOS, and Android.
• On mobile, update NutriTracker from the App Store or Google Play if the Settings entry or Fasting screen is missing.
• Do not use fasting without professional guidance if you are pregnant, have a history of eating disorders, have diabetes, take medication affected by meal timing, or have a medical condition.

Where to find it #

iOS #

1. Tap Settings.
2. Tap Coach.
3. Tap Intermittent Fasting.
4. For the timer, use the Fasting screen. An active iOS Live Activity can also open NutriTracker through nutritracker://fasting.

Android #

1. Tap Settings.
2. In the Coach section, tap Intermittent Fasting.
3. You can also use Settings search and search for Intermittent Fasting.

Web #

1. Open Settings.
2. Open Plans.
3. Click Open Fasting, or go directly to /fasting.

How to use it #

1. For coach-led setup, open Chat and ask your coach to help set up intermittent fasting. The coach asks one question at a time and should propose a realistic routine.
2. Review the proposal card and safety note. A plan is not created until you confirm it.
3. On web, you can also click Set up manually from /fasting, choose 12:12, 14:10, 16:8, 18:6, or Custom, set your eating window start and end, choose a goal, tick the safety acknowledgement, then click Create fasting plan.
4. On iOS and Android native v1, setup is coach-led. Manual setup remains available on web.
5. Use the Fasting dashboard to see the current phase, countdown, eating and fasting windows, today's focus, tasks, tips, and progress.
6. Use Start fast now or End fast now only when today's timing has genuinely changed.
7. Use Mark today as adjusted when life changed and you do not want the day treated as a normal fasting day.
8. Use Adjust with your coach to change the plan, or Pause fasting plan to stop it.

What happens next #

• The dashboard shows whether you are in an eating or fasting phase and when the next transition is expected.
• Food logging stays available at any time. The app does not block food or mark a changed window as failure.
• Meal reminder paths suppress meal nudges during active fasting windows.
• Daily Briefing may include fasting-aware context when an active plan exists.
• On iOS, the Live Activity starts after the app receives active fasting state and updates from app/API refreshes. Remote ActivityKit push updates are not currently part of v1.

Troubleshooting #

• I cannot see Intermittent Fasting. On web, try /fasting. On mobile, update the app, reopen NutriTracker, and check Settings > About NutriTracker. If the row is still missing, email help@nutritracker.io; Intermittent Fasting should be available to all signed-in users on current app versions.
• The fasting timer looks wrong. Refresh the app, check your device time and timezone, then open /fasting or the mobile Fasting screen. Use Adjust with your coach if the planned window is wrong.
• The banner says I am fasting but I have eaten. Use End fast now or Mark today as adjusted. NutriTracker treats adjustments neutrally.
• The iOS Live Activity is missing. Confirm you are on an iOS build with fasting support, have an active plan, and have opened the app after the plan became active. Also check iOS Live Activities settings for NutriTracker.
• I want to stop fasting. Open the Fasting screen and use Pause fasting plan, or ask your coach to stop the plan and use non-fasting routine support.

Privacy and safety notes #

• Fasting is not suitable for everyone. NutriTracker does not provide medical fasting advice.
• Fasting state can affect reminders and coach context while a plan is active.
