How to use the intermittent fasting timer

D
Written by Daniil Zinenko

What is fasting in Welmi?

Intermittent fasting in Welmi means a scheduled break between meals — for example, an overnight pause between dinner and the next day's first meal. It is not extreme restriction or starvation. The fasting block on the Nutrition tab tracks your eating window and fasting periods.

Setting up your plan

  1. Find the intermittent fasting block on the Nutrition tab.

  2. Tap the > button to the right of the block header.

  3. Open the plan settings.

  4. Select a plan (16:8, 14:10, etc.).

  5. Confirm your selection.

The timer begins tracking immediately.

Changing your schedule

Switching plans: open the block settings (>) → choose a different plan → confirm.

Manual adjustment: open the block settings (>) → Manual schedule → adjust start/end times → confirm.

Note: Changing your schedule mid-session may recalculate your accumulated time.

Ramadan / religious fasting

Use Manual schedule and set the fasting end time to match iftar or your designated meal break.

Disabling fasting tracking

You can turn off the intermittent fasting block in your profile settings:

  1. Open your Profile.

  2. Go to Nutrition screen sections.

  3. Turn off Fasting.

The intermittent fasting block will be removed from the Nutrition screen.

Disabling fasting notifications (iPhone)

Go to Settings → Notifications → Welmi and disable notifications.

FAQ

Question

Answer

How do I change my fasting window?

Open the block settings (>) to pick a preset or Manual schedule to set custom times.

Can I edit past fasting days?

Not currently possible.

The timer didn't stop — what do I do?

Check that you tapped the End fast button. If the issue persists, restart the app.

Does logging a meal end my fast?

No. Logging a meal doesn't stop the fasting timer. When you break your fast, tap End fast in the fasting block.

Today shows "No fasting day" and there is no button to start a fast — why?

Most likely a separate schedule is set for this day of the week. Open the block settings (>) and check your schedule.

Can I remove the fasting block?

Yes. Turn it off in your profile settings: Profile → Nutrition screen sections → Fasting.

Does gelatin break a fast?

Yes.

Does black coffee or plain tea break a fast?

Generally no, but ask the Coach for personalized advice.
