Fasting.
How the fasting timer works, what a fast earns, when a fast day counts toward your other goals, and the limits Levelwell puts on long fasts to keep you safe.
The timer
- Goals: tap 12, 14, 16, 18 or 24 hours, or set a custom fast from 1 to 240 hours. The default goal is 16 hours. Settings › Goals shows each goal with its eating window, for example 16 h (16:8).
- The timer shows the time fasted, a bar to your goal and the hours left. It doesn't stop at your goal. Your fast runs until you tap End fast.
- End fast saves the hours, to a tenth of an hour, on the day the fast ended. Reset throws the fast away without saving it.
- Fasting History charts your hours fasted over 7 days, 30 days, 90 days, a year or dates you pick, including the fast running now.
What a fast earns
Any fast of 8 hours or more earns XP for every hour, up to 24 hours, plus a bonus for reaching your goal. It's paid on the day the fast ends and gets your streak bonus.
XP = hours × 8 (hours count up to 24) + 40 if you reached your goal ending before your goal: −30 (not for fasts under 1 hour)
Hours past 24 don't earn more, so a longer fast is never the faster way to level up. Ending early doesn't cost XP when you've already reached today's 14- or 16-hour fast quest.
Quests, challenges and badges
Fasting quests only appear for regular fasters: 3 or more fasts of 12 hours or longer in the last 30 days.
| Reward | Rule | XP |
|---|---|---|
| Daily quest | Complete a 14-hour fast | +70 |
| Daily quest | Complete a 16-hour fast | +120 |
| Weekly challenge | 3 fasts of 14 hours or more | +300 |
| First Fast | A fast of 8 hours or more | +50 |
| Sixteen | A 16-hour fast | +100 |
| Full Day | A 24-hour fast | +300 |
| Fasting Habit | 10 fasts | +200 |
| Discipline | 50 fasts | +700 |
| Monk Mode | 100 fasts | +1,200 |
A fast also ticks the fast item of your activity streak once it reaches 8 hours.
When a fast day counts
On a day you barely eat because you're fasting, Levelwell doesn't hold it against your food goals. A day is a fasting day when one fast covers 20 hours or more of that calendar day. Today also counts when your fast started before midnight and is planned to cover 20 hours of today, or is planned for 24 hours or more.
one fast overlaps the day by ≥ 20 h → fasting day 16:8 rhythm (e.g. 8 PM to noon) → not a fasting day
A fasting day counts as a protein day in the weekly protein challenge and in Trials, and as a logged day for "Log meals on all 7 days". A day that ended a fast of 14 hours or more also counts as a protein day.
Quests during a fast
While a fast is running you get no food quests. Any food quest you haven't finished is swapped for another quest of the same size. Weekly food challenges aren't picked for a week that starts during a fast.
Long fasts
- 24 hours or more: every day the fast touches gets a 25% higher water goal, from the moment a fast with that goal starts.
- 48 hours or more: today's recommended workout becomes a gentle 20-minute mobility session, any program you're following waits, and the Workout tile reads "Easy day". Training anyway still earns XP.
Reminders
During a fast you get a note at the halfway point, one hour before your goal (for goals of 4 hours or more), and when you reach it. You can also ask for a daily reminder to start your fast (off by default, 8:00 PM). It's skipped on a day a fast has already started.
Safety limits
- Levelwell is for adults 18 and over.
- The longest fast goal you can set is 240 hours (10 days).
- A goal of 36 hours or more shows a warning to talk to a doctor first.
- A custom fast of 24 hours or more is blocked when your BMI is under 18.5.
- No Trial ever asks you to fast, eat less or lose weight.
