Fasting System
Corely fasting is designed to make intermittent fasting easier to follow and easier to understand. It gives users structure, tracks consistency, and ties fasting behavior into the wider coaching system.
How fasting works inside Corely
Fasting is treated as a behavior system. The app helps users stay on plan, understand their pattern, and see how that pattern connects with the rest of their routine.
Schedules
Users can follow structured fasting windows so the day feels intentional instead of improvised.
Consistency tracking
Consistency is often more useful than one perfect day. Corely helps users see whether they are building a repeatable rhythm.
Coaching prompts
The coach layer can reinforce positive habits, respond to early breaks, and keep the user focused on what matters next.
System connection
Fasting becomes more meaningful when users can view it alongside training and nutrition instead of in a disconnected app.
Choose a fasting structure that matches your week
Corely gives fasting a schedule instead of leaving it as a daily decision. You can keep the pattern simple, make it different on specific days, or use a recurring preset when that is easier to follow.
Build a manual recurring plan
A manual plan lets you choose the fasting length, the time that anchors the window, and the days it should run. The anchor can represent when the fast starts or when it ends, which makes the schedule easier to fit around work, family, training, and normal meal times.
- Choose the target fasting length
- Set a start-time or end-time anchor
- Select the active days of the week
- Customize an individual day when the week is not uniform
Use a familiar preset
Preset schedules make common patterns faster to set up. Corely can support daily windows such as 12-hour fasting, 16:8, 18:6, and 20:4, along with patterns such as OMAD, weekday schedules, and longer weekly windows. The point is not to make one schedule look superior. It is to give the user a structure that can actually be repeated.
When the day changes, the schedule can recover with you
A fasting plan is useful only if it can survive ordinary life. Corely is designed so one early meal or changed day does not require rebuilding the entire plan.
Start outside the automatic timing
When you want to begin before the next scheduled window, Start fasting now lets you begin from the current moment where that option is available. Your repeating schedule stays intact, so a one-off decision does not have to become a permanent schedule edit.
Break a fast early without turning it into failure
If you end a fast early, Corely can stop the reminders for that window and return you to the next scheduled fast. That keeps the experience focused on the next useful action instead of treating one changed day as a broken streak.
See fasting as a pattern, not a single timer
The timer tells you what is happening now. Progress tells you whether the routine is becoming repeatable over time.
Fasting trend
In Progress, each daily bar represents fasting hours for that day. The summary can show average fasting duration, how many scheduled windows were completed, and the best duration in the selected range. Comparing the current period with the previous one makes it easier to see direction without overreacting to one day.
Paused schedules stay understandable
If fasting is paused, a gap in the chart is better read as a schedule state, not as a failed streak. Corely separates consistency from perfection so the history remains useful even when travel, illness, social plans, or a deliberate break changes the routine.
Fasting works best as one part of the bigger picture
Corely places fasting beside training, nutrition, and progress because timing alone does not explain how a routine is going. A useful schedule should still leave room for adequate food, hydration, recovery, and the demands of the day. The app helps organize the behavior; it does not diagnose conditions or replace individualized medical guidance.
Fasting is not appropriate for everyone. People who are pregnant or breastfeeding, have a history of disordered eating, use medications affected by food timing, or have a medical condition that changes nutrition needs should get guidance from a qualified healthcare professional before using a fasting routine.
