Daily protein feeding clock
Meal nodes around wake, training, sleep, and overnight recovery
A 24-hour clock sizes each feeding node by grams, highlights the training-adjacent meal, and shades the sleep interval so spacing collisions are immediately visible.
Clock schedule
Feeding times, allocations, and spacing checks
Times are evenly distributed across the entered waking window before the training and pre-sleep allocation rules are applied.
| Feeding | Time | Protein | Hours since prior | Role | Spacing check |

Schedule setup
Start with the real waking window and meal count
- Enter normal wake and sleep clock times.
- Choose a meal count the day can actually support.
- Use minimum spacing as a practical constraint.
- Anchor the training time independently.
- Reserve a pre-sleep allocation only when it suits the chosen plan.
Clock-design logic
A mathematically even schedule can still be operationally poor
Equal spacing is a neutral starting point, not a universal recommendation. The training and pre-sleep rules alter gram allocation while the clock preserves actual time constraints.
When the waking window is too short for the requested feedings and minimum spacing, the model reports the collision rather than silently compressing the standard.
Calculation method
Place a fixed daily total inside a constrained waking window
The waking window is measured across midnight when needed. Feeding times are spaced evenly; pre-sleep protein is reserved first, a training-adjacent premium is assigned, and the remaining grams reconcile across other feedings.
Detailed calculation process and general formulas
Window = mod(Sleep - Wake, 24)Spacing = Window / (N - 1)P_remaining = P_day - P_sleepP_train = min(P_base*(1+B/100), P_remaining)P_total = P_sleep + P_train + sum(P_other)Symbols, meanings, and units

Schedule diagnostics
Four clocks determine whether the plan is usable
The page separates waking capacity, average spacing, training proximity, and overnight interval.
Available window
—Hours from wake to sleep.
Meal cadence
—Average interval between scheduled feedings.
Training meal
—Allocation nearest the entered training time.
Night interval
—Gap from the last feeding to the next day.
Decision takeaway: Reduce meal count or revise the window when spacing is infeasible; do not hide collisions by shrinking labels or ignoring the clock.
Schedule review
When the clock should be rebuilt
- Wake or sleep time changes
- Shift work or travel begins
- Training moves to another time
- Meal count becomes impractical
- Tolerance or clinical guidance changes
Daily schedule evidence
Records that reveal whether the clock is realistic
- Meal timestamps
- Work and commute calendar
- Training log
- Sleep schedule
- Adherence and tolerance notes
Practical applications
Decisions this calculator is designed to support
Early wake with evening training
Five feedings must fit between an early wake time and bedtime, with training near dinner.
What the result clarifies: The clock identifies the training meal and checks the remaining intervals.
Compressed shift-work window
A worker requests many feedings inside a short waking period.
What the result clarifies: The schedule status exposes the spacing collision instead of presenting an unrealistic timetable.
Worked example
Current-input substitution and reconciliation
Model limitations
This calculator organizes a chosen protein target across clock time; it does not establish that target or prescribe meal timing. Shift work, medical conditions, appetite, digestion, medications, and sleep disorders need individualized professional guidance.
Protein Intake Schedule Calculator | Daily Feeding Clock FAQ
What if sleep time is earlier than wake time numerically?
The model treats sleep as occurring later in the 24-hour cycle and wraps across midnight.
Are meals always equally spaced?
Times begin evenly spaced; protein grams are then adjusted for training and pre-sleep rules.
What does a spacing collision mean?
The average interval is shorter than the entered minimum.
Does the clock prove better muscle growth?
No. It is a scheduling visualization, not an outcome guarantee.
