Food intake varies from one day to another. The US National Cancer Institute explains that two or more non-consecutive 24-hour recalls are required to estimate distributions of usual dietary intake.
The number at a glance
One day is a point. Several days begin to form a pattern.
Research estimating usual intake distributions uses multiple non-consecutive days.
Why days vary
Weekdays and weekends can look different.
Workdays, days at home, and meals with other people create different schedules and choices. One person’s intake is not constant.
A one-day record can describe that day well. It does not automatically describe the person’s long-run average.
Patterns need kindness
A gap does not erase the value of the record.
Even without every meal, several days can reveal staple-heavy days, restaurant days, and days with more vegetable dishes.
The ability to start again after missing a day creates a longer and more honest record than demanding a perfect streak.
What to keep
Do not grade one day. Place different days next to each other.
How MorselFlow fits
MorselFlow is built around a timeline, not a daily score.
Meal photos appear in chronological order. If you miss a day, you can simply begin again with the next meal.
It is a record designed to preserve day-to-day differences and make them easier to review gently.
