Many weight logs fail to show a trend—not because you weigh too seldom, but because conditions change too much between weigh-ins: sometimes before meals, sometimes after; sometimes right after exercise or right after waking; units may even mix jin and kilograms. To make weight data truly useful, build a stable, repeatable minimum plan you can sustain long term.
Use “once a week + one fixed scenario.” For example weigh every Monday morning before breakfast, write “5.2 kg”, and add one line of context in the same entry: mood and appetite, recent diet changes, medication, etc. After three months, even at weekly cadence you can still see whether weight drifts up, down, or swings abnormally.
Keep a fixed template: date | weight (kg) | weighing scenario | one-line note. Example: 2026-04-16, 5.2 kg, before meal, one week into a diet transition. Once the template is stable, list views surface changes at a glance—you don’t need to open every detail to understand what happened.
Judge anomalies by trend first. A single swing does not always mean trouble, but two or three consecutive moves in the same direction (for example steady loss) should be read together with appetite, energy, stool, and activity. That is when weight logs pay off: they give a credible timeline so you can decide sooner whether to see a vet or adjust feeding.
Key points
- Use one unit only: kg (do not mix jin).
- Fixed scenario: weigh at the same relative time before meals when possible.
- Fixed template: avoid vague titles like “today’s note.”
- When something looks off: consecutive change beats one-off noise.
