Where this fits

What this sits alongside

Your prescriber decides what changes and when. Nothing here suggests a change, and nothing here is a reason to make one. All this does is mark the date so the weeks either side can be compared honestly instead of from memory.

Why this is hard to keep track of

  • The rough patch and the new normal blur together within about ten days
  • Reviews ask how it went, and memory answers with the worst afternoon
  • Nothing marks the boundary, so there's nothing to compare either side of
  • Improvements are gradual and therefore invisible without a before

Worth recording

  • The date something changed. That single field does most of the work
  • Meals and appetite, at whatever detail you can manage that week
  • Side effects, with severity and how long they lasted
  • How the week felt overall, in your own words

Cadence

Mark the date, then carry on logging as normal

In practice

Say it once, or photograph it

The entries most worth having are the ones made at the exact moment nobody wants to fill in a form. A sentence — typed, dictated, or replaced entirely by a photo of the plate — is a much lower bar, and it carries the context a calorie field would have thrown away.

Titration Weeks Chat

Started the new prescription on Monday. Rough since Wednesday — tired, queasy most afternoons, not eating much.

  • mark_change(kind: "prescriber_change", at: "2026-08-10")
  • log_symptom(type: "nausea", severity: 3, part_of_day: "afternoon")
  • log_note(text: "tired, appetite very low since Wednesday")
  • compare_periods(around: "2026-08-10", window: "14d")

Marked, and I've set up the comparison. So far, four days in: eating occasions are averaging 1.5 a day against 2.6 in the fortnight before, and you've logged nausea on three of four days against twice in the previous two weeks. I'll keep the comparison running for the rest of the fortnight.

Every figure here was counted from entries you made. The model chose which tools to call — it doesn't score the meal, estimate calories from a photo, or decide what any of it says about you.

And then ask

The question the log can answer

Months of entries hold real answers to the things you've been guessing at, and reading them properly has always meant a spreadsheet and a free evening — which is exactly what nobody has.

Ask in plain language. The answers come back with the counts behind them, including when those counts are too thin to mean anything yet — which is the more useful answer far more often than people expect.

Asking about the pattern Chat

How did the last change compare to this one?

Called 3 tools

  • get_history(topic: "titration-weeks", window: "6m")
  • find_pattern(group_by: "context")
  • compare_periods(metric: "entries")

Two changes on record. After the first: nausea on nine of 14 days, average severity 3.1, eating occasions down 22%, back to baseline by day 12. After this one so far: nausea on seven of 11 days, average 2.4, eating occasions down 38%. Side effects look milder this time; the drop in eating is larger and hasn't recovered yet. Both halves are worth mentioning.

Counts and averages over your own entries, nothing more. Where the data is confounded or too thin, the answer says so instead of rounding it into a conclusion.

What it does

Set up around titration weeks

The same mechanics as everything else here, pointed at what actually matters for this one.

An entry survives a bad week

A sentence, or a tick that a meal happened at all. On the weeks when eating is genuinely hard, the log has to cost less than the meal did — otherwise the record stops exactly when it gets interesting.

Photos, for the thing descriptions miss

Portion sense recalibrates within weeks and nobody can see it happening. Two photographs eight weeks apart settle it instantly.

Mark the date something changed

Your prescriber decides what changes; the log just notes when, so the fortnight either side can be counted against each other instead of recalled.

Side effects with the meal before them

Nausea on its own is a complaint. Nausea with what you'd eaten, how long it lasted and where it fell in the week is something a clinician can work with.

Watching for eating too little

The risk here is rarely eating too much. Missed meals and meals without a protein source are counted and shown to you, because appetite has stopped being the thing that would have told you.

Formatted for the review

Export the window you were asked about, photos included, and take it in. It's the answer to the first question at every appointment.

The reason a lot of people start

Something to actually bring to the appointment

You get fifteen minutes, and the first question is always some version of "so what does a normal week look like?" — which nobody on earth can answer accurately from memory.

What this gives you: A clean before-and-after around each change, counted rather than recalled, which is exactly the comparison a review is trying to make.

  • Export the date range you were asked about, as a file you can print
  • Photos alongside the entries, which say more than any description
  • Counts and timings rather than an impression of the worst week
  • Nothing shared anywhere unless you choose to share it

What it won't do

  • Score a meal, or sort food into good and bad
  • Estimate calories from a photo and present the guess as a number
  • Set you a calorie target, a macro target, or a weight
  • Run a streak you can break, or tell you that you've fallen behind
  • Comment on your body. The photos here are of food
  • Diagnose anything, or suggest that a pattern is a diagnosis

It's a notebook that can do arithmetic and answer questions about itself. Deciding what any of it means is a job for you and the people advising you.
