Mounjaro (tirzepatide) is prescribed on a titration schedule — you don't start at your eventual dose, you climb to it in steps, usually a few weeks apart. That structure is exactly why a plain weight log isn't enough. Almost everything that happens on Mounjaro — a side-effect flare, a stall, a sudden drop in appetite — lines up with *where you are on the ladder*, not just how many weeks you've been on the medication.
If you search "Mounjaro tracker," you're usually looking for one of two things: a way to keep the dose steps straight so you don't lose track of where you are, or a way to organise weeks of data into something you can actually bring to a GP appointment. This post covers both, built specifically around the Mounjaro titration structure rather than GLP-1 medications generally.
Why Track by Dose Step, Not Just by Week
Mounjaro is prescribed as a titration ladder: you start on a low dose and step up over time, as your prescriber decides. Your own ladder — the dose steps and the timing — comes from your prescriber and the patient leaflet, not from us; we deliberately don't list dose numbers here. What matters for tracking is simply that your log knows *which step you were on* when you wrote each entry.
A week-by-week log treats week 9 and week 13 as unrelated data points. A dose-step log treats them as "week 3 of my third step" and "week 1 of my fourth step" — which is the framing that actually explains what you're seeing. Side-effect intensity, appetite suppression, and weight movement all tend to cluster around the first one to two weeks after a step-up, then settle. Without labelling entries by dose step, that pattern is invisible; with it, it's obvious within a few weeks.
What to Log at Each Dose Step
Each entry in your tracker should carry these fields, whichever dose step you're currently on:
Current dose and step number. Which of the six doses you're on, and roughly how many weeks you've been at that specific dose (not total weeks on Mounjaro). This single field is what makes every other column meaningful.
Injection day and site. Mounjaro is a once-weekly injection. Log the exact day and which site you used (abdomen, thigh, upper arm) — rotating sites is standard injection technique, and if side effects cluster around a particular site, this column reveals it.
Weight, same day each week. Same morning conditions every time: after waking, before food, after the bathroom. Weigh weekly, not daily — tirzepatide weight loss is not linear, and daily weighing mostly captures water weight rather than the underlying trend.
Appetite and "food noise." Rate appetite suppression 1–5 and note whether the mental preoccupation with food — often described as "food noise" — has quieted. Track this separately from weight, because a quiet appetite without a matching change in what you eat won't move the scale.
Side effects, rated 0–5, by dose step. Nausea, constipation, fatigue, reflux, and anything else, scored for severity rather than just noted as present. Tagging each entry with a dose step lets you eventually see "nausea peaked at 4/5 in week 1 of each step-up and dropped to 1/5 by week 3" — a pattern, not a vague memory of "the first couple of weeks were rough."
A free-text note. Anything else — a missed injection, a supply gap, an unusual symptom you're not sure is related.
The Question People Actually Bring to Their GP: "Is This Dose Working, or Is It Time to Step Up?"
This is the single most common thing people on Mounjaro want clarity on, and it's a question a prescriber is far better placed to answer with data in front of them than with a verbal impression.
A dose-step log gives you the material for that conversation without asking you to draw any clinical conclusions yourself:
- How many weeks have you been at your current dose, and has your weight trend flattened, or is it still moving?
- Has your appetite suppression stayed steady, or has it faded since you first reached this dose? (Tracking food noise weekly, not just at the start of a dose step, is what surfaces a fade.)
- Are side effects from this step settling, or are they still at the same severity three-plus weeks in?
- Is there a specific side effect that's limiting what you can eat or do, severe enough that it's worth raising before any decision about the next step?
You're not deciding whether to step up — that's your prescriber's call, informed by your history and their clinical judgement. What the log does is turn "I think this dose might not be doing much anymore" into a documented, week-by-week picture they can actually act on in a 15-minute appointment.
For the fuller picture beyond dose-specific tracking — protein, hydration, and every category worth logging across any GLP-1 medication — see What to Track on GLP-1 Medications (The Full Picture). And if side effects specifically are what's bringing you here, GLP-1 Side Effects: A Simple Log to Bring to Your Doctor covers a focused weekly format for exactly that conversation. If you're tracking the same medication under its US brand name, see the companion post: Zepbound Tracker: A Weekly Log to Bring to Your Doctor.
Get the Free Checklist and Adapt It to Your Dose Ladder
The free GLP-1 tracking checklist covers weight, dose, side effects, and injection day in a printable one-pager. It isn't Mounjaro-specific out of the box, but the dose field is exactly where you'd note your current step — most people using it for Mounjaro simply write whatever dose their prescriber has them on in that column each week.

It's an organisational tool, not a medical one. Print it, fill it weekly, bring it to appointments.
What to Bring to a GP or Specialist Review
Most Mounjaro follow-up appointments run 15–20 minutes. A one-page summary of the last four to eight weeks is more useful than handing over a full log:
- Current dose and how many weeks you've been at it
- Weight at the start of this dose step vs. now, and whether the trend is still moving or has flattened
- Your worst side effect this period, severity, and whether it's improving, stable, or worsening
- Whether appetite suppression / food noise has changed since this dose step began
- Your top question — written down before you go in, not composed in the waiting room
That is the material for the "is this dose working" conversation. A spreadsheet that tags every row with the dose step and auto-builds this summary saves you from reconstructing it from memory each time.
When a Spreadsheet Beats a Notebook or an App for This
A paper log can hold all of the above, but seeing the pattern — nausea clustering in the first week of every step, weight flattening three weeks into a dose — requires flipping back through pages yourself. A dedicated GLP-1 app gives you structure but rarely lets you tag entries by *dose step*, since most are built generically across GLP-1 medications rather than around Mounjaro's titration ladder.
A spreadsheet with a dose-step column, a weight chart, and a side-effect severity view does this automatically, and a well-built one can generate the doctor-ready summary above in seconds. We compare all three formats honestly — including which suits which kind of person — in GLP-1 Tracker: Spreadsheet vs App vs Notebook.
The GLP-1 Weight-Loss Journey Tracker ($15) is a Google Sheets and Excel file built for exactly this: a daily log with an editable dose field so you can track your Mounjaro step directly, 18 side effects rated 0–5, auto-calculating protein and hydration targets from your own weight, weight and measurement charts, an injection-site log, and an auto-populating Doctor Visit Summary formatted for a short appointment.
GLP-1 Weight-Loss Journey Tracker — Everyday Trackers ($15)
Start with the free checklist and tag your dose step manually for a few weeks. If you want the auto-summary and charts once the habit is in place, the full tracker builds on the same structure.
