What to Log in Your First Month on GLP-1
The handful of things worth recording when you start GLP-1 treatment — and what you can safely skip, because over-tracking is what makes people quit in week three.
Start smaller than you think
The instinct on day one is to track everything: every meal, every symptom, weight every morning, water, steps, sleep. It is thorough, it feels responsible, and it almost always collapses somewhere in week three — usually right before the first dose increase, which is when the record becomes genuinely valuable.
A small log you actually keep beats a comprehensive one you abandon. Everything below is chosen on that basis.
The five things worth logging
Your baseline, once. Starting weight, starting dose, start date, and a sentence on why you are doing this. You will not remember the last one accurately in six months, and it is the entry people most often say they are glad they wrote.
Every shot. Date, dose, injection site. Three fields, a few seconds, and it is the backbone of everything else. A dose log with gaps in it cannot be repaired later.
Side effects, same day. What it was, how bad on a 1-5 scale, how long. Recording severity the same day is what makes it comparable — a rating reconstructed a week later is a guess.
Weight, weekly. Same day, same time, same conditions. Daily weighing in month one is the fastest route to reading meaning into normal fluctuation and feeling terrible about it.
Food, only when something happens. Not a full diary. Log the meal that preceded bad nausea, and log what you managed on the days you could not face eating. Those two are the entries you will actually refer back to.
What to skip
Steps, sleep, macros, calories, measurements, photos — not because none of it matters, but because none of it is what your first dose review will turn on. Add one of them later if a specific question comes up. Starting with all of them is how the log dies.
Why month one is not about results
Worth setting expectations before the first weigh-in disappoints someone.
The starting dose is not meant to be therapeutic. It exists so your body can adjust, and the plan is to step up from it — that is what titration is. On top of that, levels of the medication keep climbing for roughly four to five weeks after you start before they plateau, so even the starting dose is not fully "on" for most of month one. The half-life explainer covers why.
So month one is not measuring whether the treatment works. It is measuring whether you tolerate it, and whether this dose is a sustainable base to increase from. Those are the questions your first review will actually turn on, and they are answerable from a very small log.
A useful side effect of knowing this: a flat or erratic first month is not a signal. Neither is a dramatic one.
The three questions month one is answering
Everything above exists to answer:
- How do I respond to this medication at the starting dose?
- Are the side effects settling, or getting worse?
- Is this dose sustainable enough to step up from?
Your provider will ask some version of all three at the first review. Answering with specifics rather than an impression is the entire point of the exercise.
What is normal, and what is not
Side effects are common when starting, and commonly ease over the first weeks at a stable dose. Weight change in the first month is highly variable and is a poor predictor of anything.
None of that means you should wait things out. Contact your provider promptly about severe or persistent abdominal pain, repeated vomiting, signs of dehydration, or anything worsening rather than settling — and follow the guidance that came with your medication. Tracking is for understanding the ordinary; it is not a reason to sit on the serious.
What to add in month two
Once the first month's habit has survived, there are three additions worth making — one at a time, not all at once.
The day of the shot cycle, on every symptom entry. If you are not already doing this, it is the highest-value single field in the whole record. It is what turns a list of bad days into a visible pattern, usually within two or three cycles. The day-by-day timeline covers the shape you are looking for.
Appetite or food noise, as a 1–5 rating. It moves faster than weight and tells you more about what the dose is doing. One number a day.
Protein, roughly. Not a food diary. Just enough to know whether you are near your target or nowhere near it, which is the only distinction that matters at this resolution — see protein targets on GLP-1.
Everything else can keep waiting. Measurements, photos and body composition become interesting around month three, when there is enough time elapsed for them to say anything; the muscle tracking guide covers them when you get there.
Set it up in five minutes
Record your baseline. Pick your shot day. Decide where the log lives — app, notes, paper, whichever you will genuinely open. Then log the first shot the moment you take it.
That is the whole setup. The system that survives month one is always the one that took five minutes to start, not the one that took an afternoon.
If you are choosing where it lives, the honest answer is that paper works, a spreadsheet works, and an app works — and the differences only start to matter around month three when you begin asking questions across time. Those trade-offs are covered in paper log, spreadsheet and the tracker comparison. Do not spend week one optimising this. Spend week one logging.
