What to Log in Your First Month on GLP-1

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.

The three questions month one is answering

Everything above exists to answer:

1. How do I respond to this medication at the starting dose?
2. Are the side effects settling, or getting worse?
3. 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.

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.
