What to track if you're on a GLP-1

The handful of metrics worth recording on a GLP-1 — beyond the scale — and how to turn a few weeks of notes into something useful for your doctor.

Most people on a GLP-1 track exactly one number: body weight. It's the least informative one available on a weekly basis. Weight is noisy — hydration, sodium, sleep and the time of day move it more than anything meaningful in a seven-day window — and it tells you nothing about the things that actually determine whether you can sustain this.

Track these instead (or as well)

Waist measurement, weekly. Far less noisy than weight and a better reflection of composition change over months.
Protein intake, roughly. You don't need to weigh food. Even a 1–5 rating of "did I get enough protein today" is enough to spot the weeks where you didn't.
Strength or activity. One or two simple markers. Preserving muscle while appetite is suppressed is the whole game, and it's invisible on a scale.
Side-effect intensity. A simple 1–5 for nausea, reflux or fatigue. Patterns here are what your clinician most wants to see.
Hydration and fibre. Two of the most common reversible causes of feeling terrible on a GLP-1.
Sleep quality. One number, same scale, every day.

Weigh yourself properly or not at all

If you're going to track weight, control the conditions: same day of the week, same time of morning, same state, once weekly. Then read the trend line rather than the reading. A single weigh-in is almost meaningless; four in a row point somewhere.

Log the skips

Gaps are the most under-appreciated data in any log. A recorded skip tells you and your clinician something; a missing entry just makes the record untrustworthy. If something was missed, mark it as missed.

Turning notes into a conversation

The reason to keep any of this is the ten minutes you get with a clinician. Arriving with a dated record — what you took, what you skipped, how side effects trended, what your waist did over eight weeks — changes the quality of that conversation completely. It's the difference between a subjective account and a reviewable record. Exporting it as a PDF beforehand is worth the thirty seconds it takes.

One honest caveat

Tracking is not treatment. Nothing you record replaces medical supervision, and no app — including this one — should be telling you what to take or how much. What a log does is make you a better-informed participant in your own care. If you want to read up on the compounds themselves in plain English, the reference library covers the GLP-1 category alongside everything else.

FAQ

What should I track on a GLP-1 besides weight?

Waist measurement weekly, rough protein intake, a strength or activity marker, side-effect intensity on a 1–5 scale, hydration and fibre, and sleep quality. These explain far more than the scale does week to week.

How often should I weigh myself?

Once a week under the same conditions — same day, same time of morning, same state — and read the trend across several weeks rather than any single reading.

Why does logging skipped days matter?

A recorded skip is useful information for you and your clinician. A silently missing day makes the whole record unreliable.
