Your first month on a GLP-1: what's worth writing down

The first month on a GLP-1 medication is less about results and more about gathering signal. Your body is meeting a new routine, and almost everything you'll want to know later — how a dose change felt, which days were rough, whether you're actually eating enough — depends on having written something down while it was happening.

You don't need a research notebook. You need a handful of fields you can fill in without thinking, on days when thinking is the last thing you want to do.

The short list

• When you took it, and which dose. Timing drifts more than people expect, and the drift matters when you're reading patterns later.
• Where the shot went, if you inject. Rotating sites is easier when you can actually see where the last one was.
• How you felt — and roughly how strongly. A quick 0-to-rough scale beats a paragraph you'll never write.
• Whether you ate enough protein. Not the full meal breakdown. Just: did the day add up, or not.
• Water. It's the cheapest variable to fix and the easiest to ignore.

Weight belongs on the list too, but with a lighter touch. Weigh on your own schedule, not daily, and treat the trend as the truth instead of any single morning.

Why a single line helps

Scattered notes hide the relationships you most want to see. The connection between a dose increase and a hard Tuesday only shows up when both live on the same timeline. That's the whole idea behind keeping a dose, a meal, and a symptom on one line instead of three apps.

Month one isn't graded. It's just the data your future appointments will wish you had kept.

If you take nothing else from this: be consistent over being thorough. Five fields logged every day will teach you more than twenty fields logged when you remember.
