A useful GLP-1 log starts with three things: what you took and when, your weight if you’re following it, and a short note about how you felt. Keep the entries simple enough that you’ll actually make them. The aim is to have a clear record you can look back on.
This approach works for a prescribed semaglutide or tirzepatide routine. You don’t need to record every meal or give every feeling a score. Start with the details you’re most likely to forget.
Record what happened, alongside the plan
A scheduled dose and a dose you’ve taken are different pieces of information. Keep the medicine’s name, the prescribed amount and its unit, and the date you actually took it together. If you inject your medication, noting the injection site can make the next entry easier to understand.
Copy the amount from your prescription or dispensing label instead of relying on memory. “Monday dose taken” is less useful later if the prescription changes and you can’t remember which amount Monday belonged to.
When something changes, add the date and a brief explanation: a new prescription, a delayed dose, or a different product. Record a missed dose honestly and use that medicine’s instructions for what to do next. A blank space shouldn’t look like a dose you took.
Make weight entries comparable
If weight is part of your plan, consistency makes the record easier to read. NHS England’s weighing guide recommends using the same scales in the same place, at the same time of day, preferably in the morning, and wearing similar clothing.
You don’t need several readings a day. The NHS guide suggests regular weekly to monthly intervals; follow any different schedule your care team has given you. Save the date and keep the unit consistent so you can compare entries without converting them.
Read across a series of entries instead of treating the latest number as the whole story. A useful review might be as simple as checking the past month’s weights beside the dates your prescribed routine changed.
Describe symptoms in ordinary words
Nausea, vomiting, diarrhea, and constipation are among the common side effects listed in the Wegovy prescribing information. A short note can capture when a symptom started, how long it lasted, and what it interrupted.
For example: “Tuesday, after breakfast: mild nausea for about an hour. Ate lunch as usual.” That says more than “bad day,” without making note-taking a project. If nothing stood out, you can write that too.
Keep observation separate from explanation. “Nausea the morning after my injection” records timing. “The injection definitely caused it” adds a conclusion the entry alone can’t establish. Our GLP-1 explainer gives some background on the signal these medicines act on.
Some symptoms need action before documentation. The Zepbound medication guide says to stop using it and call your healthcare provider right away for severe abdominal pain that won’t go away, with or without vomiting. Get immediate medical help for trouble breathing or swelling of the face or throat. Follow your own medicine’s safety instructions rather than waiting for a pattern in your log.
Keep a routine you can return to
An entry can be just a few lines: dose taken as prescribed, a weight if it’s your weighing day, and anything you want to remember. Add details when they’re useful; you don’t need to fill every category every day.
In PepNote, log a taken dose directly from your schedule, then open your weight chart to see several weeks at once. You can enter weigh-ins yourself or bring them in from Apple Health.
Once you have a few weeks of entries, look for questions the record helps you ask: when did something begin, what changed around that time, and is it still happening? Keep those questions beside the dates. That gives you something concrete to return to without making tracking the focus of your day.
