Important: this page and the tracker are for record-keeping only. They do not give medical or dosing advice. Always follow the plan your prescriber or pharmacist gave you.
What to log each week
- Injection: date, time, the dose on your prescription and whether it was taken, late or missed.
- Injection site: stomach, thigh or upper arm, and which side, so rotating sites is easy.
- Weigh-in: same day and time each week, in kg or lb, for a fair comparison.
- Measurements: waist and hips every few weeks. They often change when the scale doesn’t.
What to log each day (if you want)
Protein and water intake and any side effects such as nausea, constipation, reflux or tiredness, rated 0 to 5. Patterns become visible after a few weeks, for example nausea that is worse the day after injecting. That is useful information to take to your prescriber.
Why a spreadsheet instead of an app
A spreadsheet is private, it lives in your own Excel or Google Drive, there is no account and no subscription, and you can print exactly what you want to show at an appointment.
A ready-made tracker
The GLP-1 Medication & Weight Loss Tracker logs weekly injections or daily pills, shows “Next in 3 d”, “DUE TODAY” or “OVERDUE”, puts your planned dose steps (as given by your prescriber) next to each logged dose, charts weight, measurements and BMI, and prints a one-page doctor-visit summary. Want to try first? The free GLP-1 Tracker Lite has a dose log and weight chart.
FAQ
Does it work for Mounjaro and Wegovy?
Yes. It works for any weekly GLP-1 injection, and for daily GLP-1 pills. You enter the medicine and the doses your prescriber gave you.
Does it tell me what dose to take?
No. It only records the plan you were given and what you took. Dosing decisions are for your prescriber.
Kilograms or pounds?
Either. Choose kg or lb and the charts and BMI follow.
