Your curve, week by week

The projection page shows what the average trial participant did. This page shows what you're doing. Log your weight weekly and your real line is drawn over the trial line.

Set up your curve

How to read the two lines

The blue line is the published trial mean for your medication and maintenance dose: SURMOUNT-1 for tirzepatide 5, 10 or 15 mg, STEP 1 for semaglutide 2.4 mg, STEP UP for Wegovy HD, OASIS 4 for the Wegovy pill, ATTAIN-1 for Foundayo and SCALE for liraglutide (the same curves as the curve calculator). The shaded band is an illustrative 0.55–1.35× of that mean, not a clinical range (see Methods and sources). Your line is your own scale readings.

Under the blue line is not winning; over it is not failing. Trial participants spread widely around the mean, and weekly readings swing several pounds on water alone. The line is a reference, not a target.

Its real use is seeing your own trend over several weeks. If you have questions about your trend, your dose or how you feel, your prescriber is the person to ask.

Weigh the same way each time: same day, morning, after the bathroom, before eating. A consistent method matters more than any single reading.

This is a self-tracking tool, not medical advice or a substitute for your prescriber. Trial curves are group averages from published studies, not a prediction for any individual.

Nothing here is a reason to change, skip, or adjust a prescription; those decisions belong with a licensed clinician. If tracking makes you anxious or feeds restrictive eating, it is reasonable to stop.

A weekly GLP-1 email

One short email a week on GLP-1 treatment: what the trials and prescribing labels describe at each stage, and changes in cost and access. General information, not tied to a particular medication or dose. For the trial average for your own medication, use the curve calculator.
