GLP-1 Curve

Your curve, week by week

The projection page tells you what the average trial participant did. This page tells you what you're doing. Log your weight each week and your real line gets drawn over the trial line.

How to read the two lines

The green line is the mean result from the published trial for your medication — STEP 1 for semaglutide, SURMOUNT-1 for tirzepatide, SCALE for liraglutide, OASIS for the oral tablet. The shaded band is roughly where the middle of those trial populations sat. Your line is your own scale readings.

Being under the green line is not winning and being over it is not failing. Trial participants spread widely around that mean, and weekly scale readings move several pounds on water alone. The line is a reference, not a target. What it is genuinely useful for is spotting a flat stretch that has lasted a month or more, which is a real thing worth raising with whoever prescribed the drug.

Weigh yourself the same way each time — same day, morning, after the bathroom, before eating. Consistency in the method matters far more than the number on any single day.

This is a self-tracking tool, not medical advice, and it is not a substitute for your prescriber. Trial curves are group averages from published studies and are 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 your weight is making you anxious or is feeding restrictive eating, it is reasonable to stop using a tool like this one.
