GLP-1 Weight Loss Projection

See your projected weight loss timeline based on clinical trial data for your medication.

Based on Clinical Trial Data

Projections are based on published clinical trial results (STEP, SURMOUNT, SCALE, SUSTAIN, LEAD trials). Individual results vary significantly based on diet, exercise, genetics, and adherence.

Important — Not Medical Advice

This projection is based on population-level clinical trial averages and does not predict your individual outcome. Actual weight loss depends on many factors including diet, exercise, genetics, and medication adherence. Always follow your prescriber's guidance.

What This Projection Models

The Weight Loss Projection uses median outcomes from STEP, SURMOUNT, and SUSTAIN clinical trials to estimate a realistic weight curve based on your starting weight, target, and chosen GLP-1 medication. It shows median, lower-quartile, and upper-quartile trajectories so you have a band of expected outcomes — not a single number.

Who Is This For?

GLP-1 users at any stage who want a realistic comparison point. People often expect linear loss; real trial data shows fast initial loss, mid-curve plateaus, and a long maintenance phase. This tool helps you spot when you are tracking ahead, on target, or behind.

Frequently Asked Questions

How much weight can you lose on Ozempic?

STEP trials show ~15% body weight loss at 68 weeks on the highest dose semaglutide. Real-world results are typically lower — 8 to 12% — due to dose changes and adherence.

Is Mounjaro better than Ozempic for weight loss?

In SURMOUNT-1, tirzepatide (Mounjaro/Zepbound) showed ~21% weight loss at 72 weeks at the highest dose, compared to ~15% for semaglutide. Individual response varies.

Why am I losing weight slower than the projection?

Trial averages assume max dose, full adherence, and lifestyle changes. Plateaus, dose reductions, side effects, and stress all slow real-world loss.

Will I keep the weight off?

Studies suggest most people regain a substantial portion of lost weight within a year of stopping a GLP-1. Maintaining loss requires ongoing medication, habits, or both.
