How To Use This Calculator

This page turns trial averages into rough planning benchmarks. It does not predict your exact result, and it should not be used as a promise of what you will lose.

Your result can be higher or lower depending on dose, adherence, side effects, activity, food intake, and your own physiology.

Use the benchmark alongside your weight trend and your clinician's guidance so the target stays realistic.

How To Use This Calculator Effectively

The most useful number here is the benchmark you compare against your real trend. If your pace is much faster or slower, the next step is to look at dose, adherence, appetite, and total intake.

If you are losing weight quickly, make sure you are still getting enough protein, fluids, and sleep. If you are not moving at all, bring your log and your medication history to your clinician rather than increasing the dose on your own.

Recheck the benchmark any time your medication dose changes or your body weight moves enough to shift the comparison.

Calculator FAQs

Estimate weight-loss benchmarks for Ozempic, Wegovy, and Mounjaro using published trial averages.

Yes. Shotlee supports tracking doses, side effects, and health metrics. It is free.

The calculator is accurate as a trial-benchmark reference, but individual results vary widely. Use it as a planning tool, not a guarantee.

Recalculate after a dose change or after your body weight shifts enough to make the benchmark comparison less useful.
