03BACKGROUND

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.

04DEEP DIVE

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.
