Muscle Loss Risk Score.
Up to 40% of weight lost on a GLP-1 can be lean muscle. This calculator tells you where you stand — and what to change this week.
Result
Fill in the form to see your score.
The score is calculated from medication, weight, resistance-training frequency, and protein intake. Takes ~30 seconds.
What this is
A directional score, not a diagnosis. It weights four things research suggests matter most for muscle preservation on a GLP-1: which medication (tirzepatide produces larger absolute losses than semaglutide), how much resistance training you do, and whether your protein intake is above the 1.2–1.6 g/kg/day window that tracks with lean-mass preservation in trials.
What this is not
Medical advice. Not a substitute for your prescriber, RD, or any clinician. If you're experiencing fatigue, weakness, hair shed, or other symptoms, bring this score — and your actual numbers — to a medical professional.
