Clinical Sarcopenia Algorithm
GLP-1 Sarcopenia & Lean Mass Loss Risk Calculator
In STEP-1 and SURPASS trials, 25% to 40% of total weight lost on GLP-1 receptor agonists was lean skeletal muscle. Use this tool to calculate your catabolic vulnerability.

CRITICAL RISK: High rate of lean tissue wasting
Estimated Muscle Catabolized
~2.1 kg per month
At this trajectory, muscle mass represents 38% of your weight drop.
Prescribed Intervention:
Raise daily protein floor to 153g/day (currently 98g deficit).
Distribute into 30g–40g leucine-dense boluses across 4 eating windows.
