## In brief

- A study reports greater lean-body-mass decline with tirzepatide than with semaglutide in routine care.
- The comparison was made using body-composition digital phenotyping.
- The source provided is a nature.com subject feed entry with no summary.

## Why it matters

Loss of lean mass during weight-loss treatment is a clinically relevant side effect, so a head-to-head comparison of two widely used drugs in routine care is useful for clinicians and patients.
