Kind: research · Impact: medium

## In brief

- A randomized controlled trial published in Nature Medicine compared people receiving tirzepatide for obesity with and without resistance exercise.
- Participants who did resistance exercise while on tirzepatide lost less lean mass than those receiving tirzepatide alone.
- The paper was published online on 9 November 2026 (doi:10.1038/s41591-026-04752-5).

## Why it matters

Tirzepatide-driven weight loss can include lean mass loss, and this trial suggests resistance exercise may reduce that loss, which matters for how obesity treatment is monitored and combined with exercise.
