Lower-dose tirzepatide preserved more muscle mass in 100 lipedema patients

The wire

1. 01Among 100 women with lipedema, both standard and lower-dose tirzepatide escalation cut body weight, fat mass and body fat percentage, with no significant between-group differences in those measures.
2. 02An exploratory responder criterion of at least 5% fat mass loss with under 5% muscle loss was met by 68% of the lower-dose group versus 22% on standard dosing (OR 7.53, 95% CI 3.08-18.44).
3. 03The design was retrospective and non-randomized with unadjusted comparisons, differing cumulative drug exposure and bioimpedance-based body composition estimates; authors call for prospective controlled confirmation.
