Is this trial a fit for you?

Likely a good fit

Adults 18+ with obesity (BMI > 30 kg/m²) who are already using a GLP-1 receptor agonist and do not have diabetes.

Probably not a fit

Patients who do not experience significant weight loss or who have preexisting muscle disease may see little to no benefit in muscle-related outcomes.

What this trial studies

This prospective, descriptive study follows non-diabetic adults with obesity who are starting a GLP-1 receptor agonist as part of routine care. Researchers measure muscle mass, strength, and physical performance at baseline and after three months, and relate these changes to weight loss. Assessments include SARC-F screening, handgrip strength, chair stand test, gait speed, and bioelectrical impedance analysis for body composition, using data from clinical records. No experimental treatment is assigned; the GLP-1 RA is prescribed by the treating physician. The goal is to understand how weight loss with GLP-1 RAs impacts sarcopenia risk and muscle health.

Why it matters

Potential benefit: If successful, the study could clarify whether GLP-1 RAs lead to meaningful muscle changes and help guide monitoring of muscle health during obesity treatment.

How similar studies have gone: Previous work suggests weight loss strategies can affect muscle mass; this study adds focused, non-diabetic obesity data on GLP-1 RA–associated body composition changes.
