## Summary

GLP-1 drugs like Ozempic help older adults shed weight, but a lot of that loss can be muscle. This review warns about sarcopenia, the muscle wasting that makes aging riskier. The authors say pairing the drugs with strength training and enough protein may protect muscle.

## Practical Takeaway

This review suggests resistance exercise and enough protein may help preserve muscle during GLP-1 weight loss.
