AI Summary

GLP‑1 medications have transformed obesity treatment but can cause patients to lose muscle mass as well as fat, and many regain weight—mostly as fat—after stopping the drugs. Researchers at Northwestern University have developed an experimental RNA therapy that prompts the body to burn more calories. In pre‑clinical testing, the therapy amplified the weight‑loss effects of GLP‑1 drugs, suggesting a way to preserve muscle while enhancing overall outcomes.
