The latest Hollywood trend isn't a designer brand or a cosmetic procedure - it's GLP-1 medications. Many celebrities have been losing significant weight recently, and it's not just the result of exercise or a healthy lifestyle. While Ozempic is the name most people have heard, it's actually just one brand of medications containing the compound GLP-1, short for glucagon-like peptide-1. This naturally occurring hormone, produced in the gut, helps regulate blood sugar and appetite after meals.
