‘Godzilla’ of weight-loss drugs could provide other important health benefits
Eli Lilly's retatrutide, a weight-loss drug targeting GLP-1, GIP, and glucagon, showed significant weight reduction and improved blood sugar levels in a global trial. The 80-week study with 2,047 participants found average weight loss of 11.9% to 18.8% across different doses, with 47% of the highest dose group losing at least 20% of their weight. The drug also improved cardiometabolic risk factors but had gastrointestinal side effects.
