Most powerful obesity drug yet: People lost up to 25% of weight in trial
Eli Lilly's obesity drug retatrutide showed promising results in a late-stage trial, with participants losing up to 25% of their weight. The drug also reduced knee pain and sleep apnea events. Eli Lilly is developing the drug, which targets GLP-1, GIP, and glucagon. The trial did not compare it to existing treatments, and further studies are needed to assess safety and efficacy. According to the trial data, more than a third of participants lost 30% or more of their weight.
