Those who take tirzepatide, the drug sold as Zepbound and Mounjaro, could lose more weight than those who take semaglutide, known as Ozempic and Wegovy, according to new research.

Nearly 32% of Zepbound users lost at least a quarter of their body weight, compared with about 16% of Wegovy users. In both groups, weight loss was about 6% lower in men than in women, AP said. Both groups saw health improvements in blood pressure, blood sugar and blood fat levels, too.

A study of two blockbuster weight-loss drugs showed that users of Eli Lilly’s Zepbound lost just over 2 inches more off their waist compared with Novo Nordisk’s rival Wegovy. At 72 weeks, participants using Zepbound saw an average weight-loss reduction of 20.
