Are Weight-Loss Drugs Also Longevity Drugs? [View all]

Two of the hottest trends in health — longevity medicine and weight-loss drugs — are colliding.

A theory that GLP-1 medications like Ozempic or Zepbound might help people live longer has been bandied about by biohackers and aging researchers for several years. Online pharmacies already market compounded versions of the drugs to purportedly extend health span. But so far, academic research into the hypothesis has been scant.

One of the first studies putting the idea to the test was published last month. It showed that, among people with H.I.V. and lipohypertrophy (fatty deposits that develop under the skin), taking semaglutide (the drug in Ozempic) for eight months seemed to slow participants’ biological aging, according to blood tests that measure age-related biomarkers. People with H.I.V. experience accelerated aging because of the infection, so they are a good population in which to conduct age-related research, said Michael Corley, an associate professor of medicine at the University of California, San Diego’s Stein Institute for Research on Aging, who led the study.

The trial was preliminary, but it “provided us an opportunity to say, hey, is there any signal here that warrants all the hype?” Dr. Corley said.

That hype stems from several lines of evidence. First, there is ample research demonstrating that GLP-1s improve people’s metabolic health by helping to regulate insulin and blood sugar levels and causing weight loss. Several studies show that they also benefit cardiovascular, liver and kidney health.
