GLP 1 medication extends lifespan in mouse study

New research published in Nature shows that the popular weight loss drug semaglutide could do more than trim waistlines. In a study conducted by University of California, Berkeley scientists and reported by Scientific American, elderly mice given the medication lived about 12 percent longer than their untreated peers. The older mice also demonstrated improved physical strength, sharper memory, and better blood sugar control.

For decades, researchers have observed that severely cutting calories can slow down aging, but few people can stick to such strict diets. This experiment suggests that GLP-1 drugs might replicate the biological advantages of fasting without requiring extreme willpower. Interestingly, the mice taking semaglutide performed even better on cognitive tests than those on a restricted diet, hinting at benefits that go beyond simple weight management.

It remains unclear whether taking a GLP-1 drug is more effective for longevity than traditional calorie restriction, or how well these findings will translate to humans. Furthermore, if these drugs actively protect brain function alongside metabolic health, healthcare systems may eventually need to reconsider whether weight loss medications should be prescribed as preventative treatments for age related decline.
