Weight-loss drugs show signs of slowing biological aging, say drugmakers

Novo and Eli Lilly presented findings at a conference suggesting their GLP-1 weight-loss drugs may slow biological aging. Novo's semaglutide and Lilly's tirzepatide showed reductions in biological age of 2-4 years in overweight or diabetic patients. Both drugs are among the best-selling globally, with Lilly's tirzepatide generating $36B in 2023 revenue. The studies used proteomic and epigenetic clocks to measure aging effects.
