Weight Regain After Stopping GLP-1 Drugs

New research from Oxford University indicates that individuals who stop taking GLP-1 agonist weight-loss drugs, such as Semaglutide, Semaglutide (from Novo Nordisk), Tirzepatide, and Tirzepatide (from Eli Lilly and Company), regain weight four times faster than those who lose weight through diet and exercise alone. The study, which reviewed 37 different weight-loss drug studies, found that participants regained an average of 10kg within a year after discontinuing medication, projecting a return to original weight in 18 months. This rapid weight regain, along with the high cost of these drugs (over $1,000 a month in the United States) and common side effects, contributes to about half of users discontinuing medication within a year. Experts like Susan Jebb and Sam West from Oxford University, and Garron Dodd from the University of Melbourne, emphasize that these drugs are a valuable tool but not a cure, suggesting they may need to be continued for life, which has implications for national health systems' cost-effectiveness assessments.
