University of Pennsylvania Study Highlights Risks of Inconsistent GLP-1 Medication Use for Weight Loss
Researchers at the University of Pennsylvania have conducted a study indicating that inconsistent use of GLP-1 medications, such as semaglutide, may lead to weight gain rather than loss. The study, conducted in the Leung Lab, involved cycling mice on and off semaglutide over a four-month period. The findings revealed that mice subjected to intermittent use of the drug gained weight, primarily in the form of fat, even after resuming consistent use for 62 days. This suggests that the drug's effectiveness diminishes with inconsistent use. GLP-1 medications are popular for weight loss, with about one in eight adults using them. However, more than half of users discontinue the medication within two years, often restarting later. The study raises concerns about potential similar effects in humans, although further research is needed to confirm this.
