About 42% of U.S. adults are obese, the CDC says. GLP-1 medications have changed the picture for people hoping to reduce risks with obesity.

President Joe Biden’s proposal to have GLP-1 weight-loss drugs such as Wegovy, Ozempic, Zepbound and Mounjaro covered by Medicare and Medicaid would help tackle the public-health crisis of obesity, but it would raise the costs for the government programs by billions of dollars per year.

The Biden administration is proposing Medicare and Medicaid coverage for glucagon-like peptide 1 receptor agonist (GLP-1 RA) obesity medications like semaglutide (Wegovy) and tirzepatide (Zepbound), challenging a two-decade-old law and facing probable opposition from the incoming Trump administration.
