Charles Barkley is a familiar voice during the NCAA Tournament and his appearance has drawn attention this year. The former NBA star has lost a substantial amount of weight since his post-retirement peak. He has said he used the medication Mounjaro (tirzepatide) and added more consistent, light movement such as golf and gym work. His openness about the reasons for the change has made the transformation a topic of public discussion. Key facts: - At his heaviest after retirement he weighed about 352 pounds. - As of early 2026 he has lost roughly 85 pounds, bringing his weight to about 267 pounds. - He reported losing the first 62 pounds within six months in 2023. - Barkley has said he began taking Mounjaro (tirzepatide), a combined GLP-1 and GIP receptor agonist. - He also increased light physical activity, primarily golf and modest gym work, to help maintain muscle while losing fat. - According to Harvard Health reporting cited in the article, GLP-1 medications act on the pancreas, brain and digestive tract to influence insulin release, appetite signals and gastric emptying. Summary: Barkley's weight change is both visible and publicly discussed, and he attributes it to a combination of prescription medication and lifestyle adjustments. He remains focused on moving closer to his earlier playing weight, with that goal described as ongoing.
