What was said

"Now, these things are called MASLD and MASH, not the TV show. And what does that stand for? That stands for metabolic dysfunction associated stotic liver disease and stato heepitis. So, basically, it's the same disease, just new names."

Peter Attia says medical nomenclature has shifted from “non-alcoholic fatty liver disease” (NAFLD) and NASH to MASLD and MASH, framing the change as an attempt to reference underlying metabolic dysfunction rather than fat alone. He characterises the rebranding as largely a change in labels rather than in disease biology.
