Fat cell number increases through childhood and adolescence and generally stabilizes in adulthood. But this doesn’t mean that fat cells, or adipocytes, are stagnant. The size of individual fat cells is remarkably variable, expanding and contracting with weight gain or weight loss. And as with most cell types in the body, adipocytes die eventually.
"Are Fat Cells Forever?" is from the February 20, 2017 U.S. section of The New York Times. It was written by Alice Callahan and narrated by Kristi Burns.
