THERE’S AN “ABANDONING WHITE FAT PRIVILEGE” JOKE IN HERE SOMEWHERE: How Exercise May Turn White Fat Into Brown. “Exercise may aid in weight control and help to fend off diabetes by improving the ability of fat cells to burn calories, a new study reports. It may do this in part by boosting levels of a hormone called irisin, which is produced during exercise and which may help to turn ordinary white fat into much more metabolically active brown fat, the findings suggest. . . . The results strongly indicate that irisin nudges human white fat to become brown and also suppresses the formation of new white fat, says Li-Jun Yang, a professor of hematopathology at the University of Florida and senior author of the study (which was funded by the scientists themselves). It also seems to promote the formation of bone.”
It’s an in-vitro study, though, so there’s a lot more work to be done.
