Fat's fate depends on its source

A new study published in Cell Metabolism found that normal metabolism requires so-called "new" fat to maintain glucose, lipid, and cholesterol homeostasis. The researchers discovered that old fat stores alone failed to set critical metabolic pathways in motion, leading to a marked decline in gene activity.
