Elevations in branched-chain amino acids (BCAAs) associate with numerous systemic diseases, including cancer, diabetes, and heart failure. However, an integrated understanding of whole-body BCAA metabolism remains lacking. Here, we employ in vivo isotopic tracing to systemically quantify BCAA oxidation in healthy
