As obesity has risen in the United States and all around the world, so too have many other obesity-related health conditions: diabetes, heart disease, stroke, cancer, and maybe even Alzheimer’s disease. But how exactly do those extra pounds lead to such widespread trouble, and how might we go about developing better ways to prevent or alleviate this very serious health threat?

In a new study in Science Translational Medicine [1], researchers performed sophisticated analyses of the molecules excreted in human urine to produce one of the most comprehensive pictures yet of the metabolic signature that appears to correlate with obesity. This work provides a fascinating preview of things to come as researchers from metabolomics, microbiomics, and a wide variety of other fields strive to develop more precise approaches to managing and preventing disease.
