Obesity and overnutrition increase levels of reactive sugar- and lipid-derived aldehydes called reactive carbonyl species (RCS). Increased tissue and circulating RCS levels have been tied to insulin resistance and inflammation, but previous pharmacological approaches to target RCS have had equivocal outcomes. In this issue of the JCI, Anderson et al. present evidence for the development and implementation of carnisonol, a compound that is biologically stable in vivo and shows impressive effects on improving metabolism and inflammation in rodent models of diet-induced obesity and metabolic dysfunction.
