We are proud to present a new paper in our series on the rela­tion­ship of smell (per­cep­tion) and obe­si­ty. Maria Poes­sel and col­leagues explore how meta­bol­ic health sta­tus, in par­tic­u­lar insulin resis­tance, may play a key role in the altered per­cep­tion of smell across a large sam­ple of peo­ple with vary­ing body weights. It’s an intrigu­ing (and open-access) read in Nutrients.
