Chi di noi non si è chiesto come perdere i chili di troppo? Per intraprendere una dieta ci vuole costanza, ed è spesso difficile mantenere i risultati ottenuti. La soluzione è più facile del previsto: bastano i brividi causati dal freddo ed un po' di esercizio fisico.
Secondo una ricerca pubblicata su Cell Metabolism, infatti, brividi ed esercizio fisico conducono alla trasformazione del tessuto adiposo bianco, che accumula grassi, nel tessuto adiposo bruno, capace di bruciarli.
L'ipotesi è stata formulata anni fa da uno studio dell'Università di Ancona, ma ora i ricercatori del gruppo coordinato dall'italiano Francesco Saverio Celi, che lavora negli USA al National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), sono stati in grado di confermarla scientificamente.
La perdita di massa grassa potrebbe inoltre rappresentare una misura di prevenzione per l'obesità e addirittura per il diabete.
