Qualche chilo di troppo non è nocivo per la salute: anzi chi è in leggero sovrappeso sarebbe più al riparo da morte prematura.
Lo indicano i risultati di uno studio pubblicato dal Journal of American Medical Association. I vantaggi riguardano soprattutto chi ha più di 60 anni e le persone che soffrono di malattie croniche. Il motivo non è chiaro: emerge da indagini nel mondo che hanno coinvolto 3 milioni di persone.
Chi ha accumulato qualche chilo di troppo in questo periodo non deve quindi sentirsi in colpa ma nemmeno questo deve essere un alibi per ingrassare ulteriormente: se infatti superare leggermente il peso forma fa bene, l'obesità è invece dannosa e accorcia sensibilmente l'esistenza.
