La dieta può essere positiva non solo per chi la segue, ma anche per il partner. Secondo i ricercatori dell’università del Connecticut esiste un vero e proprio fenomeno di "dimagrimento a catena", che coinvolge entrambi.
La ricerca, pubblicata sulla rivista scientifica Obesity, ha coinvolto 130 coppie monitorate per sei mesi, e si è scoperto che quando un membro di una coppia si impegna a perdere peso, anche l'altro automaticamente fa altrettanto, pur senza partecipare direttamente al percorso dietetico.
Un terzo partecipanti allo studio infatti ha perso il 3% o più del proprio peso corporeo. Inoltre, la modalità con cui si perde peso è interconnessa. Ovvero: se uno dei due è dimagrito con ritmo costante, lo stesso è successo al partner.
"Il modo in cui modifichiamo le abitudini alimentari e l'esercizio fisico può influenzare gli altri in modo positivo o negativo", dice Amy Gorin, psicologa comportamentale e ricercatrice principale dello studio.
