Renata Ceribelli
Despite not being as drastic a transformation as other names on this list, presenter Renata Ceribelli lost more than 10 kilos with the whole of Brazil following her saga when she participated in the show Medida Certa, on Fantástico. Shortly after, she gained a little weight again, but she managed to lose it using the knowledge acquired when participating in the program, and today, with a healthier lifestyle, Renata is thinner than ever.
