Brazil football great Ronaldo, who like nearly half of his country's population is overweight, has lost 17 kilograms in three months as part of a television reality show.

Over the past three months the portly ex-striker, now a member of Brazil's 2014 World Cup organizing committee, went through a series of gruelling physical exercises and dietary reeducation aired every Sunday on the Medida Certa (Ideal Measurements) show.
