This guy, Mr Uribe, has lost 235 KILOS!! (He's still 335kg)
One inspirational story, he plays to lose 120 kg by 2010. His wife left him two years ago but NOW HE HAS A GIRLFRIEND! :O
"I was impotent before, but now everything's working again. Ask my girlfriend," he said happily, his Guinness World Records certificate hanging on the wall." Amazing!
