From GMMLike his Red Bull teammate Mark Webber, Sebastian Vettel has also counted himself out of the calorie-counting regimen of many of their formula one rivals ahead of the 2009 season.With heavy KERS systems complicating the current car-plus-driver weight minimum of 605 kilograms, many grand prix stars have revealed their quest to shed pounds in the race to improve car set-ups by having more chassis ballast to play with.But the German newspaper Bild on Monday revealed that 21-year-old Vettel's 174-centimetre frame currently weighs in at 64 kilograms.When asked about the weight-loss trend ahead of the 2009 season, he said: "I weigh 67 kilos with all my race gear on, and in the winter enjoyed many full dinner courses."And to the Rheinische Post publication, Vettel admitted: "(Since the end of 2008) I have put on four kilos."Former grand prix driver and German-language commentator Christian Danner said the FIA should step in to counter the trend for skinnier grand prix drivers."New rules should be implemented urgently," he told Bild . "It is not right that formula one drivers should be dieting like ski jumpers." photo: Jasper Juinen/Getty Images
