KUALA LUMPUR, Malaysia - Force India driver Nico Hulkenberg has denied being obsessed with weight-loss.On Monday (March 31) Wheels24 reported on a story about Formula 1 drivers dehydrating themselves for GP race weekends. Amid rumours of deliberate dehydration, when it emerged that a driver had passed out in Malaysia, eyes turned to racers like Nico Hulkenberg, who standing at over 1.8m is one of the tallest on the grid.Hulkenberg has revealed he ate McDonalds in Kuala Lumpur: "This was the exception rather than the rule but this was an emergency I was really hungry and needed to have something. There's a McDonald's on almost every corner."'LIVING LIKE A MONK'Hulkenberg said he is not obsessed with his weight in 2014 because, as a tall driver, he has worked hard throughout his career to be as light as possible.Hulkenberg said: "I think some of the other guys had some more weight in reserve that they had to lose. I'm more or less what I was at the end of 2013. I couldn't lose any more."One of the drivers who has lost weight is Mercedes' Nico Rosberg, despite the fact he is at least 6cm shorter than Hulkenberg.Rosberg said: "I had to make the sacrifice if I want to balance the car perfectly. The diet alone is easy, but training with little food is hell."I have eaten no sugar since early December 2013 for my dream I'm living like a monk."Stay with Wheels24 for the 2014 F1 season – fresh reports every day.
