New Force India driver Esteban Ocon has revealed that he has had to force feed himself in order to prepare for the new Formula 1 season.
The aerodynamic regulations will promp higher cornering speeds, meaning drivers are having to put on extra weight in order to cope with the increased physical demand on their bodies.
Ocon, though, has been forced into extreme lengths as he tries to meet to new required weight.
"I was on a big protein diet, it was very hard, I had to force feed myself," Ocon said.
"And now I stopped so I lost like 500g, something like that.
"It's been very hard, I've been doing nine hours of cardio per week, 10 hours of gym and all the rest was reaction training, circuit training… very hard stuff."
Ocon was also asked whether his weight had been this much of an issue before the start of a new season.
"Not really," he added. "Last year I was on the limit of the weight, even though I'm very skinny.
"This year there is no restriction at the moment and the team agreed it was more important to feel good in the car than be underweight and not be able to drive the car.
"Everything is stronger. I really improved on that aspect [the weight].
"Cardio, I went biking with some friends that were following me before and now they just can't follow me anymore. So I'm very happy with the progress."
