F1's Lewis Hamilton has said that he has gradually moved to veganism over the past two years after TV documentary inspired him to do so to improve his health and avoid harming the planet.
Mercedes driver, Hamilton said he had changed his habits after watching a documentary about the environmental impact of the meat industry.
"It is something I have been going towards anyway. I stopped eating red meat two years ago," he told the BBC.
"This year I stopped eating chicken and then kind of went back to it and now I've stopped again. So I have generally been pescatarian for the majority of the year and then I cut out fish too."
He added: "I have actually eaten plant-based food for the last two days and it has been amazing. So far, I don't feel as if I have been missing out. I don't know how easy it is going to be when I get home. That is going to be a real test."
