Top athlete - and recent vegan - Lewis Hamilton is getting close to clinching his fourth Formula 1 title after a blistering win today.
Hamilton now has an extremely good chance of winning the F1 title at his next race after today's performance in the United States Grand Prix.
The star recently transitioned to a vegan diet after watching documentary What the Health.
Hamilton made the announcement that he'd gone vegan on Snapchat - saying that animals, his health, and the planet all motivated his choice.
Speaking later about the move, he said: "Every person I have met who has gone vegan says it is the best decision they have ever made.
"When you watch this documentary and you see meat clogging up your arteries, you see all the stuff they put in the meat, stuff we are all eating, there is no way I am going to disregard that."
Following today's victory, the star says he feels the best he ever has - and has pledged to stay plant-based.
Losing his edge?
But there was some controversy around his new diet some weeks ago, with performance biochemist Dr Rob Child telling BBC Sport: "I think it is a bad idea to switch mid-season.
"Quite often changing a diet does throw up some issues that take some time to resolve. Ultimately during that period his performance could be compromised.
"It is a close battle in the championship and you are looking to gain every advantage you can wherever possible.
"Such changes are made during the off season with the athletes I work with rather than during the season."
However, the racer's recent performance suggests such speculation is off the mark.
Hamilton is now 66 points clear of the second-placed Sebastian Vettel, with only 75 points up for grabs in the remaining three races.
Several pundits are predicting Hamilton will take the title at his next race - the Mexican Grand Prix.
Speaking after his win today, Hamilton said: "Since 2012, this crowd has been growing year-on-year.
"I think now this track is my favourite track. I loved the swing of the corners today.
"A big congratulations to the team, who have worked so hard at the factory."
