Lewis Hamilton claims that it is "absolute rubbish" that he has lost muscle mass because he doesn't eat meat anymore.
Last year Hamilton spoke out for the first time about his decision to embrace a vegan lifestyle.
The Mercedes driver urged others to follow his path, advocating that it is one way to help save the planet.
Not everyone applauded him.
The Brit was labelled a hypocrite by Fernando Alonso while fans also had a go at him given Formula One's gas-guzzling exploits.
Hamilton brushed it all aside and proved that swapping to a
plant-based diet had not in any way impacted his physical health as he
romped to a sixth World title.
Speaking to the media in Melbourne prior to the cancellation of the Australian GP, he once again defended his choices.
“I think my health has just got better and better over the last

physically, it’s just enabled me to ... you know people do think you’re
going to lose muscle if you don’t have your protein, that’s ... a lot of
the time people say I need my protein but it’s absolute rubbish. You
just need to do some reading online.
“I’ve managed to ... last year I bulked up, I put a lot more weight on.
This winter I trimmed down, like cut but have more muscle and I’m able
to lift more weight than I’ve ever done before and I haven’t been able
to run further than I’ve ever been able to run before. That’s just
enabled me to train better.
“But you’ve seen it in other sports, other sportsmen and women around
the world are trying these things. Serena [Williams] has been working
on it, (Novak) Djokovic, you’ve got a bunch of people out there that are

there are lots of areas that need to ... not just in food but there’s a lot
of things that we all need to do better moving forward but one step at a
Last year Hamilton appeared in a documentary called ‘The Game
Changers’, which also featured Novak Djokovic and Arnold Schwarzenegger.
