Mercedes F1 driver Lewis Hamilton is one of the executive producers of ‘The Game Changers’ documentary on vegan diet in superstars.

Hamilton moved to plant-based diet in the last few years, having taken up veganism after years of eating meat since his childhood. Since then, the reigning F1 champion has positive words about his new diet and benefits from it in his normal life.

Hamilton has shared plenty of photos and videos on his social media to advocate veganism, like many other athletes. In line with his new style, Hamilton has come on board as an executive producer of a new documentary ‘The Game Changers’.

The British racer also features in the documentary, which has executive producers like James Cameron, Arnorld Schwarzenegger, Jackie Chan, Novak Djokovic and more, while it is being directed by Louie Psihoyos and produced by James Wilks and Joseph Pace.

The global premier of The Game Changers is scheduled for September 16, with a note from Wilks on the documentary states as: “As a combatives instructor for the US military (including the US Marines, US Army Rangers, and US Navy SEALs), as well as a former UFC fighter, I see the human body as a powerful machine with the potential for excellence in many areas, including strength, speed, stamina, and recovery.

“Until I got badly injured while training in 2011, I never thought this potential had much to do with food, which I saw mainly as just calories and protein. But, unable to train for six months after my injury, I started researching the optimal diet for recovery and stumbled across a study about the Roman gladiators which concluded that they ate little or no meat.

“This seemed really far-fetched to me since I was confident that animal protein was necessary to build muscle, sustain energy levels, and recover from injury. So I flew to Austria to meet the researchers who made this discovery and left convinced that the gladiators — known at the time as Hordearii, or “the Barley Men” — really did train and compete on a plant-based diet.

“This shocking discovery launched me on a five-year quest for the Truth in Nutrition, modeled after Bruce Lee’s Truth in Combat philosophy: “Research your own experience, absorb what is useful, reject what is useless, add what is specifically your own.”

“Beginning with this mindset, I put every preconception I had about nutrition to the test, traveling to four continents to meet with dozens of the world’s strongest, fastest, and toughest athletes, as well as leading experts on athletics, nutrition, and anthropology.

“What I discovered was so revolutionary, with such profound implications for human performance and health — and even the future of the planet itself — that I had to share it with the world.”
