James Cameron credits his vegan diet with providing him with an "amazing surge of energy" that has lasted for years. He initially resisted the idea of going plant-based due to societal associations between meat and masculinity, but after learning about the health benefits, he quickly changed his perspective. Cameron also challenges the notion that meat is essential for masculinity and athletic performance through his work as an executive producer on The Game Changers, which highlights elite athletes thriving on plant-based diets.

Cameron and his wife, Suzy Amis Cameron, have been active in advancing the plant-based movement, with Amis Cameron founding the One Meal a Day for the Planet initiative. Cameron even proposed a new term for veganism in 2022, suggesting "futurevore" to reflect their belief that they are eating the way people will eat in the future. The couple continues to advocate for plant-based eating for health and environmental reasons, with Cameron experiencing sustained energy and healthfulness on his vegan diet.
