Bear Grylls now eats steak for breakfast, lunch and dinner.
The adventurer and television presenter, 52, best known for Man vs. Wild – broadcast in the UK as Born Survivor with Bear Grylls, as well as Celebrity Bear Hunt and Running Wild with Bear Grylls, said he has abandoned veganism in favour of what he describes as a meat-heavy, carnivore-style diet, saying the change has transformed both his health and that of his family.
