The keen hunter announced on Instagram that he would only eat 'meat and eggs' for the entirety of January as part of 'World Carnivore Month'.
Speaking to former UFC Light Heavyweight Champion Rashad Evans on a recent podcast, Rogan said: "I definitely think [diet] changes the mind because this all-meat diet that I've been on... it makes you more aggressive."
"I have to work out extra to keep the demons at bay... If you think about it, if your body thinks 'okay I have to eat animals all the time because all this mother f****r eats is animals' - if your body thinks that - it's going to sort of take on the characteristics of something that's a predator...
"Your body is gonna think 'I'm more aggressive, oh I have to chase s**t down and kill it'."
Rogan also spoke out about how his 'strict carnivore' diet, which has been branded 'disappointing and irresponsible', gave him powerful diarrhea.
11 days into the diet, Rogan admitted he feared it was 'just a matter of time before he soiled himself in an Instagram post of his 'late night dinner of liver and bacon'.
