REVEALED: This is the diet that transformed Hafthor Bjornsson into The Mountain

There's an old adage 'eat big to train big'.

It turns out they're not sh*tting us. This was the exactly what Hafthor Julius Bjornsson did to transform his body from scrawny basketballer to 28-stone monster. The 26-year-old, who plays The Mountain in Game of Thrones and trained with Conor McGregor before his fight with Jose Aldo, is now one of the strongest men on the planet with a 450kg raw deadlift and two Europe's Strongest Man titles to his name. But the Icelander's diet and ridiculous eating plan played a big hand in forging his giant physique. This video shows what Bjornsson was like before he started smashing the weights and devouring every potato and chicken fillet in sight. https://youtu.be/4BHifeAeBk4 But in an interview with GQ magazine he revealed exactly what he has been eating to make him absolutely massive. "The biggest changes were that I didn't do much cardio anymore, and I put more food into my diet," he told the magazine. "It's just like constantly work for me: I have to eat every two hours to maintain my body mass. It is not easy. When I'm filming, I always have to have breaks to eat." That means eating between six and eight meals a day. "I eat a lot of sweet potatoes, a lot of meat, fish, chicken, good fats like cocoa butter, almonds. I love greens, like spinach, avocado, broccoli. "I eat very healthy overall — but because of my weight, I need fast carbs, easy carbs. So maybe before a training session or after a training session, I eat what I want."
