Hafþór "Thor" Björnsson is a man who has a lot on his plate. In addition to playing Gregor Clegane/The Mountain on the hit HBO drama Game of Thrones, he also competes in strongman competitions across the globe and is the current World's Strongest Man. However, that sort of lifestyle also requires him to have a lot on his actual plate.

"I am eating around 10,000 calories a day, which is a lot," Björnsson said in an interview with Uproxx. "I’m obviously a professional and I am the World’s Strongest Man. This is something that a normal human being would never do. You would never eat that amount of food, because you would get tired, it’s too many calories for you to intake."

Björnsson, who stands 6 foot 9 and typically weighs in at over 400 lbs., spaces his six daily meals out every 2.5-4 hours, which can be difficult while shooting Game of Thrones.

"For example, when I have to shoot that day, I have to basically eat on set," he said. "Just like eat between takes and if I’m shooting for 18 hours, I’m definitely going to rest that day, I don’t want to go to the gym. So, you have to listen to your body as well. Some days you just can’t train."

Game of Thrones will return for its eighth and final season in April 2019. In addition to Hafþór Björnsson's Gregor Clegane, the series also stars Peter Dinklage as Tyrion Lannister, Nikolaj Coster-Waldau as Jaime Lannister, Lena Headey as Cersei Lannister, Emilia Clarke as Daenerys Targaryen and Kit Harington as Jon Snow.
