Thor Bjornsson Diet: What 'The Mountain' Eats for His Strongman Training

The 'Game of Thrones' actor ate his nickname's worth of protein each day ahead of the 2016 World's Strongest Man competition.

If you really are what you eat, then Hafthór Júlíus Björnsson has earned his nickname as "The Mountain."

The towering Icelandic strongman, who inherited his nickname from the character he played on Game of Thrones, Gregor "The Mountain" Clegane, took to Facebook last week to share his titanic nutrition plan. At 6'9" and nearly 400lbs., Björnsson needs a helluva lot more fuel than the average dude—and that's especially true as he trains for The World's Strongest Man competition. What kind of training? GLAD YOU ASKED:

Naturally, since we love a good nutrition plan (especially one so rich in clean carbs and lean proteins), we decided to drill a little deeper into Björnsson's impressive grocery haul and figure out exactly how many macros—meaning protein, fat, and carbs—this guy needs to eat every day to pull tractor-trailers down the road.

We did have to make a few assumptions:
 - 1: We interpreted a Mountain-sized "handful" as 1 dry cup. (That's about two handfuls for the average man.)
 - 2: In cases where Björnsson chooses between two options (protein OR eggs, for example) we averaged the nutrient profile of both options.
 - 3: All nutrition facts are sourced from the U.S. Department of Agriculture's official National Nutrient Database. Björnsson isn't specific about all his foods, so we made our best guesses and noted the variety we chose.

If that seems like a lot to read, imagine eating all that. (For the record: Björnsson recommends you don't try this.) He puts away nearly 6 kilograms of food—about 13 pounds—every day, including nearly a kilogram of protein. Measuring roughly, his macro balance is about 2:1:2 protein to fat to carbs, although he prioritizes protein and gets slightly more healthy fats than that ratio would imply.

It's also worth mentioning that he does eat plenty of nutrient-rich greens and fruits, which aren't reflected in his macro total but do provide essential nutrients, fiber, and a little taste to his otherwise bland diet.

Bottom line: The guy eats a lot. "I feel for any toilet you come across," one insightful commenter wrote on his post.
