How much weight did Game of Thrones star Hafthor Bjornsson lose?

Hafthor Bjornsson revealed in an Instagram post in May of 2021 that he has lost about 110 pounds.

Bjornsson, who is 6-foot-9, had previously weighed more than 400 pounds.

Last year he set a deadlift world record by lifting 1,104 pounds at a gym in his native Iceland.

“Great way to finish my strongman career,” he previously wrote on social media.

“Now a different journey starts and I’m super excited.

“It’s been a great time in the sport of strongman but I’ve decided that I’m going to take a long break from the sport.

“Maybe I’ll never return but never say never right. I’m still only 31 years old and could come back in few years if my heart wants it! Right now my heart tells me that I need to be healthy for my family and do what’s best for them!”

Bjornsson played Sir Gregor Clegane, “The Mountain,” on the hugely successful HBO series Game of Thrones. He appeared in 17 episodes.
