Strongman Eddie Hall has revealed he's managed to shed more than six stone in just two months as he prepares to fight Hafþór Björnsson - and that's despite consuming 7,000 calories a day, believe it or not.
The former World's Strongest Man has been going through a tough training schedule in preparation for his Las Vegas boxing match next year, which will see him go head-to-head with the Game of Thrones star.
Hall, whose nickname is 'The Beast', has been keeping a close eye on his nutrition to ensure he's in the best shape for the big day. But while you'd probably assume that would mean he's been eating nothing but rice cakes, he's actually been chowing down on 7,000 calories a day - almost three times the recommended intake for an adult male.
His six daily meals include food like chicken, rice, vegetables, chocolate, granola, baked potatoes and coleslaw, along with a few snacks to keep him going.
Hall said: "Because of my size and the intensity of my training programme, I have to eat a lot.
"I currently consume about 7,000 calories a day, containing a variety of protein, carbs and vegetables.
"It's not only time consuming to eat so much, it also takes a lot of forward planning, consistency, and effort."
He's also been using a personalised supplement provided by Birmingham-based food tech start-up Nourished, which provides him with up to 21 targeted vitamins and nutrients in the shape of 3D-printed vegan 'gummies'.
But it's not just about what Hall's eating, as he's also been working hard with gruelling daily cardio, swimming and High Intensity Interval Training (HIIT) sessions.
And, of course, he's also been learning the art of boxing, which he said is a 'whole new ballgame' for him, which 'requires a different kind of fitness and endurance to Strongman'.
The clash with Björnsson, who is known for playing Ser Gregor 'The Mountain' Clegane in Game of Thrones, is scheduled for next September.
Hall, who also uses cryo chambers as part of his intense regime, continued: "It's important I keep up my energy levels and focus and that my muscles recover quickly, which supplements can really help with.
"Due to my size and the level at which I'm training, I also need to take more vitamins and supplements than the average person - so it was crucial I found a more effective and convenient solution than popping loads of pills each day."
