From Thor to thin! Chris Hemsworth reveals he went on a strict 500 calorie a day diet to slim down for epic action flick In The Heart Of The Sea

He's known for his Herculean force and demi-God status in flicks such as Thor and The Avengers. 

But Chris Hemsworth's steel resolve was put to the test in a different way for his latest role in action flick In The Heart Of The Sea.  

The Australian heartthrob was restricted to a miserly 500 calories a day diet while filming the Ron Howard epic, which sees him take on an 85ft vengeful whale with a single spear.

'We have to shoot the really skinny stuff where we drop down to 5,6, 700 calories a day, a good three or four weeks and it's going to be pretty uncomfortable, but we'll be together in our misery,' the 31-year-old told Entertainment Tonight.

The average amount of calories recommended for a man per day depends on his size and activity levels, but it's somewhere between 2000-3000.

People's Sexiest Man Alive 2015 said there was only one thing on his mind during filming.

'All the bad stuff pizzas, hamburgers, chocolate, ice cream... anything that is not on the menu you have an absolute obsession with,' he reveals in the two minute interview.

In December Rush director and Academy Award winner Howard shared a snap of the blonde haired heartthrob on set, revealing his much maligned frame.

Far from the thundering muscular prowess of Thor the athletic actor looked positively waif-like revealing his slimmed down frame in a blue vest and shirt; the weight fallen from his face.

In November Hemsworth spoke of his sailing fodder on Jimmy Kimmel Live

Far from the Australian diet of barbecues he was raised on the Byron Bay based star revealed, 'It ends up being a couple of small salads and a couple small small pieces of protein.

'And that's kind of it, and you go to bed hungry. And then you have a fasting period of 15 hours and then you have little meals through the day.' 

While he might not have been packing on the blubber for the high concept blockbuster, he was certainly burning calories during filming.

Slated for release in December a look at the trailer sees Chris thrust into a battle of life or death on the open seas as he fights to bring the great whale down. 

Based on Nathaniel Philbrick's best-selling novel about the true story of the whaling ship Essex that was assaulted by a gargantuan whale in 1820, Hemsworth is majestic as first mate Owen Chase who refuses to acknowledge defeat. 

Charting the true story of the maritime tale that later became the inspiration for Melville's classic novel Moby Dick, the story descends into a tale of survival as the men are left shipwrecked and stranded for 90 days, thousands of miles from home in South America.

Battling the elements and long days and nights lost at sea, the Thor actor will not give into his fear. 

Hewsmorth is joined on board by Meryl Streep's son-in-law Benjamin Walker who plays Captain George Pollard Jr., Batman's Cillian Murphy as second mate Matthew Joy and Impossible actor Tom Holland as cabin boy Thomas Nickerson.

While Braveheart's Brendan Gleeson and Bond star Ben Whishaw also have credits.
