Chris Hemsworth eats 10 meals and 4,500 calories a day to get Marvel-ready, according to a chef who works with him

• Chris Hemsworth eats up to 4,500 calories a day to prepare for roles, said chef Dan Churchill.
• Staple foods include steak, chicken, broccoli, and banana protein shakes, he told The Daily Mail.

Chris Hemsworth eats as many as 4,500 calories per day to prepare for films like "Thor" and "Extraction," his chef Dan Churchill told The Daily Mail.

The Marvel actor eats up to 10 meals a day made up of 450 calories each to bulk up for his roles, relying on foods like steak, chicken, broccoli, and banana protein shakes, according to Churchill, who puts together recipes for Hemsworth's fitness app Centr.

That's much more than most people need to eat on a daily basis. Men between ages 31 and 59 generally have a daily calorie requirement of 2,200 to 3,000 calories per day, according to recommendations from the USDA's Dietary Guidelines for Americans, while women the same age have a requirement between 1,600 and 2,200.

'"It takes a lot of discipline to adhere to Chris's schedule — he often has to sacrifice taste and flavor to get the job done," Churchill told The Daily Mail.

Hemsworth is no stranger to extreme dieting

Hemsworth eats 300 grams of protein each day when gearing up to make movies like "Thor," Luke Zocchi, Hemsworth's personal trainer, previously told Insider. That's more than double the amount of daily protein recommended by dietitians.

Hemsworth has also gone vegan for some roles, like "Avengers: Endgame," according to Zocchi.

"We wanted to see if he could maintain a certain size, and were surprised by how well it worked," Zocchi said. Hemsworth stayed on the diet for eight weeks, eating extra beans to maintain muscle, but eventually returned to his regular meat consumption habits because he missed steak so much.

Hemsworth has gone to other extremes to prepare for his roles as well. According to Zocchi, the star undergoes a dehydration process before shooting his topless scenes, increasing water intake a week beforehand and then avoiding it altogether in the day and a half before filming.

"This is by no means a healthy thing to do, and I wouldn't recommend that anyone else do this," Zocchi told Insider.
