We particularly enjoyed Chris Hemsworth as the 2nd mate in 2015: In Heart the Heart of the Sea

Chris Hemsworth is a Hollywood actor hailing from Australia, where he started in soaps. Since then he has starred in Star Trek and some of the Marvel superhero series, including Thor, where his physique helped to land him those roles. He also starred in 'In The Heart Of The Sea,' and 'Ghost Busters.'

You don't need weights to get fit, but they are necessary if you want to bulk up for any tough guy part in television or movies. Many extras have started from being the strong man in a crowd, especially pirate movies, then progressed to acting. Getting into the right frame of mind, is more than just pumping iron, it is a regime based on good diet, eating patterns and regenerative sleep.

DIET

Chris is renowned for packing on tons of muscle for leading roles like "Thor." He supports his beefy physique by eating lots of meat.

While filming "Avengers: Endgame," the actor decided to experiment with a vegan diet. But he didn't stick with it long term, due to his love of steak, though he managed being plant-based for eight weeks and maintained his muscle mass. 

To stay buff, Hemsworth ate a ton of beans, but has since gone back to his more typical muscle-building diet that includes plenty of steaks. Hemsworth eats about 4,000 calories and 300 grams of protein per day to build muscle 

While training for roles in movies like "Thor," his trainer confirmed that Hemsworth needs to eat a lot of calories to put on muscle, since he has a naturally high metabolism. 

About 30-40% of those calories are in the form of protein, with the remaining calories evenly split between carbs and fat.

The resulting 300 grams of protein Hemsworth eats per day is more than twice the recommended amount for most people. Dietitians recommend around .35 to .6 grams per pound of body weight for the average person, which for someone of Hemsworth's size would be approximately 77 to 132 grams of protein.

For muscle building, the Academy of Nutrition and Dietetics recommends .6 to 1 grams of protein per pound of body weight a day.

Chris maintained muscle as a vegan by eating beans and grains, but the down side is that it made him gassy.

To see if Hemsworth could keep his muscle mass on a vegan diet, the actor "dove in" to plant-based eating for several weeks on the set of "Avengers: Endgame."

Hemsworth relied mainly on quinoa and legumes for protein, and was lucky enough to have a chef that specialized in vegan cooking. Though this brief foray into veganism might have upset some of the other, less gassy, actors.

Apparently, it can be kind of aggressive on the stomach when you first stop eating meat. With perhaps more trips to the bathroom. Steak is one of Hemworth's favorite foods, and makes up a big part of his typical diet

Hemsworth ultimately didn't stick to a vegan diet because of the huge amount of plant-based food he had to eat for his goals. 

His typical routine involved eating six to 10 smaller meals a day, usually involving some form of animal protein like chicken, fish, or his favorite, red meat. 

He loves a filet steak, just by itself, and never gets sick of it. It is said that there is something about that Hemsworth DNA, where they just crave red meat.

The actor's younger brother, Liam, has also previously experimented with veganism, but went back to an omnivorous diet after health complications.
