Sometimes you eat oatmeal in a hotel room
Nick Beyeler is an aerialist who plays a Na'vi inhabitant, and looks like he might be related to The Situation from Jersey Shore (he's not). Beyeler, a 41-year-old Swiss who eats a healthy Mediterranean diet, only has 5.7% body fat – to put that in perspective, male marathon runners usually have between 5-11%. Even though the dining hall is open in the mornings for breakfast on performance days, he makes oatmeal in his hotel room and travels with an espresso machine.
While he loves when the catering crew cooks fresh pasta dishes, he still misses high-quality cheese and chocolate from Switzerland on the road, so when his mom visits him, she makes sure to bring some. He's a super-nice guy, so I'm not going to say anything about him being a momma's boy, mostly because his background is in contemporary dance. Oh, and martial arts.
