Take on more calories
Food as we know is of great importance to a crew on a shoot, like Napoleon's army we march on our stomachs and in the Arctic the need to eat becomes even greater.
During winter months your body will burn up around 6000 calories a day just standing still so it is vitally important that there are plenty of snacks to be had whilst filming and also plenty of hot drinks.
Remember however that food once taken out into the cold will, inevitably, be frozen solid after an hour or so, so think carefully about what you take. Most chocolate bars become impossible to eat as do sandwiches. If you are going to be out for the day the best option is to take dried ration packs which can be quickly re-hydrated with hot water.
Most of the time, and especially if you are on an expedition away from settlements the best course of action is to eat what the locals eat, this is generally meat and not much else, but because it is shot to order it is very fresh and tasty, but can get somewhat monotonous.
It does mean however that vegetarians can have big problems, once out of major settlements fresh fruit and veg are almost unheard of. Also food is generally shot and butchered in front of you – eating alfresco is not for the squeamish.
On my last Arctic shoot our vegetarian researcher had to eat raw Whale and Seal meat along with the rest of us as the nearest store was a eight day return dog sled journey away!
