In the cold, your body craves calories in any form, burning them at a faster rate to maintain core body temperature.
Cookies, crackers, nuts, dried fruit, plain chocolate bars, and jerky are all options. I like high-calorie bars because you only have to buy them once and your food preparation is done.
Snickers bars and candy bars are delicious, but if you eat one that has been sitting in sub-zero temperatures for even a few hours, you’ll chip a tooth on the caramel. Consider adding powdered hot chocolate or another warm drink with a lot of calories if you can heat water over a makeshift stove or fire.
