You can easily burn 4,000 calories a day or more on a cold-weather adventure, which makes it crucial to consume sufficient high-energy food for body heat and go-power.
- Carbohydrates, especially simple sugars, provide the fastest energy and should be your primary source of daytime calories.
- Energy bars and candy bars turn into rock-hard bricks in the cold. Keep them warm in a pocket inside your layers or your teeth and jaw muscles will suffer.
- Easier eating alternatives include fig bars, crackers, and hard pretzels, all of which pack significant (75 to 125) calories per ounce.
- Break up chocolate into little pieces that quickly melt in the mouth. A Thermos of hot chocolate provides quick energy and a delicious way to hydrate. If you’re camping in the cold, load up on fat-rich foods for dinner, which provide sustained energy for nighttime warmth.
