Winter trekking and camping has its specific requirements for food, see here examples of what will keep you in good shape!
Difference between Summer & Winter Camping:
Basic Difference: Summer camping and winter camping are different ball games for many reasons, but what makes their difference pronounced is the food. Winter activities demand more of your body’s energy.
Energy Requirement: Compared to an average of 420 calories per hour for summer backpacking, the winter campers need an ideal size of 540 calories per hour. The extra calories should come in the form of Carbohydrates, which are digested quickly and provide sustained energy.
Composition: The overall composition of a winter campers’ calories should come in the proportion of 60 to 65%5 from carbohydrates, 20 to 25% from proteins and 10 to 15% from fats. Fats provide your body the energy and warmth.
Further in winter the need for high energy foods and for fluids increases. Much of the body’s water is lost through perspiration and breathing dry and cold air. If possible the liquid should be warm to conserve the heat of the body.
Let's see what food experts are taking for winter camping...
Food for short duration winter camping is much easier to prepare than several days of snow camping. Three things have to be balanced while deciding about food items to carry for a longer duration camp, namely fuel weight, food weight and calories delivered. The preference should be for such food that needs little fuel to carry. Rice or pancakes, for instance may guzzle your scanty fuel whereas dehydrated soups or stews are excellent from this angle.
Light ingredients like potato flakes or instant rice, dehydrated macaroni, which are expanders, may be added to soups and dehydrated meals. Dehydrated food stuff is ideal as they require less fuel and less handling for cooking. Fatty foods like peanut butter, margarine, nuts and cheese replenish energy supply to the body.
Fresh fruits are not a good option as freezing temperature destroys the fresh fruits.
All day’s smorgasbord should add up to 2 pounds of food per day providing 5000 calories. On a party day, when other campers visit, campers may splurge with pre-cooked steak or chicken.
