Should I change my food habits for my winter activities?
Is simply increasing the quantities or choosing food with higher calories enough?
- Caloric intake is certainly the largest factor. Calories are energy.
- If you are on a low fat diet normally and a very fit individual, you'll likely need to increase your fat intake. However the primary concern is that you are getting fats, so if you are already, you should be fine.
- Drink more water! It's very counter intuitive, but you dehydrate faster in the cold.
One other difference - in the winter, your food and water can freeze during the day. Make sure that your lunch (or anything else you'd eat without cooking) is something that you can actually chew when its frozen. Also, camelback-style water bladders can be a little more difficult to use, as the water in the tube can freeze up.
