Energy density (food)
Overview
Energy density, in the context of hiking food, refers to how many calories are contained per unit weight or volume of food. It is a key factor in planning efficient resupplies for long-distance hiking.
Key points
- Often expressed as calories per 100 grams or per ounce.
- Higher energy density allows more calories to be carried for the same weight.
- Common trail foods balance energy density with palatability and nutrition.
- Very high energy density does not automatically mean a complete diet.
- Individual preferences and dietary needs shape food choices.
Details
Long-distance hikers pay attention to energy density because carrying food for multiple days is a significant portion of pack weight. Foods with higher energy density provide more calories for the same mass, which can help reduce overall load between resupplies. Examples include items rich in fats and carbohydrates, such as nut butters, certain trail mixes, and some dehydrated meals.
However, energy density is only one consideration. Hikers also need foods that are practical to prepare and eat, that sit well during exertion, and that provide a mix of macronutrients and micronutrients appropriate to their needs. Very high energy density items can be useful but may not be satisfying or nutritionally balanced if they are the only food source.
Resupply strategies often combine a variety of foods with different textures and flavors, aiming to maintain interest over many days. Over time, hikers refine their choices based on how they feel, what they crave, and how their bodies respond.
Energy density calculations are a planning tool rather than a strict rule, helping hikers estimate how much food to carry in relation to expected daily expenditure and personal appetite.
