Backpacking long distances in mountainous terrain can burn up to 5,000 calories per day. Because fat provides the highest source of calories by weight, hikers need to consume a higher amount of fat to account for lost calories. Besides providing energy, fats are vital for insulating your body, supporting immunity and brain health. They are also necessary for vitamin absorption, acting as carriers for fat-soluble vitamins (A, D, E, and K).
There are many different types of fats, but only a few are essential. The essential fats are those that your body cannot create internally and must be consumed through food. These essential fats include omega-6 fatty acid (linoleic acid), and omega-3 fatty acid (linolenic acid), and are highest in nuts, seeds, and fish. See also a chart of the breakdown of fats (omega-3 and omega-6) found in nuts and seeds.
If you are planning food for a long-distance hike, we suggest adding fat (oil, nuts/seeds) to all of your trail meals. Focus predominately on healthier plant-based fats (unsaturated) such as olive oil to maintain cardiovascular health. Although tropical oils (palm, coconut, and cocoa butter) are plant-based fats, they are high in saturated fat. There is controversy regarding whether or not saturated fats from plants have the same harmful effect on the heart as the saturated fat found in animal products. We advise you to use these in moderation. Here is a list of fats to use to increase your daily calorie requirements.
