The basics of hiker food — the concept of calorie density
kcal/g is all
The most important number when choosing food for a long trail is "calorie density"—how many calories are in it per gram. If you want to keep your pack light, get the same calories from lighter foods.
| ingredients | Calorie density | Memo |
|---|---|---|
| olive oil | 9.0 kcal/g | The best. I put it on everything. I refill it into a small bottle. |
| Peanut butter | 5.9 kcal/g | Spread it on a tortilla. It's heavy, but very satisfying. |
| Nuts (mixed) | 5.5–6.5 kcal/g | The mainstay of trail food. Macadamia nuts have the highest density. |
| chocolate | 5.0–5.5 kcal/g | It melts in the desert. It works from Sierra onwards. |
| Instant ramen | 4.0–4.5 kcal/g | Cooking time: 5 minutes. Drinking the soup will also help with hydration. |
| oatmeal | 3.8 kcal/g | Breakfast base. Mix with powdered milk. |
| Couscous | 3.6 kcal/g | It cooks faster than pasta (just add hot water). |
| Dry pasta | 3.5 kcal/g | The main component of dinner. Requires water and fuel. |
| Toreiru Yokan | 3.0 kcal/g | It won't melt at 40℃. It can be eaten with one hand. |
| Dried fruit | 2.5–3.5 kcal/g | A sugar boost. It's heavy, but the calorie density is relatively low. |
| Kaki no Tane (rice cracker seeds) | 4.7 kcal/g | Japan's proudest and strongest energy food. Contains salt, carbohydrates, and is lightweight. Convenient small packets. |
| Jagariko | 5.0 kcal/g | Crush it and add hot water to make mashed potatoes. It can also be used for cold soaks. |
| Instant rice | 3.6 kcal/g | Soak in hot water for 15 minutes, or in cold water for 60 minutes. You can also do a cold soak in a food canister. |
| Freeze-dried miso soup | 3.0–3.5 kcal/g | Perfect for replenishing electrolytes. Lightweight and useful on trails abroad. |
| Curry rice / Curry roux | 4.0–4.5 kcal/g | Instant curry made with instant rice and curry roux. A lifesaver on tiring days. |
High calorie density does not necessarily equal good.
If you ask me if you could walk for five months on just nuts and olive oil, the answer is no. You'd get bored. Your mental health would suffer. It's important to have room for "something you want to eat occasionally, even if it's low in calories." I always included dried fruit (low in calories but sweet) and chips (bulky but provides salt). This is an expense for mental health.
