Ultralight Backpacking Food: A Complete List by Calories/Oz
Ultralight backpacking food list ranked by calories per ounce, with protein, how much food weight per day to carry and a sample 1.5 lb day of trail food.
Ultralight backpacking food is food with the most calories per ounce and the least water: olive oil, nuts, nut butters, chocolate, coconut, cheese, and dried staples like instant rice, couscous and oats boosted with fat. Many ultralight hikers aim for an average of about 125 to 140 kcal per ounce (4.4 to 4.9 kcal per gram) and carry roughly 1.5 to 2 lb of food per day. The list below ranks common trail foods by calorie density, with protein, so you can build a lighter bag.
Food is often the heaviest consumable in your pack. Drop from an average of 100 to 130 kcal per ounce and a 5-day trip's food gets several pounds lighter for the same calories. Fat is the reason: it has about 9 kcal per gram, against roughly 4 for carbohydrate and protein.

How much food to carry per day
| Daily calories | At 110 kcal/oz | At 125 kcal/oz | At 140 kcal/oz |
|---|---|---|---|
| 2,500 kcal | 1.42 lb (645 g) | 1.25 lb (567 g) | 1.12 lb (506 g) |
| 3,000 kcal | 1.70 lb (773 g) | 1.50 lb (680 g) | 1.34 lb (607 g) |
| 3,500 kcal | 1.99 lb (902 g) | 1.75 lb (794 g) | 1.56 lb (709 g) |
| 4,000 kcal | 2.27 lb (1,031 g) | 2.00 lb (907 g) | 1.79 lb (810 g) |
The formula is simple: daily calories ÷ average kcal per ounce = ounces of food per day. Our backpacking food weight calculator does this for the whole trip, and the hiking calorie estimator gives a personalised daily target.
A sample ultralight day (about 1.6 lb, 3,300 kcal)
| Meal | Food | Weight | Calories (approx.) | Protein (approx.) |
|---|---|---|---|---|
| Breakfast | Instant oats 60 g, whole milk powder 30 g, walnuts 20 g, brown sugar 10 g | 120 g | 560 | 17 g |
| Snack | Peanut butter packet 32 g + tortilla 50 g | 82 g | 340 | 9 g |
| Snack | Trail mix 70 g (peanuts, almonds, chocolate, coconut) | 70 g | 390 | 11 g |
| Lunch | Tortilla 50 g, hard cheese 40 g, salami 40 g | 130 g | 480 | 24 g |
| Snack | Dark chocolate 40 g | 40 g | 240 | 3 g |
| Snack | Protein bar 60 g | 60 g | 230 | 18 g |
| Dinner | Instant mash 70 g, cheese powder 20 g, olive oil 15 ml, tuna pouch 74 g | 179 g | 760 | 28 g |
| Dessert | Hot chocolate 30 g + milk powder 15 g | 45 g | 190 | 5 g |
| Total | 726 g (1.6 lb) | about 3,190 kcal | about 115 g |
That averages around 125 kcal per ounce, with a fair amount of protein. Swapping the tuna pouch for freeze-dried chicken or adding more nuts and oil would push the density higher. Build your own days in the trail meal planner.
Principles of an ultralight food bag
- Add fat to everything. A tablespoon of olive oil in dinner adds about 120 kcal for about 14 g. Nut butter in oats, coconut in trail mix, cheese on tortillas.
- Remove water. Choose dried, freeze-dried or dehydrated foods over fresh, canned or pouched.
- Keep a protein floor. Very fat-heavy bags can be low in protein. Mix in jerky, cheese, milk powder, protein powder, TVP or freeze-dried meat. See high-protein hiking snacks.
- Repackage everything. Boxes, trays and cans weigh more than you think.
- Plan resupplies tightly. Carrying an extra day of food adds 1.5 to 2 lb.
- Don't cut too far. Running out of energy is worse than carrying a few extra ounces. Keep one spare day of snacks on remote routes.
High-density swaps
| Instead of | Swap for | Why |
|---|---|---|
| Bread | Flour tortillas | Denser, doesn't squash |
| Crackers | Corn chips or nuts | More kcal per oz |
| Fresh fruit | Dried mango, dates | No water weight |
| Tinned fish | Foil pouch, or freeze-dried meat | Lighter packaging |
| Skimmed milk powder | Whole milk powder | More calories, better taste |
| Low-fat bars | Nut-based bars | Higher density |
| Gels only | Gels plus chocolate and nuts | Sustained energy |
| Plain ramen | Ramen + peanut butter + oil | Doubles calories |
Packaging and organisation
How you pack food matters almost as much as what you pack. Lay out every day's food at home, weigh it, and bag it by day or by meal. Write the day number and water needed for each dinner on the bag with a marker. Put the next day's snacks in a hip-belt pocket each morning so you eat on the move instead of stopping. Keep oil and nut butter packets in a separate small bag in case one leaks. In bear country, plan around the size of your canister or bag, since dense food also takes up less room.
Ultralight foods for no-cook trips
Going stoveless saves the weight of a stove, pot and fuel. Good stoveless foods include cold-soaked couscous, ramen and instant mash; tortillas with nut butter; cheese and salami; bars; trail mix; and cold-soaked oats with milk powder. See no-cook backpacking meals.
Ultralight doesn't mean unhealthy
Very calorie-dense diets for a week or two of hiking are common and normal for active people. On long trips, include some variety: dried fruit and vegetables, nuts and seeds, whole grains and protein sources, and eat a few fresh meals in town. If you have a medical condition or dietary restrictions, check with a dietitian before planning an extreme menu.

Frequently asked questions
What is the lightest backpacking food?
Foods high in fat and low in water carry the most calories per ounce. Olive oil (about 250 kcal per oz), macadamia nuts, pecans, nut butters, coconut, chocolate and peanuts all exceed about 150 kcal per oz, compared with roughly 100 to 110 for most dried carbohydrates.
How much food weight per day for ultralight backpacking?
Many ultralight hikers carry around 1.5 to 2 lb (680 to 900 g) of food per day, at an average of about 125 to 140 kcal per ounce. That gives roughly 3,000 to 4,500 kcal. Your needs depend on your size, pace, terrain and climate.
What is a good calorie per ounce target for backpacking food?
A common target is 100 kcal per ounce as a minimum and 120 to 130 or more as a good average across the whole food bag. Mixing very fatty foods with dried carbohydrates is how most hikers hit it.
Is fat or carbohydrate better for long hikes?
You need both. Fat is the most weight-efficient fuel at about 9 kcal per gram, while carbohydrate is the body's preferred fuel for harder efforts and climbs. Most hiking food plans balance the two, with protein for recovery.
How can I cut weight from my food bag?
Repackage into zip bags, swap low-density foods (fresh fruit, crackers, tins) for dense ones (nuts, nut butter, olive oil, chocolate), add oil to dinners, carry powders instead of liquids, and plan resupplies so you don't carry extra days.
