Trail Food Planning: Calories, Grams per Day and Sample Meal Plans

How much food per day do you need on the trail?

Your daily energy need is your basal metabolic rate (what your body burns at rest) multiplied by an activity factor, plus extra for cold. Our planner uses the Mifflin-St Jeor formula with factors of 1.55 for a camp day, 1.9 for 4–6 hours of hiking and 2.3 for hard days of 8 hours or more. For cold, it adds 1.5 % for every degree the night low falls below 10 °C, up to a maximum of 40 %.

That sounds technical, but the result is intuitive: a lighter, smaller person on a relaxed camp day may need around 2,000 kcal; a larger person hauling a pack uphill in frost can need well over 4,000 kcal. The table shows typical ranges.

How many grams of food per day? Energy density explained

Weight is what you actually carry, so the key figure is energy density: kilocalories per gram of food as packed. Fresh food is mostly water – an apple has around 0.5 kcal/g, bread about 2.5 kcal/g. Dry staples such as oats, pasta and couscous sit around 3.5–3.8 kcal/g, nuts and chocolate at 5–6 kcal/g, and oil tops the scale at almost 9 kcal/g.

Our planner uses three styles: fresh and heavy at 2.5 kcal/g, standard trail at 4.0 kcal/g and ultralight at 5.0 kcal/g. For a 3,000 kcal day that means about 1,200 g, 750 g or 600 g of food.

A practical target for trips of three days or more is 100 kcal or more per 25 g – that is 4 kcal/g. You do not need to hit it with every item; mix a few very dense foods (nuts, oil, chocolate) with bulky but satisfying staples. Weigh each day's bag at home: if it is over about 900 g for an average adult, look for water-heavy items to swap.

Carbs, fat and protein: the right mix for the trail

Carbohydrates are your quick fuel for climbing and cold mornings, fat is the densest energy store (9 kcal/g against 4 kcal/g for carbs and protein) and protein repairs muscles. The planner uses a simple split: 15 % protein, 35 % fat and the rest carbohydrates. When the nights drop below 0 °C, fat goes up to 42 %, because fatty food is compact and digests slowly, releasing heat through the night.

Do not overthink it on short trips – the split matters more on long ones. Two easy rules: add a spoonful of olive oil to every dinner, and eat a fatty snack such as cheese or nuts before sleeping on cold nights. Pair it with a warm sleep system and you sleep noticeably warmer.

The best trail foods by meal

Good trail food is energy-dense, keeps without a fridge, cooks quickly or not at all, and is something you actually like. Food you do not want to eat after a hard day is dead weight. Always test new foods at home.

For bread baked fresh at camp from a light dry premix, see our bannock bread recipe. For evening meals over the fire, our bushcraft recipes and campfire cooking guide (with foil packets for no-wash dinners) have ideas that start from these staples; at a base camp, a Dutch oven turns the same dry staples into bread and stews.

Vegetarian, vegan and gluten-free trail food

Special diets work well on the trail – the only real challenge is getting enough protein and energy without fresh food. Plan the day in the same grams-and-kilocalories way, then check that protein reaches roughly the 15 % the planner assumes.

• Vegetarian: cheese, milk powder, eggs on day one, lentils and nuts cover protein easily. Swap salami for extra cheese or a nut butter wrap at lunch.
• Vegan: use plant milk powder or soy protein in porridge, TVP or red lentils in dinners, and nut butters, seeds and dark chocolate for fat. A spoonful of oil in every dinner closes the energy gap left by missing cheese.
• Gluten-free: rice noodles, instant rice, polenta, quinoa flakes, potato flakes and certified gluten-free oats replace couscous, pasta and wheat tortillas. Corn tortillas or rice cakes work at lunch. Check sauce mixes and bars – many contain wheat.

For group trips, ask about diets and allergies before shopping, pack special portions separately and label them clearly. A gluten-free fire bread that works in the pan is described in our bannock guide.

Sample meal plans for 1, 3 and 5 days

Most trips are built from one "standard day" that you repeat with small variations. Here is a standard day of roughly 3,200 kcal in about 750 g – energy density around 4.3 kcal/g – which suits an average adult hiking 4–6 hours in mild to cool weather. Scale portions up or down to your own number from the calorie planner.

1 day / 1 night: fresh and simple

On an overnighter weight hardly matters, so eat well: sandwiches or rolls for lunch, a sausage or something on a stick over the fire, bannock or twist bread, fresh fruit, a proper breakfast. Plan about 1–1.2 kg of food per person, mostly fresh.

3 days: fresh start, dry finish

Day one uses fresh food (sandwiches, cheese, vegetables for dinner), days two and three switch to the standard dry day. Expect around 2.5–3 kg of food per person, plus a few extra snacks.

5 days: dry, dense and counted

Only the first lunch is fresh; everything else follows the standard day with rotating dinners (couscous, noodles, lentil stew, freeze-dried meals) so you do not get bored. Add one spare day as a reserve. That is roughly 3.8–4.5 kg of food per person – the heaviest single item in many packs, so this is where energy density pays off.

Dehydrating your own trail meals

Drying your own food at home gives you tastier, cheaper and lighter meals than many shop-bought options, and you know exactly what is in them. A food dehydrator is easiest; a fan oven on its lowest setting with the door slightly open also works, just less efficiently.

Making it keep

Fat is what spoils home-dried food: it turns rancid within weeks. Use lean meat, blot away fat and add oil only at camp. Let the dried food cool completely, then pack it airtight in portion bags. As a rough guide, home-dried vegetables and fruit keep for months in a cool, dark place, while dried meat dishes are best used within a few weeks – or kept in the freezer until the trip. Anything that smells off, feels soft or shows mould goes in the bin.

Rehydrating at camp

Home-dried meals need a bit more time than commercial freeze-dried ones: add boiling water to just cover the food, stir, and let it stand 10–15 minutes in an insulated cozy – or soak it in cold water for an hour before you heat it, which saves fuel. Write the water amount on the bag when you pack it.

Repackaging trail food into day bags

Shop packaging is bulky, heavy and produces rubbish you have to carry out. Repacking takes an evening and pays back every day of the trip: you know exactly what you have, you cannot accidentally eat Thursday's dinner on Tuesday, and the food bag fits your pack better.

Cook or no-cook? Hot meals versus cold soaking

Carrying a camp stove costs weight and fuel; going without costs comfort. For most trips a middle way works: a hot breakfast drink and a hot dinner, cold food during the day. On short summer trips some hikers go completely stoveless and "cold soak" – leaving couscous, oats or instant noodles to soften in cold water in a sealed jar for 30–60 minutes.

Water and fuel for cooking

Food planning is also water planning. Dry food saves weight only because you add the water later – so you need a water source at camp or have to carry it. Our water calculator counts 0.4 L of cooking water per person and day for ready-to-eat food, 0.8 L for mixed and 1.2 L for fully cooked dry meals, on top of drinking water.

How much fuel for trail cooking?

Our boiling point and fuel calculator models a typical canister stove: roughly 15–20 g of gas per litre in calm air with a lid and windscreen, and more than 30 g per litre in strong wind. For boiling 1–1.5 L per person and day, plan about 20–30 g of gas per person per day in mild, slightly breezy conditions. A 100 g canister therefore lasts one person roughly 3–4 days, a 230 g canister about a week. Simmering pasta or melting snow needs much more – melting snow can double or triple fuel use; see water from snow.

Water from streams and lakes must be made safe before you drink it or use it for cold soaking. Boiling does that on the way; otherwise use a filter or chemical treatment – see filtering water, water purification methods and boiling water. Collapsible water containers let you carry the evening's cooking water from the last source to camp. The right pot size and material are covered in camp cookware.

Eating on the move: snacks, salt, heat and appetite

On hiking days, lunch is less a meal than a string of snacks. A steady intake keeps energy even and avoids the slump that comes from walking on empty for hours.

• Snack rhythm: roughly every 60–90 minutes, 200–300 kcal – a handful of trail mix, a bar, a piece of cheese. That is how the standard day above fits about 1,200 kcal into snacks. Planning breaks with the hiking time calculator or the pace calculator makes the rhythm easy to stick to.
• Hot weather: appetite often drops while sweat losses rise. Salty foods such as crackers, nuts, soup powder or salami help replace salt; chocolate melts, so switch to hard sweets or dried fruit. Drink regularly – the water calculator estimates how much.
• Cold weather: keep the day's snacks in a jacket pocket so they stay chewable, and eat something fatty before bed. Hot drinks count as fuel for morale, too.
• Loss of appetite: common on the first day, at altitude and when exhausted. Small, familiar, tasty portions work better than large meals; liquid calories such as hot chocolate or soup go down easily.

Resupply on longer trips

Beyond five to seven days, food weight becomes hard to carry, so most people resupply: buying in villages along the route, sending parcels ahead to accommodation or post offices, or leaving a cache where that is allowed. Check opening hours and routes before you rely on a shop; plan resupply points on the map using map and compass navigation. Carry enough to reach the next point plus one reserve day, and plan campsites near reliable water – see finding water.

Food safety on the trail

Without a fridge, the risk is not dry food but moist, protein-rich and cooked food that sits warm. A few habits prevent almost all problems.

Planning for groups, children and winter

Groups: share dinners in one big pot to save fuel and weight, but give everyone their own breakfast, lunch and snacks – people eat at different times and tastes differ. Split shared food evenly between packs.

Children: the calorie planner is designed for teens and adults (from 14). Younger children eat less in total but need frequent small snacks and familiar food; pack generously and bring favourites. More tips in bushcraft with kids.

Winter: expect up to 40 % more calories, more fat, and more fuel for melting snow and hot drinks. Chocolate and cheese go rock-hard in frost – keep the day's snacks in a jacket pocket. Our winter camping guide covers the rest.
