How-To

How Much Food to Bring Backpacking

Pounds per day, calories per day, and how to stop carrying three days of food for one night.

Written by William • Updated August 2026 • 6 min read

Food is usually the second heaviest thing in a pack after water, and it is where beginners most consistently overpack. Planning by weight and calories rather than by meals produces a food bag that is both lighter and more likely to be eaten.

  1. 1

    Use pounds per day as the planning unit

    Roughly 1.5 pounds per person per day for short easy trips, 2 pounds for typical backpacking, and up to 2.5 for long strenuous days or cold weather. Weigh your food bag before you leave and compare it against days multiplied by that figure — the discrepancy is usually large.

  2. 2

    Cross-check against calories

    Most backpackers need somewhere between 2,500 and 4,500 calories a day depending on effort, body size, and temperature. Cold weather increases the requirement noticeably because your body spends energy staying warm.

  3. 3

    Chase calorie density, not just calories

    The relevant number is calories per ounce. Around 100-125 calories per ounce is efficient; below about 80 you are carrying water and packaging. Nuts, oils, nut butters, cheese, and chocolate sit at the high end; fresh fruit and canned anything sit at the bottom.

  4. 4

    Plan by days, then assign meals

    Count the days, multiply by your daily weight target, then fill that budget with meals rather than the reverse. Packing meal by meal is how people end up with nine dinners for a three-night trip.

  5. 5

    Carry one spare day of food, not three

    A single extra day's food is sensible insurance for a delay. Beyond that you are carrying weight you will almost certainly walk back out with. Make the spare day calorie-dense and shelf-stable so it survives repeated trips.

  6. 6

    Account for appetite changing

    Appetite is often suppressed on day one and increases sharply from day three onward on longer trips. Front-load palatable food and put the calorie-dense items later, when you will actually want them.

Frequently Asked Questions

How many calories per ounce should I aim for?
Around 100-125 is efficient. Below 80 you are largely carrying water and packaging, which is why fresh and canned food rarely makes sense on the trail.
Do freeze-dried meals have enough calories?
Often less than the packet implies, because many two-serving pouches are one realistic backpacking portion. Read the calories per pouch rather than per serving.
What if I run out?
Most people can walk out on very little for a day, and it is unpleasant and affects judgement. Carry one spare day's food and know your bail-out options rather than relying on toughing it out.
