How to Plan Backpacking Food
Proper food planning for backpacking balances three variables: enough calories to fuel your activity, minimal weight to carry, and food you will actually enjoy eating after miles of hiking. The golden rule is 1.5–2.0 lbs of food per day targeting at least 100 calories per ounce.
Calorie Density is King
Every ounce in your pack matters over long miles. Focus on high-calorie-density foods: nuts and seeds (160-180 cal/oz), nut butters (160-180 cal/oz), olive or coconut oil (240 cal/oz), hard cheeses (110-130 cal/oz), dried fruits and coconut (80-100 cal/oz), and freeze-dried meals (100-130 cal/oz). Avoid bulky, water-heavy foods that provide few calories per weight.
Meal Structure on Trail
Most experienced backpackers organize food into 3 main meals plus 3-4 substantial snacks. Breakfast should be quick — oatmeal with nut butter and dried fruit is a classic, providing 500-700 calories in under 10 minutes. Lunch is typically a no-cook spread of crackers, hard cheese, salami, nuts, and bars. Dinner is the main hot meal where freeze-dried or home-dehydrated meals shine.
Resupply Planning
For trips longer than 5-7 days, most hikers use a resupply strategy — mailing food boxes to post offices, outfitters, or stores along the route. This allows fresh food at intervals and reduces the load you carry at any given time. On longer trails like the PCT or AT, resupply every 4-7 days is the norm.
FAQ

Yes, completely free with no signup required.
How many calories do I need per day backpacking?
Most backpackers need 2,500–4,500 calories per day depending on body weight, terrain difficulty, pack weight, and temperature. A 160-lb person on moderate terrain typically needs about 3,000 calories/day. Cold weather and steep terrain can push this to 4,000+ calories.
How much does backpacking food weigh per day?
A widely used rule is 1.5–2.0 lbs (680–900 grams) of food per person per day for a calorie density of about 100 calories per ounce. High-calorie-density foods (nuts, olive oil, freeze-dried meals) can get you to 2,500+ calories within 1.5 lbs. Lower-density foods like fresh vegetables weigh much more per calorie.
What is calorie density and why does it matter?
Calorie density is calories per ounce or gram. For backpacking, you want foods above 100 calories per ounce (350 cal/100g). Nuts and nut butters: 160-180 cal/oz. Olive oil: 240 cal/oz. Freeze-dried meals: 100-130 cal/oz. Rice: 100 cal/oz (dry). Fresh vegetables: only 5-15 cal/oz. High density = less weight to carry.
Should I pack more calories for cold weather?
Yes. Cold temperatures significantly increase calorie burn — your body works harder to maintain core temperature. Add 25-50% more calories for trips below 20°F (-7°C). Winter mountaineering can require 5,000-6,000 calories per day for sustained activity in extreme cold.
