How Much Food to Pack for Backpacking
Food is often the heaviest consumable in your pack, so packing the right amount — and the right kind — matters. Start from calories: multiply your days on trail by your daily calorie burn, which climbs steeply with terrain and pack weight. Then convert calories to weight using your food's density.
Calories by effort
An easy trail day might burn 2,500 calories; a strenuous one with big climbs and a heavy pack can top 4,500. Underpacking leaves you depleted on day three; overpacking means carrying dead weight. Match calories to the difficulty you actually expect, not your at-home appetite.
Density is the whole game
The difference between a heavy and a light food bag is calories per ounce. Fresh and watery foods are dense in weight but poor in calories; nuts, nut butters, oils, cheese, and dense bars pack 130+ calories per ounce. Experienced backpackers obsess over this number because it directly sets how much weight they carry per day of eating.
