How many calories do I need per day camping?

Base camp with light activity: 2,000-2,500 kcal. Moderate hiking: 3,000-3,500 kcal. Strenuous mountaineering: 4,000-5,000+ kcal. Cold weather and altitude significantly increase needs.

Why does cold weather increase calorie needs?

The body burns extra calories to maintain core temperature through thermogenesis (shivering and non-shivering). In cold conditions, expect 10-20% higher calorie needs. In extreme cold, this can exceed 30%.

How does altitude affect calorie needs?

Above 2,500m, the body increases metabolic rate to cope with lower oxygen. Appetite often decreases at altitude despite higher energy needs, making calorie-dense foods especially important.

How much food weight should I plan per day?

Using dehydrated and calorie-dense foods, plan for 600-800g per person per day. Fresh food is heavier at 1,000-1,500g per day. Focus on foods with high calories per gram: nuts (6 kcal/g), chocolate (5 kcal/g), dried pasta (3.5 kcal/g).

What macronutrient split is best for hiking?

Approximately 55% carbohydrates for energy, 20% protein for muscle repair, and 25% fat for sustained energy and calorie density. Fat is the most calorie-dense macro at 9 kcal/g, making it ideal for weight-conscious packing.

How We Calculate This

Calorie Estimation

Daily calories are estimated from your Basal Metabolic Rate (BMR) multiplied by an activity factor. Additional adjustments are made for cold weather (thermogenesis) and altitude (increased metabolic demand).

Daily Calories = BMR x Activity Factor x Temperature Adjustment x Altitude Adjustment
