One of the most common mistakes new hikers make is either overpacking food (and suffering under the weight) or underpacking (and bonking hard on day two). Getting your food quantities right is both a science and a skill — and it gets easier with experience. Here's a practical breakdown for 2, 3, and 5-day hikes.
Start With Calories, Not Weight
Before calculating quantities, understand your baseline. The average hiker burns:
- 2,000–2,500 calories/day on flat to moderate terrain
- 2,500–3,500 calories/day on technical or mountainous terrain
- 3,500–4,500+ calories/day in cold conditions or on very high-output days
Your food plan should match your expected output — not just your appetite at home.
The Golden Rule: 500–700g of Food Per Day
As a practical rule of thumb, plan for 500–700g of dry food per person per day. This accounts for a mix of meals, snacks, and drinks across the day and typically delivers 2,000–2,500 calories.
For higher-output days or cold-weather hiking, push toward the upper end or add calorie-dense supplements like nut butter sachets or energy bars.
Food Quantities by Trip Length
2-Day Hike (1 night on trail)
| Meal | Quantity |
|---|---|
| Breakfasts | 1 (Day 2 only) |
| Lunches | 2 |
| Dinners | 1 |
| Snacks | 4–6 portions |
| Total food weight | ~800g–1.2kg per person |
Tips: Eat a solid meal before you set off on Day 1 — no need to carry breakfast for the first morning. Keep it simple: wraps, biltong, nut butter, and one freeze-dried dinner covers most of this comfortably.
3-Day Hike (2 nights on trail)
| Meal | Quantity |
|---|---|
| Breakfasts | 2 |
| Lunches | 3 |
| Dinners | 2 |
| Snacks | 6–9 portions |
| Total food weight | ~1.5kg–2kg per person |
Tips: This is where freeze-dried meals really earn their place — two hot dinners without the weight of fresh ingredients. Plan your snacks carefully: aim for a mix of fast-release (dried fruit, energy chews) and slow-release (nuts, biltong) options. Carry a small emergency ration — an extra energy bar or two adds minimal weight but significant peace of mind.
5-Day Hike (4 nights on trail)
| Meal | Quantity |
|---|---|
| Breakfasts | 4 |
| Lunches | 5 |
| Dinners | 4 |
| Snacks | 10–15 portions |
| Total food weight | ~2.5kg–3.5kg per person |
Tips: At 5 days, food weight becomes a serious pack management consideration. Prioritise calorie-dense, low-moisture options throughout. Freeze-dried meals for every dinner (and ideally breakfast) will save significant weight versus alternatives. Consider resupply points if the route allows. Appetite often drops on longer trips due to fatigue — choose meals you genuinely enjoy eating.
Sample Daily Food Plan (Per Person)
| Time | Food | Approx. Calories |
|---|---|---|
| Pre-hike | Coffee/tea + energy bar | 200 |
| Breakfast | Freeze-dried breakfast or instant oats | 450–500 |
| Mid-morning snack | Handful of nuts + dried fruit | 200 |
| Lunch | Wrap + nut butter + biltong | 500 |
| Afternoon snack | Energy bar or droëwors | 200–250 |
| Dinner | Freeze-dried meal | 550–650 |
| Evening | Hot drink + small treat | 100–150 |
| Total | ~2,200–2,750 cal |
Factors That Change Your Food Needs
Increase your food quantities if:
- Temperatures drop below 10°C (your body burns more calories staying warm)
- You're carrying a heavy pack (15kg+)
- The route involves significant elevation gain
- You're a larger or more muscular hiker with higher baseline calorie needs
You may be able to reduce slightly if:
- The terrain is flat and well-maintained
- You're a smaller or lighter hiker
- The trip is in warm conditions with moderate daily distances
Don't Forget Water Weight
Water is the heaviest thing in your pack — but you can't carry enough for a multi-day trip. Plan your route around water sources and carry a reliable filter or purification tablets. This also affects your meal choices: freeze-dried and dehydrated meals require water to rehydrate, so factor this into your water planning.
Quick Reference Summary
| Trip Length | Food Weight (per person) | Freeze-Dried Meals Needed |
|---|---|---|
| 2 days | 800g – 1.2kg | 1 dinner |
| 3 days | 1.5kg – 2kg | 2 dinners + 1–2 breakfasts |
| 5 days | 2.5kg – 3.5kg | 4 dinners + 3–4 breakfasts |
The Bottom Line
Getting your food quantities right comes down to knowing your daily calorie needs, choosing high calorie-to-weight ratio foods, and planning each meal slot deliberately. For any trip of 2 days or more, freeze-dried meals are the most efficient way to hit your calorie targets without the weight penalty.
Plan well, pack smart, and you'll never bonk on the trail again.
