What to Eat Before, During, and After Your Trek
Nutrition is the most underrated part of trek preparation. Get it right and you'll have the energy to push through tough days. Get it wrong and you'll be running on empty by day three.
Most trekkers spend months training their bodies and minutes thinking about nutrition. That's a mistake. What you eat in the weeks before your trek, on the trail, and during recovery has a massive impact on your performance, energy levels, and how quickly you bounce back.
Here's a practical nutrition guide built specifically for Himalayan trekkers.
Pre-Trek: Building Your Fuel Stores
In the 4–6 weeks before your trek, focus on:
Complex carbohydrates: Brown rice, oats, sweet potato, and whole grain bread are your primary energy source. Don't fear carbs — on a multi-day trek, you'll burn through them rapidly.
Lean protein: Chicken, fish, eggs, legumes, and dairy help repair muscle tissue after hard training sessions and build the strength you'll need on the trail.
Healthy fats: Avocado, nuts, olive oil, and fatty fish support sustained energy and reduce inflammation.
Iron-rich foods: Altitude reduces your blood's oxygen-carrying capacity. Eating iron-rich foods (spinach, lentils, red meat) in the weeks before your trek helps your body produce more red blood cells.
On the Trail: Eating for Energy
At altitude, your appetite often decreases — but your caloric needs increase. You may be burning 3,000–4,500 calories per day on a demanding trek. Force yourself to eat even when you don't feel hungry.
Breakfast: A substantial, carbohydrate-rich meal before you start walking. Porridge, eggs, toast, and local dal are all excellent choices at teahouses.
On the move: Snack every 60–90 minutes. Trail mix, energy bars, dried fruit, and nuts are lightweight and calorie-dense. Avoid anything that requires cooking.
Lunch: A warm meal mid-day if possible. Dal bhat (lentils and rice) is the trekker's staple for good reason — it's nutritious, filling, and available everywhere.
Hydration: Drink 3–4 litres of water per day at altitude. Add electrolyte tablets to prevent hyponatremia (low sodium from over-hydration).
Post-Trek Recovery
After a multi-day trek, your muscles are depleted and your immune system is under stress. Prioritise:
- Protein within 30 minutes of finishing: A protein shake, eggs, or Greek yoghurt helps kick-start muscle repair
- Anti-inflammatory foods: Turmeric, ginger, berries, and leafy greens reduce post-trek soreness
- Sleep: Your body does most of its repair work while you sleep. Prioritise 8–9 hours in the days after your trek
Nutrition isn't glamorous, but it's one of the most powerful tools in your trekking toolkit. Get it right and you'll feel the difference on every climb.
