There’s a moment every long-haul traveller knows well.
You’ve made it through security, survived the departure lounge, and settled into your seat. The cabin crew comes round with the first meal service. You open the foil tray, look at the rubbery chicken or the sad pasta, and think: “This is meant to be food?”
You eat it anyway because you’re hungry. An hour later, you feel worse than before.
Bloated. Sluggish. Drowsy.
This isn’t just bad luck—it’s bad nutrition. And it makes jet lag so much worse than it needs to be.
Why Airplane Food Fails You
Airline meals are designed for mass production and long shelf life, not for keeping you energised. They tend to be:
- High in refined carbs (white rice, pasta, bread) that spike blood sugar
- Low in protein (the tiny portion of chicken doesn’t count)
- Packed with sodium (leaving you bloated and dehydrated)
The result? You crash mid-flight, arrive feeling terrible, and lose a day of your trip to recovery.
How Protein Fixes This
Protein is the smart traveller’s secret weapon. Here is what it does for you on a long-haul journey:
1. Stabilises Energy Levels
Protein slows the absorption of carbohydrates into your bloodstream. If you pair protein with whatever carb-heavy meal is served, you avoid the sharp spike and crash that leaves you nodding off over your book.
2. Keeps You Fuller for Longer
Have you noticed you’re hungry again two hours after an airline meal? That’s because there’s no protein to keep you satisfied. A protein shake or bar bridges the gap between terrible meals.
3. Supports Sleep Regulation
Protein contains tryptophan, an amino acid that helps produce serotonin and melatonin—the chemicals that regulate sleep. A protein-rich snack before you plan to sleep can actually help you rest better at 35,000 feet.
4. Protects Muscle on Long Flights
Sitting still for 10+ hours isn’t great for your body. Protein helps preserve muscle mass during long periods of inactivity, so you don’t step off the plane feeling weaker than when you got on.
The Perfect Travel “Kit”
You can’t control what the airline serves, but you can control what you bring. Here are protein-packed items that slip easily into carry-on luggage:
- Protein Sachets: Single-serving sachets of protein powder take up no space. Just add water (or the airline’s bottled water) and shake.
- High-Protein Bars: Look for bars with at least 15g protein and minimal sugar. They don’t require refrigeration and fit in your personal item.
- Jerky or Biltong: Shelf-stable, pure protein that actually tastes good. Just check customs restrictions if you’re travelling to certain countries (Australia and New Zealand are strict).
- Nuts and Seeds: A small bag of almonds or pumpkin seeds provides protein and healthy fats without taking up luggage space.
How to Time Your Protein for Maximum Benefit
Here is a simple plan for your next long-haul flight:
| Time | Action |
|---|---|
| Before the flight | Have a protein-rich meal at the airport (eggs, Greek yoghurt, or a protein shake) |
| During the flight | Sip water and have a protein bar or shake between meals to avoid energy dips |
| Before sleeping | A small protein snack supports overnight muscle repair and sleep quality |
| On arrival | A fast-absorbing protein shake helps reset your body and beats the arrival slump |
