The Airport Lesson
You’ve been up since 4:00 a.m., sprinted through TSA, and finally made it to your gate with just enough time to grab a muffin and coffee. A few hours later, somewhere over Kansas, you’re restless, hungry again, and wondering how one muffin could disappear so fast.
That was me on a cross-country flight years ago, staring down the snack cart and realizing I didn’t need another caffeine hit. I needed better fuel. That’s where understanding macros comes in.
What Macros Really Are (and Why They Matter)
Macros, short for macronutrients, are the three nutrients your body needs in the largest amounts: protein, carbohydrates, and fats. They’re the building blocks of everything your body does, from staying alert in meetings to powering you through hikes, tours, and late-night city walks.
Think of macros as your body’s three currencies:
- Protein builds and repairs.
- Carbs fuel and sustain.
- Fats stabilize and support.
When you understand how to balance these currencies, you stop reacting to hunger and start fueling with intention. It’s not about restriction. It’s about balance that travels with you.
Protein: The Builder
Protein is your body’s repair crew. It helps rebuild muscle, supports immunity, and keeps you satisfied between meals.
Travel example: If your day involves 20,000 steps through Lisbon or a ridge hike in Banff, protein helps your body recover so you can do it again tomorrow.
Easy wins: Jerky, Greek yogurt, tuna pouches, cottage-cheese cups are perfect for a travel cooler or an Airbnb fridge.
Pro Tip: In restaurants, make protein your “anchor.” Whether it’s grilled fish, chicken, tofu, or eggs, build your meal around it instead of treating it like an afterthought.
Carbs: The Traveler’s Turbo
Carbohydrates are your body’s go-to energy source—the fuel your brain and muscles burn fastest. But not all carbs are created equal.
- Simple carbs (pastries, sodas) burn quick and crash hard.
- Complex carbs (fruit, oats, rice, beans) give you steady, reliable energy.
Travel example: On a full sightseeing day, start with oatmeal and fruit, maybe topped with almonds—not just a pastry. That combo gives you endurance without the midmorning crash. At the summit before heading down, a banana or granola bar can provide that quick boost when you need it most.
Mindset shift: Carbs aren’t the enemy. They’re the energy currency that keeps you exploring longer and thinking clearer.
Fats: The Sustainer
Healthy fats don’t just help you feel full. They’re essential for brain function, hormone health, and long-lasting energy.
Travel example: Ever notice you’re hungry again an hour after a carb-heavy snack? Pair it with a handful of nuts or a drizzle of olive oil to extend your energy window and smooth out the blood-sugar curve.
Global favorites: Avocado in Mexico, olive oil in Greece, salmon in Scandinavia, coconut milk in Thailand, every region has a signature source of healthy fats.
Pro Tip: Don’t skip fat to “save calories.” It’s what keeps you satisfied and steady when your schedule (and meals) are unpredictable.
Alcohol: The Wild Card Macronutrient
While we usually talk about three macronutrients, alcohol technically counts as a fourth. It provides calories but little nutritional value, hence “empty energy.”
Everyone approaches alcohol differently. Some abstain entirely for health, personal, or performance reasons. Others enjoy a drink on vacation or at dinner as part of the experience. Both can fit in a balanced lifestyle—it’s about knowing your body and your goals.
What matters most is awareness. Alcohol can temporarily disrupt hydration, sleep quality, and recovery. That might not be a big deal on a relaxed beach day, but it could take a toll if you’re catching an early flight, hiking, or working through jet lag.
Bottom line: There’s no universal rule here. Whether you skip it or savor it, make the choice that aligns with how you want to feel later tonight—and tomorrow.
Putting It Together: Building Better Travel Meals
Once you start seeing food through the lens of macros, even quick meals become more balanced:
- Airport breakfast: Yogurt parfait (protein), fruit (carbs), and a handful of almonds (fat).
- Road-trip lunch: Whole-grain sandwich with turkey, veggies, avocado, and hummus.
- Dinner abroad: Local fish, seasonal vegetables, and roasted potatoes, plus a glass of wine if you’d like.
Rule of thumb: If you can spot all three macros on your plate, you’re probably fueling your day right.
The Takeaway: Eat Smarter. Travel Farther.
Macros aren’t about being perfect. They’re about being prepared, while practicing balance. When you start fueling intentionally, food stops being something you “fit in” between flights or meetings. It becomes your performance tool, your recovery strategy, and your connection to every culture you explore.
Whether you’re trekking Patagonia or navigating a week of back-to-back work trips, the principle stays the same: fuel well, feel better, and go farther.
