While long-haul flights will always offer meals to travelers, they’re rarely nutritious or delicious. We always travel with healthy options to keep us satiated in case we don’t love the food options. We always pack high-fat, low-sugar protein bars as well as a mixture of nuts: cashews, walnuts, and almonds. These two snack foods aren’t exactly meal replacements, but they are great options for long haul snacking.
We also try to adhere to the Argonne anti-jet-lag diet or versions of it. We try to stick to a ketogenic diet while traveling, which limits blood sugar spikes and crashes. This means that we eat healthy fats, proteins, vegetables, and fruits or we fast on travel days. We stay away from simple sugars and carbohydrates, which can cause mood swings and drowsiness. The only time that we want to eat a carbohydrate rich meal on travel days is if we’re trying to sleep.
For example, we flew from Stockholm, Sweden to Los Angeles, California, which have a nine-hour time difference. We took off from Stockholm in the morning, which means that it’s the middle of the night in Los Angeles. Since we were on Sweden time, we ate a carbohydrate rich meal on the plane. Then we went to sleep for the majority of the flight, landing in Los Angeles in the morning. Once we landed, we adhered to a ketogenic diet, rich in vegetables, proteins, and fats, which helped us stay awake for the entire day.
