Your circadian rhythm is regulated by sunlight as well as meal times. Eat when it’s breakfast, lunch and dinner in your new time zone. Have a light snack before you leave so you don’t need to buy food at the airport, which is often expensive and too processed, making you feel uncomfortable and tired. Bring cut fruits, carrots or granola bars to keep you full and energetic during your travel adventures.
