All good here, and Pika has given you some excellent advice that is far better than mine!

One thing to remember:

Carbohydrates and protein have approximately 6 calories per gram. while fats have approximately 9 calories per gram. To increase calorie density, increase the amount of fat. That's why several of us have urged you to add fat to your meals in the form of olive oil, clarified butter, nuts, nut butter.

Good luck, and have a great trip! I hope you'll give us a trip report when you get home!
