Morning snacks/breakfasts are the hardest for on the go situations. Here are some ideas, and something I used to do when I had long days in school:
Protein Sources on The Go:
1) Canned Chicken
2) Hardboiled eggs
3) Make your own protein bars
4) Peanut/Almond butter - higher in fat
5) Canned low fat ham - high sodium
Complex Carb Sources:
1) Whole grain tortilla
2) Whole grain bagel
3) English muffin
4) Sweet potato - you can micro this.
5) Granola
6) Dry Kashi Cereal
7) Micro Bag of Brown Rice - i know, it's not a morning meal.
When I knew I was going to have a long day, I would carry a small thermal bag with an ice pack and carry everything and anything. This is the best way to go. You will have extra baggage, but hey, anything to not sacrifice that hard earned muscle.
PS: How is the MA Nutrition program in U of H? I was thinking of applying, I have my BA of Science in Dietetics, and want to pursue my career and go beyond RD, LD. I want to focus a bit more on sports nutrition, which is my passion. How u like it there?
