Be prepared! There is nothing worse than getting super hungry and finding yourself with vending machines and fast food as your only options. Always carry non-perishable, healthy snacks like almonds, protein bars, and coconut water(many times being thirsty is mistaken for being hungry. I definitely recommend allowing enough time in the morning for a hearty breakfast that includes protein. Lastly cooking for yourself is great especially when you have leftovers. Soups, lasagna/pasta, and grains keep for several days and are filling meals without lots of prep time. Bon Apetit!
