It doesn't have to be hard.

Though this picture might look intimidating and maybe not even appetizing if this sort of stuff doesn't float your boat but simplicity is the base. Being simple in our mind and choices, especially with food. A bowl of blueberries, strawberries, and walnuts would keep you going longer than you think; try it for 3 days and you'd be surprised at your energy!
Changing out small items for healthier ones (chocolate for raw cacao, Greek yogurt for sour cream, avocado for mayo are examples) can propel you into nutritional nirvana!! Makes you WANT to keep finding delicious foods that are nourishing & instant mood lifters :)
Pack snacks! This helps :) I'll be forcing myself to blog on snacks soon!

Banana w/ almond butter, chia seeds, decadent blend of coconut, cacao, flax, and chia, and honey. I sprinkle maca on mine but not the kids :)
