1. If you love smoothies for breakfast, make sure they have fat and protein for staying power.
A slush of fruit, spinach, and almond milk might be sweet and refreshing, but it's almost all carbs. Meaning, you'll either crash or be super hungry in just a couple of hours. Add Greek yogurt, nut butter, nuts, avocado, or your favorite protein powder to your smoothie, and it'll keep you full through lunch.
