Spinach
Packed with nutrients – fiber, vitamin K (for bones), lutein (for eyes), and some research suggests it helps muscles during exercise. It has plenty of iron, which means that can “raise you up” when you are tired.
Orange juice
Vitamin C helps in the production of carnitine which converts fat into energy. Cup fresh orange juice plus enough fruit and vegetables (peppers, broccoli, strawberries) and you will have a lot of extra energy all day.
Bananas
Another miraculous food full of nutrients. Banana will give you energy and will maintain stable blood sugar levels.
Eggs
Protein from the eggs, especially those from white will help you to stay awake and maintain your concentration.
