Greek yogurt

This tangy creamy yogurt is loaded with calcium and boasts plenty of proteinnearly twice as much as regular yogurtto keep you feeling full throughout the morning. Your best bet: Choose a plain nonfat variety and add some fruit to give it some sweetness and flavor (and a dose of added nutrition).I love Greek yogurt because its really quick and easy Giovinazzo says. You can always take it with you on your way out the door.
