6. Orange Resolution Smoothie
Several flat belly diet plans suggest that you increase your intake of Greek yogurt as a way to bulk up on calcium. According to Dr. Oz,  “It is thought that calcium can help stop fat from entering your cells, improve your body’s ability to break down fat and help your body carry out fat through your bowel movements.” And according to our calculations, less fat and more poop lead to a flat stomach. Try this smoothie recipe which packs a fruity punch thanks to the mangos, peaches, banana and pineapple, plus the Greek yogurt makes it extra creamy and extra good for your belly.
