First, we want to reassure you that the foods on our list are delicious. So what makes them "flat-belly foods"? They have four great things going for them: • They’re so low in calories, you can eat your fill. • They’re rich in healthful nutrition. • They’ll leave less room in your stomach for more calorie-dense foods (think desserts). • Prepared in creative ways, they can taste like an indulgence. Case in point: raspberries in a yogurt, brown sugar and Grand Marnier sauce!
