Trying to lose weight, and you think you have to ditch all carbs? No way! It's painful to live without bread and pasta and fruit, and the best news is you don't have to! Registered dietitian Leslie Langevin, MS, RD, CD, of Whole Health Nutrition recommends eating carbs to give you energy and fill you up. But not just any carbs. Avoid refined carbs like foods made with white flour (bye-bye bagels) and white sugar (sayonara sweets), and go for complex carbs. Leslie says, "They break down slowly in the body because of their high-fiber content and help to keep blood sugar levels steady since they are digested slower. They're also richer in nutrients than simple carbohydrates." Aim for three servings a day of whole grains, one to two of fruit, and one to two of legumes. Here's a list of the best ones.
