Believe it or not, following a low-fat diet is not the best way to reduce belly flab. “People who have a big middle do not respond well to a low-fat diet,” says Mehmet Oz, M.D., Vice-Chair and Professor of Surgery at Columbia University and host of The Dr. Oz Show. To reduce belly flab, Dr. Oz advises avoiding refined carbohydrates that are low in fat (like white rice) and can have a yo-yo effect on blood sugar. Instead, add “good fat” foods, like olive oil, avocado and sea bass. Dr. Oz recommends toasting Ezekiel bread (or another sprouted 100-percent whole grain bread) and topping it with avocado, olive oil, lemon and chili flakes for a belly fat-fighting meal or snack.
