She would need to reduce sweetened beverages, high carbohydrate foods and foods with added sugar like jams , sweets . Use whole grain breads and pastas , brown rice , aiming to add at least three grams of fiber per serving . Add protein at every meal . A Mediterranean diet is a good option. Also include 150 minutes of moderate aerobic exercise weekly and strength training twice a week.
