Aim for a diet that’s high in fruits, vegetables, whole grains — those foods are all rich in fiber, which helps combat high blood sugar. Swap regular soda for diet or unsweetened iced tea and request that your coffee drinks be made with skim milk. Better yet, drink water. Lemon, lime, or cucumber slices can add pizzazz to H2O. A healthy diet can help you reach your weight loss goals, and help to keep your blood sugar levels under control.
