Your BMI is at 17.2 meaning that you are underweight. Your BMI should be between 18.5 and 25 for you to be at a healthy weight. You may want to consider seeing a doctor to investigate why you find it difficult to gain weight, but in general it is important to include all food groups in a balanced diet.
