No, you're a healthy weight, according to your Body Mass Index (BMI). If you google BMI calculator, you will find any number of programs that will let you enter your height and weight, and they give you your BMI. The ideal range for BMI is considered to be 20 to 25, and your BMI is right about in the middle of that range. No need to worry. Just eat healthy foods and get a healthy amount of exercise, and you will stay in the same weight range that you are now. If you grow in height, you will naturally gain weight, but it will be proportional. YOU'RE PERFECT!
