One thing: don't go by BMI. My BMI says I'm overweight and at an increased risk of heart disease, diabetes, and cancer. I'm < 12% BF and my blood-work begs to differ.
If your doc is hung up on BMI, explain to him or her the limitations of such a study. If he or she won't listen, then find another doctor you're comfortable with or ignore their advice about weight management.
If your BF is healthy ( < 15%), your resting HR is good ( < 65), your blood pressure is at least normal ( 120/80), and your labs are all good, then you don't necessarily need to lose weight. Of course, that doesn't take into account any medical conditions I don't know about that your doctor does, so my advice is merely general with my main point being there's no point in trying to meet BMI goals if you have to sacrifice muscle to do so. That's actually an UNhealthy approach.
