1. It's true that BMI doesn't provide a complete picture of a healthy fat percentage, but weight and waist measurements provide even less information, so I'm not sure why you would present that information as if it contributed to your point.

2. Caliper fat measurement is pretty accurate if done correctly, but it's also hard to do correctly.

3. In your own words, no doctor has ever looked at you and said you need to lose weight. This seems to indicate that while BMI isn't always an indicator of health, doctors are capable of identifying the exceptions.
