Feedback on lean body weight

I agree with the above comments which express concern about the lean body weight results of your BMI calculator.

Please reconsider revising the presentation of these calculations in order to build better body image in people today, regardless of weight.

I also dislike that you give ideal body weight as a single number as a opposed to a range. No one is perfect and there is a healthy range of
