1) Lean mass is not correct. Two people with the same height and weight can have the different lean mass and fat percent.

2) Ideal weight should be different depends on the frame size

I have lost at least 20 pounds. My doctor says that I have done remarkably well, and to keep up the good work by maintaining the weight I am. My husband is terrified that I will disappear if I lose another pound. But, as far as your calculations are concerned, I am overweight. What is that about?

I'm 5'3" and weigh 115 lbs, which I feel is the perfect weight for my height and (small) bone structure. How nice to see that this puts me at a BMI of 20 and at my ideal weight!

I agree with all the people who said that the BMI weights are too low. At 4'11' I'm supposed to weigh 95 lbs., and my lean weight should be 86 lbs.! Most of my adult life I have been 5'2" but have shrunk in recent years. The weight charts used by Weight Watchers used to say I should weigh 118-120 lbs. at 5'2".

I was not heavy my entire life. I started gaining weight once my back pain was horrible.

I just 2 years before weighed 150 lbs and was told I looked anorexic. Why is that?

Are you kidding me? I'm 60 years old and you want me to weigh 110lbs. I brobably did as a teenager. If I got down to 110. I would be skin and bones. You need to rethink this

That is a wonderful tool to help all of us see how much weight we need to lose as it stands I need to lose 135 pounds. I need to walk more and eat more salads. It would help to exercise often on my health climber. Thank You again. Faith M. Friedrich.

Did not mislead me at all

To provide a counter point to the other comments.

At a BMI of 25.84, I did not "look" overweight. But my blood sugar was higher than what it needed to be, and I was on blood pressure medication. Through diet and exercise, I went down to a BMI of 23.5.

The difference has been dramatic, and I would not have believed it had I not experienced it myself. My A1c dropped significantly, and my blood pressure is lower now without medication than it was before with. I don't "look" much different than before.

For me, this has worked.

An individual's body frame should also be taken into consideration in this calculation. A larger boned person may be able to handle a little "extra" weight compared to a smaller boned person.

misleading, not ideal

I think your declaration of "ideal weight" is too low.

The endocrinologist I'm working with to lose weight says that my goal of 165 isn't realistic (I'm 5'10", he thinks 165 is too low) and your calculator says I should weigh 151.

Anything from 129 to 174 shows up as being in the "normal" weight range, so it seems that your calculator merely shows the mean... which is not ideal for everyone.

And I agree that the "lean body weight" should be changed, perhaps to "lean body mass", to emphasize that it's not a goal weight.

I feel like if I were to weigh the amount it says for my "ideal weight", I would look very unhealthy.

I agree with the above comments which express concern about the lean body weight results of your BMI calculator. It could easily be misunderstood, misinterpreted or used as an excuse to eat less or perhaps even more in extreme cases. As a patient and not a health professional; a person could easily think that lean body weight means how much one should weigh to be lean. Had I misunderstood, I would be thinking I need to lose 32 pounds and I'm 6-0 and I weigh 175 pounds. Perhaps a tiny explanation is in order?

And there is a range of healthy body weights. I believe these two critical errors may cause susceptible girls and women to begin or restart disordered eating behaviours. As someone who is in recovery from anorexia nervosa, as well as a student researcher studying the neurological basis of obesity and satiety, I am very disappointed in how you have decided to display your calculations. Please reconsider revising the presentation of these calculations in order to build better body image in people today, regardless of weight.

To whom it may concern,

I feel that your calculations of lean body weight are misleading and need better understanding. Is this the weight of my body that is not composed of fat or is this the weight I would have to be at to be considered lean. Without further explanation on this page of what this calculation means I feel as though it may trigger young girls and women into thinking they are not lean. 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
