Lean Body Mass charts?

The problem with algorithms is that they're not effective for outliers. That's like telling a 6' tall woman that she must really be 5'4" because most other women are 5'4". I don't think most women who weigh 193 have a 32 inch waist and can pick up and carry a 250 lb man.

This is why I need actual data and charts, and not merely formulas.

The thing is this stuff has to exist. The body fat % measuring market is huge. These companies must have done research on actual data to determine the effectiveness of their products. Likewise, all those body composition formulas have to be based on real data and not just other formulas., or else they'd be completely useless. The data must exist somewhere.

I really don't understand the need or why you are looking for this.

If you're genuinely confused about this, I'll explain. And considering how important Lean Body Mass (LBM) is, I think it's worth the time. When you get right down to it, LBM is the most important thing to understand about your body. The rest is secondary.

Muscle mass, organs, frame size, bone density, cartilage, connective tissues, blood, lymph (the clear fluid that fills blisters, of which you have as much as you do blood), skin, teeth, hair - that's what makes up your LBM. Your LBM can change to an extent with muscle building or atrophy, but a large part of it is based on your genetics. The size and shape of your skeleton was determined by your DNA and it will be what it will be no matter what you do.

We already know that a good target Body Fat Percentage for a woman is anywhere from 22%-25%. The only variable is your LBM, and it directly determines what your Ideal Weight is. This is why understanding what your LBM is is so important.

It is fundamental!

I'm asking help in finding data that lists the statistical distribution of LBM values for women by height. And you’re confused as to why. The reason is because the height and weight charts that are available don’t isolate LBM from Body Fat, and don’t show the normal range of LBM for each height. They aren't useful.

The erroneous assumption that a lot of basic height and weight charts have is that everyone has a relatively low LBM. And that's not even remotely true. In acknowledgement of that fallacy, for a long time doctors charts had ranges of weights for vaguely defined small, medium and large frame sizes. They measure things like wrist circumference, which though is a good try, is obviously flawed - because if "frame size" is a stand in for estimating LBM, and LBM is affected by muscle mass, then why are you measuring in a place that does not have any muscle? My wrist size won't change if I gain or lose 50 lbs of muscle. The reason they measure there is that it’s easy and noninvasive. But that doesn’t mean it’s accurate.

The same thing is true for BMI – taking people’s weight and dividing it by the square of their height is easy, noninvasive, and inexpensive. The problem is gives you no useful information at all. It’s completely worthless. Musclebound 10% body fat athletes are categorized as “obese” and 60% body fat seniors are categorized as “normal”. And there’s also no reason at all to square the height – there’s no basis in the science or the math, and it just makes taller people have far higher BMIs than their equally fit shorter peers. The mathemetician who came up with it insisted it should never be used to evaluate an individual and it bares no implication on body fat or health. BMI has been debunked time and time again.

The fact is, I don't need to see another total weight vs height chart or BMI chart that tells me I need to weigh 145 lbs, which for me would be 3-7% body fat and dangerously thin. What I need to see is a chart that shows the normal distribution of Lean Body Mass values for women of specific heights, so that I can determine where I lie in the percentile and better understand my body in the context of the general population. I know that my LBM is somewhere between 130 and 140 lbs at 5’6” tall. What I want to know is – where is that in the spectrum?

How does knowing that help me? It affects the amount of protein I’d need compared to standard recommended diet. It affects my absorption of certain medications, the implications of which can be very serious. And it gives my doctors a better understanding of how I may compare to clinical studies, including the effectiveness of anesthesia during an operation (I was once able to remain conscious and stand up of my own volition once a surgery was completed, because the anesthesia dosage was not effective enough).

When you think about it and all of the implications, what could possibly be more important?
