I'm now starting see body fat scales that claim an precision
of 0.1% rather than the 1% that earlier ones claimed. If this
accuracy is genuine it looks like a better way to measure the
progress of my diet and exercise program than just weight
alone. But of course, just because they print out a value to
0.1% doesn't mean that the measurement really is that accurate
and 1% is a rather coarse increment.

Does anybody have any idea just how accurate these really are?
If you measure your body fat several days in a row how much is
the jitter? I know that skin and sweat have a large effect on
electrical resistance, for example.

Thanks

now you'll get different responses here, so I'll just give my
opinion. The .1% is probably not true at all. Don't worry
about it. Your body will vary more than that. I find the
reported body fat repeatable as long as I make sure my body is
in the same state each time.. same time of day, same level of
hydration, same food intake.

to do this I only check myself in the morning, after
drinking 1 litre of water, being up for an hour or so,
eating no food, having got an average night's sleep, not
having done any strange stuff the day before (like a huge
meal or a big bender).

it's not useful to compare yourself to someone else but for
sure you can track your own b.f. If mine goes up 1 percent,
I check it the next couple of days. It better go down by
itself or I need to clean up my eating habits (or exercise a
bit more).

I find the numbers do mirror my body shape. Having said that,
you really don't need to have a scale at all. If you're losing
fat, you can tell. I like it cause it gives me something to
write in my journal. Kinda hard to look back in a few months
and interpret "pants are looser". ...thehick

Probably +- 5%, unless you're highly muscled, very overweight,
have dry skin, or in some other way don't look like the people
they used to develop their algorithm. In that case, it's
+-20%. They absolutely are not accurate to a single percent,
much less .1%. The day-to-day variation with hydration and so
forth is easily 1%.

More than that. I had fluctuations from one day to the next of
3-4% on a regular basis. It's doubtful[1] I could gain or lose
5 pounds of muscle in a day. The rolling average was more
consistent, but you would expect that.

Yes. Tanita is the big dog with HealtheTek gaining. I am

I think the supposed claim 0.1% accuracy may be the result of
a misreading of Tanita material. Their most accurate scales
provide read outs up to .1% accuracy. That doesn't mean, and
they don't equal, that the reading is within that limit of
approximation to actual body composition. On its web site the
company claims only accuracy within 5 percentage points.

The reason, I think, for providing scales with far greater
accuracy are twofold: test-retest reliability is much higher
than absulate accuracy; people can use the scales to check
hydration levels, based on just those changes that detract
from reliability.

To claim .1% accuracy would probabily constitute fraud.

While it is true that accuracy of the Tanita scale isn't
"0.1%" (that being nothing more than its granularity), the
fact is that there is no reason to think that the scale
regularly puts out numbers at the far end of its scale of
accuracy! Even though it is accurate to +/- 5%, just like most
measuring devices, most of the time it should be accurate
within a much smaller range, typically around the middle of
the range of accuracy. The quibbling about the accuracy of the
Tanita is seriously over-blown, probably coming mostly from
folks who have a personal preference for -- or perhaps even
OFFER for cash -- other means of measuring body fat.

What isn't clear to me is exactly what the range corresponds
to statistically. The standard error of measurement, the range
of accuracies in 90$ of instances, or what? Perhaps there is
some convention as to the precise meaning of "range" I am
unaware of. In the nature of things, "range" cannot mean the
absolute range, capturing 100% of properly taken measurements.

The point is that the likelihood that any one person's
particular measurements being grievously inaccurate are
incredibly small.

If that's the case, why doesn't Tanita state to what statistic
plus or minus five corresponds. If, say, only 2% of those
using the instrument properly are outside that range (and if
we agree that the 5% range marks the boundaries of grievous
error), you would think they would plainly state that precise
fact, somewhere.

On the other hand, If Tanita vaguely alludes to a "range," the
chances are that range is as narrow as Tanita can get away
with--probably the standard error of the mean. If that's the
case, grievous innaccuracy will occur 32% of the time.

A friend of mine calipered out at ~7%. He picked up an
electronic BF tester . . . it read 40%!

So much for the +/- 5%! Yikes.

Have you asked? Your inquiry is so esoteric, vis a vis what
the general public cares about, that you're not likely to find
that information without asking for it.

> If, say, only 2% of those using the instrument ...

I suspect the only people who would care about that
information are the people who call a scale an "instrument."
I know it IS, but I'm pointing out the vast disparity
between what YOU want to know and what the general public
cares to know.

I'd be as skeptical about the caliper operator, myself.
Dunk tank is the way to go if you care about accuracy to

I had a similar experience -- a wildly inaccurate reading (39%
vs. several other tests estimating me at 25%). To be fair, I
was told that if one is dehydrated, that can mess up the
reading, and I typically don't drink enough water, so that
could have been the situation.

You'd be lucky if these things were 10% accurate, in
the field. Their accuracy claims are under super-ideal
laboratory conditions, and then are STILL over-stated.

In addition, monitoring your BF% and pegging your
strategy to this number is wagging the dog by the
tail. BF% is essentially irrelevant, and is not a
useful parameter to ANYTHING in health/fitness. Fat
has become little more than a Salem witch-hunt, and
low BF% is fraudulently mis-represented as an
indicator of health. The only thing low BF% does is
give people in certain sports an advantage, where
strength-to-weight ratio is important, like
gymnastics. And then only at highly competitive
levels. There was an extraordinary article in a
fitness magazine that I normally wouldn't read, that
showed that of the top 20 female marathoners, the top
o' d'top had surprisingly HIGH BF%!! Go figger.

What people continually fail to realize is that low
BF% makes it very difficult for the body to sustain
muscle!! Very strong highly muscled people--but not
defined--also have quite unimpressive BF% stats. The
combination of low BF% and high muscle is a point of
*unstable equilibrium* in the body, and thus is very
hard to maintain, which is in part why athletes such
as olympic gymnasts have such short-lived careers:
Their bodies from a fundamental metabolic POV CANNOT
sustain the stress of low BF/high muscle for a long
period of time. In general, you are likely to find low
BF% in fact correlated with illness, disease, and
injury--AND, premature aging. And, IMO, oh-so
obnoxious.

Suppose you cut calories by 20% and exercise
vigorously 10 hours/week, and you are still not happy
with your BF%. What are you going to do, cut more
calories and exercise more?? At some point, you gotta
play the hand that is dealt you... by god, card shark
extreeordinaire. Pursue a healthy diet, and
functional fitness--these are the things you can
control. Let the BF% be whatever it will be. BF% is a
very difficult thing to measure, under any
circumstance. Just as well that it's largely useless.
Of course, if you are very determined, you could
biopsy yourself at 5 or so key points, a few times a
year. That ought to be a, uh, howl.

Which is the reason, may I suggest, that marathoners don't
show a lot of hypertrophy--not that distance running
doesn't cause the legs to hypertrophy. At least that's how
it looks to me.

I have often wondered why this seeming truth (regarding the
relationship between muscle mass and body fat) is never
mentioned, making me question whether it was truth. But how
else to explain the fact that athletes' average weight varies
as a function of event or activity. If you could have as much
muscle without as great adiposity, why do tennis players
average about 12% muscle, and not the 6% of a marathoner? Or
the same for sprinters, who require more strength. The
endurance-strength trade-off must determine the optimal body
composition for each activity.

I hadn't looked at it that way, but it might could be.
In addition, of course, to the pure adaptive response:
When moving a limb repetitively for 26 mi, you don't
want it too big. Ditto w/ boxers. Altho definitely
muscular, they don't generally have huge arms--too
much mass to move quickly.

Absolutely. Remember when Oprah hired this personal
trainer (and made him rich), and got down to 110 lbs?
Well, you too would get down to 110 lbs if you ran 75
miles/week. Or signed up for your local
concentration/work camp. It is PURELY a matter of
steady-state equilibrium--calories in vs. calories
out, plus whatever adaptive responses occur. Then,
Oprah got tired o dat crap, and what happenned? Uh,
does the number 205, as in pounds, ring a bell? I
actually bought her book detailing her saga--for a
dollar. I doubt whether she is going to print any
retractions or explain her 205. Which is what makes
the bowflex and other machines such utter bullshit (an
utter bullshit that Jimbo no doubt believes). Those
bodies, as someone else pointed out, are the result of
a CAREER in the gym--a *highly* shifted equilibrium.
Which is why football players, boxers, and baseball
player get fat off season and post-career: A *new*
equilibrium is established. Part and parcel of
equilibrium is diet as well, eating behaviors, and
many other things that are not immediately evident.
Which is the brilliance of the marketing hype and
fraud: By omitting the notion of equilibrium, the
American Pubic(tm) is led to believe they are the way
are simply because they lack the secret, the
technique, the magic equipment (for $39/mo, for half
of forever, at
24.99% annual interest), etc. No. They simply lack the TIME
to invest to effect that *extent* of a shift in steady
state equilibrium. Almost *anyone* can achieve 5% BF. But
at what price??

Nevertheless, One can get good bang for their exercise
buck if they "invest" it wisely and knowledgeably: to
the extent that the average Joe (you'nme) can actually
be *healthier*--but not fitter--than your average
champeen athlete, who quite push their bodies to the
max--like the Ferrari that has to be rebuilt every 500
miles. Toward this end, I have/am developing a system
whereby as little as 15 secs will deliver tremendous
bang for one's buck. I would never make the claim that
YOU TOO will get fit, have abs, ekc. ekc in just 15
SECONDS a day. But I *do* claim that a properly spent
15 seconds can be mighty good damage
control/maintenance--a force in the equilibrium
equation. What's the adage: the candle that burns
brite goes out quick, or sumpn? In that case, I
oughtta live forever!! Equilibrium roolz! Even tho it
is udder bullshit.
