Hi Aequalsz:

Post #9647:

" Hi folks:

This US Navy publication seems very helpful for estimating BF%. It

uses height and (abdomen circumference minus neck circumference).

The article supplies equations - if that is what you like - or tables

if you do not like equations.

I doubt we will find a source that is appreciably better.

Note that for males abdomen circumference is measured horizonally at

**navel** level, and neck circumference below the adams apple sloping

down somewhat from rear to front. All measurements are in inches.

http://www.bodybuilding.com/fun/kurilla5.pdf

Also of interest, from other sources: (at least in the case of

males) each one inch decline in abdomen circumference is associated

with a decline in BF% of almost exactly 2%.

Take for example an individual who, let's say, has an abdomen

measurement of 36 inches and a BF% of 20%. Then at an abdomen

measurement of 35 inches his BF% would drop to 18%.

So, in order to drop his BF% from 20 to 10 he would need to reduce

his abdomen circumference from 36 to 31. "

So what level are we trying to get to? Your guess. Not talking submarines here.

Mine is maybe 25%, maybe 18% if I use covert bailey's calc.

I found this site for calculating body fat based upon the U.S. Navystudy. Probably already been posted on this web site, but I couldn'tfind it when searching the archives.http://www.lowcarbnexus.com/articles/bodyfat.htmlAequalsz

My Tanita, set to :adult " says 6%. I started with it set at athletic mode,

and it would read either 0 or " error. " I'm too lazy to do more than stand

on the scale, so I don't have a correlation with the Navy method, yet.

Perhaps I'll get around to it if I get bored over Memorial Day Weekend....

Hi ,

BF seems to be a fitness thing. I can't find a ref to lifespan. Okinawa book says a review of sources indicates 10 to 20 % body fat. But BF looks like it can vary a lot, and I wonder if the impedance measurement is maybe the best comparison number. I have a device that measured my whole family nearly the same 25%, from a 110 # female to a 215# weightlifter.

I just don't a good feeling it means anything for longevity. I'd like to see a correlation of BF to BMI, because guys like Vasily eev had a large gut and set Olympic records (>500#) for overhead lifts. I estimate his BF at 25% using Navy equation.

Accumulation of fat is so easy that managing to <100 kcals is necessary and still I know there must be wasted calories. If the body tucks away 100 kcals per day, that could be 8# of fat, pure fat, per year. I averaged 2# per year for 20yrs in weight gain, but how much fat? .

Looking at the navy equation if I lose 1 inch in girth that's 1.7 % BF, but that can't be 1.7% of say 180 # = 3 #. Point being that it's weight I want to lose - not body fat.

AND, the weight I've lost - 54# corresponds to 7 inches in waist, 2 inches in neck. That's 7.7 # per waist inch, with a drop in calc BF from 33.9 to 25. Seems it boils down to weight and waist inches anyway.

Regards.
