Non-caliper bodyfat measurement
 
For those who want a non-caliper method for estimating bodyfat percentage (that's not the BMI method in Rapid Fat Loss or A Guide to Flexible Dieting).

Surprising to me the first and second gave me reasonably decent estimates. I don't remember if I tried the third.

Lyle these are great, but my problem is the variety of percentages you get with each equation, so which one is correct? Based upon your experience, which equation do you utilize with your clients or recommend?

lylemcd 06-20-2008 09:25 AM

none, I use calipers and don't use estimations equations in the first place

the first equation gave me personally fairly close numbers

the 1st link gave me really close results to my calipers measurements. Thanks 4 da link, Lyle.

Hey Lyle,
If you use calipers but dont use estimation equations, then how can you determine the figures? Also, how does one waist circumference measurement determine how much fat is on the rest of the body? Must be more factored into this then what is shown. Thanks.

Because individual's fat patterning is different, relative caliper measurements at specific trouble spots can be more useful than making up a % number based on an equation that kinda-sorta works on populations.

If the caliper numbers are going down, then goodness is occurring. For instance, I only use a mirror and an ab caliper reading.

If my ab caliper reading is 11mm I am fat. If its headed towards 4mm, I am getting leaner. I really don't care about the back of my tricep or my thighs, there is never appreciable fat there on me.

what he said

Makes sense. Thanks to the both of you.

I asked this question once in another post weeks ago, but I think it got lost in the shuffle, so I'll try again.

How much are tape-measurement methods thrown off by loose skin in the abdominal area?

I've lost 100+ pounds, gained it back, and lost it again, so I'm worried the tape-measure reading across the navel is getting thrown off by what seems to me to be loose skin.

The first link had me at a decent/acceptable BF% and I think I "look" that

The second didn't work

The third uses calipers and I don't have any

I used a few others that were like the first that found online and the range was about 2-3% differences/variations. Some included thigh, calf in addition to hips, waist and neck...one included forearm.

I agree that Look is ONE way to be content but I also do not want to fool myself. Also I happen to be a numbers gal and when I see charts and postings about females under 25% I then aim for that. Sue me
