Body fat % analysis?

I've heard something called the Bod Pod is accurate. Not sure about the whole ultrasound thing.

Supposedly the body fat scales and handheld electric devices arent terribly accurate.

Calipers you have to be trained how to do properly.

I do my own bodyfat test. I do a plank without a shirt on and look down...If it looks gross..I'm still fat =P

Get a DEXA test done. It's like an x-ray. It's the most accurate way to measure body fat %... even moreso than hydrostatic weighing.

Isn't that one pretty expensive though?

The important thing is that you keep using the same method to test your bodyfat. So, keep that in mind for cost.

sorry, should of said that weights are in lbs and waist measurement is in inches.

heres how you calculate bodyfat. its a bit Maths teacher-ish but its accurate.

multiply your bodywieght by 1.082
add the result to 94.42
once your calculation is done, save this number (BW x 1.082) + 94.42 as result 1.

Multiply your waist girth by 4.15 and save result as result 2
subtract result 2 from Result 1
the result, is your lean bodyweight (your body without fat)

finally subtract your lean bodyweight from your total body weight (total body weight - lean bodyweight)
multiply the result by 100.
divide this result by your total bodyweight = your BF %

so, (total BW - Lean BW) x100, divided by your total BW = BF%

long winded but it works and its free.

I was hoping this was for real.

1) 112.9 * 1.082 + 94.42 = 216.5778
2) 25 * 4.15 = 103.75
3) 216.5778 - 103.75 = 112.8278 lean body weight
4) 112.9 - 112.8278 = .0722
5) .0722 * 100 = 7.22 / 112.9 = .0639504

So according to this my bf% is .06. Did I do something wrong or is this complete crap?

I'm confused as well... what in the world is the "total body weight" The first result? ...?

Dexa Scan is said to be more accurate, because it measures all the fat in your body, including the fat in your brain, bones and organs. Over a period of time, this method can be off as well.

Bod Pod is said to be accurate, but the numbers can be off, due to the temperature in the room or even if the machine has been bumped during the room getting cleaned. Your hair can get in the way of the results.

Dunk Test is said to be accurate, but it can be off as well. I've read a man's blog that had a dunk test done and he says they aren't accurate.

Calipers aren't as accurate as people think they are. The Accu Measure caliper is said to be accurate. It only gives you one site to measure and a card to look at. There's no way that's the correct body fat percentage. Trained people can even be wrong on body fat percentage. I have seen a youtube video, where a trained professional tested a woman's body fat percentage using a caliper and gave her a very low body fat percentage and the woman was bottom heavy, just like I am and there's no way that she had a 14% body fat percentage.

I trust my body fat scale and Omron handheld monitor. I've read where people have gotten tested on their Omron handheld monitor and then gotten a Bod Pod test done and the numbers were the same or 1% off. If my scale can give me my weight, it surely can give me my body fat percentage. If my body fat percentage is wrong, then my weight is wrong as well.

I don't trust online body fat calculators. I know my body and I know the online body fat calculators are wrong. They were giving me 25% body fat percentages and I know that's not my number.

Since you've said that you have a scale, test yourself first, before you to go get an ultrasound, bod pod, dexa scan or dunk test done and compare the numbers.

Looks like you got it right until step 4. It should be:
4) 112.9 - 103.75 = 9.15 X 100 = 915
5) 915/112.9 = 8.10451727
* You have 8.1% Body Fat. You are skinny!!!

I knew I was doing something wrong, but that still isn't right. Oh well

According to this my BF% is 7%...No way in hell....

Your method gives me 137 lbs of lean mass. My DEXA showed 120 lbs lean mass. My BF % as measured by DEXA is 32%... your method gives me 22%... why would I be on a diet if that were true? Sorry... this calculation is off.

For the record, my bioelectrical impedance BF monitor on my scale gives me 31.5%... relatively close to my DEXA.

Edited again to add: I spent $100 on the DEXA.

LOL! I did that tonight..... 4 kids later I have just a lil "loose skin" on my belly. Bleh.

... I don't know where you got this nonsense, but it sounds like rubbish. It appears to be some obscure way to get some form of a BMI. And - as we all know - BMI is a HORRIBLE reference for anything other than returning a useless number.

If you want to get a rough estimate of your body fat on a low budget, find a friend and get some cheap calipers from Amazon or your local health supplements store.

What is this "hair" of which you speak?

A person performing the Bod Pod correctly knows you need to wear a swimming cap and calibrate it between each testing. It's hard to explain, easier to look up but the Bod Pod measures with air volume on your body and lung expansion and air trapped in hair whether excessive body hair for men or long hair for women can mess with the results. Hence the need for swimming caps. I trust the bod pod and callipers over any hand held device or online calculator. There are too many factors that go into calculating the % that the latter 2 just can't test.
