Body Fat Percentages

I found this online and it seemed helpful and I'm thinking accurate, but would love for anyone to weigh in on these charts and if they seem reasonable.

My Aria scale said I weigh 122.4 and that my body fat percentage is 25.6%.

Does anyone else use the Aria and know if it is generally in the right ball park with figuring body fat?

The chart has pretty much the same information as is everywhere else. Yes, it's a good guideline.


The scale's accuracy will vary according to how hydrated you are. You have to be well hydrated to get a more accurate BF reading, which means that first thing in the morning isn't the best time to get your BF% number. When I'm using my Tanita (same tech as the Aria) for BF%, I weigh first thing in the morning for weight, and later in the day for BF.

I always weigh in the evening. But that is very good to know about BF% being more accurate in the evening as well.

Due to some medications I take I wake up horribly bloated and that seems to resolve itself through out the day so I rarely ever weigh in the morning since it would be a big bummer.

Cool, then it looks like you're right in the butter zone!

Carly 09-03-2013 04:27 PM

I'm happily shocked. I really thought my BF% was going to be a lot higher. I didn't exercise frequently enough during active WLM- so I thought, but maybe I did better than I thought.

I get very confused visually with the loose skin and whether it is fat, flab, skin... IDK.

Ntombi 09-03-2013 04:29 PM

Well, skin is part of your LBM.

Today I weighed 121.6 and the scale said my BF% was 24.0

Yesterday I was 122.7 w/ BF% 24.6

I'm :stars: does BF% really change day to day? I'm new to this so I really don't know.

Ntombi 09-05-2013 04:25 PM

No it doesn't, but again, using the scales to measure BF% is inaccurate at best. Its (relative) accuracy depends far too much on the level of hydration.

SlimNana 09-05-2013 04:35 PM

Yes Carly, hydration fluctuations within your body will effect the body fat % reading on all those types of scales.

:stars:

Carly 09-05-2013 05:46 PM

Then I'm right, that BF% DOES NOT change daily- especially if one is maintaining. I would think one would need to lose several pounds before it would actually change from 25.6% to 23.1% :stars:

Oh, yes, an hour later I dropped to 23.1%

When using the Navy BF% method, I find that fluctuations in water weight effects my LBM - lean body mass. It increases & decreases more frequently, than my BF%.

My scale doesn't fluctuate that much - maybe .5% at the most from morning to night? Just tracking once a day is good enough for me although various numbers can be so fun. :) You might want to get someone handy with calipers or get a dexa scan done just to calibrate your scale. Calipers would work on you even with loose skin because it will pinch the fat and not include the skin. But somewhere around the results you've got seems about right given your height and tiny frame so it's probably not worth the bother or expense. The skin should really tighten up to a large degree in time - so that's a good thing.

I wish it was as easy to gain a pound of muscle as it is to lose a pound of fat. :( :(

^^^^ here's hoping....

I just wanted to update, since we were talking about BF% scales.

I used my BF% scale yesterday, and it was WAY off. My hydrostatic test has me at just under 50% BF, and my Tanita put me at over 69%. :eek: :faint:

I'm so glad that I knew it was wrong as soon as I saw it, because that would mean I have under 100 lbs of LBM. That would change everything.

Obviously, I'm not saying that everyone's results are that off, but BIA (the technology BF% scales use) can vary by quite a bit, depending on many factors.

Carly 09-10-2013 03:27 PM

I fluctuate between 23% and 25% on my Aria scale. I have no clue if it's accurate. I think the Navy measurement gave me 31%, but I am a horrible measurer. I think the loose skin also throws my measuring off. :dunno:

MagicBeth 09-11-2013 08:37 AM

My scale directions say to measure same time everyday for a month to get a accurate reading. Then take the average.


Maybe you still have yours? Or could google for them.
