Dilemma re body fat percentage
Options

So, I've been tracking my body fat using the Fitbit Aria scale for the past 3 months. In my journey, I've gone from 29%BF to 25%BF.
I recently bought SlimGuide Calipers and they brought my BF to 33.5%. I know Calipers are more accurate.
Here's the dilemma, what do I do!? Which do I use?! There's a significant difference between them! One puts me in average, and the other above average.

You could try taking your measurements with a tape measure and using a body fat calculator based on measurements?0

Are calipers even that accurate.
They all seem like estimates.
I would probably go with the scale just because you have 3 months worth of data.
But have you looked at those bf% example images. Do you look like 25% or 35%?0 -
Calipers in the hands of an experienced trained person using 7-site method are more accurate, as long as the same level of hydrated body is presented to them.
You experienced and trained in using them?
Are you using 7 site method?
Not accurate, easily at best 10% accuracy, likely worse.
Which means it overlaps with the 10% accuracy of your scale too.
Alls good.
As mentioned above - use measurement method too, and then average all these 5-10% accurate methods together.
Use the spreadsheet on my profile page - Weight loss calculator.
Has Bodyfat calc that does exactly that, 2 measurement methods, place to put the scale reading, and skinfold measurements - averages them all together.
Then a Progress tab to track the progress.0 -

Either way, it sounds like you're still trying to reduce your body fat %, so I would continue along that path. At a point, I think that going off of what you see in the mirror/progress pics is more important than a number from calipers or a scale. You're doing great, so keep on going!0

I've had a Fitbit Aria wifi scale for a couple of years, and it's very inaccurate. It sends a pulse up one leg and down the other, then guesstimates your upper body.
All that matters is a downward trend. I weigh daily and sync my Fitbit account with Trendweight.com (it's free, and syncs with Withings, too).0 -

Thanks for that! I do have my measurements taken at the gym for progress purposes and I think they're good to compare along the track, like pictures.

I might stick with the scale only cos it's easier, but I won't rely on it for accuracy lol. Just to show a loss.
Tbh I feel I like more like I'm in the 30s than the 20s.0 -

That's awesome thank you. Will definitely pop over to your profile page and download that.
I guess exact body fat shouldn't really matter. You should just know whereabouts you are and aim for a downward trend.0 -
Also my husband did it for me, we did a 4 site test and we both have no experience whatsoever lol.0

Thanks, you're right! I'll rely more on pictures and tape measurements to gauge my progress.0 -

Yea km starting to realise how inaccurate it is lol. I use trend weight too thanks to you :-)0 -

I'd go with the scales too. Making comparisons to images of others with the same body fat % unfortunately doesn't work so well because it doesn't take into account the % of lean muscle mass, water, bone mass, body composition etc.

@Haybales, whom I respect, says 10% accuracy for the scale.
To me 10% off of a, say, 25% reading, means that in reality I could be anywhere from 22.5% to 27.5%. All kewl and useful.
But, am starting to think that in the body fat % measurement world 10% accuracy for a 25% reading means being between 15% and 35%.
Eyeballing is already way more accurate than that!
I can attest that per DXA scan the scales for me are accurate to 10% as per the second definition, and therefore useless @ 100% ;-)0 -
He means 10 %age points. So 15 to 35.

Yes! I want a DEXA. Hopefully getting one soon.I would probably go with the scale just because you have 3 months worth of data.

Hmm, if that's the case I should be seeing some nice muscle definition coming through soon enough as I continue to lift.0 -

I'll take the first one, thanks!0 -
My Aria puts my BBF% higher than what I was calculating with my measurements. Also, my hydration level can affect the Aria measurement as much as 7%. I'm just using it to show trends now. I don't trust it.

Well I am really excited! I have booked my DEXA scan tonight and I cannot wait for my true BF% haha!0
