why did you not do 4 point scale instead of just leg scale?
“Is to do an autopsy” 💀
LOL YUP
Imma try that tomorrow wish me luck
But u have to be dead😂
@@TyroneBiggums789 I think he didn’t recover from that
@@adriankortmann5048😂😂😂
Measuring trends is more important than the accuracy of each data point. Very well said
Sure, but thats assuming the bias is constant. If its not, then trends measures are trash.
@@alejoforero89 would it not be constant if you’re using the same scale?
@@jonathanlavery bias could depend on other non constant variables. Room temperature, and body weight itself come to mind. Kitchen scales (like Hario) precision varies according to what range of weight you are measuring, the lower the weight, the higher the precision.
@@alejoforero89 , the idea is to have a reasonable range. Nothing is going to be perfect, but if you find the trend going in the direction you want (as noted in the video), what matters is that you're making progress.
So I went into a deep dive (I’m biomedical engineer/physician) I was looking at the variance of the measurements so it turns out it the scales will be off by 10+/- %. With the body scales with their companion app they tend to adjust with time and the variance drops to 5% but it’s pretty much the same algorithm across-the-board for all BIA scales and devices. The tuning comes with the the apps but you have apps like macroFactor that can take in the data and make the adjustments. DEXA even thou it’s not as “precise” it’s variance, is less then 5%. So essentially, if you were to take multiple DEXA scans a week average out the months you’d be within 3% variance. Therefore making the body fat % more accurate. Your other video with the auro strap actually shows a good job of showing the margin of error advertently. So I’d say understanding that BIA algorithms are all the same industry standard id tell you guys buy the cheapest scale you can afford. As for being obese and a fat percentage, above 28 the variance is like 15 up to 25% off. So for those patients I’d suggested going off of weight lost and waiting till at least they get under a BMI of 25 before using a % of fat as any level of measurement of progress.
After checking out so many scale reviews that were not helpful I have to say this one was golden. I really appreciate the straight forward and realistic take on these scales.
Watching this video just confirmed I was thinking about this entirely correctly. Thanks for this! Will be linking to it whenever people are curious.
i hope way more people who look up these scales find this video
Excellent video and perspective - just ordered through your Amazon link - and your mustache dominates. Thanks and happy 2023! Cheers.
Ace video, all information and no waffle. Thank you and greetings from Scotland.
Really informative and well edited video, thank you
Thank you for explain HOW these scales work! I used to always wonder how in the world body fat is measure from these gadgets. Great informative video!!
yessss send it to a friend who might enjoy it too!
Well it’s the 20 dollar scale! Thanks my man this was great help. Love the content.
And here I was searching for the most accurate fat measure. You are right! They are not accurate. What we need is a consistent reading to find the TREND
when you said autopsy you caught me off guard, made me laugh
haha yes! #comedy
Nice video. I think you should test the Huwaei Scale 3 Pro. I have read somewhere that they tested it to have an overall accuracy coorelation score of 0.94 against a DEXA scan, which if true is pretty good.
Wow excellent helpful video! Totally subscribing
Great video thanks for sharing
My scale is being delivered today. Actually was debating on getting that cheaper model scale, but kinda felt like it was a gamble after reading the negative reviews. I opted for the GE one, which is not well reviewed, but GE has put their name on it so fingers crossed! It was still under $50... So glad I didn't hold off to get a more expensive one when there doesn't seem to be any perks to it! Thanks for the info
How's the scale now? Is it accurate, and do you recommend it?
@@maremike2691 I've had a few problem with the connection between the scale and the app. I was able to resolve the issue fairly simply by uninstalling and reinstalling, and all data was still there.
I always weigh twice, bc if I stand further back on the scale, sometimes it reads a couple lbs higher.
Other than those issues, I have very much enjoyed this particular scale and have no other issues. Oh and I've only had to charge it before the first initial use, and one more time, so the charge seems to hold up too, even with daily use.
I don't have anything to compare it to, but i would recommend it.
@@JessClarkArt I just purchased the GE one as well! Did you notice a lot of variation when doing BF% scans when you weighed twice a day? That's my main concern lol im sure the weight scale part works fine
@@shayanpal8077 you will likely always see variations when measuring more than once a day. The body changes throughout the day due to eating, all forms of movement, body release of waste, water, etc. I've found it best to measure when waking up for sleep because many people sleep the same number of hours a night, and there was not much in the form of "exercise" while sleep. Bottom line, measure the same time every day after similar daily intake, exercise, and waste removal.
I still have an Ironman Bodyscale from 25 years ago. The main function of working as a weight scale remains Impeccable and accurate. I can always rely on seeing perfect difference even after going to the bathroom or soaking in a hot bath.
The normal vs athletic modes for bodyfat confuse me, but I take the average of the 2 and it varies a lot depending on hydration etc.
You can use it to check trending lowest bf if you are dieting but I'd point people towards the Navy method and calipers for more reliable bodyfat changes.
Thank you, save me lots of $$$. Happy with my new scale 🙏🏽
$ave dat money!
The handgrip measurement scales should be significantly better since 4 instead of 2 points are used to make measurements. The more measurement points, the more accurate the measurement AND new parameters can be obtained. I would suspect the handgrips would deal with "upper" vs "lower" body types.
Thanks
Dayem that was helpful !!😊
renpho is really good it has been working for me for the last 3 years, I compared it with Gym scales, weight is pretty accurate, surprisingly the body fat also very close, eg 22.1 from gym and 19.9 from Renpho! Wow I am still impressed after 3 years, drawback is it connects to limited apps...
For comparison purposes I'd want to know how much an autopsy costs.
Great review Sir. Very will presented.
Thank you kindly!
Can u please get an autopsy for next vid? Thanks
LOLOL that'll be my last video
I like this video - and your mustache. Thanks!
videos & mustaches for the win! what video do you want to see next?
man grow hair in just 2 mins what a great age to be alive. thank a lot for the info btw
LOLOL #MiddleEastern Genetics
haha! i am scale producer, we supply scales for many brand for many years, actually there is different software for body fat from different factory with different app. that's the reason for different body fat percentage from different brand.
I used a Renpho for the last four years. It was finally giving me issues with under reporting my weight by up to four pounds sometimes and would change when it would do so which frustrated me. I ended up replacing it with a Withings Body+ scale since I wanted something that would hopefully last longer but we shall see. I only paid 52 for mine brand new though so I am not out much more. I do like the Renpho app though.
My Body+ scale just gave out after 1.5 years, so now I’m looking for another brand.
This video was so instructive. Thanks 👍🏻
Renpho user here. Did an experiment by having multiple profile of different height / gender combinations and weight with them, and within 5min my body fat ratio fly from 15% to 25%. Just for fun I weighted myself with the same profile, and then weighted again holding a jug of water, and my body fat flew from 25% to 26%.
Conclusion: the body fat % is just a guess based on your height, body weight and gender, it have nothing to do with a measurement, and the metallic electrode thing is likely just a decoration. It's accurate when...surprisingly, your build is similar to what the app assumed.
I just ordered a withings scale, because I became suspicious of this. I train for 1 year hard in the gym, eat properly, drink a lot, have my hormones in check, bulked then cutted, and when reaching my old weight, the scale said, I had the exact same body fat, to the gram. I hope that the withings scale is more accurate
How about Tanita scales ? Are they same?
great vid
Thanks!! ❤
Good Video. I live right next to your building:) on LSE
Looking for multi-user friendly.. i.e., If two people will be using the scale, how easy is it for the scale to save the data to the appropriate profile/user?
Does the scale or app need to connect to the internet, or is everything done on your local network / app? For example, is the data stored on the phone, or is there some cloud service involved where if the company goes out of business the scale or app won't work?
In terms of data, just something looking to chart weight, body-fat and bone-density over time. But which is the most accurate in the < $50 scales.. RenPho, Etekcity, Withings , Wyze Smart Scale S, Yunmai, ABLEGRID , eufy Smart Scale P2 Pro, Lepulse. Would love to see all these companies send you a scale, and you compare it against your test at Dexafit in Orange County!
Can you compare the old withings tech to the new tech?
I got the cheaper one. 🎉🎉🎉 Thanks for saving me some money.
ofc! i have a new video comparing 7 body fat scales coming out in 2 weeks!! stay tuned for that too
I have a pretty cheap scale that tells you your weight and percentage of fat, water, muscle and bones plus the biological age of your body and your kcal needs. Must be very accurate xD
It only fluctuates in a small range and most of the data is in the range where I would expect it to be. But it always tells me a body fat around 17.5-17.9% and comparing to many pictures online I might rather be around 12-15%.
I probably got the same one! 🤣
I just ordered the Renpho scale. My only concern is, if my wife weighs herself, will it import her data into my Health App?
What app was that, that was taking the pictures?
You can buy a scale that sends a current from your feet to your hands, that's more accurate. I've got an OMRON with a hand piece and it's pretty accurate.
Yes! Just made a newer video comparing 7 diff body fat measuring devices
@@ShervinShares Awesome, thanks for letting me know! I'll put it on my watch later playlist 😁
@@Marco_My_Words woo here it is just in case: ua-cam.com/video/epdwp5ybH5o/v-deo.html
i can tell you the bar handle body weight system is over 10 years old, i had one back then , i did research its accy before i got my new weight and it was awfull off the mark - maby this new system better.
still wouldn't trust all the number 100%
0:33 good lesson , but Renpho and Renpho Health don’t let login into two phone with same account !!!
your hair grew quickly...
DUDE! "After I've released some of the body weight from my body"! Seriously? haha nice
3:37 great euphemism 😆
The App is the make and break for these products
Brooo these kind of scales only can mesure correctly the body fat related with your lower part of your body (legs), if you want a general body fat with these kind of scales you need to buy scales that check the lower part of your body and the upper part (this ones have a cable and "sensors to check your hands" to close the loop of your upper body).
Pleaaaaaseee do another video with expensive and cheap scales, that can mesure upper and lower body to be able to compare it better to the "gold standard DEXA" and the Aura :P
Thank youu!
Binge watch my channel!! ua-cam.com/video/epdwp5ybH5o/v-deo.htmlsi=Y50hSjCioyx9m04E
Thank youu!@@ShervinShares But it is very weird, after writing this comment, I was checking other of your cool videos, and I added a comment here answering myself that I found this video that you shared. I am not sure why the comment is not here, then I checked my History Comments on UA-cam, and I realized that I am missing some comments from yesterday :S anyway, thank you very much your videos are suuuper cool!
I see the value of a trend up or down, but that margin of error is hilariously awful. Wow. Does the actual basic scale functionality work accurately, or is that whacked too?
AUTOPSY?!? DO I HAVE TO DIE FIRST 😂😂 thank you for the video tho! Imma stick with my cheap scale
I'm not sure what you're getting at both gave inaccurate readings but the more expensive one still was much accurate than the cheap one that was 3 digits off.
So your idea of both being inaccurate you would rather go with the cheap one? The one thats obviously much more inaccurate? Atleast the expensive is just about almost on the dot in accuracy.
Products you promote are now defunct. Please do an update! Nakedlabs and Halo for example
Any plans to review the Withings Body Comp?
oooo i have it, i'm doing one comparing like 10 body fat scales
Had to chuckle in the beginning, when he said this is a Nokia scale, now Withings LOL .. cuz it WAS Withings.. Nokia Bought them out for like 7 million? than Withins bought it back about 2 years later for 5 million ( could be off on the millions. but remember they bought it back for 2 million less than they sold it to them for ) ...
For me, bioelectric impedence is way more accurate than Dexa. Dexa 35%. Bodpod: 19%. Calipers 20%. Tape measure: 21%. Hydrostatic: 18% Biolectric impedance: 18.8% Two things: Dexa machines are based on flawed, buggy software (they do quite a bit of interpretation with the limited raw data they collect). Second, they have to be calibrated to be accurate. If the Dexa isn't in a bonfide medical facility, the owners really won't bother with maintenance to make sure it's accurate. That's because medical facilities can get sued for malpractice, were little "fitness clinics" and University athletics departments can't.
Just FYI body fat cannot be measured by scales, even those expensive ones with handles ann stuff. My stepdad is a professional football player and their dumb trainer bought this expensive scale to test their body fat instead of doing BF tests and they figured out its trash. They had this trick where you just spray the bottom of your feet with hot water and it would show much better results.
What was that app that you showed in 3:38 that took pictures of your body from all angles? I would really like to use that to track my visual progress i would really appreciate if you could share. Great vid btw 👍
Not sure the one he was using but there’s an app called Spren which does the same thing
I’m on the waitlist!
1:11 which scale is this ?
bro i bought one for 500€ and it works perfectly, very accurate
How do you know? Did you compare it with an autopsy?
The real Indian Chris Bumstead😂.
- I was actually shocked
- no you fucking werent
These scales are rubbish. Ive been weightlifting and dieting for 3 months. Lost 2kg this month alone yet my scales are telling me I've increased in body fat by 2% Ive never looked so gopd yet my scales are telling me to loose more fat
Luigi looks very difference
what kind of argument is a axe soap bottle placed upon ; right
lol
Nah! I’ll just go for Autopsy!
@Shervin.hey bro you seem like busy man so try things 3 and for your daily habits try streak workout
i know... i'm excessive
I had that cheap scale and it failed at the basics could measure my weight accurately would pick up scale and put it back down and it said I lost 10kg
i have the same scale , it’s absolute rubbish
I come here on youtube to check if cheap scale works good or not after I saw trending weight scale for cheap cheap price, lower than $10..
The design, the look is same as renpo 😂 Im sure they import it from China?
So the scales tend to read higher than what you are
slightly
How is Inbody 270 ?
For the love of all things holy-please DO NOT buy a Fit Track scale. I purchased a scale weeks ago using a code, and I have yet to receive it. When I asked for a refund they created a pre-shipment code instead (that’s still pending) so they didn’t have to issue the refund. It’s been the worst experience and not worth your time or money.
Well at least you got it now.
@@deviction9314 I wish
I have the cheaper renpho scale and have found that body weight has been similar to an inbody and dexa scan. Every thing else has been off. I was pretty surprised to find that all the measurements between the inbody and the dexa were very similar .
Wow! Really good that you found in body close to dexa
Even taking the measurements with a grain of salt will influence them 😎
So, which scale is consistently inaccurate, as in, is almost always off by Y?
Because if a scale is off by four pounds and, say, four percent in body fat/water/etc., and I can watch trends (as you point out), I’m happy with that.
3:38 most polite way to say you've pooped
You look like a Turkish sultan
It must be compared with a scale maintaining full bioimpedance, such as Huawei Scale 3 Pro
Oooo yes! The new Withings scale will also be full bioimpedance as well. Any other brands I should look at?
True. I don't want chinese tech in my house though. :/
Gonna check out Withings later this year!
@@Davidow1 racist
Is it true that dehydration can mess with the measurement?
water, food, etc can all impact measurements
@@ShervinShares I had heard that not enough water can cause a high fat reading
Also if you take creatine right?
What am doing so much data about my body
So basically don't waste money on either one.
I stood on my scale for about 2 hours every day and my weight didn’t change very much. I’m probably better off going to the gym
lol i do the same as you. Early morning after a pee, naked
renpho is a good brand. I could never buy one for 20.
haha
"after I released some of the body weight from my body" 💩
After watching I decided not to even bother buying one of these scales.
hahah yes data is useful, but don't obsess over it
One other way to track body fat is to look in the mirror
Hamza eyer brysh.
These scales are useless when it comes to losing body fat. I didnt lose a lb on the scale for 6 weeks & all of my stats were the same (BMI, BF %, etc...) but when I measured myself i had lost 8" all around, including 3 on my waist lol I knew I wasn't crazy when all my clothes were fitting looser & I felt better. Just goes to show that majority of scales are useless because they don't truly measure body recomp.
What's the name of the app on 3:37 ?
Amazon Halo App with the purchase of the hardware
No scale is accurate
these scales are so off. even the trend is off. it just takes your weight makes a profile gives u x fat x muscle and no matter how you lose or gain weight back when your weight is the same the other stats are the same. i went from 200lbs to 180lbs. went on testosterone gained a ton of muscle lost fat very obviously physically clear. got to 192lbs and my stats were the same fat and muscle when i was 192 losing weight and back up to 192 gaining muscle on test. these suck ! only thing thats accurate is the weight
So which one is most accurate that you used
none of them are, take it all with a grain of salt. new video coming soon
@Shervin Shares lol obviously but which on on average would you say is closest to being right I just bought a rhenpo for like $20
@@skylermccloud6230 honestly that's good enough. just note that it might be a few lbs off. i usually just take the average of my weight from that week. because other factors can influence your weight too
il parle pas chinois que des vérités ici !
wallah habibi both of them are inaccurate ... maybe Dexa scan is the only accurate
Hamza stufy
total waste of valuable time to spend a lot of time with these scales. tooo many variables. Time is soooo important. This is actually ridiculous to do these scales when nothing is really accurate. Obsessive behavour. thanku the info
Just get the cheap opne and pay attention to trends, both are inaccurate and based on same tech/parts
my brother has the expensive one. idk why but it measures complete bullshit. 3 kg bone mass and 60kg muscle mass...yeah sure
yea... none of these are accurate
