Do Smart Scales Measure Body Fat Percentage Accurately? Best Smart Scale 2020

[@BrianMax]

This is why you need to weigh yourself at the same time every day, and preferable first thing in the morning, after you urinate. I use the bodyfat percentage to tell me whether I'm gaining or losing bodyfat.

[@raulramirez449]

I have the withings bodyscale and I can say that no matter how hard you try to reduce variation (same time, same place, before breakfast, after urinate, maintaining clean scale's surface according to its manual) this scale still having a considerable variation for fat percentage, it is just ridiculous a difference of 3.5% in 24 hours, 5.1% in three days.

The problem with comparing body fat measurements, is the results depend on water content, so if you are well hydrated you will read lower than if you are a little dehydrated. Ensuring these external conditions are constant when taking %bodyfat measurements is very difficult.

Heres the Withings Smart Scale: tinyurl.com/yb7ptqak , What do you think can you trust the Body Fat Readout on your smart scale?

[@css20080301]

This video is based on the premise that either of the two values is your real body fat percentage. Any scale I used so far asked during set up whether I am “athletic” or “normal”. Based on the answer, the body fat percentage displayed changed by 5-6 points. I’d like a scale that tells me my body composition, not me telling that to the scale. And with that this calculation becomes moot - besides that some additional mathematical shortcuts are taken here (after dropping 15% you have 10% fat of your original weight left, but not 10% of your “new you”... more like 11-12%...). For me, I am using a body fat scale only to see whether I go in the right direction, and for that I only measure at the same time of day. I ignore the absolute value. I will never know whether I truly reach 10%, but if I did I’m pretty sure it would not make me a happier person. Looking in the mirror works much better for that.

[@bogdanznakharenko1613]

it is not about signal speed, electric speed is constant (for cases like human body and simple scale), it is all about resistance measurements

[@stefanweilhartner4415]

it is a bit more complicated like that. the body has a "complex resistance". that means, that the resistance is frequency dependent. this is why we use the term impedance instead of resistance.

[@ephtea614]

Yeah I laughed when he said "speed of the signal..."

[@bensavage6389]

So is it not the speed, but it's the loss of signal that it's measuring to compute impedance? Aka the signal is being impeded by fat muscle water structures.

[@miowacity]

I think it is impedance as well, but electrical signals do go faster and slower depending on the medium the signal is going through. Electricity goes about 10% the speed of light in copper.

[@miowacity]

Impedance is the ability of electric current to flow throw something. Resistance makes it harder for electricity to go through. You are talking about resistance. Functionally they are very similar.

I've been using Withings body scale for more than a year. Results have been very consistent most of the time when I gain or loose some weight. I've lost a lot about 2-3 % of body fat through the year according to the scale, and I believe it's accurate enough.

Hey man, good video and good explanations. Just wanted to add that for bodyfat measurement by sending an electrical current in your body (impedance measurement), the current is going to take the path of least resistance to go from one electrode to the other. This means the current won't go through the whole body, so if you step on the scale, the bf % will be biased towards what's in your legs and maybe lower trunk. If you grip handles with your hands, same story with arms and torso. Unfortunately, fat isn't distributed uniformly in the body, and the distribution is different for everyone. Anyway, all bf measurement methods are wrong, what matters is - as you said - whether they're consistent and can give us a reliable trend.

[@ChooseFI]

Yes, overall it's how your health and fitness levels are trending that matters. When you say all BF measurement methods are wrong, have you looked at DEXA scans? What's your experience with it? Thanks.

[@tortureh2371]

What if I kinda squat then measure, will the fat percentage travel fully.

[@dm4728]

In essence they are useful as a relative measurement at the start of your plan/diet, but as an absolute measurement impedance measurement is useless.

[@jawadhazrat4349]

If scale says you are 15% BF and you dont see 4packs abs than for sure u r not and the scale is wrong. I never trust these scales. It showed 18% BD inreality I know that I am at 25% BF.

Thank you, I was looking for an explanation about how the scales work. It’s really strange, that no one else talks about it. It’s the most interesting part.

[@johnmoore1495]

This is what I do to get the most accurate measurement: 1. Weigh yourself right after you wake up. 2. Weigh yourself naked. 3. Don't eat or drink anything before weighing. 4. Pee before weighing. 5. *This one is overlooked by most people,* only weigh yourself if you've pooped the day prior/have had normal bowel movements. For example I poop at night, so if I didn't poop the prior night, I won't weigh myself as it'll be 1-3lbs higher than it should be. 6. Don't weigh yourself after abnormal days, ie. a night you drank heavily, a day you were exposed to excessive heat or physical work out of the ordinary to you, or a day like Thanksgiving or Christmas where you likely pigged out etc. If you do all of those things you'll end up with a very accurate weight and a pretty accurate body fat percentage if your scale does it.

[@aximaysosa8885]

You information and calculations is very accurate. It gives a general guide as to how to calculate your weight for your general goal. You did specify that when doing them, you assumed that you wouldn't be gaining any muscle mass, but I think people should also keep in mind that when you start working out to lose weight, you are gonna gain some amount muscle no matter what. So yes do the calculations but also realize that your end weight will be higher than what you calculated, even if to lose the percentage you want because at the end of the day percentage is a proportion of fat to lean tissue and if you gain more muscle than you previously had and reached the percentage you wanted, that also means you didn't lose the amount of fat you calculated, resulting inn your total end weight to be higher than you calculated. That why you have to consistently take your body fat percentage, because the amount of muscle and fat in your body will be fluctuating and the only thing that matters is how they relate to each other. This also explains why different body types look, have different sizes, and different weights when considered healthy for them specifically. As you can see, at the end of the day, being a specific weight isn't the goal, but to use the weight as information for an overall analysis of your health for YOUR specific body.

You nailed it. The number is meaningless, but the trend, especially when assessed under the same conditions (first thing in the morning) you can get a feel on the direction you’re moving. The other thing is to get a DEXA and then you can calculate a more accurate assessment based on the future moves on the scale.

[@ConorFenlon]

This is great information for people who aren't familiar with these kinds of calculations. But I think the BF% is a better measurement to set yours goal to, not a weight reading, because as we exercise (depending on how much free weight exercise we do) we also gain weight in the form of muscle (which has a higher density than fat). So weight should be secondary, in my opinion, to body fat% as a metric to set your goals to.

[@genegroover30]

3:41 After drinking a liter of water, "Your actual body fat percentage doesn't change." I believe your statement may be wrong and here is why. Your body fat percentage does change after drinking some water because the water will add WEIGHT which is used to calculate your overall body fat percentage by the scale. With your scale, the body fat percentage change may be a small change due to the amount of water or "the increase in weight from the water that you just drank" but it has changed. Your body fat percentage is a percentage of your overall body composition. The scale is calculating the percentage from the weights of the individual components. It's a very complicated algorithm that determines from the speed of the electrical impulse (like you said) that has traveled through your body, the individual weights of each component. It calculates how much of your total weight is water (which has changed because you drank 1 liter), fat, bone, and muscle. So it must be understood that a change in one component will cause a change in the percentages of all the components. So, your overall body fat percentage HAS changed from drinking the water. The change may be small but it has changed.

[@genegroover30]

@A2B Fit_MMA He shouldn't have used the word "percentage". Words define our communication.

[@stefanweilhartner4415]

this is also the reason why displaying the body fat in percentage rather than in absolute numbers is stupid in the first place. so, if you can not switch the display of the fat content from percentage to kg/lbs then you know that this scale is crap by design.

[@MarksTech]

Also just to add a point more in detail; the more muscle you have, the more fat your will naturally burn. the best way to burn fat in the long run, is to increase muscle mass. as you add more muscle, your BMR will grow. (Basal Metabolic Rate). The BMR is the calories that your body burns during the day, while doing nothing at all. for example, my BMR is 1,496 calories. which means, by doing nothing all day - my body still burns 1,496 calories. if I increase muscle, that number of calories goes up. So to more accurately state how much weight you have to lose to get to a certain body fat - isnt just how much weight you have to lose. you could actually put MORE weight on and still lose fat in the long run - muscle weighs more than fat. so by working out and building muscle, youre gaining weight - but since your BMR has increased, youre also burning more calories throughout the day by doing nothing at all.. now add all the calories youre losing by working out - and soon youll see your body fat start dropping.

If the limitations of these devices surprises you, you never bothered to learn their limitations in the first place. I’m 1.7% higher on these scales than in a DEXA scan. Since I can’t get a DEXA every month, I just use it for trend analysis after being as consistent (time of day, etc). You should also take periodic full body photos and tape measurements with the scale readings. Start seeing veins in your chest and an inch off your waist will likely correlate with the BF readings.

Thanks for the in-depth exploration of scales. However, BF scales that only touch your feet do not exist. As in the technology does not exist. Brands just pretend they do.

I tried a different scale once and it told me I had 24% bodyfat... that was when using pinch I calculated 18% and my scale was showing 16% 😂

[@Antbaca9]

Not sure if you’re still on your journey, but what helped me get from 25% to 15%, was I did strength and cardio, but also a strict meal plan (carefully tune amounts of chicken, green beans, avocado, salmon, rice, yogurt, granola, and protein shake to find out how much you can get each day). I never lost much weight until I did the meal plan and started tracking what I eat. Also, you were measuring around the Holidays - that time of year is brutal for my gains/losses

The measurements are much more consistent if you do them first thing in the morning after you pee lol. I can literally see my weight going down 0.2 lbs/day consistently over several days with a consistent routine. Now if I go out binge drinking or to my favorite Mexican food restaurant there will be some fluctuation. But other than that it's best to be consistent about the time of day you weigh yourself. Another piece of advice I give is to take the median weight measurement week-over-week. This is going to be quite accurate even with fluctuations.

[@onsenguy]

To get good precision on a body fat scale is very simple. Just weigh yourself at the same time of day each time under the same conditions.

If you drink water your body fat percentage does change. Your total weight goes up due to the water but your fat weight stays the same. Therefore your body fat percentage must go down. Same if you eat food. My scales just generate random numbers really, apart from the weight displayed which is consistent with another set of mechanical scales. How do I know? I weighed myself and then again after an hour. No drink, no food, no visits to the toilet. Yes, I breathed out water vapour and probably sweated out some. My weight remained unchanged at 77kg but my fat percentage went down from 33.3 to 28.1. How? My water percentage went up from 45.2 to 49.2. Again how? I can see the fat has reduced over the months, but I doubt my fat percentage is 28. They are Salter scales if you want to avoid them.

[@NotizMe]

The goal weight calculation is simply wrong. It should be: Non-fat weight = ( 1 - percentage/100 ) * Total Weight Goal weight = Non-fat weight / (1 - goal percentage/100) If you want to get to 10% and your are now 185 lbs (turn away from the dark side and use kilograms!) with 27%. Non-fat-weight = ( 1 - 0.27 ) * 185 lbs = 135.05 lbs Goal weight = 135.05 lbs / (1 - 0.10) = 150.06 lbs So 10 % goal for 185 lbs @ 25 to 27 % gives you a goal of 150.06 to 154.17 lbs.

I think that what people often take wrong about those scales is, that it is a good-for-most people product. The deeper you are in a topic, the more you care about things that regular people do not care about. And if this scale gives you a precise result (in regard of its own assumptions), then this gives an orientation to the user. If the user does it more often, it even gives you a tendency (am I losing or gaining weight, fat, muscles, etc.). If you are going heavily into bodybuilding and consider this too inaccurate, use a caliper. A Skoda Fabia is not a bad car, but you wouldn't find a formula 1 driver using it on the racetrack.

Very helpful video.

Yes I wouldn't take it too seriously bit more so of a relative progress tracker. I try to weigh myself with the same control conditions e.g the same time everyday (1st thing in the morning), Never eat or drink beforehand, always use the toilet to empty bowels beforehand etc. Even if it says I'm 20% when I'm actually 23% I know next in the week or two if it says 19% then I have gone down from 23% down to maybe 22% or close to that. So yes I use your method of estimating my goal bodyweight of 12%. However, I don't focus on the scale saying that because nobody cares what a number says on the scale, it matters how you look. So I take progress photos every week and those are more of a progress tracker for my ideal weight and are more encouraging when you see where you come from than an arbitrary number on a scale.

If find these scales very inaccurate, I got a calliper test at my local gym and it measured 13.5% , my Garmin scales said 29.1 % , according to the mirror 13-15% seems accurate .

If the circumtances are fulfilled properly, than the machine rarely gets wrong..

What do u mean bro

[@us00000]

@@RRuthlessMMA you can also use the band to provide it with more info about how much you burned so it will give a close prediction that's how for example the Mi body scale one works

This video is not trustworthy since it has links to scales, most probably earns from it, too. Treat it as an ad.

[@MattDapson]

Nonsense. He perfectly explained the limits to this type of scale. They all faces these limitations. Has zero to do with the scale and everything to do with the tech. Quit being such a cynical d-bag.

[@hashimsharifhobib1738]

Doesn’t take away from the information he’s given, your choice to buy what he’s recommending. Why shouldn’t he make money by offering a product he recommends? Pretty dumb way to think if you think he’s untrustworthy just because he has links to recommendations

Excellent Video on how to Measure Body Fat Percentage Accurately!

[@MrCox2121]

Does an artificial knee or hip replacement skew the signal speed?

[@josedieguez7460]

I use the xiami boxy composition scale 2, and haven't seen any real change from eating or drinking or from 1 day to another.. so i can't say it's accurate, but it's totally consistent.

My scale measures how much water too

[@lobiqpidol392]

Well strictly speaking, if you consider the litter of water you just drank as now a part of your body, then your overall body fat percentage would decrease since the water is filling a larger percentage of the whole body and your amount of fat remains the same.

[@hicoteo]

I went off keto and by body sucked up 6 pounds of water in two days. My scale's app applied those pounds to fat only and actually showed less water! Over the next days the water weight came off. These scales make it impossible to track muscle growth too because and weight inclease is put towards fat.
