One factor that needs to be considered is that when you lose mass, 30-45% of that comes from muscle, the lower end occuring when you are overweight and the latter at a more normal weight range. So you will end up lighter at the end of the weight loss journey then you would calculate. An individual at 15% with the same muscle as someone who has 26% would be quite a well-built individual. Increasing your protein intake doesn't prevent the muscle loss. The only way to do it is to shed the weight in a calorie deficit diet and then bulk up in a high protein, calorie neutral diet.

No. They're complete trash - at least most of the affordable one's. I'm almost 40% body fat and 30% muscle according to my scale with the electrodes. I did some research and the result it poops out is really just a generic BMI calculation - that's why it has you input your height. Height shouldn't play a big role if it is in fact "measuring" your muscle or fat percentage. I'm not fit and lean at the moment, but I'm not even close to morbidly obese and am above average in strength from weight training on and off for years. These scales are a giant ripoff and are not a good weight management tool. Get a real BF% test before you lose weight and get another one when you reach your weight and look goals. Or just go old fashioned and measure with calipers. If you're going to get one of these scales, do a lot of research and make sure there is plenty of evidence that they are at least in the ballpark range of accuracy. Don't waste money on the "affordable" trash unless you're sure it actually works. You're better off measuring yourself and using a reliable old-fashioned scale or at least purchasing evidence-driven, proven products.

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.

My scale gives my values from 21 -23% with daily fluctuations whereas caliper measurements give me 12,5%... Looking down at me, the latter must be more accurate.

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 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.

@Domenic Nicosia well most experts agree that our daily intake of water should be about 8 glasses, or around 1.5-2 litres a day. You can tell by the colour of your urine how hydrated you are, the clearer the better, the darker the more dehydrated. These aren't difficult to monitor and regulate. And I never said that the body fat measurements would be precise, and the manufactures state that their measurements are only a guide/reference. What you should get is something resembling a constant reading, which you may or may not find useful. My point was keeping hydrated and doing a morning pee isn't in and of itself difficult with a little thought.

In my case as I am doing manual measures using pinch methods and also use the scale - it seems my scale is -2% all the time. Right now I'm sitting at 20% and it seems quite tough to get down to 15% I do weight training as well, so my body weight goes up but because of the calorie intake and muscle gain; however it seems I am stuck at the 20% - it varies, the lowest I had was 18% this summer and 21% in December and now I'm at 19%. 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% 😂

There are numerous problems and issues. Basic incorrect statements, e.g., when you drink a liter of water, contrary to what you state your body fat % does go down, because the water is part of your body. However, there are fundamental issues that are not addressed: 1. Does body fat % really make sense and can it be measured? The answer seems unclear, because all measurement methods are based on conceptual theories, no one has ever dissected a human being with precise removal of all body fat to validate the measurements. 2. Actual measurements are based on conceptual theories. The machines you describe are calibrated to correspond to the measurements made by more elaborate machines, using statistical methods. In other words, not only is the actual measurement imprecise and inaccurate, but the number displayed is based on a population study of people of your height and age. The displayed value is therefor subject to the statistical variance of the population. 3. Tough the displayed body fat % value is not reliable, it can be useful as a relative value. In other words, if the average values are decreasing then it indicates that your body fat % is probably also decreasing, hopefully by the same relative percentage.

Doesn't this mean that the upper body is absolutely not measured? So if someone, exaggerated, extremely in the arm, shoulder and chest area muscle builds up, but in the leg area would not change anything, the scale would have to assume a rising weight and thus a higher fat percentage. Or am i wrong here?
duenben 2 months ago
Your calculation is a bit off cause when you lose 25-27% body fat the remaining body fat is slightly under 10% cause of the change of what is 100% 25% of 185lbs = 46,25lbs fat and 138,75lbs lean mass. When 10% should be your Body fat then your lean mass is 90% So: 138,75 / 90 * 100 = 154,17 lbs if we take 27% instead of 25% we are going under 154 lbs, it will be 150lbd Then So the target weight is 150-154 lbs to achieve 10% fat

"Your water content at any given point in time can change dramatically. So you can hop on a scale before breakfast, and say "okay, hey I'm 20% body fat". You could drink a liter of water, or you could go work out, you could hop back on the scale, and maybe your body fat percentage is higher or lower depending on what happened to your water concentration." (3:04) And so it should! OF COURSE if we drink water, our fat % goes down (in direct proprotion to our weight going up, in fact).
Laurel Koeniger
Laurel Koeniger Month ago
Yes, but it's not helpful in any way. Most the water you just drank will just be in your belly, make a big difference on the scale (weigh and body fat), but not actually in how your body is made up (cause the body fat is more consistent). So best would be to just always weigh yourself at the same time, like, after waking up and having peed, or so.

This is dumb guesswork. First of all these scales are calibrated for heavy carb bodies. That is it expects ideal water ratio of 65% for male.... for keto water percentage is significantly lower and thus all calculations except weight is faulty. Also, it is not speed. Speed of electricity is always speed of light. Not sure whether any machine can measure that. It’s resistance it measures.
Micheal Daniels

I appreciate the intent of the video, but your math calculating target weight at around 7:50 is incorrect. You are forgetting that body fat % is measured against the original weight to start with, and against the target weight once you've achieved it. In your calculations you are leaving 10% of the original weight as fat, not 10% of the target weight. So, taking the same other assumptions (the scale is accurate, assume all the weight lost is fat only), you should target 150lbs-154lbs for 10% body fat, not 154-158lbs. If you started at 27% body fat for example, then the 154lbs target you specified for that starting point would leave you at 12.3% body fat, not 10%. (Calculation examples: Non-fat starting weight at 27% body fat=185 - 0.27*185= 135.05lbs. For target 10% BF, calculate 135.05 divided by (1- 0.10) = 150.06 lbs. Whereas, from the same starting 27%BF at 185lbs, the BF% at 154lbs = (154-135.05)/154 = 0.123 , or 12.3%)

Anyone here disagreeing with you is crazy. There are countless scientific websites with sources cited by many doctors that say they aren't accurate. Obviously if you use the scale as you lose weight the number will drop consistently, doesn't mean it's accurate though.

here you are wrong. when you drink water, then your body fat percentage will change. a lot of people do not understand that absolute and relative fat mass is not the same. when you drink water, your absolute fat content stays the same but your relative body fat content goes down. simple mathematics. for people who are slow or do not understand: if you have an absolute fat content of 20kg and your body weight is 80kg ==> 100*20/80 = 25 you have 25% of body fat. if you then drink one liter of water, then you weigh 1kg more ==> 100*20/(80+1) = 100*20/81 = 24,69 so, after drinking 1 liter of water your body fat percentage dropped slightly. now you can throw everything that has been sad about the body fat scale in this video into the garbage. i agree that the accuracy of a body fat scale is not good, especially when only having measurement pads for the feet. because the scale only "sees" your legs and not your belly. but displaying the body fat as a relative number in % instead of an absolute number in kg (or lbs) is stupid in the first place for comparison purpose.

This dude is smart in what he is saying, but looking at him at the end of the video it is clear that his scale's reading of roughly 25% bodyfat is very wrong, his body is over 30% bodyfat for sure, his fat is literally folding downwards. Mainly saying this to show that those scales are bullshit....

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 is heavier than fat). So weight should be secondary, in my opinion, to body fat% as a metric to set your goals to.

I started by collecting % body fat values for a couple weeks and used the average to calculate my lean weight, which won’t change much going forward. From then on I haven’t worried much about the % body fat numbers. I say lean weight won’t change much, but that’s only true if you’re goal is a couple lbs a week or less. More than that and you risk losing lean weight (muscle).

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.

@ChooseFI dexa is the most accurate but still has flaws. muscle can contain glycogen which is the storage form of glucose in the muscle. with every gram of glucose, the muscle also stores approx. 3g of water. that means, if you are in ketosis, then your glycogen stores are low, the muscles look smaller. if you do some carb loading, your muscle glycogen stores blow up with water. the dexa machine can not differentiate that. that results in a different body fat percentage. but maybe the dexa can still calculate the absolute total fat mass (in kg/lbs) right - which i don't know

@ChooseFI - Your waist measurement is useful to measure visceral fat, which is more dangerous than subcutaneous fat. However, you have also ignored the impact of diet and exercise on lean body mass. In my view, the scale readings have no clear relationship to 'real' body values for muscle, fat, bones, water and other components of the body.

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.

Wait... should our height not play a factor here with regard to Body Fat %. I’m 193.5cm (6’3”.5), 81kg (178.5lbs),but on the rest of the worlds working out, that gives me a flat 10% Body Fat. That doesn’t work though, Because my Muscle Mass % isn’t even 50% and I still have visible stomach fat. I don’t look unhealthy at all, I do have a odd body shape in sense. I have a Barrel Chest, and even with the stomach fat my chest still sticks out further by 2 some inches. My entire rib cage is visible before it drop off, and is met by Some fat. I can feel the Six Pack, but like.. it would need to be some 4-5” Deep worth of 6 pack to fill in that void to make it flat...

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.

My experience with another scale is that when I entered my real age (45), it showed me 18%, when I set it to 25, it showed 13.5% (repeatedly every morning, so no one-off error). This really shouldn't happen. Btw, my real body fat was around 12-13% as measured by a DEXA scan. So it seems that my scale is basically looking up a some averages based on age and then this plays a big part in the number it ultimately shows. Yes I know that I can still use it to capture a trend instead of the "real" numbers, but it would be nice to know if the Withings is paying less attention to database averages and more attention to the actual measurement is does. Of course it's also worth adding that such a scale is obviously only capturing the fat on your lower body, since the current flows from one leg to the other, and as such does not say anything about your upper body (just assumes that your upper body has the same distribution). But that is not always the case as different people have different body fat distribution genetically. Me for example always had less fat on the legs than the upper body, quite a bit less so that the average person.

But if you do workout, you lose fat and gain muscle. So you cant say that you need to lose xxlbs of body mass to hit 15% fat. If you are 185lbs and lose 10lbs fat, but gain 10lbs of musce, weight is the same, but your body looks different. Am i wrong ? 🤷🏼‍♂️🤔

The scale will never be the best measure. Fat calipers are the only ones that give you the best measure based off the areas your body tends to store fat, which varies between men and women.

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.

I always take the measurements at the same moment: When i wake up. At least that takes away the variable of timing. Just don't take the readings of BF% too strict. It's a good guide i think. But in the end it's how it looks in the mirror and be happy with that or work towards your goal. And it's a good tool for measuring progress. Good video :)

Absolutely, taking your measurements at the same time and wearing the same clothes reduces variables. But in the end, it is about your health, goal progress, how you feel, etc.

When weight changes, % body fat will change slightly. Not so much. % Body fat = weight of fat/total weight of body. So, when weight increases, given the same amount of weight of fat, % body fat will drop slightly. So, drinking water would show less % fat???

Errr. The part about measuring the electrical signal’s speed isn’t quite right. It’s actually measuring the electrical resistance of the body. But great explanation anyway!

@Stefan Weilhartner depends whether we measure DC or AC. Resistance is fine for DC sources or purely resistive circuits. I’ll have to find out what kind of “signal” these scales use.

no, it is the impedance, that is not the same like the resistance.

One thing to remember when doing weight loss calculations is that you for every 5 pounds you lose roughly 1 pound will be lean body mass. You will have less blood volume, tissue, ect.. So if you lose 5 lbs of total weight only 4 lbs of that will be fat assuming you are eating an adequate amount of protein and resistance training during the diet.

What happened to calculating height and weight to determine BMI? What's so hard about that when these scales are inaccurate by 10-15%?
R B 6 months ago
MrEye4get - BMI doesn’t account for muscle. Since muscle weighs more than fat, a muscular person may be considered obese according to BMI. Nothing is accurate. Just look for trends heading in the right direction. So if for 4 weeks the trend is going in the right direction, be happy. Too many people rely on what these numbers say daily. Trust the trend over weeks, not the daily numbers.

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.

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.

What if I kinda squat then measure, will the fat percentage travel fully.
ChooseFI 5 months ago
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.

Bodyfat%1= fat*100/weight. Bodyfat%2=fat*100/(weight+1). So after drinking 1 litre of water, your weight AND your body fat % change.

As long as the inaccuracy is fairly constant you can easily account for it. Personally I would not be willing to pay a large premium for higher accuracy
Mollie tol

@ChooseFI Ofcourse. Also when the average number the scale gives is 25% for instance, don't take it as "my bodyfat % is 25" but instead meassure yourself again the day after or the week after (and ofcourse take the summary again) and when the scale says 20% for instance, you can relatively accurately say you've lost about 5%. The scale might not be too accurate but the amount the calculations are off by tend to be. Also meassure in the mornings when you haven't eaten anything yet might help, or if you eat around the same amount of calories a day you could opt to meassure in the evening after a full day of eating.
