    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.

      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.

      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.

      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.

    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.

  • @stfuna4b
    @stfuna4b 4 роки тому +99

    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
      @ChooseFI  3 роки тому +16

    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.

    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.

    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.

    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.

    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.

    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.

  • @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 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.

    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.
    Scales like Anker (Eufy) for example typically give you a value that’s off by as much as 100% (as in 25% percent rather than a real number of 13% measure by expensive multi point scales). This is well documented online. And especially true for bigger ppl like athletes and bodybuilders.
    This is DANGEROUSLY inaccurate. It misinforms users to the degree that people are inevitably making unhealthy decisions thinking they need to loose weight.

    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% 😂

    • @Antbaca9
      @Antbaca9 Рік тому

      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

  • @stevencrawford6503

    It's funny because when we went through training we were told these are better then calculating bf% with calipers just due to consistency. Most people in class would have different bf% results for the same person just due to each of us doing the measurement slightly different.

    Got me. After if my Renpho scale was believable. I too noticed the flux in numbers that could not have changed that significantly in just a few hours or even minutes (before after shower). I do see the trend however.
    I introduced much more fat and salt into my diet and carved out a lot of carbs, sugars and completely corn syrup (Keyto). This coupled with an 8hr window to eat (intermittent fasting) and wow did the fat start coming off fast.
    This made me want to exercise more and stretch. Its amazing how a little scale can be a nice daily prompt in the right direction.

  • @Shoebilly_Blades
    @Shoebilly_Blades Рік тому

    So potentially you could track water intake and narrow it down to a smaller window by calculating say 1 liter of water is equal to say a 2% increase in bmi, then subtract that from bmi reading. This is given that it shows a consistent percentage over some period of time.

  • @Kroplexxx

    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?

    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. For example, weigh yourself first thing in the morning right after you urinate. It's the change that's important each time you weigh yourself that's important, not the actual number.

  • @seekerofknowledge6595
    @seekerofknowledge6595 3 роки тому +2

    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.

    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.

    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.

    @yianpap6093 4 роки тому +12

    Simple question: Does the Withings scale change your body fat percentage quote, if you change your age you presumably enter when you first set it up? 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.

    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.

  • @brandonhoffman4712
    @brandonhoffman4712 2 роки тому +4

    Another factor to consider is the amount of other weight that must be lost in coincidence of the fat loss. Which equates to about an extra 20%.
    This constitutes mostly blood and extra tissue that would no longer be required and would melt away with the fat.
    To lose 20lbs of fat you need to lose about 25lbs, so to lose 30lbs of fat you would need to lose about 37.5lbs

    • @stinkycheese804
      @stinkycheese804 9 місяців тому

      That's pretty much inaccurate nonsense. It depends highly on your diet and exercise level. Think about it, the fat doesn't just magically disappear, something caused that loss and the combination of factors that did, influences what the resultant weight is. Better still, forget about the fat weight entirely and just focus on the diet and exercise and it will happen.

    I really like your math. However, I keep hearing people say "speed" of the circuit. Speed has very little to do with it, and the scale doesn't measure speed. The scale measures resistance, and it takes a good bit of resistance shift to create a measurable change in speed in a waveguide. That is how the more complex scales make a best "guess" at visceral and subcutaneous fat, they send various currents through your body and measure the different impedances. I'm certain you can find a chart somewhere that says "x micro amps for muscle, y micro amps for subcutaneous, etc." but they would still be a best guess.

    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.
