    how accurate are smart scales?

    how accurate are smart scales?

    Just a quick question about the accuracy of smart scales, I am trying to calculate my maintenance and most formulas put me around the 2125 calorie mark. However, my scales suggest that my maintenance is around 2445 calories. Thus this has got me wandering how accurate are smart scales?

    Age:32
    Height 5ft8inches
    Weight 62kg
    Activity Level: Light activity (4x a week in the gym plus a little sports)

    There is no electronic device in existence that is accurate with regards to measuring things like daily calories, bodyfat, etc. The only thing they're good for is your actual weight, other than that they're just expensive gimmicks.
    All it takes is consistency, effort, proper nutrition, good programming, and TIME.

    Yup. This.

    My scale claims I’m like under 6%... yeah right
    The power of carbs compels me!

    Just for fun OP, step on to your smart scale holding a 5kg weight in your hands. It will probably tell you you've gotten a lot fatter...

    Even if they could predict your BMR with great accuracy, they don't know your daily activity levels. The only practical answer to finding your TDEE is to eat a consistent calorie intake and weigh yourself everyday for at least 2 weeks. If your weight stays the same, that is your TDEE. If you lose a lb a week, you are 500 under. etc.

    So inaccurate as to be completely meaningless.with a margin of error so broad that your own wild guesses are just as valid. Same with callipers.

    Once I Had a calliper measurement of 13%, a smart scale measurement of 17% and in reality I was around 25%.

    If you want a rough idea of your actual bodyfat post a picture in the bodyfat estimate thread in the losing fat forum (this is still just an estimate but likely to be much closer)

    Scales can tell the truth of your actual bodyweight within a fairly small margin of error

    Your bodyfat scales are only telling you the truth (if they even are) by coincidence, not because they are accurate.

    How could you have actually been 25% with a caliper measurement of 13%?

    Just kind of surprised because the difference between 25% and 13% is huge. At the former, you'd likely have a gut, a second chin, and very little definition, but 13% is getting close to competition shape and you'd probably be vascular with striations and no conspicuous fat. How could there be that kind of margin of error?
