Just a quick FYI for those who don't know.. Bio-Electrical Impedence can be rather inconsistent. It works by passing a very low-level electrical signal through your body, going in on one foot. Then measures what comes out the other foot. The difference is the calculated impedence, and they use an algorithim to give you final numbers. That's the tingling you might get when standing on it.
Sounds fine, but unless your body is in the same condition every time you measure, your numbers will be out of line and inconsistent. Everything from how wet your feet are, to your bodies hydration level, to how much food you recently ate, can impact these numbers.
If you're looking for a way to weigh yourself, this is fine. But if you really want to know your bodyfat %, see a Doctor or clinic. Or get a set of quality BF calipers and measure using a 3 or 7 point skin fold. Not the $5 calipers you can sometimes find for free, but a good set that prevents over-squeezing, which can also change the numbers. It's also best to have someone else use them on you, when you are relaxed.
That is all I have today, thank you for reading. Stay healthy, stay happy, but most importantly...Stay Classy!
