I have some physical understanding, but how can they tell my body fat % and how accurate os that?
In: Technology
They have metal pads that you stand on while bare-foot. It puts some small amount of electricity through your body, measures how much goes through (the “resistance” of your body), and estimates your body fat percentage based on the results.
It’s reasonable accurate as long as your body fat is, uhh, normal. If your body fat is in unusual places – perhaps as a result of medication or surgery – then the estimate may be off. As with all things electrical I suggest making sure your body is completely dry. But if you’re using it daily or weekly to measure your weight loss/gains, the general trend of going up or down will be fine.
