wrong % body fat in Index S2

You can set the value you want as previous answer. 

But garmin say real fat, all fat brown fat plus reserve fat plus vital fat

And extra fat you have to loose. 

I am 176 cm 72 kg

I could be happy with a Chinese scale and 15% fat

But the garmin with 22% is the real %

Because the minimal to live is 10%

And I have still 7kg to loose

Touch the skin on the back on the legs if you touch fat

You have to loose weight

Or

Your height /2 minus 10%

Should be the the circonferenze of your belly

1. Every cm plus on the belly is kg of fat to loose

thank you!

These answers are absurd.
You work to achieve the body fat percentage "you  want".

You don't just set the device to give you a reading that you want.
This is a device that is supposed to determine body composition.

It simply doesn't.
