I would really be happier with the 24% reading than the 30% one, though :-)
This is why I say forget these numbers. I would like more money and a longer......... vacation. Because I know what to do with those numbers.
I understand the concept and keeping track of your %BF seems like a more reliable way to measure progress than weight, but it seems to me that on a day-to-day basis changes in weight are easier to understand. Maybe I am just behind the curve. I have no faith in a waist to height ratio as a measure of BF%, but maybe a impedance scale could be good tool.
It's grandma, but you can call me sir.
