I still wouldn't trust any scales that have an alarm clock

A close mate and my training / events partner used one at his work and it was way off. He weighs mid 80's and has a BF of about 11% (ab's etc all showing) and it came back at about 16%. Up to 22% is classed as normal and healthy but theres a huge difference between 15% and 10% BF. No bro science needed there.
Dexa scan is the only accurate way. Its used for osteoporsis but it'll tell you an accurate figure and determine how many calories you actually need etc. I use skin folds now and while inaccurate they are guide that i'm going in the right direction.
2.5+ years ago i was 42ish% BF so i've been there and well still l am. It's truely a slow process, none of this biggest loser **** dropping 50kgs in 3 months. 99% will put it back on. I led a very unhealthy lifestyle. Too mucj crap and no physical activity (sound far too familiar in our younger generation???) and amongst other things i remember having to get out of the 50m pool at craigie because i couldn't complete a lap. All that is fkn disgraceful but my point is that i know how it feels.
Ditch the scales, get a dexa scan and take measurements (heaps of drawings on google) and photos to see the improvements. That's what's important.
But squat, there is nothing better than lifting that bar out of the cage and feeling it bending
