@ Jamie
Whilst only an estimate, there is some logic behind it
When I was 147kg I was 33% bf.
That means 48.51kg
I plan to loose another 30kg. Now 90% of the weight I have lost has been fat…. so of that 30kg I will loose 27kg will be fat.
Taking that away from the fat I’m currently karting around 48.51kg would leave approx 21.5kg of fat.
When I loose 30kg I will weigh 114kg and will have 21.5kg of fat (in theory)
Which is about 18% body fat.
Obviously all this is in theory, as those bf monitors are about as accurate as an unacurate object but I am using the same one, at the same time under the same conditions, so whilst not accurate they should be vaugely consistant.
