Maintenance Mundanities
I'm in maintenance but still whittling down my body fat levels in order to achieve a reasonable body composition. I have very low muscle mass so, although I have a low scale weight and look slender, I have an unwelcome kinship with streaky bacon, except that the bacon has a more favourable fat:lean ratio.
Fat Mass Detail from Repeat DXA Scan

Fat Mass Detail
Lean mass includes all parts of the body (organs, muscle, and fluids) but excludes body fat, so fat mass is everything that excludes organs, muscle, and fluids.
Total Weight: 47.4kg/104lbs (me, in the afternoon, with clothes)
Fat Weight: 9.148kg/20.1lbs
Tissue %Fat: 20.1%
There is a graph that shows where the body fat falls on a Composition Reference Centile Graph that shows my Total Body Tissue %Fat result in comparison to a reference population (in my case, the UK Total Body Composition Reference Population, version 112). There are currently and unhelpfully no standard definitions of normal or obesity based on Tissue%Fat results, but the centile graph allows someone to compare themselves against a reference population. I'm in the 2nd Centile for the group that I most resemble in that reference population data (i.e., the 50th percentile is the median result for a reference population).
Fat Mass Distribution Detail
March 2014 I had 15.729kg/34.6lbs of body fat. For the repeat scan in March 2015 I have 9.148kg/20.1lbs (a loss of 6.58kg/14.5lbs of body fat).
Annoyingly, the Fat Distribution is reported as year on year change rather than in absolute numbers.
While Total Body %Fat is said to indicate something about overall fitness than weight alone, regional fat distribution indicates where the fat is located. It should be remembered when looking at these figures that android and gynoid are both part of the trunk region calculation but do not make up the whole of it.
Android (waist) fat is often associated with apple-shaped body types.
Gynoid (hip) fat is often associated with pear-shaped body types.
Region Region %Fat %Change vs Baseline
Android: 14.2% -13.2%
Gynoid: 30.5% -9.0%
Arms: 21% -9.6%
Trunk: 16% -11.9%
Legs: 25.1% -8.0%
Total Body: 19.3% -9.7%
I have an A/G Ratio (android/gynoid) of 0.46 where optimal for a woman is <1.0. I'm very pleased with the change in my android deposition of fat and can only hope that it indicates positive things about the low level of visceral fat that I have.
My ambition for my next scan is to have reduced the fat levels in my arms and legs. I'd be thrilled to have added lean mass but with my post-menopause status and hormone profile (plus the state of my joints) that is unlikely and I'd continue to do well to maintain my muscle mass without losses.
Maintenance IF 4:3
Dexa scan reports that I have low skeletal muscle mass and I'm categorised as sarcopenic, despite my age and fitness activities: body composition changed from 42% body fat at 127lbs to 20% at 103lbs.
