DXA precision and the least significant change for lean mass — what changed since

Maintenance phase: tracking body composition during maintenance (weight stable) is different from tracking during active loss. Changes are smaller and precision becomes more important.

DXA precision and the least significant change for lean mass — what changed since — setting out what I have, and where I think it stops being reliable.

Maintenance rather than loss, which is the part of this that almost nobody writes about.

I have been at roughly the same weight for 10 months. The interesting questions are all different from the ones I had at the start, and the documentation here is much thinner on this phase.

I would like to compare notes with people who are further along, and I would like to know what the published evidence says about this phase specifically rather than by extrapolation.

Comparison to published data: the trials reported mean fat and lean mass changes. Individual results vary around that mean. Being above or below average is not a sign of something wrong.
