[Question] how do you actually verify DEXA
Slightly embarrassed to be asking this, but: how do you actually verify DEXA. Three scans over eighteen months, same machine, same conditions. Only the third one made the first two interpretable. On comparing yourself to composition figures from trials. Published composition data comes from supervised populations…
a single DEXA is a number, two is a comparison, three is a trend
Correction: those scans are from different machines, and the difference you are describing is within the measurement error.
DEXA has a real error margin and people quote it to one decimal
Agreed — protein and resistance training. Everything else in these threads is a rounding error on those two.
the same DEXA machine or it is not a comparison
Retitled — the original claimed a composition change the scans cannot distinguish.
Yes. Lean mass change during weight loss is expected; the useful question is the proportion, not whether it happens.
Retitled — the original claimed a composition change the scans cannot distinguish.
Agreed — and same machine, same conditions, or the two scans are not comparable.
Compared two scans from different clinics and panicked over a difference that was inside the error margin.
Retitled — the original claimed a composition change the scans cannot distinguish.
This is the whole intervention. Protein and resistance training.
Correcting myself upthread: 13 months between scans, not the figure I gave.
Careful, that is a nutrition prescription aimed at another member and this board does not do those.
