[Discussion] the FFMI advice in here is 3 years out of date
the FFMI advice in here is 3 years out of date. It is the sort of thing everyone half-believes and nobody writes down.
The relevant figures are 3 years, and they come from the same log I have kept the whole time.
Protein was the whole problem. Appetite dropped and I was eating well under target without noticing for a month.
Kept the same programme for a year instead of changing it every six weeks. That was the change that worked.
That is everything I have. The rest is opinion and I have tried to keep it out.
best — the order this archive was captured in
DEXA has a meaningful coefficient of variation, and it differs between machines and protocols. Comparing scans from different clinics adds a systematic offset that is invisible on the report.
Left up. Same machine, stated conditions, honest about the error margin.
DEXA has a real error margin and people quote it to one decimal
Cosigning that protein gets harder precisely when appetite drops. That is the actual difficulty and it is logistical.
FFMI is a ratio and it moves when either term moves
Lost slower for six months deliberately and my composition change was not obviously different. Training was what mattered.
Three scans over eighteen months, same machine, same conditions. Only the third one made the first two interpretable.
Small fix — that is fat-free mass, not muscle mass. The scan cannot separate them the way the post assumes.
Small fix — that is fat-free mass, not muscle mass.
Agreed — and same machine, same conditions, or the two scans are not comparable.
That protein figure is grams per day, not grams per kilogram. Different claim entirely.
Disagree — slower loss does not automatically preserve lean mass. Protein and training do the work, not the rate on its own.
What was the rate of weight change over that window?
a single DEXA is a number, two is a comparison, three is a trend
Are you comparing against your own baseline or against a published average?
I would not change the programme on the strength of one scan. The measurement error is larger than the effect you are reacting to.
Compared two scans from different clinics and panicked over a difference that was inside the error margin.
Have the lifts held, dropped, or moved around?

Adding the free proxy — track a few lifts monthly. It costs nothing and it is longitudinal.
Correction: those scans are from different machines, and the difference you are describing is within the measurement error.
the same DEXA machine or it is not a comparison
Yes. Nobody here is prescribing training or nutrition and the good posts say so.
