[Results] 14 weeks on 5mg, full numbers, ask me anything boring

Results Sourced ×8

Six-word version is the title — 14 weeks on 5mg, full numbers, ask me anything boring — and the rest is context.

14 weeks and 5mg. Those are measured, not estimated, and not rounded up in my favour.

Hydration status and fasting state affect the lean mass estimate. Standardising both is the difference between a comparison and a coin toss.

Fat-free mass index is a ratio of fat-free mass to height squared. It moves when either term does, which makes it awkward to interpret during active weight change.

Please do not ask me what dose you should be on. I genuinely do not know and neither does anyone else here.

Reduced appetite makes hitting a protein target a logistics problem rather than a motivation problem, which is why the practical advice here is about timing and food choice rather than willpower.

Started weighing protein rather than estimating it. The gap between what I thought and what I ate was embarrassing.

Tracked grip strength and three lifts monthly. Cheaper than scanning and directionally the same answer.

lean mass loss during weight loss is expected, the question is how much

How many weeks between the two scans?

That is a trial average in a supervised population and you are comparing your own scan to it.

FFMI is a ratio and it moves when either term moves

Strength retention is an imperfect but free longitudinal proxy: it is affected by neural factors and by being in a deficit, so it tracks tissue change loosely rather than exactly.

I would not change the programme on the strength of one scan. The measurement error is larger than the effect you are reacting to.

Careful, that is a nutrition prescription aimed at another member and this board does not do those.

Retitled — the original claimed a composition change the scans cannot distinguish.

Cosigning that protein gets harder precisely when appetite drops. That is the actual difficulty and it is logistical.

u/dario_stanescu-17 points·10 months ago

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.

strength retention is a decent proxy and it is free
