20 months in and FFMI is still the thing I get wrong

Discussion Clean Column ×5

20 months in and FFMI is still the thing I get wrong. Posting the boring middle of the process, because the internet is full of the start and the end and nothing else.

Figures up front so nobody has to dig: 20 months.

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.

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.

Happy to answer the boring questions. Those are usually the ones worth asking.

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

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

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

nothing on this board is a training or nutrition prescription

Agreed — and same machine, same conditions, or the two scans are not comparable.

the appetite effect makes eating enough protein a logistics problem
