anyone else notice resistance training kicking in around week 92

Discussion The Quiet One ×7 Sourced ×3

Six-word version is the title — anyone else notice resistance training kicking in around week 92 — and the rest is context.

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.

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

Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

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.

Protein was the whole problem. Appetite dropped and I was eating well under target without noticing for a month.

Some lean mass loss accompanies weight loss in any deficit. Resistance training and adequate protein intake are the two interventions with the best evidence for limiting the proportion.

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

protein and resistance training, that is the entire intervention

u/tomas_broberg1 point·8 months ago

Push back: strength dropping in a deficit is not the same as lean mass loss. Related, not identical.

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

grip strength and lift numbers are cheap longitudinal markers

the scale cannot distinguish tissue types and never could

Resistance training, and at what frequency?

u/halima_mbeki17 points·8 months ago

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

training volume matters more than training novelty

u/erez_yilmaz64 points·8 months ago

How many weeks between the two scans?

replysharereportpermalink
u/arne_amankwah35 points·8 months ago

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

Three scans over eighteen months, same machine, same conditions. Only the third one made the first two interpretable.

strength retention is a decent proxy and it is free

nothing on this board is a training or nutrition prescription

the appetite effect makes eating enough protein a logistics problem

replysharereportpermalink
u/dario_stanescu7 points·8 months ago

Right — strength retention is a free proxy and it tracks better than most people expect.

FFMI is a ratio and it moves when either term moves

u/protein_first_pMOD21 points·8 months ago

Reminder that nobody here is prescribing training and the sidebar says so.

replysharereportpermalink
u/tuva_kirchner16 points·8 months ago

losing weight slower does not automatically preserve more lean mass

replysharereportpermalink
u/edit_for_clarity8 points·8 months ago

Yes. Lean mass change during weight loss is expected; the useful question is the proportion, not whether it happens.
