[Discussion] can we stop arguing about FFMI until somebody posts a number

Discussion Long Haul ×1

Trying to settle this properly because the thread from last year went in circles.

The claim: resistance training matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 14 months without either producing anything.

What would actually settle it is 31 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.

If you have data, post the data. If you have an opinion, flair it as an opinion.

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

Removed a chain here. The rule is one line long and it is not negotiable.

lean mass retention is the 84 week conversation

Yeah, protein matters on rapid loss.

What was the batch number and which service?

resistance training is sarcopenia not optional

u/dario_stanescu7 points·7 months ago

Sceptical. If this were true we would see it reflected in the data and we do not.

sarcopenia is the unsolved question

sarcopenia is the unsolved question

Disagree on that part. 98.7% and 98.9% on the same vial is normal.

protein DEXA, not "lots"

You have restated the marketing copy. What is the actual substance here.

protein targets in g/kg

Adding to this: DEXA is doing more work than the comment implies.

The fatigue was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.

This is the "correlation is mechanism" thing again. You changed three variables at once.

DEXA is the real measurement

u/nikhil_asante2 points·7 months ago

This is correct. DEXA is the standard.

body-composition claims need a method

The muscle cramps was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.

The muscle cramps was genuinely awful for three weeks and then simply stopped.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
