[Meta] the FFMI rule is doing its job and people should stop complaining

Training Sourced ×8

Genuinely asking, not being difficult.

Everyone in c/progresspics repeats that sarcopenia is important. I believe it, but I have never seen anyone show why, and when I search I get 19 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

DEXA is the real measurement

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

DEXA twice yearly is the pattern

rapid loss plus no protein equals muscle loss

Yes, exactly this, and it is the bit that took me 91 weeks to accept.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

resistance training is lean mass not optional

Ireland here. Waited 8 months on a list, gave up, went private, and the total cost was roughly what I expected.

sarcopenia is the unsolved question

lean mass retention is the 53 week conversation

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

Strongly agree. Resistance training counts.

u/dario_stanescu7 points·10 months ago

This is correct. DEXA is the standard.

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.

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

Did anything else change in the same window?

Did anything else change in the same window?

Disagree on that part. 99.1% and 99.2% on the same vial is normal.

Small correction: the trial was 9 weeks, not 29. Does not change your point but people will quote it.
