reading A1c threads from 2024 and half of it aged badly

Baseline Receipts ×3

Genuinely asking, not being difficult.

Everyone in c/meta repeats that ALT is important. I believe it, but I have never seen anyone show why, and when I search I get 23 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.

Yeah, baseline matters more than any later number.

Same lab both times?

eGFR from 4 to 25 is movement, not noise

Baseline hs-CRP: 99.3. Week 47: 97.9. Same lab, fasted, same time of day. Trend matters.

Crossposting this to c/meta because the people who need it are not reading this community.

baseline is the most important eGFR measurement, you cannot collect it later

ALT is where the fatty-liver story shows up first

ferritin tanks quietly on a reduced appetite, check it

My hs-CRP went from 15 to 20 in 24 weeks. The ALT story shows up in the trend, not the single number.

HOMA-IR is crude but free and useful for tracking

What are your reference ranges?

u/kaia_kuusela1 point·7 months ago

Strongly agree. ALT is where you catch the liver story early.

A1c moves slowly, quarterly is plenty

Do you have baseline to compare to?

TSH from 7 to 9 is movement, not noise

Baseline fasting insulin: 98.9. Week 84: 99.2. Same lab, fasted, same time of day. Trend matters.

Strongly agree. ALT is where you catch the liver story early.

About c/bloodwork

What to measure before you start, what to re-measure, and how to interpret movement without panicking. ApoB over LDL-C, HOMA-IR as a crude free tool, ALT and the fatty-liver story, eGFR noise during rapid loss, and the deficiencies that a 1,100-calorie appetite will hand you.
