New here—nurse on nights, A1c won't budge

A1c lags. Eight weeks is one short window.

Not necessarily. If fasting insulin fell that much, I’d want a CGM for two weeks before judging A1c. Morning glucose only tells part.

CGM made me realize my dawn phenomenon was doing more than post-meals. My A1c barely moved until week 12.

I’ve seen the same pattern. My A1c stayed 5.6 from week 4 to week 10 while fasting insulin dropped from 12 to 8. What changed later was consistency, not intensity: same sleep window, same walk after dinner, fewer 10pm screens. At week 16 A1c hit 5.3. Not saying that’s your path, but eight weeks may be too early. If you do CGM, pair it with a food log or you’ll just collect squiggles. I also took a week off alcohol and that showed up faster than A1c did. Sleep and resting heart rate moved first for me.

Same here. The food log was the only reason CGM data became useful. Otherwise I blamed rice for everything.

Waist down 1.5 in and CRP down is real progress. A1c is just stubborn.

I’d track fasting glucose and triglycerides/HDL ratio next. Cheaper than CGM and trends fast.

Did you change carb quality or just liquid calories? That matters for post-meal spikes.

I had a flat A1c while insulin and CRP fell. Turned out I was using two labs; assay shift was 0.2. Repeating at 12-14 weeks same lab helped me see the real trend. Six pounds can lower fasting glucose before the 3-month average moves much. The other thing I’d check is whether lifting increased muscle glycogen and water, which can mask fat loss on scale but not waist. For weekly signals, resting HR, sleep, and waist beat A1c. If you’re data-driven, keep a simple spreadsheet; it stopped me from overreacting to one number.

This is why I stopped checking A1c monthly. It’s a lagging indicator. Waist and energy kept me sane.
