PMOS (formerly PCOS)
PMOS is driven by insulin as much as hormones, and insulin itself stays hidden. Glucose is the metabolic marker you can actually see. One reading before a meal and one after shows how your body handled it — a direct window into your blood sugar response.
Inflammation
BHB, the ketone this meter measures, calms one of the body's core inflammatory pathways. Watching that number climb is a sign the shift you're working toward is underway.
