It’s improved my blood glucose levels from ~99 to low 90s on average. No other factors have changed.
i've run also a bit higher a1c since my teens. 5.3-5.5 or so. adding fruit to my carnivore diet pushes it tiny lower, ,keto higher. but all other markers are good. i think this is one of the few tests which should be followed according to typical lab ranges. unlikely that you will have low insulin and a diabetic a1c.your thoughts on HBa1c? ( I will do the insulin test next check up 6 months.)
