To be honest I am a little lost on all this - everywhere you look on the internet, more and more people are talking about hyper-insulinaemia as contributing to practically all diseases.
I really do not understand why we are not simply saying High Insulin is a DISEASE, check yours,
Your fasting insulin should be circa 2-6 uiU/mL or 12- 40 pmol/l - if its not DO something- REDUCE carbs
If its too high you will be prey to dozens of symptoms, of which one of the last to manifest will actually be diabetes, the others will be - cancer, CVD, alzheimers, stroke, PCOS, infertility, impotence, allergies, MS, inflammatory conditions, coeliac disease, food intolerances , sepsis, blindness, carpel tunnel syndrome, frozen shoulder, brittle bones, liver disease , kidney disease , mental anxiety, depression, snoring, sleep apnea etc etc etc.
We should be saying Insulin is the most potent thing in the human body, we all need a bit of it but not much and if you have too much of it, it needs to be got rid of - the easiest way to do that is to cut down carbs as a proportion of your diet and in absolute gram terms that way you will both manufacture less and if your own is deficient in some way will need to inject less of it. .
It doesn't matter where you are on the spectrum of identified health conditions - getting that one number down for which there is an EASY route will improve your overall health.
