If you are really concerned about blood glucose levels, or perhaps just want to know what level you have, you have two options.

You can buy a blood glucose monitor, unfortunately are a bit pricey compared to our US counterparts, around $50 at chemist warehouse (US get it for like 10 lol), OR you can get a private blood test done via imedical, an Australian lab which will give you a referral to get a blood test done, costs $12. No doctor needed they mail you a referral just rock up to any lab they take sample and you'll get results in like 2 days. (PM me if you want more details on this).

If you just want to improve general insulin sensitivity and reel in blood glucose levels i can provide an insight as to what steps you can take to improve insulin sensitivity and lower blood glucose.

1 - Reduce bodyfat
2 - fish oil @ 5-10 grams a day (5g should be great for a female).
3 - vitamin D will lead to an improved insulin sensitivity (this can be blood tested as well) - otherwsie 5,000 IU's a day is plenty.
4 - chromium, a mineral our bodys need does wonders for insulin sensitivity & nutrition partitioning.
5 - sleep
6 - cortisol. High levels of cortisol, whether it be from stress, stimulants, etc will lead to increased blood sugar levels, regardless of diet.

Hope this is helpful.
