I actually had some fasting glucose tests done recently (different labs)

20.10.2020: 92 mg/dl 23.10.2020: 91.5 mg/dl

Both labs give around 70-100 as a normal range.

Would you suggest something more?

I had glucose tolerance test done around 2 years ago (glucose&insuline tested before/after consuming 75g of glucose; sample taken at 0h, 1h, 2h). Looks like I have "insuline resistance" which prompted me to eat more vegetables and lose some weight, but I need to admit that it's hard for me to give up on fruits and sweets.
