Not a lot, and I never did really.
People will always have different approaches that mirror their personalities and outlook.
I had no desire to experiment with my health. I knew what foods I had to remove from my life, and did that. I didn’t fiddle around the edges to see what, or if I could get away with eating.
It worked for me, but I would never assume it would for everyone else.
I used to test my FBG every day, then changed to testing late afternoon early evening, when I hadn’t eaten for a few hours.
I now test on average once or twice a week, except when I choose to eat more carbs, like I am this week on vacation so I test after eating to ensure I can continue doing it without harming myself.
