To be honest, I have my doubts about testing, even though I did test when I was diagnosed with T2.
Initially I tested to see what effect food had on my BG, and to record my fasting levels.
Personally, I very quickly realised "all carbs are the same" was nonsense.
I could have completely different reactions to them all.
Or even the same ones.
"all carbs turn to sugar", well they might, but I could still cope with ones those that digested slowly, and see a very low rise.
So again, nonsense when related to BG for me.
I produced insulin, I was insulin resistant, but obviously, if it was a slow release of carbs, even my trickle of a response could keep up.
I also realised the less carbs I ate, the higher my fasting level could become.
My liver dump just wasn't producing the same insulin response. Which is a recognised phenomenon, apparently.
But worrying if you don't know about it.
I realised mainly how much exercise helped, and how the effects lasted for days after.
Also I realised just how much weight loss did for me.
I'm not denying I did modify my diet during the testing, but to be honest, the spikes didn't scare me.
Even none diabetics spike.
I have no idea where the"rise of no more than 2" came from. It's certainly not normal.
So I had no problems with rises, as I was chasing the high numbers, and deliberately tested at the times when I would expect to see them.
I just ate, healthily, a classic low fat diet, supported by the NHS
So basically, every piece of advice the NHS had been giving me was correct.
Could I have done it without a meter?
Certainly, and for many I suspect it's probably the best way for them, as for a T2, so many natural things affect our own release of insulin, and our insulin resistance, it's a lot more complicated than simply adjusting the amount of carbs.
And if you worry about the number you see when you test, it's easy to let diabetes take control of your response to that number.
The internet certainly doesn't help to be honest.
I've realised testing was just a broad brush guide, Hba1c, and being free of diabetic complications is my measure.
And so long as my diabetes stays reversed, I can't see anything bad happening.
