I was diagnosed with type 2 diabetes. My initial fasting glucose was 161 and a1c was 7.1 . Not prediabates, but full on type 2.
So what does the GP say? "Here's some metformin. Oh look, high blood pressure. Here's some statins."
So, what do I do? Certainly not the doctor's advice. He didn't even give me the correct blood-sugar level in which damage is known to be caused (neurons die at 140mg/dL, no ifs ands or buts). Doc said 150mg/dL.
I've posted recently in what I'm doing, but esentially comes down to diet. Turns out that net carbs (or total carbs-fiber) is what causes my body to go haywire. Cutting down to about 10-20g carbs has done well for me.
Since doing only pure diet, 6 days is what it took for my body to start to noticeably fix itself. Now, my blood sugar doesn't go over 120, and my wake-up (fasting) glucose has tested at 100 the last 2 days.
Look up "Eating to the meter". If you can't measure, you can't reliably react and project. It's what I'm doing, and it's working. I have my data to prove it.
