This is not medical advice, I am sharing my experience only!

The simple answer is through eating the right foods and exercising consistently. Nothing is simple about it!

It was a work in progress, I gradually changed what I ate and drank over a year. From the time I received better information through my cgm it took about 3 months. My journey was a continuous evolution over a year and a half. I do not eat the same as before and never will again. My numbers stay in the normal range, however, I do not put massive amounts of carbs and refined sugars in my body.

The time that your reversal will take depends on the complexity of your goals and your commitment. The first step is to get the excess sugar out of your body now!
