@Trevenwith. A belated welcome!!!
I was diagnosed nine months ago with full-fledged T2 diabetes. I'm 60 years old and have never in my life been "overweight" according to the conventional definition (BMI) and although I had put on some weight when diagnosed, I have never got above 21.7 BMI. My morphology approaches that of a stringbean.
When I was diagnosed squarely in the diabetic range I went on a (permanent, lifetime) low-carb diet and lost 10KG and then some. This put me on the edge of the "underweight" category as measured by BMI. (As of today I am 70KG and hovering around 18.7 BMI).
We are all different, but I am tolerating this weight level. Maybe it could go even lower, although my doctor would not be happy (he complained that if I lose any more weight, I will "disappear") and I do worry about it, a little bit.
But in some ways, weight is neither here nor there. What matters is that I brought my blood glucose sharply down, to non-diabetic levels, with the low-carb diet that was prescribed by my doctor. Eventually, if "weight too low" really begins to bother me, I could increase the fat intake while remaining low-carb.
Diabetes is a nasty, chronic disease. So I'd rather be borderline-underweight and have the disease firmly reversed, and try not to worry about the weight issue.
