Hi
@NonStop, depending on variables such as amount of insulin resistance, visceral fat, beta cell loss, liver and pancreas function, it might take a significant time to reverse diabetes using a moderate restriction. Michael Mosley (of Trust Me i'm a Doctor, The 5.2 diet and The Blood Sugar diet) advocates rapid weight loss over circa 8 to 12 weeks, supplemented thereafter with a Mediterranean diet (if it were me I would supplement with LCHF).
Rapid weight loss I would suggest offers advantages as you can see results quickly which can help with motivation. Peers will notice and comment, which enables further encouragements ; in addition other conditions such as high blood pressure, eye, circulatory, fatty liver and or kidney issues can be alleviated.
Lables such as "cured", "reversed", "remission", and "well controlled", are about definition. I am of the opinion that a "reversal" is statistical reduction of key markers (fasting blood glucose, 2 hour response after meals, and either 2 or 3 normal range HbA1c measurements in a row) to within non-diabetic ranges. I think during the lead up to the aforementioned, reductions could be classified as "reversing". I am not sure about "cured" as this is others say is down to OGTT tests or responses after a carby meal.
