Very good answers above by nutritional experts, thank you.
It turns out low-carbohydrate is another option (1) to reduce glycemic excursion. There are some evidence that low-carbohydrate diet can lead to good glycemic control (2-3).
In my experience, with the right type of anti-diabetic pharmacotherapy, low-carbohydrate diet works well in addition to achieve composite outcome of weightloss, stable glycemic profile and minimal hypoglycemic risk.
