According to Jason Fung, keeping blood glucose in control isn’t enough if it’s being achieved by hypoglycaemics that simply move the glucose somewhere else. They treat the immediate symptoms but not the disease, and have little or no impact on the prevention of long term complications. In fact they make the disease worse. The real treatment is to stop ingesting glucose and purge it
out of the body with fasting, not put more in and use pharmaceuticals to sweep it under the carpet.
This is the view of Jason Fung, not my own personal research, but I think he’s right. Others are free to disagree
