I don't know about it. I was having keto diet for a long time before they start talking about it. I was having problems with my pancreas loading insulin in my blood and was fighting hypoglycemia. My endocrinologist put me into diet without any sugar or carbs for 6 months. He saved my life. Sugar is also very toxic because used by cancer cells. Sugar makes our body acidic and allow cancer cells to grow faster. They die in alkaline environment. PH more than 7.
