>It was actually eliminating carbs from the diet. Yes, in the past, keto diet was the main (and the only) way to treat diabetes.

Except it didn't work. People died. Meanwhile, today, we have a very good understanding about the secondary diseases, long-term damages, and how to prevent those with therapy. And a keto diet is no part of that.

Edit:

>It is true that EXCESS protein will be converted to sugars. As long as you limit your protein intake it will be used exclusively for housekeeping. That's why keto diet is not only carb elimination, it is carb elimination WHILE restricting protein to about 30% of your calorie intake.

While excess protein is indeed converted that way, it will also happen to small amounts of "non-excess" protein. Protein in your body is in a constant flux. Your muscles are not static but undergo constant breakdown and build-up. While gluconeogenesis can be strongly reduced with dietary restrictions, it cannot be completely stopped. In fact, an important inhibitor to gluconeogenesis is insulin and thus, for a healthy person, consumption of carbohydrates.
