A researchers input and presentation of what a ketogenic diet really is.

It is somewhat common for someone to buy some "keto" bars or other "keto" food and say they are on a keto diet. Yet they may be a long ways from ketosis and not really on a nutritional ketogenic diet at all. Some people use "low carb" and "keto" as interchangeable when they are not. A ketogenic diet has to be low carbohydrate but a low carbohydrate diet is not necessarily a ketogenic diet.

There are many variations to the ketogenic diet for specific purposes. For example to control seizures it is a very strict diet.

Researcher Dom DAugostino goes into detail of the ketogenic diet and what the different purposes are.
