I think that although the foods are very similar, there are key differences between the Atkins diet and the ketogenic diet.
First, with the Atkins diet there is no fluid or calorie restriction. Also, although fats are strongly encouraged, there are no restrictions on proteins. In addition, foods are not weighed and measured, but carbohydrate counts are monitored by patients and parents. It is started outside of the hospital, without a fast, as well. Lastly, foods can be eaten more freely in restaurants and outside the home, and families can do it as well!!
