It seems that the medical establishment still does not feel comfortable with suggesting low carb diets for people with heart disease. It seems that they are afraid of something or another.

This article I’ve linked to below goes through many of the different types of diets that could be called loosely low carb and covers many of the relevant points and studies in quite a comprehensive way.
