The three basic types of diets which are currently being prescribed for diabetics are

* A moderately low-carbohydrate diet which restricts mainly simple sugars and alcohol, for those who have high blood levels of triglycerides (Type IV Hyperlipo-proteinemia),
* The most commonly used diabetic diet which has from 45 to 55% of its calories supplied by carbohydrate, and
* A recently tested high-carbohydrate, low-fat diet for people who have high blood levels of cholesterol and/or other fats (Type II and other types of Hyperlipo-proteinemia).
