The Glycaemic Index Diet
The glycaemic index diet is reliant on the gi (or glycaemic index), a list of foods and a score illustrating the ease with which the carbohydrates of the food type gets transformed to sugar in your bloodstream. The claim is that slow acting types of food (ie those food types with a low Glycaemic index score), keep you feeling full longer and help you to take in fewer food without starving yourself.
It's also extremely good for diabetics, as the low GI types of food are useful in controlling increases in blood glucose levels.
