Dieting 101
The Glycaemic Index Diet
The glycaemic index diet is based on the glycaemic index, a chart showing foods and a score representing the rapidity that the carbohydrates of the food type gets changed to sugar in the dieters blood stream. The claim is that slow acting types of food (ie those foods with a low Gi score), will keep you feeling full for longer and help you to take in less food without craving snacks all the time.
It's also extremely useful for diabetes sufferers, as the low GI types of food are useful in controlling rises in blood glucose secretion.
