The Glycaemic Index Diet
The glycaemic index diet is reliant on the gi (or glycaemic index), a chart showing types of food and an indicator of the rapidity with which the carbs of the food gets transformed to sugar in the dieters blood stream. The theory is that long-acting food types (ie those with a low Gi number), keep you satisfied for a longer period of time and mean that you can consume fewer food without starving yourself.
It's also especially beneficial for diabetes sufferers, as the low GI foods are beneficial in preventing surges in blood sugar amount.
