Dieting 101
The Glycaemic Index Diet
The glycaemic index weight loss regime is based around the glycaemic index, a list of food types and a score illustrating the rapidity with which the carbohydrates in the food type gets transformed to glucose in the dieters bloodstream. The theory is that long-acting foods (ie those foods with a low Gi number), will keep you feeling full for longer and help you to eat less food without feeling you are always hungry.
It's also extremely useful for diabetics, as the low GI types of food are beneficial in controlling surges in glucose amount.
