The latest 'hot' diet to hit market is 'GI Diet' or 'Glycaemic Index' diet. Used by stars such as Kylie Minogue and Helen Porter, GI Diet was invented in 1981 by Dr David Jenkins and is actually well respected by qualified nutritionists too, so it's not just latest 'celeb fad' diet.
Dr Jenkins based his ideas on his observations into how different carb-rich foods affect human blood sugar levels in diabetics. What he found amazed him and us here at www.supadiet.com too - namely that there are some starchy foods that affect blood sugar levels dramatically, while some sugar-heavy foods actually have little effect. This is, of course, in direct contrast to all perceived medical wisdom. The culmination of Dr Jenkins' work is a scale called Glycaemic Index, ranking foods on basis of how they affect your blood sugar levels.
Starting with glucose which has a GI of 100, GI scale goes all way down to zero. By comparing how various foods raise blood sugar levels when we eat them, each food can be positioned on GI scale relative to glucose. A high GI value means food causes a fast and large rise in blood sugar levels, while a low GI value means food has only a slow, low effect on blood sugar. Foods that have low GI values are supposed to release sugar into blood slowly, over a long period, providing constant energy thru day, meaning that hunger pangs are less likely to strike. High GI value foods, in contrast, flood body with sugar fast, but effect wears off just as quickly meaning you get hungry again.
This is why a candy bar often seems such a good idea when we are starving, yet rarely satisfies. Keep that kind of snacking up, and you end up pumping far more calories into your system than you actually need, because falling blood sugar levels make you body think you are hungry again. A recipe for weight gain, in fact, as several researchers at www.supadiet.com have found to their cost!
