Written by Mavis Barton

The latest 'hot' diet to hitrepparttar market isrepparttar 113087 'GI Diet' or 'Glycaemic Index' diet. Used by stars such as Kylie Minogue and Helen Porter,repparttar 113088 GI Diet was invented in 1981 by Dr David Jenkins and is actually well respected by qualified nutritionists too, so it's not justrepparttar 113089 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 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 allrepparttar 113090 perceived medical wisdom. The culmination of Dr Jenkins' work is a scale calledrepparttar 113091 Glycaemic Index, ranking foods onrepparttar 113092 basis of how they affect your blood sugar levels.

Starting with glucose which has a GI of 100,repparttar 113093 GI scale goes allrepparttar 113094 way down to zero. By comparing how various foods raise blood sugar levels when we eat them, each food can be positioned onrepparttar 113095 GI scale relative to glucose. A high GI value meansrepparttar 113096 food causes a fast and large rise in blood sugar levels, while a low GI value meansrepparttar 113097 food has only a slow, low effect on blood sugar. Foods that have low GI values are supposed to release sugar intorepparttar 113098 blood slowly, over a long period, providing constant energy thrurepparttar 113099 day, meaning that hunger pangs are less likely to strike. High GI value foods, in contrast, floodrepparttar 113100 body with sugar fast, butrepparttar 113101 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, becauserepparttar 113102 falling blood sugar levels make you body think you are hungry again. A recipe for weight gain, in fact, as several researchers at have found to their cost!
