High, Medium and Low Glycemic Index Foods

This online glycemic index chart is in the style of the traffic light system that appears in the low glycemic index diet books by Rick Gallop. Red light foods are those you want to avoid in order to lose weight; yellow light foods are those you can eat occasionally; and green light foods are the foods that are preferred for your diet. Foods in the green zone will be digested more slowly than yellow and red zone foods so you will feel full for longer and will be able to eat less calories without feeling hungry. It is also worth noting that adding a low G.I. food to a meal will lower the glycemic index of the whole meal. You can find meals that include low GI foods in our recipe section.

Glycemic Index

Glycemic index is a measure of how quickly your body metabolises carbohydrates. Foods low in carbohydrates cannot be measured for G.I. so they are not included in this chart and are considered to have a glycemic index of zero. This does not mean you should not eat them, it is quite acceptable and beneficial to include meat and fish and other high protein foods in your diet, but try and keep fats to a minimum.
