The Glycemic Index tells us how quickly a food that you eat raises your blood sugar, and therefore causes a surge in insulin release from your pancreas. Insulin is what tells our bodies to store the extra calories as fat.
Foods with a low glycemic index don't cause such a huge rise in blood sugar, thereby limiting insulin release and limits storing calories as fat.
Further, foods with a high glycemic index will cause you to feel extremely hungry later on. In about 3-4 hours you will start to feel extremely hungry and want to eat anything and everything in sight. Why?
If you eat a large, high glycemic index food now, like beer or white bread, your blood sugar will rise to very high levels, very quickly. This causes a subsequent rise in the amount of insulin your pancreas releases. Insulin lasts longer in your blood stream and your sugar will eventually fall to lower levels than your baseline. This lower sugar (hypoglycemia) will cause your body to go into distress mode and it will make you feel very hungry. You will have to satisfy this craving and will mostly likely reach for something very sweet that has a high glycemic index. This starts the viscious cycle all over again.
We have to try and avoid this situation by eating foods that have a low glycemic index. Take a look at the charts and tables on this page and the following pages for a look at which foods in each category have the lowest and highest glycemic index.
You will notice that beer (maltose) is the worst of all, while most vegetables are very low. Foods with a GI (Glycemic Index) lower than 55 are considered Low. Foods with a GI of 55-70 are considered Medium. Foods with a GI over 70 are considered High.
