The Glycemic Index and Dieting:
Why should you take the glycemic index into consideration when eating food?
It's probably one of those everyday things for you. You have eaten a lot of food, are full and then suddenly one hour later you feel like you could eat more. What happened? It can hardly be a lack of calories!
It is most likely that you have consumed foods with a high glycemic index (GI).The carbohydrates have rapidly increased you blood sugar levels. Your body has released great amounts of insulin in order to normalise the blood sugar levels and to break down the blood sugar. The rapid increase of the blood sugar causes the body to exaggerate the amount of insulin released. The excess insulin lowers the blood sugar levels to such an extent that it causes hyperglycaemia. The hyperglycaemia is what causes you to feel hungry all over again.
The only way to avoid this is to eat foods with a low glycemic index (GI). The gradual and weaker increase of the blood sugar levels causes you to feel full for longer periods of time.
