Foods high on the glycemic index promote short-term fullness due to a lack of nutrients and therefore feeling hungry after just an hour. Foods high on the glycemic index are also known to cause a rapid spike in blood glucose levels. Rapid absorption of glucose after meals leads to both hormonal and metabolic changes that promote excessive food intake
