This sudden rise of glucose level feels appetizing and lets the individual think that he is fuller. But then after some time the individual feels hungrier as the food that he has taken had fully burned and the excess glucose is stored by the body. This is converted into other forms like fats. Fats are the last one to burn to give energy so the individual carves for more food ultimately eating more and storing more fats in the body.

As the food is digested gradually so the glucose is released by proper intervals providing the supply to the energy demands. During this process the person feels much fuller and there are no carvings for more food.
