|Hunger is a feeling that can be brought on by one of several mechanisms. One such mechanism for initiating hunger is a low level of sugar (glucose) in the blood. When the blood glucose level falls below normal, hunger is a response. Then with eating, as the food is converted into glucose and enters our bloodstream, the feeling will usually resolve. |
How the Glycemic Index or Glycemic Load effect hunger and weight gain
High glycemic diets can cause excessive calorie intake and may result in weight gain. This may occur because when a high glycemic food or a high glycemic load meal is ingested, there is a resultant rapid rise in blood sugar. The hormone responding to this elevated blood sugar is insulin. Insulin will cause the increase in fat production and the removal of glucose from the blood stream.
Once the insulin effect has taken place, the blood sugar level drops and the feeling of hunger may occur. This hunger feeling may happen despite just eating a high caloric meal. This process may lead to excessive calorie intake and weight gain, possibly resulting in obesity.
