In the beginning those who were fortunate enough to be born with a really strong pancreas will find it producing so much insulin, so fast, in response to all this “simple” carbohydrate in the diet, that it quite literally removes so much glucose from the blood there is not enough left to run the brain. These people get sudden bouts of weakness, lightheadedness, nervousness, irritability, poor memory, difficulty concentrating and thinking. All courtesy of a brain that does not have enough fuel to run on. As soon as they eat, the blood glucose level rises and they feel better. However, if they eat “simple” carbohydrates, they will feel terrific, but only for a short period of time, and then a little later as the insulin from their pancreas floods in, their blood sugar drops and they are in the pits again. This is what is known as hypoglycemia or low blood sugar.
