What Is a High Glycemic Diet?
A high glycemic diet is one in which foods that raise blood sugar levels are eaten regularly. Foods with a high glycemic index spike blood sugar quickly after consumption, causing the release of insulin and lowering blood sugar rapidly. There is a relationship between consumption of a high glycemic diet and weight gain—a high glycemic diet is usually necessary before and after strenuous exercise, but can lead to health problems in the absence of a regular exercise routine.
