A New Paradigm for Eating Foods With a Low Glycemic Impact
What is the secret of effective weight management? When a person develops type 2 diabetes, this is a critical question. Losing weight is one of the most successful ways of dealing with this disorder. This is the challenge that I faced when I diagnosed as diabetic about 15 years ago.
At first I tried low-carbohydrate dieting, but was unable to endure the severe food restrictions. Then I opted for a combination of eating foods with a lower glycemic index and a lower energy density. The glycemic index measures how rapidly carbohydrate foods are digested and metabolized into blood sugar.
A related concept is the glycemic load, which applies the glycemic index to specific serving sizes. Energy density is a measurement of calories per gram of food. By eating foods with a lower energy density, we increase the weight volume of foods for the same calorie level. Applying these principles along with regular exercise allowed me to lose nearly 80 pounds.
After a period of time, I began to wonder if the glycemic index and energy density principles could be combined into a single measuring tool. Analyzing the challenge, I developed a concept that I called “glycemic density.” It is a measurement that corresponds to the glycemic load in a gram of food. By making selections with a lower glycemic density, we increase the weight volume of foods for the same glycemic load.
Later I concluded that the concept was not quite complete. I began to chart my food using a graph that I called the “glycemic matrix.” On the horizontal axis I listed foods according to their glycemic density, and on the vertical axis I listed foods according to their glycemic index.
The foods with both a low glycemic index and a low Glycemic Density have the least glycemic impact and satisfy hunger the most. The foods with a high glycemic index and a high glycemic density have the highest glycemic impact and satisfy hunger the least. You can find more information about this concept on my web site http://www.GlycemicDensity.com.
