A Primer on Glycemic Index and Weight Loss

Our bodies feel really drained and weak whenever we experience a dip in our blood sugar levels. This is what is known as a sugar crash.

Carbs and other viands are rated based on how they affect our blood sugar levels. The rating given is known as the glycemic index or GI.

The reactionary increase in a person's blood sugar is known as the glycemic response. There are many factors that affect this, including the type of food that is eaten as well as its preparation technique.

The glycemic response is what you call the momentary increase in the level of a person's blood sugar as an effect of eating carbohydrates. Various carbs however produce different effects on these levels, depending on how they are prepared and the kind of carbs consumed.

After the food is measured and compared with a control, it is given a rating that ranges from one to one hundred. According to the glycemic index chart, foods that rate between seventy to one hundred, such as pretzels, are high glycemic index foods. Those that rate between fifty-six to sixty-nine, such as fruit cocktail, are moderate glycemic index foods and those that rate between one to fifty-five, such as broccoli, are low glycemic foods.

Low glycemic foods have the beneficial effect of digesting the food in a gradual manner, thus insulin in the body is also released gradually. Because of the slow rise in blood sugar levels, the sensation of fullness is protracted as well. This is how eating low GI foods make you lose weight, because you ultimately eat less.

Researchers assumed in the 1980?s that the human body absorbed and digested simple sugars quickly, producing rapid increases in blood glucose level leading to the assumption to avoid sugar. But now scientists understand that simple sugars don't cause the blood glucose to rise any more rapidly then some complex carbohydrates do. But, simple sugars are still empty calories and should still be minimized. With regular exercise, little saturated or trans fat, and a high-fiber diet the glycemic index helps keep the average person at a healthy weight.
