A low-glycemic diet is one that selects foods on the basis of minimal alteration of circulating glucose levels. Glycemic index (GI) and glycemic load (GL) are measures of the effect on blood glucose level after a food containing carbohydrates is consumed. Glucose is one of the body's main sources of energy; it is the fuel used by the brain, muscles, and other organs. Glucose is set at 100, and all foods are indexed against that number. Low GI foods affect blood glucose and insulin levels less and have a slower rate of digestion and absorption.

One example of a low-glycemic diet is the Glycemic Index Diet developed by David J. Jenkins, a professor of nutrition at the University of Toronto and, from 2002 onwards, turned into a successful line of diet books by author and former president of the Heart and Stroke Foundation of Ontario, Rick Gallop. Switching from a high glycemic index diet to a low glycemic index diet is considered to be relatively easy. Switching from white bread and pastas to whole grain, from breakfast cereals to oats, bran or barley, adding more fruits and vegetables when cooking, and reducing potato consumption can all aid in lowering glycemic index. Supporting the concept of the low-glycemic diet is the research demonstrating the quality of the caloric intake is influential in weight loss.

The glycemic index is a useful aid for diabetics and other people who wish to control their blood glucose levels. A diet based on foods with low glycemic response has been associated with diabetes management, improved blood lipids (cholesterol), and reduced risk of heart disease.. Not only will foods with a low glycemic index take longer to digest (therefore prolonging satiety), they will also maintain blood glucose levels at a relatively constant state. Foods with a high glycemic index not only digest quickly, but they also can cause extreme fluctuations in blood glucose.

There are some specific factors that should be considered in foods that can indicate their glycemic index. Low glycemic foods contain fat, protein, fiber, whole grains, raw starches, legumes, vegetables, fruits and dairy products. High glycemic foods contain refined grains, refined sugars, and increased amylopectin/amylose ratio.

There are other factors that contribute to a food's glycemic index, such as plant variety, ripeness, food processing, cooking method, and the other foods served with it.

There are criticisms of the glycemic index, including its practicality because the GI applies to the food when it is consumed alone. The preparation and combination with other foods can alter its glycemic index. There is no requirement to display the glycemic index of a food product, and it is not always easy to predict the glycemic index of certain foods.

A low-glycemic diet is also questioned as a weight loss tool.

The U.S. Department of Agriculture and the U.S. Department of Health and Human Services state:

"Although total calories consumed is important for calorie balance and weight management, it is important to consider the nutrients and other healthful properties of food and beverages, as well as their calories, when selecting an eating pattern for optimal health. When choosing carbohydrates, Americans should emphasize naturally occurring carbohydrates, such as those found in whole grains, beans and peas, vegetables, and fruits, especially those high in dietary fiber, while limiting refined grains and intake of foods with added sugars. Glycemic index and glycemic load have been developed as measures of the effects of carbohydrate-containing foods and beverages on blood sugar levels. Strong evidence shows that glycemic index and/or glycemic load are not associated with body weight; thus, it is not necessary to consider these measures when selecting carbohydrate foods and beverages for weight management."
