The glycemic index (GI) diet is based on the concept of the glycemic index, which ranks foods on a scale of 0 to 100 based on how much they raise your blood sugar levels. The diet was developed to help people with diabetes manage their blood sugar, but it has also been shown to result in weight loss and lower the risk of heart disease. However, the way it ranks foods has been criticised for being unreliable and failing to reflect foods' overall healthiness.

What You'll Learn
- The glycemic index (GI) assigns a number to a food based on how quickly it can raise your blood glucose levels
- Studies have shown that the low GI diet may result in weight loss, reduce blood sugar levels, and lower the risk of heart disease and type 2 diabetes
- The glycemic index diet is not a weight loss diet, but it can help people with diabetes who count carbs to manage their blood sugar
- The GI score depends on many factors including cook time, grain size, and preparation methods
- Foods on the glycemic index diet are scored on a scale of 0 to 100 based on how much they raise your blood sugar level
The glycemic index (GI) assigns a number to a food based on how quickly it can raise your blood glucose levels
High-GI foods (70 or higher) include white rice, white bread, pretzels, white bagels, white baked potatoes, crackers, and sugar-sweetened beverages. Medium-GI foods (56-69) include grapes, spaghetti, ice cream, raisins, and corn on the cob. Low-GI foods (55 and under) include oatmeal, peanuts, peas, carrots, kidney beans, hummus, skim milk, and most fruits (except those listed above and watermelon). On the diet, you try to eat more foods in the low-GI category and fewer in the high-GI group.
The glycemic index diet is not a weight-loss diet, but one study showed that people on a low-glycemic diet lost more fat than those on a high-glycemic diet with the same calories. Overall, the scientific evidence is mixed and unable to show consistent findings. While the glycemic index may guide your choice of carbs, you'll have to decide how much of them to eat.

Studies have shown that the low GI diet may result in weight loss, reduce blood sugar levels, and lower the risk of heart disease and type 2 diabetes
The glycemic index (GI) diet is based on the concept of the glycemic index, which assigns a number to a food based on how quickly it can raise your blood glucose levels. Carbohydrate-containing foods are ranked on a scale of 0 to 100 and divided into low, medium, and high-glycemic categories. High-GI foods include white rice, white bread, pretzels, white bagels, white baked potatoes, crackers, and sugar-sweetened beverages. Medium-GI foods include grapes, spaghetti, ice cream, raisins, and corn on the cob. Low-GI foods include oatmeal, peanuts, peas, carrots, kidney beans, hummus, skim milk, and most fruits. The diet recommends eating more foods in the low-GI category and fewer in the high-GI group.
However, it's important to note that the scientific evidence is mixed, and the way the GI diet ranks foods has been criticised for being unreliable and failing to reflect foods' overall healthiness. Some higher-glycemic foods are still healthy, like sweet potatoes, and some lower-glycemic foods can be high in calories, like nuts. While the GI diet may guide your choice of carbs, you'll have to decide how much of them to eat.

The glycemic index diet is not a weight loss diet, but it can help people with diabetes who count carbs to manage their blood sugar
The glycemic index (GI) diet is not a weight loss diet, but it can help people with diabetes who count carbs to manage their blood sugar. The GI diet is based on the concept of the glycemic index, which assigns a number to a food based on how quickly it can raise your blood glucose levels. These carbohydrate-containing foods are ranked on a scale of 0 to 100 and divided into low, medium, and high-glycemic categories. High-GI foods (70 or higher) include white rice, white bread, pretzels, white bagels, white baked potatoes, crackers, and sugar-sweetened beverages. Medium-GI foods (56-69) include grapes, spaghetti, ice cream, raisins, and corn on the cob. Low-GI foods (55 and under) include oatmeal, peanuts, peas, carrots, kidney beans, hummus, skim milk, and most fruits. The GI diet can help people with diabetes choose carbs wisely and manage their blood sugar levels. However, it is important to note that the GI diet doesn't cover everything you eat or should eat for a healthy diet. Some higher-glycemic foods are still healthy, like sweet potatoes, and some lower-glycemic foods can be high in calories if eaten in large quantities, like nuts. While the GI diet can guide your choice of carbs, you still need to decide how much of them to eat. Studies have shown that a low-GI diet may result in weight loss, reduce blood sugar levels, and lower the risk of heart disease and type 2 diabetes. However, the way it ranks foods has been criticised for being unreliable and failing to reflect foods' overall healthiness. Overall, the scientific evidence is mixed, and the GI diet should not be solely relied upon for weight loss or managing blood sugar levels. It is important to consult a healthcare professional for personalised advice and to ensure that any dietary changes are safe and appropriate for your individual needs.

The GI score depends on many factors including cook time, grain size, and preparation methods
The Glycemic Index (GI) diet is based on the concept of the glycemic index, which assigns a number to a food based on how quickly it can raise your blood glucose levels. Foods are ranked on a scale of 0 to 100 and divided into low, medium, and high-glycemic categories. The GI score depends on many factors, including cook time, grain size, and preparation methods.
Cooking time can affect the GI score of a food. For example, the longer a food is cooked, the more its starch molecules break down, which can raise its GI score. This is because longer cooking times can make it easier for the body to digest and absorb the carbohydrates in the food, leading to a faster rise in blood sugar levels.
Grain size can also impact the GI score. Smaller grains tend to have a higher GI score because they have a larger surface area, which makes it easier for digestive enzymes to break down the starch. This means that smaller grains can be digested and absorbed more quickly, leading to a faster rise in blood sugar levels.
Preparation methods can also affect the GI score of a food. For example, grinding or mashing a food can increase its GI score because it breaks down the starch molecules, making them more accessible to digestive enzymes. Similarly, cooking methods that involve high temperatures, such as frying or grilling, can also increase the GI score by causing the starch molecules to gelatinise and become more digestible.
The GI score of a food can also be influenced by the presence of other ingredients. For example, adding fat, protein, or acid to a meal can lower the GI score by slowing down the digestion and absorption of carbohydrates. This is because these nutrients take longer to digest, which can help to offset the rapid rise in blood sugar levels caused by high-GI foods.
Finally, individual factors can also affect the GI score of a food. For example, the ripeness of a fruit or vegetable, as well as its variety and growing conditions, can impact its GI score. Additionally, the way a food is processed by the body can vary from person to person, which means that the GI score of a particular food may not be the same for everyone.

Foods on the glycemic index diet are scored on a scale of 0 to 100 based on how much they raise your blood sugar level
The glycemic index (GI) diet is based on the concept of the glycemic index, which ranks foods based on how quickly they raise your blood glucose levels. Foods on the glycemic index diet are scored on a scale of 0 to 100, with low, medium and high-glycemic categories. The diet is particularly useful for people with diabetes who need to manage their blood sugar levels.
High-GI foods (70 or higher) include white rice, white bread, pretzels, white bagels, white baked potatoes, crackers and sugar-sweetened beverages. Medium-GI foods (56-69) include grapes, spaghetti, ice cream, raisins and corn on the cob. Low-GI foods (55 and under) include oatmeal, peanuts, peas, carrots, kidney beans, hummus, skim milk and most fruits (except those listed above and watermelon).
The diet is not specifically a weight-loss diet, but studies have shown that it may result in weight loss, as well as reducing blood sugar levels and lowering the risk of heart disease and type 2 diabetes. However, the way it ranks foods has been criticised for being unreliable and failing to reflect foods' overall healthiness. For example, some higher-glycemic foods are still healthy, like sweet potatoes, and some lower-glycemic foods can be high in calories, like nuts.
