Diets come in all forms and one that many people rely on is the low Glycemic Index Diet.

The Index is a number value or scale, from 0 to 100, that tell us how quickly the carbohydrate in a certain food will raise blood sugar in the body. The low level on the scale is 55 and below, medium index levels are between 56 and 69, and high on the index scale is 70 and above. Different carbs (carbohydrates) will convert to glucose (sugar) and enter the bloodstream at different rates, and therefore vary in how much of a blood sugar spike you experience.
This blood sugar spike is important because a sudden flood of glucose into the blood puts a demand on the pancreas to release a corresponding amount of insulin. Insulin will bring our blood sugar back to an acceptable level by transferring the glucose from the blood and into your cells where the cells use all they need for energy, with the excess being stored as fat. Excessive levels of both blood glucose and insulin have been associated with many health concerns, including obesity, type 2 diabetes, heart disease, and some cancers.
Foods with a high glycemic index rating are those that fill you up quickly, give a fast burst of energy, but then leave you feeling hungry, lethargic, sleepy, moody, and irritable a short time later when you crash from the "sugar high". These foods include white bread, pasta and white rice. These are the same foods that many nutritionist refer to as "bad carbs".
Food with a low glycemic index reading, on the other hand, fill you up, but raise blood sugar slowly and steadily, giving you a longer feeling of being full and continuous energy. These are also foods containing carbohydrates, but are considered "good carbs" as found in fruits and vegetables.
Obviously diabetics must concern themselves with these numbers for better control over their condition. However, having some familiarity with the glycemic index ratings of foods can be effective for those who are attempting to lose weight. Many physicians are recommending Glycemic Index Diets because short-term studies show that consuming foods with a low glycemic index (gi) number can be an effective approach to long term weight loss, as foods with a low gi makes you feel full longer and stay satisfied longer, thus you are less likely to overeat, and because the body is actually utilizing the amount of glucose being produced, there is no excess glucose being stored as fat.
Eating a low Glycemic Index Diet is not about avoiding carbs all together, but focusing on the more healthful carbs. Foods with low glycemic index make it possible to enjoy all foods, even those that rank high because combining these two together helps to balance out the count, with index levels in the medium range. So if you crave foods with more sugar, try eating them with foods that rank lower on the scale so that your health will not be compromised. Remember, it's the overall diet that counts, and not individual foods.
