A diet based on the glycemic index, also known as the GI diet, can lead to positive weight loss results. The glycemic index diet is centered on choosing foods that steadily raise your blood sugar, rather than rapidly. Because this diet is based on controlling blood glucose levels, the GI approach is used for weight-loss as well as controlling type two diabetes. Though positive results have been reported with this type of diet, there may be drawbacks as well.
Expense
Allowable foods on the glycemic diet have the potential to be more expensive, especially if you love foods that consist mainly of carbohydrates. While carbs are allowed on the glycemic diet, you must choose breads and pastas that are whole grain. Basic white bread, rice and pasta are typically made with bleached flour, which is easier on your budget, but higher on the GI scale.
Accuracy
The glycemic index rates food individually. This rating can give you an approximation of how it will effect your blood sugar. However, since you tend to eat more than one type of food in one sitting, it can be hard to predict how the food, despite it's index rating, is going to be absorbed. Your body processes food differently depending on several factors such as the type of food, quantity, even what time of day it is when you eat. These variables can skew how the GI diet predicts your meals effect on blood sugars.
Availability
Another possible drawback of the glycemic diet is finding available low glycemic foods. The majority of foods on the market are not labeled based on their place within the glycemic index. This can make it very difficult to choose the right kind of food. Before leaving for the store, be sure you have a list of low GI items so you know what to buy.
Concern Over Fats
Some foods on the GI diet may be low on the index but still high in sugar and saturated fats such as whole milk, nuts, and sauces. Like any diet plan, consuming to much fat may put you at risk for certain health conditions including high cholesterol, heart disease and hypertension.
