You may not have heard of this one, but the Glucose Revolution diet plan focuses on low fat and high carbohydrates and aligns itself with the GI (glycaemia index) value of foods.
Only carbohydrates appear on the GI index. Fresh meat, chicken, fish, eggs and cheese aren't included unless they have been processed in some way (for example made into sausages or chicken nuggets) involving the addition of carbohydrates ingredients - most often flour or cereal.
Eating according to the philosophy behind the Glucose Revolution diet plan means switching from high GI foods to low ones. This is because low GI foods are digested more slowly by the body, and keep blood sugar levels steady throughout the day. In addition, the steady slow digestive process reduces insulin production and this by itself encourages weight loss as insulin controls blood sugar levels. An excess promotes the body to store fat.
A healthy eating plan is at the heart of the Glucose Revolution which, once mastered can be followed indefinitely. It has been shown to reduce the risk of heart disease but it can't be assumed that the same types of foods have a similar GI rating. For instance not all breads, cereals or fruits have a low GI and how food is prepared can also be important. Cooked carrots are high on the GI index at 85 while in their raw state they score a low 35.
Traditional calorie counting fails to take into account the fact that the body doesn't absorb the same amount of calories from different foods of the same calorie value. Eating 500 calories of potatoes (a high GI food) and 500 calories of lentils (low on the GI Index) doesn't have the same results because the body absorbs 80% of the potato, but only 20% of the lentils.
While it is advised that everyone should seek out low Glycaemia foods (scoring 55 or less) such as apples and pasta and cut out high index foods such as rice, potatoes, and bananas, the weight conscious would still need to choose low-fat alternatives where possible, such as skimmed milk. Portion sizes would also still be an issue.
