Hardly a week goes by without a new weight-loss craze hitting the headlines. From pills and detox programs to prepackaged meals, it's no wonder dieters can become confused. But there's one diet that has been helping people to successfully lose weight for years. It's backed by sound scientific research, it can be followed by eating everyday foods and all the information you need to follow it is free.
The low-GI diet was based on research that shows that some carbohydrates have a different effect on blood glucose levels than others. While some flow into the bloodstream quickly, causing glucose to spike, others trickle in slowly, keeping it low. Based on this research, the glycaemic index, or GI, was established about 25 years ago. It's a scale that ranks foods from zero to 100 based on their effect on the body's blood glucose, but how does it relate to our weight?
Your body performs best when blood glucose is kept relatively constant. If blood glucose drops too low, you are left fatigued and looking for your next food fix. But if it goes too high, the pancreas secretes more insulin. This brings the level of glucose down, but primarily by converting the excess glucose into stored fat.
