Mice on a high glycemic index diet had 71 percent more body fat and 8 percent less lean body mass (muscle) than mice on a low glycemic index diet according to a new study from Diets contained exact same nutrients, but different glycemic index
The mice were given diets containing exactly the same nutrients except that for one group the starch had a high glycemic index, while the other group the starch had a low glycemic index.
For four months prior to the beginning of the study the animals were all kept on a diet to keep their average body weight the same.
Glycemic index risk factor for obesity, diabetes, heart disease
Glycemic index is an independent factor for obesity and increase risks of diabetes and heart disease in animals according to the authors of the study.
Low glycemic index foods reduce intake
Several studies here have found the low glycemic index foods reduce calorie intake.
Glycemic index defined
Glycemic index is a ranking of how fast a given food triggers a rise in the blood sugar level.
A more complete definition of glycemic index and glycemic load can be found here.
Glycemic index tables
Tables listing the glycemic index of numerous foods can be found here.
Practical advice: To lower glycemic index, take a fiber supplement before eating
One simple way of reducing glycemic index of a meal is to take a soluble fiber supplement such as guar gum or glucomannan prior to eating. These fibers form a gel which slows the absorption of food.
