Glycemic index may be the way to lose weight
Results of a new animal study found that a low-glycemic- index diet can lead to weight loss, reduce body fat, and trim risk factors for diabetes and heart disease.
The glycemic index ranks carbohydrates based on their immediate effect on blood sugar levels. Carbohydrates that break down quickly during digestion have the highest glycemic index. Carbohydrates that break down slowly, releasing sugar gradually into the blood stream, have a low glycemic index.
The theory is that the rapid increase in blood sugar makes you hungry and causes you to eat more and gain weight. Meanwhile, carbs that release their sugar more slowly keep your hunger in check.
“These findings suggest that low-glycemic-index diets might help prevent and treat obesity, diabetes and heart disease,” Ludwig said.
A healthful diet, according to Ludwig, includes adequate protein, healthy fats and carbohydrates that have a low- glycemic-index - such as fruits, vegetables, nuts, whole grains and legumes.
“Low-fat diets can raise bad cholesterol and lower good cholesterol…A low-glycemic-index diet is the perfect compromise between a low-fat diet and an Atkins-type, very low carbohydrate diet,” Ludwig said.
