The Next big Diet?

(Ivanhoe Newswire) -- In the latest research on the battle of the bulge, a new animal study provides evidence that a low-glycemic index diet can lead to weight loss, reduced body fat, and reduction in risk factors of diabetes and cardiovascular disease.

In low-GI foods, carbohydrates are low in sugar or release sugar slowly. Unlike the popular Atkins diet, which aims to minimize carb intake, the low-GI diet makes distinctions among carbs.

High-GI foods, which include white bread, refined breakfast cereals and concentrated sugars, are rapidly digested and raise blood glucose and insulin to high levels. Carbs that release sugar more slowly include whole grains, most fruits, vegetables and nuts.

Results of the study show rats eating a high-GI diet had 71-percent more body fat and 8-percent less lean body mass than rats in the low-GI group, despite very similar body weight.

The fat in the high-GI group of rats was concentrated in the rear area in an apple shape instead of a pear shape. According to researchers, having an apple shape is a known risk factor for cardiovascular disease in humans. The high-GI group also had blood triglyceride levels nearly three times that of the low-GI group, another risk factor for cardiovascular disease.

Results also show the high-GI group of rats had significantly greater increases in blood glucose and insulin levels and far more abnormalities in the pancreatic islet cells that make insulin. All of these changes occur in diabetes.

Even after the two diet groups switched to the alternate diet for another three weeks, the rats that switched from low- to high-GI diets showed greater increases in blood glucose and insulin than rats switched from high- to low-GI diets.

Many studies, including small human studies, have revealed low-GI diets are beneficial, but the observed benefits may have possibly come from other aspects of the subjects’ diets, such as fiber or overall caloric intake. Children’s Hospital Boston is now recruiting adults for a large-scale, 18-month study of the low-GI diet.
