People lost a similar amount of weight when their carbohydrate-rich foods were replaced with high glycemic foods as compared to low glycemic foods according to a recent study from The Royal Veterinary and Agricultural University in Frederiksberg, Denmark. However, there was a 10 percent decrease in LDL cholesterol in the low glycemic food group and a tendency for total cholesterol to decrease as well which was not seen in the high glycemic food group. Weight Loss
Weight Loss: 4.2 lbs vs 2.9 lbs
Those given low glycemic foods lost an average of 4.2 pounds in two-and-a-half months versus 2.9 pounds for those given high glycemic foods. The difference was not statistically significant which means that they difference could have been due to random chance.
Replacement foods equal in calories, calorie density, fiber, protein, fat and carbohydrates
The foods given to each group to replace their carbohydrate-rich foods each contained the same amount of protein, fat, carbohydrates, calories, calorie density and dietary fiber. They only differed in glycemic index.
LDL Cholesterol decreased 10% in a low glycemic group
LDL cholesterol decreased by 10 percent in the low glycemic food group compared to the high glycemic food group.
Conclusion: Low glycemic foods may reduce risk of heart disease, but do not appear helpful with weight control
“This study does not support the contention that low-fat, [low glycemic index] diets are more beneficial than [high glycemic index] diets with regard to appetite or body-weight regulation as evaluated over 10 [weeks],” the authors concluded.
“However, it confirms previous findings of a beneficial effect of [low glycemic index] diets on risk factors for ischemic heart disease.”

No difference in body weight decrease between a low-glycemic-index and a high-glycemic-index diet but reduced ldl cholesterol after 10-wk ad libitum intake of the low-glycemic-index diet.
