Glycemic Index of Carbs & Fat Loss??

Glycemic Index of carbs made no difference in weight loss:

The glycemic index has been proposed as a useful
tool in many areas of health. 

Low-GI foods have been recommended for better weight loss, increased satiety, and increased blood glucose control. 

Higher protein intake during weight loss has been associated with preservation of fat- free mass and of energy expenditure.

STUDY

“neither low-GI relative to high-GI diets nor moderate-carbohydrate relative to high-carbohydrate diets
showed differences with respect to effects on changes in body composition or resting metabolism during weight loss when confounding dietary factors were tightly con- trolled in a study providing all food for 22 weeks, and individual variability in metabolic adaptation following weight loss did not predict weight regain over 12 months.”

An over-reliance on the glycemic index may distract from the other factors that promote health. With weight loss in particular, energy expenditure will adapt to changes in your weight, but the results of this and other studies indicate that once weight has stabilized these metabolic adaptations appear to be sustained, and that GI is unlikely to have any effect on these changes.
