Assuming this model pans out, it will be interesting if insulinogenic food indexes like below will be used to monitor insulin-releasing responses of different foods as a means to limit weight gain/maximize fat loss? Then again, I'm not sure because other studies suggest total calories is king. Nutritional research is very confusing:
An insulin index of foods:the insulin demand generated by 1000-kJ portions of common foods.
Beyond Glycemic Index: New food insulin index
