Glycemic index is a rabbit hole down which you don't want to go. First they tell you to use the glycemic index. Then they tell you, No, don't use the glycemic index, use the glycemic load. Then finally someone comes in and tells you to ignore the other two and use the insulin index.
There may be some validity to glycemic index, glycemic load and insulin index, but paying attention to calorie density is much simpler and more effective (for me at least)
