TT, I’m aware that those sugars preferentially refill liver glycogen and that blood sugar is maintained by liver glycogen. At least, the fructose component of the previously mentioned sugars. (I knew the biochem degree would come in handy some time hehe)
However, sugars with a low II, at least from my consulting experience, do not cause as much sugar cravings and blood sugar fluctuations as those with a high II. Therefore, things like straight fructose do not cause wild blood sugar fluctuations. It’s more the certain starches(and this can include starches) that behave like more like glucose, cause the the real carb cravings.
For example, if you followed a calorie controlled diet, but used high GI carbs like rice cakes, potatoes, etc., you’d notice how much more hungry you are as opposed to the same diet with low GI/II carb choices like oatmeal and vegetables.
