I'd definitely rather have an elevated morning fasted blood glucose (within reason), and low insulin, than normal blood glucose, and high insulin. And the question of what the blood glucose is over the course of the day is a very good one. If blood glucose were 120 at 8 am, and in the 80's or 90's a few hours later, over the course of the day--is that really worse than if you increased carbs at some meal, even if it did lower morning glucose levels? You might just end up having a similar increase in blood glucose, but just at a different time of day. Also, if morning blood glucose is caused by the release of cortisol early in the morning that's involved with waking up and dawn phenomenon--higher liver glycogen levels for the higher carbs taken in might just worsen things, more glycogen being there for cortisol to stimulate the release of.
