But dude, glycogen is changed to glucose before being used by the cells for energy. So is fat, for that matter. Fat can't even move through the body or enter cell membranes unless it is "accompanied" by sugars in the form of triglycerides. No matter how much you avoid sugar and carbs, your body will be full of them. Your brain would die in about 3 minutes if there was no glucose in your bloodstream. But that won't happen, because your body will just keep making more glucose no matter what you eat.
Metabolism and respiration (that is, changing fats and starches to glucose that can be used by the cells) take time and energy of their own. This is why athletes and others doing significant work prefer to have some sugars on board--they can be used more quickly by the cells, and with little additional expenditure of energy.
As for insulin overload, the research I've been reading suggests that exercise is more effective than diet changes for dealing with that problem. Of course insulin overload isn't even a problem at all for non-thpe 2 diabetics who are eating a "healthful" normal diet and exercising.
The human body evolved to eat FOOD, not letters of the alphabet like M, C, or T. I don't even know what MCTs are, but I'm pretty sure I don't need them. (I could be wrong on that, of course, but I would be very surprised.)
