But that won't happen, because your body will just keep making more glucose no matter what you eat.
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.)
Dial back the misinformation.
Fats are not turned into glucose before they are burned. If anything you could say that carbs are almost always metabolized like fat. The fatty acid chains break down into 2 carbon units (Acetyl co A), not 3 carbon (pyruvate) units like with carbohydrate metabolism.
Fats do travel across membranes without assistance from carbohydrates. It is true that 3 fatty acids bind with a glycerol to from a trig, but the triglycerides are broken down into free fatty acids and glycerol before crossing membranes. On the other side of the membrane a trig is reformed, but not necessarily with the same glycerol.
Your brain can survive during periods of starvation on ketones.
You eat medium chain triglycerides all the time -it’s just a medium length fatty acid found in food.
