I have been studying diabetes mellitus lately and have a pretty good understanding of it so far. There is one thing that I am curious about and I wonder if I could get some help with this?
In the absence of carbs the body breaks down fats and protein for fuel. Part of the fuel that is used is ketones. In the case of ketoacidosis in a diabetic the body is not using the glucose available in the blood, so the body produces more glucose, as well as ketones from fatty acid oxidation. The ketones as well as the glucose can’t be used, so the pH of the blood is lowered because of the ketones. Normally when the body uses ketones for fuel it regenerates bi-carb, thus restoring the acid-base balance.
Even though ketones may not stimulate insulin secretion, is insulin still needed by cells to absorb ketones so ketones can be used as an energy source? From what I have read I think yes, but this was inferred and not stated outright.
