My understanding is that acetoacetate is the āprimeā ketone, that is the direct product of ketogenesis. Unfortunately(?) acetoacetate is an unstable energy molecule that if not oxidized quickly - I suspect within minutes, but just guessing - it will spontaneously self-destruct into acetone or transform itself to β-hydroxybutyrate which is itās more stable form. Just guessing again, but I suppose β-hydroxybutyrate persists for several hours, during which it can do various healthy stuff in itās role as a hormone or signalling molecule. Eventually, β-hydroxybutyrate reverts back to acetoacetate then either to oxidize, self-destruct or transform back to β-hydroxybutyrate to repeat. The ultimate fate of every molecule of acetoacetate is either ATP or acetone. OK, some gets pissed out.
So theoretically, if I ingest exogenous β-hydroxybutyrate most remains stable for a few hours before starting to revert to acetoacetate. So the acetone Iām exhaling within a couple hours or so, should not be derived from the breakdown of acetoacetate derived from my exogenous β-hydroxybutyrate but from my current endogenous supply of acetoacetate. I suspect acetone might increase simply because the ācargoā of acetoacetate is less likely to convert into β-hydroxybutyrate - since I just ingested a substantial quantity - but instead hang around in the blood long enough for more than usual to self-destruct. If Iām lucky or fat adapted well enough, I suppose more might get oxidized as well. But generally speaking, more acetoacetate results in more acetone. We just canāt determine how much of each unfortunately.
I may be wrong, and if so Iād appreciate someone correct my understanding.
I agree. But Iām reluctant to donate blood unless I see it might serve a useful purpose. Hence, my non-invasive experiment first. As I mentioned in the OP, Iām open to the possibility of blood meter testing if the BrAce testing looks interesting.
Thanks. I think they should have run their tests for a week or more rather than only 2 days. Thatās why I intend to track/record what Iām doing for a month - until I run out of Keto Cuts. I tried using MCT oil to increase ketones both by itself and in conjunction with regular coconut oil I donāt notice that itās doing so.
