So we’ve all heard the reports that the lowly urine keto stix aka ‘pee sticks’ are only useful for the first few months for newbies. Once you’re beginning to fat adapt the wasted ketones, specifically acetoacetate, slowly and steadily decreases in the urine until the test strips show nothing. End of story. Maybe not.
I recently became aware of anecdotal reports by fat adapted or presumably fat adapted individuals also showing colour on the strips months after they should be showing nothing. What’s up with that, eh?
I’ve been in ketosis for 99% of almost the past 2 1/2 years and well enough fat adapted that I’m fully conscious and functional (most of the time ). I’ve had low breath acetone (BrAce) all day, May 30, 2019 (at or below 5ppm), even though I’ve been fairly active, at least active enough to burn some energy. For comparison I would usually be in the range of 10-20ppm. I haven’t eaten much today, so far less than 1200 calories as of 8:30pm (I’ll be eating a bit more, but there’s no way I’m going to make it to my 2700 daily target!). So for all intents I should be burning body fat and producing a solid level of BrAce. But I’m not! Go figure.
So I tested my urine. It was NOT zero! Somewhere between zero and the first colour on the chart, so somewhere between 0 and 0.5 mmol/L, probably closer to 0. Either that or I’m colour blind. So why would I be dumping acetoacetate when my liver is probably synthesizing less than usual amounts of it. Not dumping much, to be sure, but detectable. And what does it mean?
I’d like to get some data by polling forum participants. This is for long-term fat adapted people only, please. No newbies for this. To qualify I’d like you to have been in ketosis for at least 6 months (the longer the better) and fat adapted, as far as you are able to determine.
I’d like you to test your urine once or twice a day for a couple of days and report whether or not there was any colour. It doesn’t matter what colour, any colour other than the tan zero on the chart.
If you also own and use a blood testing device, I would like you to take a blood test for β-hydroxybutyrate immediately after a positive urine test. Report that as well.
If you also own and use a Ketonix breathalyzer, I would like you to take a BrAce sample immediately after a positive urine test. Report that as well. Note: Only Ketonix for this, please. Don’t report data from your cheap breathalyzer™.
Thanks in advance to one and all who participate.
