Apologies if this is the wrong sub-forum or if this is a redundant topic.
I started a ketogenic diet in the new year and have been practicing intermittent fasting as well (16:8 for now.)
I bought some Ketone test strips to check my urine to see where I was in terms of getting into ketosis. Sure enough after a few days of practicing a high fat low carb diet my ketones levels went up.
But I’ve noticed lately that my ketone levels seem to be going down in the morning after drinking only black coffee (three cups, I’m an addict) and a glass of water with a tablespoon of apple cider vinegar.
This morning, for instance, I tested when I first woke up around 6:30 AM. I had a dark reading on the test strip (8.0 on the scale). After drinking coffee and ACV and testing again around 8:30 I had much lower results.
Am I being paranoid testing too much/overthinking it? Could it just be a fluctuation in the results from an inconsistent testing method? Is it possible that too much coffee/caffeine or ACV could be throwing me out of ketosis or inadvertently ending my fast prematurely?
Any and all advice is appreciated.
