My limited testing so far. I’m using the cheap eBay Greenwon with the keychain and orange backlight.
Day 1 of fast after a 3 day feast where I ate way more protein than normal:
Note: still experimenting with breathing techniques at that point, and I felt my blood ketones were on the low side of my comfort zone, which is around 1 mmol. I’m out of test strips.
Day 2, nothing but water, salt, coffee (with a little almond milk) and 2 macadamia nuts
Day 4 - broke fast previous night
I was mostly sedentary with some walking during the fast. It’s typical for me to get over 5 mmol BHB on a 3 -4 day fast.
Ate normally yesterday, but less than usual.
