Are you In Ketosis?
I have found measuring give me a better handle on how my body reacts to different carb loads, how much wiggle room I have to stay in nutritional ketosis. I like testing for Ketosis, it gives me confidence that I am reaching and staying in a nutritional state of ketosis.
The First Method (peeing on a Stick) Are you in Ketosis?
Many start this keto journey by peeing on a stick. In the first two weeks-Feeling excited and proud to see it turn deep purple. But as your body gets more efficient in a few weeks, your body will be more efficient and fat adapted. This will drastically reduce the number of ketones wasted in your pee. This change of efficiency makes the pee test less effective.
How I Measure (this will help you)
Jonathan Savage of fellrnr.com did a BHOB blood test correlation to Ketonix and cheap breathalyzers; he concluded that cheap breathalyzers actually correlate better to blood levels than Ketonix. I am exceedingly grateful to the super serious experimenters like him that have done cheap breathalyzer correlations and have generously shared the results.)
Measure regularly between 0.02%-0.04% BAC which would be mild nutritional ketosis correlating to 0.7mM to 1.0mM range according to this spreadsheet and also brown fat’s chart. 0.5 to 3.0 mM. is the official definition of nutritional ketosis.
The Conversion Cart (Are you in Ketosis)
The forums indicate anywhere between 0.01% to 0.05% BAC is decent ketosis.
0.01 BAC% = 0.26 ppm = ketonix 28 : blue:
0.02 BAC% = 0.52 ppm = ketonix 40 : blue just shy of green:
0.03 BAC% = 0.78 ppm = ketonix 47 : marginally green:
0.04 BAC% = 1.04 ppm = ketonix 50 : green:
0.05 BAC% = 1.30 ppm = ketonix 53 : green
Now I measure my breath once in the morning and a few more times during the day. Eating normally healthy but higher carb vegetables like onions show little or no impact on my numbers so I can push my carby veggie further.
