Ketonix breathalyser readings interpretation


Hi all, I’m 5 weeks old old in this lifestyle and enjoying the journey and have lost a kilo week since I started. I went all in and cut my net carbs to under 15 grams. I’m hoping there’s someone out there who can help me interpret this reading from the ketonix.

I’m not sure whether I should be happy or worried since I’ve never had such a high reading before. All my google search always leads to blood ketones and I hope someone can shed some light on this. I need to understand what this means in regards to either/or ketosis and adaptation. TIA

Is it calibrated? Ie does it essentially say zero before you blow?


Yes. It’ was fully calibrated before I started. It was on Zero. This was the second reading just to make sure. The first one was 67.

Then I’d say you’re doing just fine


Ok thanks for that.

I’ve spent weeks with numbers that high during fasts. As long as you aren’t a Type 1 diabetic with extremely high blood glucose numbers too, then you are fine.


Thanks. That was actually after an unplanned fast. So perhaps you may be able to help with the best range of numbers that indicate I’m in ketosis. Thanks.
