Keto Clarity recommended doing it with a breath analyzer, which is about as good as blood strip testing, but vastly cheaper. SO I went to Amazon and got one. It just came in.
I blew at 2.70, which I was pleasantly surprised at. Well into proper nutritional ketosis, even toward the top end. More than 3.0 isn't really ideal. You supposedly start to get into starvation ketosis. Which I don't know much about yet, and imagine must be stimulated by fasting, so I doubt it's that dangerous for most people.
Which brand/model analyzer did you get? Doesn’t seem to be a lot of reviews on ones I looked at.
