Hello I am attempting the ketogenic diet I have a Percision xtra blood meter with Keytone strips what I would like to know is where does the Keytone meter start do you start at zero and you’re trying to move your ketones up or do you start high and you and trying to move your ketones down to 1.5 to 3 ketones right now my meter says 0.1 ketones and 0.2 ketones what do these readings say about where I’m at I’ve been on the Ketogenic diet for 14 days now keeping my carbs below 20 grams and my fat and protein in check as well.
