Does anyone know how long after a meal you will be thrown out of ketosis if that meal contained too many carbs? I'm trying to pinpoint problems in my diet and am looking to try to measure things according to my ketostix. I was wondering if there is a way to do this. I took my reading this morning and I was moderate, later on a trace and still later negative. A few hours later I was back to moderate. I'm trying to see exactly what this is reflecting. Is it possible to go in and out of ketosis all day or can I really use the ketostix to find a problem in my diet? Thanks.
