A great way to know if your keto diet is working is to test your ketone levels. There are three types of ketones: acetone, beta-hydroxybutyrate, and acetoacetate. You can measure these ketones in your blood, breath, or urine. One of the most common ways to test your ketone levels is to check the acetone in your breath. Using this method is a reliable way of observing ketosis in your keto diet. The Ketonix ketone analyzer is the ketone meter for checking acetone in the breath. There is also the blood ketone meter. For this procedure, a small drop of your blood will go on a strip. It gets inserted into the meter that checks your beta-hydroxybutyrate levels. This is another secure yet expensive way of measuring ketosis. The final one is measuring a person’s acetoacetate in the urine. You dip ketone urine strips into your urine. If it turns a darker shade, it means your ketone levels are high. This ketone-checking solution is one of the most affordable, yet unreliable, ketone checkers.
