The only way to accurately find out if you are in light, medium, or deep ketosis is by using a blood ketone meter like the Precision Xtra. Ketone salts contain ketones that are most commonly bound to sodium, calcium or potassium to increase uptake. Transitioning to a very low-carb diet can cause you to crave foods that are restricted on the ketogenic diet, such as cookies, bread, pasta and bagels.
