A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet.
Fat-adapted low carbers may not register ketones after being in ketosis for longer periods of time. These low carbers use ketones more efficiently and levels may not be detectable in the urine, even though they are in ketosis. Play it safe, rely on your eating habits and use keto sticks to âcheck in.â.
