Are Keto Blood Meters Necessary to Do the Keto Diet?

We must monitor what we eat, schedule meals, exercise, and track our levels of ketones to make sure we are under the state of ketosis.

In the ketogenic diet, you might think that all you have to do is eat food high in fats and reduce carbohydrates intake. This is partly true. But going through the keto diet takes work and effort. We must monitor what we eat, schedule meals, exercise, and track our levels of ketones to make sure we are under the state of ketosis. This is why keto blood meters come handy. They allow us to measure our ketone levels and overall help us achieve our goals in the ketogenic diet program.

Let us explore more about keto blood meters in the article.

Ketone Meters

These are special tools of measurement that provides a specific number of the level of millimoles per liter inside the body. Ketone meters have three different types and these are:

Blood Ketone Meters

This device is used to measure the level of ketones in the blood, particularly the beta-hydroxybutyric acid or BHB. As the main ketone body, BHB exhibits a high concentration ketone level found in the blood compared to acetoacetate and acetone. Its presence outside the cell gives it a higher accuracy level and is easier to measure.

Breath Ketone Meters

This device is used to measure ketones from the breath, mainly the acetone. The acetone ketones are actual signs of fat used as energy fuel in ketosis. This is a substance that is colorless in nature, dissolves other liquids and gases, and the most volatile of the ketones.

Ketone Strips

This device is used to measure ketones released from urine, primarily acetoacetate. Usually called urine strips, these are affordable and easy to use if you’re in the state of ketosis. It measures acetoacetate through urination as it changes color to indicate ketone levels.

Keto Blood Meters

Measuring ketone levels is more accurate using keto blood meters as the ketones found from the breath and urine are inconsistent. Acetoacetate is the primary ketone used in ketone strips. It turns itself to beta-hydroxybutyric acid as a lot of acetoacetates are converted to BHB to transport energy from the liver, to other body tissues and the brain. On the other hand, Acetone is a byproduct of Acetoacetate which dissolves quickly, if not used. It goes out through the breath or through urine making it inconsistent in nature and the least abundant ketone produced in small amounts.

BHB or beta-hydroxybutyric is the easiest ketone to measure and the most accurate ketone to measure in the blood. This is because it is the most prevalent and has a higher concentration of ketones.

Keto blood meter is an effective tool that helps to improve one’s diet by monitoring their BHB through the blood. These devices are specifically designed for users to do the ketogenic assessment easily on a daily basis.

Steps on Using Keto Blood Meters

  1. Wash hands and keep it dry. It is important when doing a test, may it be minor or major, that cleanliness is always a priority. Keeping a clean pair of hands will allow you to prevent infections from happening.
  2. Load the lancet with the needle following instructions. The lancet is the device to use in pricking your finger with the use of the needle. You should follow directions associated with the device on how to properly use it to avoid accidents.
  3. Place the ketone strip into the blood ketone meter. The ketone strip is the placeholder for the blood and it is the place where the device will calculate the level of ketones that you have.
  4. Prick the tip of your finger using the lancet. Follow the directions and properly prick the finger using the lancet. Make sure to have alcohol and cotton to cure immediately the finger used.
  5. Wait for the device to calculate and produce the ketone levels. After pricking your finger and the drops of blood are already on the strip for calculation, wait for the device to calculate the ketone levels. Make sure you’re in an open area so blood stains won’t scatter in the area if in case blood drips from the device or your fingers.
  6. Discard the strip and lancet needle as advised in the directions: After the procedure, carefully discard the strip and needle from the lancet making sure that there’s an immediate box, paper, or plastic where these apparatus must be thrown.
  7. Properly dispose of the strip and lancet needle. After discarding the strip and needle, putting it inside a box, plastic, or paper; dispose of the materials properly by dropping it in a hazardous trash bin.


It is important to track your ketone levels accurately as much as you monitor your food and activities. This allows you to follow your development and process in doing the ketogenic diet and ensure that you are under ketosis. The goal is to eat high fat, moderate protein, low carbohydrates and using a ketone meter, the keto blood meter, is the best way to test and monitor ketosis whether you are already doing keto diet or you’re starting the ketogenic eating plan.
