Ketosis is a metabolic state in which your body burns fat for energy instead of carbohydrates. When you follow a low-carb or ketogenic diet, your intake of carbohydrates is significantly reduced, causing your body to deplete its glycogen stores. As a result, your liver starts converting fatty acids into ketones, which serve as an alternative fuel source for your brain and body. Achieving and maintaining ketosis can help with weight loss, improve energy levels, and enhance mental clarity. Monitoring your ketosis through tools like ketone test strips can help you ensure that your body is in this fat-burning state and make any necessary adjustments to your diet for optimal results.
However, for those with uncontrolled diabetes, ketosis can be dangerous if ketone levels build up too high. Elevated ketones can lead to dehydration and disrupt the chemical balance of the blood, making it acidic, which can result in a coma or even death.
How to measure ketone levels?
Measuring your body's ketone levels is the most reliable way to determine if you're in ketosis. There are three types of ketones—acetoacetate, acetone, and beta-hydroxybutyrate—which can be measured in urine, breath, and blood, respectively. Acetoacetate levels can be checked using ketone urine strips that change shades from pink to purple, with darker colors indicating higher ketone levels. While urine strips are an inexpensive and easy method to check for ketosis, they are not as accurate as other testing options.
Risks: Ketosis vs diabetic ketoacidosis
While ketosis itself isn't harmful, diabetic ketoacidosis (DKA) can occur in people with diabetes or undiagnosed diabetes. DKA happens when the blood becomes too acidic from an excess of ketones caused by a lack of insulin. This condition is life-threatening and requires urgent medical attention.
Ketone Levels:
- Negative (no ketones): Not in ketosis
- Trace (0.5 mmol/L): Mild nutritional ketosis
- Small (1.5 mmol/L): Light nutritional ketosis
- Moderate (4.0 mmol/L): Elevated ketones, often due to exercise or fasting
- Large (8.0 mmol/L): Typically from extended fasting; not sustainable long-term
- Larger (16 mmol/L): Generally due to prolonged fasting; not sustainable long-term
Note: 'mmol/L' (millimoles per liter) measures the concentration of ketones in a liquid, such as urine. In a well-formulated ketogenic diet, ketone levels usually range between 0.5 and 2 mmol/L. High ketone levels may not be suitable for everyone.
How to Use Urine Ketone Strips
Method:
1. Wash your hands.
2. Collect a urine sample in a clean container.
3. Dip the end of the ketone strip into the urine sample for a few seconds.
4. Shake off any excess liquid from the strip.
5. Wait for 15 seconds for the strip color to change.
6. Compare the strip's color to the provided color chart to determine ketone levels.
7. Discard the used strip properly.
8. Wash your hands again.
Tips for Accurate and Reliable Results:
- Compare your results with previous readings to monitor changes.
- Use a clean-catch urine sample for testing.
- Always replace the cap tightly on the strip container after each use.
- Store strips away from sunlight and moisture.
- Keep the desiccants in the container to maintain freshness.
- Avoid touching the testing area of the strip with your hands.
- Check the expiration date of the strips before use.
While urine test strips are the most common method for checking ketone levels, there are also two other devices that provide accurate measurements: blood ketone meters and breath analyzers. Blood ketone meters measure ketones directly from a blood sample, offering precise readings, while breath analyzers detect ketones by measuring acetone levels in the breath, providing a non-invasive option for monitoring.
