Dive Deeper: Ketones

Ketones in urine can provide valuable insights into your metabolic state and overall health. While ketosis is commonly associated with ketogenic diets, it’s essential to understand the various factors that can influence ketone production and the potential health implications. Let’s dive deeper into the details!

Testing Ketones and Their Significance

Ketones are produced by the liver when the body doesn’t have enough glucose for energy and starts breaking down stored fats. Testing for ketones in urine provides valuable insights into the body’s metabolic state and can be particularly relevant in the following scenarios:

  • Ketogenic Diets
    Ketone testing is commonly used by individuals following a ketogenic diet, a low-carbohydrate, high-fat eating plan. This dietary approach aims to induce and maintain a state of ketosis, where the body primarily relies on ketones for fuel instead of glucose.
  • Diabetes Management
    Ketone testing is also essential for people with diabetes, especially those with type 1 diabetes. It helps monitor for a dangerous condition called diabetic ketoacidosis (DKA), which can occur when there is a shortage of insulin and high levels of ketones build up in the blood.
  • Fasting or Starvation
    During periods of fasting or starvation, the body begins to break down fats for energy, leading to increased ketone production. Ketone testing can help assess the body’s adaptation to fasting or identify potential complications.
  • High-intensity Exercise
    Intense physical activity can deplete glycogen stores and promote ketone production. Testing for ketones can provide insights into the body’s metabolic response to exercise and help optimize performance and recovery.

By testing ketone levels in urine, individuals can monitor their body’s adaptation to specific dietary patterns, manage diabetes effectively, and ensure the safe implementation of fasting or intense exercise regimens.

Optimal Results

Test Result: Optimal / Trace


Ketone Value:  0 – 0.5 mmol/L


Wellness Score: 10/10 or 9/10


Wellness Label: Optimal

What this means for health


A urinary ketone level that is trace or optimal generally indicates that the body is efficiently using ketones as an energy source, which is common during periods of fasting or a ketogenic diet. This finding is typically not a cause for concern and may be associated with weight loss or dietary changes. Still, it should be interpreted regarding an individual’s overall health and dietary choices.

Signs and symptoms


In the context of trace or optimal urinary ketone levels, individuals often do not experience specific signs or symptoms. Ketosis, reflected in urinary ketone levels, is typically a physiological response to dietary or metabolic changes and doesn’t necessarily produce noticeable symptoms when ketones are within the normal or optimal range.

Factors that could interfere


Factors that can interfere with the accuracy of urinary ketone level readings include dietary choices, such as low-carb or ketogenic diets, fasting, and strenuous exercise, which may increase ketone production. On the other hand, factors like increased carbohydrate intake, certain medications, and underlying medical conditions can reduce or eliminate detectable ketones in urine, potentially leading to false negative readings.

Moderate Result

Test Result: Moderate


Ketone Value: 1.5 mmol/L


Wellness Score: 7/10


Wellness Label: Moderate

What this means for health


A moderate urinary ketone level of 1.5 mmol/L may indicate a state of ketosis, often associated with dietary changes, such as a ketogenic diet, fasting, or low-carb eating. While moderate ketosis can be a normal and expected response to certain dietary practices, it should be considered in the context of overall health and individual health goals, and consulting a healthcare provider for guidance is advisable, mainly if ketosis is unintentional or prolonged.

Signs and symptoms


In the context of moderate urinary ketone levels, individuals may not necessarily experience specific signs or symptoms, as ketosis can be a physiological response to dietary or metabolic changes. However, some people may notice increased urination, changes in breath odor (often described as “fruity”), and potential weight loss, but these effects can vary among individuals.

Factors that could interfere


Factors that can interfere with the accuracy of urinary ketone level readings include dietary choices, exercise, fasting, and certain medications or supplements, which can increase ketone production. Conversely, increased carbohydrate intake, certain medications, and underlying health conditions can reduce or eliminate detectable ketones in urine, potentially leading to false negative readings.

Moderate Result

Test Result: Moderate


Ketone Value: 4 mmol/L


Wellness Score: 5/10


Wellness Label: Moderate

What this means for health


A urinary ketone level of 4 mmol/L in the moderate range suggests a state of ketosis, often associated with dietary practices like a ketogenic diet or fasting. While moderate ketosis can be a normal response to such diets, it should be considered in the context of overall health and individual health goals, particularly if it’s a prolonged or unintended condition, and consulting a healthcare provider for guidance is advisable.

Signs and symptoms


Moderate urinary ketone levels may not necessarily produce specific signs or symptoms, as they often result from dietary or metabolic changes. However, some individuals may experience increased urination, changes in breath odor (often described as “fruity”), potential weight loss, and increased energy levels. Still, these effects can vary from person to person.

Factors that could interfere


Several factors can interfere with the accuracy of urinary ketone level readings, including dietary choices (such as ketogenic diets, fasting, or low-carb eating), exercise, and certain medications or supplements that affect ketone production. Conversely, increased carbohydrate intake, certain medications, and underlying medical conditions can reduce or eliminate detectable ketones in urine, potentially leading to false negative readings.

Low Result

Test Result: High


Ketone Value: 8 mmol/L


Wellness Score: 3/10


Wellness Label: Low

What this means for health


A high urinary ketone level of 8 mmol/L suggests a significant state of ketosis, typically associated with conditions like diabetic ketoacidosis, which can be a medical emergency and indicate a severe imbalance in the body’s metabolism. It’s crucial to seek immediate medical attention when urinary ketone levels are this high, as it can have serious implications for overall health and requires prompt intervention and treatment.

Signs and symptoms


Symptoms may include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, rapid breathing, confusion, and in severe cases, loss of consciousness. This condition is a critical medical emergency, and immediate medical attention is essential to address the condition and prevent potentially life-threatening complications.

Factors that could interfere


Factors that can interfere with the accuracy of urinary ketone level readings include dietary choices, exercise, fasting, and certain medications or supplements that increase ketone production. Conversely, conditions that affect the body’s metabolism, such as uncontrolled diabetes or certain medications, can lead to extremely high ketone levels in urine, which may not necessarily reflect dietary or lifestyle choices.

Low Result

Test Result: High


Ketone Value: 16 mmol/L


Wellness Score: 1/10


Wellness Label: Low

What this means for health


A high urinary ketone level of 16 mmol/L indicates an extreme state of ketosis, often associated with severe metabolic imbalances, potentially signaling a life-threatening condition such as diabetic ketoacidosis. This condition is a medical emergency, and immediate intervention by healthcare professionals is critical to address the underlying issues and prevent serious health complications.
