Ketone bodies are produced by the liver and are used as an alternative energy source for the body when there is a shortage of carbohydrates or glucose. This process, known as ketogenesis, occurs when the body breaks down fatty acids and ketogenic amino acids. Ketone bodies are particularly important for supplying energy to the brain, heart, and skeletal muscles. A diet that is low in carbohydrates and calories can lead to an increase in ketone formation as the body breaks down fats for energy instead of glucose. This can be seen in diets such as the keto diet, which is a popular weight-loss strategy, but it is important to consult a healthcare provider before starting such a diet as it can cause major changes to the body.

What You'll Learn
Ketone bodies
During periods of caloric restriction, such as low food intake (fasting), carbohydrate-restrictive diets, starvation, or prolonged intense exercise, the liver breaks down fatty acids to produce ketone bodies. These ketone bodies are released into the bloodstream, providing an alternative energy source for the body. The process of ketone body production is called ketogenesis, which occurs primarily in the mitochondria of liver cells.
In a state of ketosis, ketone body production is increased due to decreased carbohydrate availability or increased fatty acid levels. Ketosis can be induced by following a low-carbohydrate or keto diet, which involves reducing carbohydrate intake and increasing fat consumption. However, it is important to consult a healthcare provider before starting such diets as they can cause significant changes to the body and may not be suitable for everyone.
High levels of ketone bodies in the blood can lead to a condition called ketoacidosis, which is particularly associated with diabetes. In diabetic ketoacidosis (DKA), high levels of ketones are produced due to low insulin levels and high levels of counterregulatory hormones. DKA is a potentially fatal complication that requires immediate medical attention.

Ketosis
During ketosis, the liver releases ketones into the bloodstream, providing energy for the body's tissues. The three main types of ketone bodies are acetone, acetoacetate, and beta-hydroxybutyrate. These ketones are water-soluble and can cross the blood-brain barrier, making them available as fuel for the central nervous system. This is particularly important for the brain, which usually relies on glucose for energy. However, if too many ketones accumulate in the blood, it can lead to a dangerous condition called ketoacidosis, especially in diabetic patients.
To monitor ketone levels, individuals can use urine tests or blood tests, which are available at pharmacies or online. Urine tests use dip-and-read strips that change colour based on ketone levels, while blood tests typically involve a finger prick to obtain a blood sample. Breathalyzers for detecting ketone levels are also available, but this technology is still new and may not be reliable. Maintaining safe ketone levels is crucial, especially for individuals at risk of ketoacidosis.
In summary, ketosis is a metabolic state characterized by the body's use of ketones as its primary energy source. It is typically induced by a low-carbohydrate diet, leading to increased ketone production by the liver. While ketosis can be beneficial, careful monitoring of ketone levels is essential to prevent potential health risks associated with high ketone accumulation, particularly for individuals with diabetes.

Ketogenic diets
Ketone bodies are acids produced by the liver during periods of caloric restriction or low carbohydrate intake. They are formed through the breakdown of fatty acids, specifically the oxidation of acetyl-CoA, which is a byproduct of fatty acid oxidation. The three main ketone bodies are acetone, acetoacetate, and beta-hydroxybutyrate. These ketone bodies are released into the bloodstream and used by other tissues, such as the brain and heart, as fuel. The brain particularly benefits from ketone bodies as they can cross the blood-brain barrier, providing an alternative energy source when glucose is scarce.
The ketogenic diet has gained popularity due to its potential health benefits, such as weight loss and improved energy levels. Additionally, it has been suggested that a ketogenic diet may help treat epilepsy in children and provide neuroprotective effects against ischemic stroke. However, it is important to note that the keto diet is very restrictive and can be challenging to maintain over extended periods. Furthermore, it can lead to a build-up of ketones in the blood, known as ketoacidosis, which is particularly dangerous for diabetic individuals.
Monitoring ketone levels is crucial, especially for those at risk of ketoacidosis. Urine tests and blood tests can be used to check ketone levels, with blood tests providing a more accurate and current reading. Breathalyzers for detecting ketone levels are also available, but this technology is still new and may not be reliable. Maintaining a balanced diet and consulting with a healthcare provider before starting a ketogenic diet are essential to ensure safety and effectiveness.
In summary, a ketogenic diet, characterized by low carbohydrate and high-fat intake, can lead to ketone formation through the process of ketosis. While this diet may offer certain health benefits, it also carries risks, particularly for individuals with diabetes or other metabolic conditions. Proper monitoring and consultation with a healthcare provider are necessary to maintain a safe and effective ketogenic diet regimen.

Ketone testing
A ketone test is used to check for the presence of ketones in the body. Ketones are acids that the body produces when it breaks down fat for energy instead of glucose. This can happen due to various reasons, such as fasting, low food intake, carbohydrate-restrictive diets, starvation, prolonged heavy exercise, or diabetes.
When to Test for Ketones
If you have diabetes, your doctor may advise you to test your ketone levels when:
- Your blood sugar level is higher than 250 mg/dL for two consecutive days.
- You are sick, injured, or planning to exercise with a blood sugar level above 250 mg/dL.
- You are pregnant or on your period.
- You've missed an insulin injection or your insulin pump stops working.
- You've had surgery or have been unable to eat.
Additionally, if you are following a low-carbohydrate "keto" diet, your healthcare provider may recommend ketone testing to monitor your ketone levels and ensure you are not at risk for ketoacidosis.
Types of Ketone Tests
There are several ways to test for ketones:
- Blood Test: A blood sample is collected from a vein in your arm using a small needle and sent for testing. You can also purchase at-home blood testing kits that use a finger-prick method and a testing strip read by a meter to determine ketone levels.
- Urine Test: This test uses a dip-and-read test strip that changes colour based on ketone levels. Urine tests can indicate your ketone levels within the last few hours but may not provide an accurate current level.
- Breath Test: Handheld breathalyzers can detect acetone, a type of ketone, but this technology is still new and may not be considered fully reliable.
Interpreting Results
A normal or negative test result typically indicates that your body is not producing an excessive amount of ketones, and you are not at risk for ketoacidosis. However, in the early stages of diabetic ketoacidosis (DKA), only one type of ketone may be elevated, and standard lab tests may not detect this. Therefore, it is important to monitor your ketone levels regularly, especially if you have diabetes or are at risk for DKA.

Ketone health risks
A ketogenic diet can lead to ketone formation. Ketones are acids that the body releases when it burns fat instead of glucose for energy. This happens when there is a shortage of dietary carbohydrates. The liver releases ketones into the bloodstream, where they travel throughout the body, providing energy.
While the potential benefits of producing more ketones can seem enticing, switching from sugar to ketone bodies for fuel isn't ideal for everyone. Here are some of the health risks associated with ketone formation:
Diabetic Ketoacidosis (DKA): Diabetic ketoacidosis is a potentially fatal complication that can occur in people with Type 1 diabetes when ketone levels in the blood or urine are too high. DKA happens when high levels of ketones and glucose in the blood cause the blood to become too acidic and toxic. This can lead to a dangerous condition called osmotic diuresis, which results in the removal of water and electrolytes from the blood, causing potentially fatal dehydration.
Dehydration: Taking ketone supplements can heighten the effects of a keto diet and make you more prone to dehydration. Ketone salts, a type of ketone supplement, usually contain sodium, which can be dangerous for people with high blood pressure.
Hypertension: Ketone esters, another type of ketone supplement, are the purest form of ketones and therefore the most potent. However, they are also expensive and have an unpleasant taste.
Nutritional Deficiencies: The keto diet is very restrictive, so it can be challenging to stick to for extended periods. This may lead to nutritional deficiencies if not carefully planned.
Other Health Risks: The keto diet may not be suitable for certain athletes and people with specific medical conditions. More research is needed to fully understand the potential risks and benefits of ketone formation and the keto diet. It is always recommended to consult a healthcare provider before starting any new diet, especially one as restrictive as the keto diet.
