The ketogenic diet has gained popularity in recent years, with many enthusiasts touting its weight loss benefits. The diet involves significantly reducing carbohydrate intake, which lowers the body's glucose levels. As a result, the body enters a state called ketogenesis, where it burns fat for energy instead of glucose. While on a ketogenic diet, it is important to monitor glucose levels to ensure they remain within a healthy range and to identify any trigger foods that may cause a spike in glucose levels. Testing glucose levels can also provide insight into metabolic health and help manage conditions like diabetes. Testing can be done using blood glucose monitors, which are relatively affordable and easy to use, with optimal fasting blood sugar levels falling between 70 mg/dl and 85 mg/dl (3.9 and 4.7 mmol/L). For those on a ketogenic diet, testing glucose levels can be a useful tool to ensure the diet is achieving the desired results.

What You'll Learn
How often should I test my glucose levels?
The frequency of glucose testing depends on your goals and health status. If you are monitoring your health and diet, testing once a day is adequate. Testing once a day will give you a good baseline to compare over time. If you are using the ketogenic diet for therapeutic benefits around medical conditions, you may want to test more frequently, such as before each meal, to closely monitor how your body is responding.
It is important to test at the same time each day for consistency and to ensure you are getting an accurate picture of your progress. Testing in the morning, before ingesting anything, helps you avoid the "dawn effect", a natural early-morning increase in blood sugar/glucose. For someone without insulin resistance, testing an hour after waking will generally provide a good fasted baseline. However, for someone who is insulin-resistant, it may be better to wait 2-3 hours after waking to allow your body more time to adjust to the cortisol spike.
If you are testing multiple times a day, it is recommended to test right before lunch or dinner, at least 2-3 hours after you have eaten any other food or drink. This ensures that you get a true reading of your progress, as consumption of almost any food will cause your glucose to go up. Testing before a meal and then 60 minutes and 3 hours afterward is a great way to find out how your body responds to various foods.
In addition to measuring blood glucose levels, it is important to measure HbA1C and insulin levels, as well as your GKI (Glucose Ketone Index), to get a complete picture of your metabolic health.

What are the best tools for testing?
The aim of a ketogenic diet is to enter a state of ketosis, where your body burns fat stores for fuel instead of relying on glucose. To know if you're in ketosis, you need to measure ketones in your blood or urine.
There are several tools available for testing glucose and ketone levels. Here are some of the best options:
Urine Strips
Urine strips are a convenient and inexpensive way to find out if you're in ketosis, especially during the first few weeks of a ketogenic diet. They are easy to use and can provide valuable information about your ketone levels. However, they may not be as accurate as blood tests and are better suited for initial testing.
Blood Glucose and Ketone Meters
Blood glucose and ketone meters offer precise readings, ensuring you stay in optimal ketosis. These meters can be used to measure both glucose and ketone levels, providing a comprehensive understanding of your body's fuel usage. Look for meters with high precision, quick results, and affordable test strips. Some popular options include:
- Keto-Mojo GK+: This meter comes with a free app and Bluetooth connectivity, allowing you to sync your blood glucose and ketone test results to your smartphone. It also calculates your Glucose Ketone Index (GKI), helping you understand your body's metabolism.
- CareTouch: This meter has better built-in data features and can store up to 1,000 readings. It also averages ketone readings over different periods.
- Nova Max: While it stores fewer readings (400), it averages blood glucose readings.
- Precision Xtra: This meter stores 450 readings and averages blood glucose levels.
When choosing a blood glucose and ketone meter, ensure that it is compatible with ketone test strips and check for any additional requirements, such as subscriptions or companion apps.
Cholesterol Testing Kits
Maintaining optimal cholesterol levels is important for long-term heart health. Cholesterol testing kits allow you to monitor your HDL, LDL, and triglyceride levels at home, providing a comprehensive view of your metabolic health.

What are optimal glucose levels?
A ketogenic diet involves drastically reducing carbohydrate intake, which deprives the body of exogenous glucose. The body breaks down carbohydrates into glucose to use as fuel, so a keto diet minimises blood sugar response.
Optimal fasting blood sugar ranges are between 70 mg/dl and 85 mg/dl (3.9 and 4.7 mmol/L). However, individual glucose baselines will differ from person to person depending on health history, length of time following a keto diet, and activity level.
The Glucose Ketone Index (GKI) gives an overall view of metabolic status and the state of ketosis. It is calculated by taking your glucose reading (mg/dl) and dividing it by 18, then dividing that number by your ketone reading. Testing your GKI twice a day is recommended when starting a ketogenic diet, and once a day is adequate for maintaining ketosis.
Blood glucose monitors are relatively affordable and provide an immediate picture of how your body is responding to specific foods, meals, and activities. Testing blood glucose can help identify trigger foods that spike glucose and adversely affect ketone levels. It is also useful for managing weight loss, as it can reveal the impact of adding post-workout carbs or starchy vegetables to your diet.
To keep blood sugar under control, it is recommended to exercise, sleep, and keep carb intake low.

How does ketosis affect glucose levels?
A ketogenic or keto diet involves eating very few carbohydrates, which deprives the body of exogenous glucose, or glucose sourced from outside the body. When glucose availability is low, the body enters a state called ketogenesis, in which ketone bodies are created from fatty acids and replace glucose as the body's primary energy source.
Ketone levels in the blood can be measured in several ways, including blood monitors, breathalysers, and urine testing strips. Blood glucose levels can be measured using blood glucose monitors, which are relatively affordable and easy to find.
When following a keto diet, it is recommended to test your ketone and glucose levels twice a day: after waking and before lunch or dinner. Testing at the same time each day is important for tracking your progress. Testing before eating anything but after being awake for a while helps avoid the "dawn effect", which is an early-morning increase in blood sugar caused by a natural rise in cortisol before waking.
Ketone and glucose testing can help identify trigger foods that spike your glucose and adversely affect your ketone levels. Testing can also help you understand how long it takes for your glucose levels to stabilise. If your ketone levels are 1 mmol/L or higher during your anticipated lowest levels of the day, it means you are likely in a deep state of ketosis.
While ketosis is beneficial for most people, it can be dangerous for certain groups, such as people with type 1 diabetes, who are at risk of developing ketoacidosis, a condition caused by a lack of sufficient insulin.

How does glucose testing help with diabetes?
Glucose testing is a vital tool for diabetes management. A blood glucose test measures the glucose (or sugar) levels in your blood. Glucose is the body's main source of energy, and it comes from the food we eat. Insulin, a hormone, helps move glucose from the bloodstream into our cells, where it is used as energy.
High blood glucose levels, known as hyperglycemia, can indicate prediabetes or diabetes. Prediabetes is when your blood glucose levels are higher than what is considered healthy, but not high enough to be classified as diabetes. If you have diabetes, your body either cannot produce insulin or cannot use it effectively, so glucose remains in the blood and does not reach the cells. This can lead to a dangerous increase in glucose levels. Uncontrolled blood glucose can cause severe long-term health issues, such as heart disease and nerve damage.
Glucose testing helps people with diabetes manage their condition effectively. It allows them to monitor their glucose levels and adjust their diet and treatment accordingly. Testing can also reveal “trigger foods" that cause spikes in glucose levels, enabling people with diabetes to make informed dietary choices to maintain healthy glucose levels.
Additionally, glucose testing is useful for diagnosing diabetes. Both type 1 and type 2 diabetes can cause low blood glucose levels, or hypoglycemia, often due to diabetes medications. Low blood glucose can also be caused by certain medical conditions, such as kidney or liver diseases. Untreated, severe low blood glucose can result in seizures and brain damage. Therefore, glucose testing is crucial for detecting and managing diabetes to prevent potential health complications.
