Embarking on a ketogenic lifestyle often involves monitoring key biomarkers to gauge progress and optimize results. Among the tools available, the Keto-Mojo meter stands out for its ability to measure both blood glucose and ketone levels. This article delves into the intricacies of Keto-Mojo readings, providing a structured understanding of their significance and application.
The Importance of Blood Glucose Monitoring
Blood glucose, also known as blood sugar, serves as a primary indicator of diabetes risk. Elevated blood sugar levels correlate with increased risk factors. However, blood glucose is not solely a marker for diabetes; maintaining blood sugar levels within a normal range is crucial for overall metabolic health.
Target Blood Sugar Levels
Defining target blood sugar levels remains a topic of debate. Moreover, assessing metabolic health extends beyond simply measuring blood glucose. Various other biomarkers play a vital role.
Glucose, a form of sugar or carbohydrate, is essential for survival. Red blood cells, for instance, rely exclusively on glucose for fuel. During periods of scarcity, such as fasting, blood sugar levels do not drop to zero. However, in individuals with obesity or diabetes, glucose is often abundant.
The relationship between dietary sugar, blood sugar, and diabetes is complex. When we consume a meal, blood sugar rises, prompting the pancreas to secrete insulin. Insulin facilitates the movement of blood sugar from the bloodstream into cells for storage. However, consistent sugar intake can overwhelm the system, leading to insulin resistance.

Insulin Resistance Explained
Insulin resistance refers to the impaired ability of insulin to effectively store blood sugar in muscle and liver cells. In this state, blood sugar remains elevated for prolonged periods.
Measuring Blood Glucose Levels
To assess metabolic health, measuring blood glucose levels is essential. Fasting blood sugar and postprandial blood glucose can be easily measured at home using a glucose meter. This involves pricking a finger, inserting a test strip, and recording the result.
The Value of Blood Sugar Testing
Blood sugar testing offers valuable insights into how different foods affect the body. By taking a baseline reading (at least 3 hours after the last meal), consuming a specific food, and then testing one or two hours afterward, individuals can observe which foods cause blood sugar spikes.
Ideal Blood Sugar Ranges
For fasting blood glucose, levels below 85 mg/dl (4.7 mmol/L) are generally considered optimal. Postprandial blood glucose should ideally exhibit minimal spikes, with increases of less than 30 mg/dl over baseline at one hour post-meal. Blood sugar levels should return to near baseline within three hours after eating. For example, if your baseline is 85 mg/dl (4.7 mmol/L), you don’t want to exceed 115 mg/dl (6.4 mmol/L).
Limitations of Blood Glucose Measurements
Fasting blood sugar and postprandial blood glucose measurements may not always provide the most reliable assessment of metabolic health. Factors such as stress, poor sleep, and the "dawn effect" (a natural release of cortisol in the early morning) can influence blood glucose levels. Therefore, it's advisable to measure HbA1c and insulin levels in addition to blood glucose. Measuring the insulin response following an oral glucose tolerance test (OGTT) can provide insights into metabolic flexibility.

Strategies for Blood Sugar Control
To maintain healthy blood sugar levels, consider the following strategies:
- Exercise regularly
- Prioritize sleep
- Reduce carbohydrate intake
Adopting a ketogenic lifestyle, with or without intermittent fasting, can further enhance blood sugar control.
Understanding Ketone Levels
Ketone production is a natural process that can be measured at home using devices like the Keto-Mojo meter. These meters detect the concentration of ketones in the blood, in addition to measuring blood sugar levels.
Ketone Production and Nutritional Ketosis
Our bodies constantly produce ketones, but their production is suppressed in individuals who consume carbohydrates regularly. A typical ketone reading for someone on a carb-based diet would be in the range of 0.0-0.2 mM. Nutritional ketosis is generally defined as having ketone levels at or above 0.5 mM.
Factors Affecting Ketone Levels
Blood ketone levels are highly sensitive to dietary changes. Consuming even a moderate amount of carbohydrates can disrupt ketosis and cause ketone levels to drop significantly.

Ketone Levels and Goals
The optimal ketone level varies depending on individual goals. For weight loss, achieving "light nutritional ketosis" (0.5 mmol/L-1.0 mmol/L) is a good starting point, with a subsequent aim for "optimal ketosis" (1.0 mmol/L-3.0 mmol/L).
Individuals using the ketogenic diet for therapeutic benefits related to medical conditions like epilepsy, cancer, or endocrine and metabolic disorders may aim for higher ketone levels, typically in the 3.0 mmol/L -5.0 mmol/L range. Those who are fasting or consume a very high-fat diet may reach levels in the 3.0 mmol/L-8.0 mmol/L range.
Exercise and Ketone Levels
Exercise can influence ketone levels, with varying effects depending on the type of exercise. Anaerobic exercise (high-intensity, short duration) tends to decrease circulating ketones and slightly increase blood glucose. Aerobic exercise (swimming, walking, jogging, cycling) generally leads to an increase in circulating ketones.
Avoiding Extreme Ketone Levels
It's important to note that aiming for extremely high ketone levels is generally unnecessary and may not provide additional benefits. The exception is for individuals with type 1 diabetes, who need to be cautious about ketoacidosis, a serious condition requiring medical attention.
Using Ketone Levels as a Tool
Rather than stressing over specific ketone levels, consider them a tool for evaluating and adjusting eating habits within the ketogenic framework.
Using the Keto-Mojo Meter
The Keto-Mojo meter offers a convenient way to track and monitor ketone levels, view trends and graphs, and share readings with healthcare providers.
Preparing for Testing
- Twist off the top of the lancing device.
- Insert a new lancet into the device.
- Adjust the depth selector to the appropriate setting for your skin type (ranging from lightest to deepest).
- Grip the finger you are going to test with your index finger and thumb of your other hand and squeeze for about 12 seconds before using the lancet.
Performing the Test
- Ensure the test strip is pushed all the way down in the port with the strip facing up. The meter will automatically turn on.
- Wait for the meter to display a flashing droplet icon.
- Test on the side of your finger where the skin tends to be softer. For men or people with calloused hands, use your ring or pinky finger.
- Wipe away the first blood droplet with a clean paper towel or tissue for a more accurate result.
- Do not place blood on the top of the strip.
- Ensure a good fill by keeping the strip to the blood droplet until the channel is completely full and the meter starts to countdown.
- If testing both glucose and ketones, conduct the tests back to back, using the same blood droplet if sufficient.
