Lumen And Keto: Does It Work?

The ketogenic diet is a low-carb, high-fat, and moderate-protein diet that has gained popularity in recent years. Lumen is a device that tracks your metabolism and can be used to monitor whether your body is burning fat or carbohydrates for fuel. While the ketogenic diet restricts carbohydrate intake to a minimum, Lumen provides insights and directions to help you burn fat and lose weight in a healthier way. It is a portable, home-use metabolic device that can be useful for those on the keto diet to track their metabolic responses to dietary changes.

Lumen measures metabolic flexibility

Lumen is a metabolism tracker that can tell you whether your body is using carbohydrates or fat for fuel. It does this by measuring the CO2 levels in your breath, which it uses to interpret your metabolism. This is known as the respiratory exchange ratio (RER).

Lumen provides a daily measurement of your source of energy on a scale of 1 to 5, based on your RER. It then uses these measurements to provide a flex score, showing how flexible your metabolism is. This measurement is a comprehensive evaluation of your metabolism, based initially on two weeks of measurements and other tracked metabolic factors.

Lumen's method is slightly different from the keto diet in that it trains your metabolism to use exclusively fats or carbs and switch between the two more easily. The keto diet, on the other hand, is defined as any diet that increases fat consumption to around 60% of total calories consumed, while also increasing protein intake moderately and decreasing carbohydrate intake to 5-10% of total calories.

Lumen can be a valuable tool for those on a keto diet, as it can provide insights into how their metabolism is working and how it is impacted by specific foods. It can also be used to validate whether a low-carb diet is helping to improve metabolic flexibility.

However, it is important to note that Lumen is not 100% accurate and there are certain factors that can impact the accuracy of its readings, such as elevated heart rate. Additionally, Lumen's meal recommendations have been criticised for their reliance on plant-based foods.

Lumen is a breath analyser

To use Lumen, you simply breathe into the device. The idea behind it is not new, as it leverages breath analysers that measure what is known clinically as the respiratory exchange ratio (RER). The RER describes the ratio between the amount of oxygen (O2) you inhale and the amount of carbon dioxide (CO2) you exhale. If you follow a high-carb diet, your body only uses carbs for fuel, and your breath contains high CO2 levels. On the other hand, someone who follows a low-carb, high-fat diet burns mostly fat for fuel and exhales lower CO2 levels. Metabolic breath analysers like Lumen detect the amount of CO2 in your breath and tell you whether you are burning carbs or fat for fuel.

Lumen is the first hand-held and portable metabolism tracker that enables people to get insights into how their metabolism is doing. It is a fascinating device that offers a unique way to improve one's metabolism and metabolic flexibility. It is also a great alternative to measuring ketone levels in your blood, urine or breath. The mobile app is quite interactive and inspires enough curiosity to help you keep going. While testing the device, I looked forward to my Lumen score every morning almost as much as I look forward to my WHOOP recovery score.

Lumen can support your journey towards better health by encouraging you to take regular measurements and by nudging you to adjust your carbohydrate, protein and fat intake based on personalized meal recommendations. It can be a convenient alternative to blood glucose and ketone monitors. Of course, Lumen and blood testers test for entirely different biometric parameters, but both can give you an indication of whether your body is burning fat or carbs for energy.

Lumen is a portable metabolic tracker

To use Lumen, you breathe into the device after a standardised seated rest period. The process involves a deep inhalation with a 10-second breath hold, followed by a flow-rate-controlled exhalation. The device then provides real-time information about your metabolism and guides you towards better dietary habits. It also has a food log feature that helps you understand how the food you eat impacts your metabolism.

Lumen is based on the concept of metabolic flexibility, which is the body's ability to switch between burning carbohydrates and fats for fuel, depending on the types of food available. Modern diets, which are high in processed carbohydrates, can lead to a chronic dependence on glucose as a source of fuel, resulting in constantly fluctuating energy levels and insulin resistance. Lumen helps address this issue by providing insights into your metabolic state and guiding you towards a diet that improves your body's ability to leverage fat for energy.

Lumen is especially useful for those on a ketogenic diet, as it can help them understand how their body is responding to the diet and make any necessary adjustments. It is also beneficial for those who are not sure how particular foods interact with their body, as it can help them optimise their diet and make better food choices.

Lumen costs $299 and includes one free month of membership. After that, you can continue using the device for unlimited real-time metabolic measurements with no subscription required. However, if you want additional benefits like lifestyle insights, daily personalised nutrition plans, and metabolic coaching, you can opt for the $19 per month membership.

Lumen can be used alongside keto

Lumen is a device that can be used alongside keto to track your metabolism and help you burn fat. It is a metabolism tracker that can tell you whether your body is using carbohydrates or fat for fuel. The device consists of a CO2 sensor and a flow meter that measures how much air you inhale and exhale. The device connects to an app running on your phone via Bluetooth, where all your data is stored and interpreted.

Lumen can be a valuable tool for people following a keto diet as it provides insights into how their body is responding to the diet. It can help them understand how their meals impact their metabolism and guide them towards better dietary habits that enable their body to leverage fat for energy instead of relying solely on carbs. This can be especially useful for people who are unsure about how particular foods interact with their body.

Lumen also offers a food log feature that allows users to track how specific foods affect their metabolism. The app provides a library of information, including macronutrient data, how-to videos, and personalized insights related to metabolism. Additionally, Lumen provides daily insights, ideas, and directions to help users lose weight and burn fat more healthily.

Lumen can be a useful tool for people following a keto diet as it provides them with real-time information about their metabolism and helps them make better dietary choices. It is important to note that Lumen does not provide meal plans but instead suggests how many servings of carbs, fat, and protein one should be eating per day.

Lumen has been shown to be effective in tracking metabolic responses to dietary changes. A study found that Lumen detected significantly increased expired CO2 in response to a high-carbohydrate meal and may be useful in tracking mean weekly changes to acute dietary carbohydrate modifications. This indicates that Lumen can be a valuable tool for people following a keto diet as it can help them understand how their body is responding to the diet and make any necessary adjustments.

Lumen is a personalised nutrition plan
