Metabolism tracker: Lumen Reviews


The Lumen Metabolism Tracker is a new device that helps people understand their metabolism. It tells you whether your body is burning fat or carbohydrates. 

You can use it to make better choices about what to eat and how to exercise. This lumen review will explain how the Lumen works, its benefits, and its drawbacks.

What is the Lumen metabolism tracker?

The Lumen is a small device that measures carbon dioxide (CO2) in your breath. It helps determine whether your body is burning fats or carbohydrates for energy. You use it by breathing into the device and sending the data to an app. 

The app gives you daily advice on how to eat and exercise based on your metabolism.

How does Lumen work?

You take a breath test by inhaling through the device, holding your breath for a few seconds, and then exhaling into the device. The device analyzes your breath to see how much CO2 is present. 

The app then shows whether you are burning fat or carbs. Based on this, it gives you tips on what to eat and how to exercise to improve your metabolism.


The Lumen provides personalized insights into your metabolism, which means the advice you get is specific to your body’s needs. It gives daily recommendations for food and exercise and allows you to track your progress over time with graphs and charts. 

The device is easy to use; it requires only a simple breath test. You can connect Lumen with other health apps like Apple Health and Google Fit.

Detailed functionality

You can better understand the Lumen’s functionality by exploring how it operates daily. Each morning, you start with a breath test to see how your metabolism is functioning at the start of the day. 

Based on these readings, the app will tell you what type of breakfast would be most beneficial for you. You can take additional breath tests throughout the day to monitor how your body responds to different foods and activities.

For example, if you eat a high-carb meal, you might use Lumen to see how long it takes for your body to switch from burning carbs to fats. This real-time feedback helps you understand how different foods affect your metabolism and energy levels.

Benefits of using Lumen

You can improve your metabolic health with Lumen. Knowing whether you are burning fats or carbs helps you make better choices. The personalized nutrition advice can help you stick to a diet that works for you. 

Optimizing your workouts based on your metabolism can lead to better performance. Tracking your progress helps you see how your body is changing and improving. Using Lumen regularly can lead to long-term health benefits.

Personalized Nutrition

One of Lumen’s standout features is its ability to provide personalized nutrition advice. Instead of following a one-size-fits-all diet plan, you get recommendations tailored to your unique metabolic profile. 

This can increase the effectiveness of your diet, as you are eating foods that are optimal for your body’s current state.

workout performance

Knowing your metabolic state can help you optimize your workouts. For example, if Lumen indicates that you are burning carbohydrates, you might engage in high-intensity exercise to maximize fat burning. 

If you are burning fats, you might focus on endurance training. This targeted approach can help you get the most out of your exercise routine.

Weight management

Lumen’s insights can help you manage weight by helping you understand how your body responds to different foods and activities. Adjusting your diet and exercise routines based on your metabolic readings can create a more effective weight management plan.
