Losing weight is a common concern for many people, and it’s not uncommon for people to try out different methods in their bid to shed some pounds. One of these methods is the use of Lumen, a device that claims to help individuals lose weight simply by breathing into it. This article aims to explore what Lumen is, how it works, and whether it can indeed help you lose weight.

What is Lumen?

Lumen is a device that was created by a company known as Lumen Metabolism. The device is designed to measure the amount of carbon dioxide in your breath, and through this, give you an estimate of whether your body is burning fats or carbs. Lumen uses a scientific concept called Respiratory Quotient (RQ) to determine your metabolic rate by analyzing your breath.

According to Lumen Metabolism, when you breathe into the device, Lumen analyzes your breath and immediately tells you whether you’re burning carbs or fats. The device then suggests a personalized nutrition plan based on your metabolic rate to help you lose weight.

How does it work?

When we breathe in oxygen, our bodies convert it to energy through a process called metabolism. During this process, our bodies either burn fats or carbs, depending on the type of activity we’re doing. When we’re resting or doing light activities, our bodies burn fats. On the other hand, when we’re engaging in high-intensity exercises or activities, our bodies burn carbs.

Lumen’s technology works by analyzing the amount of carbon dioxide you exhale, which directly correlates with your metabolic rate. The device then tells you whether you’re burning fats or carbs, and helps you adjust your nutrition plan accordingly.

Can Lumen really help you lose weight?

Based on the science behind it, Lumen seems like a promising weight loss tool. By analyzing the type of fuel your body is burning, you can adjust your nutrition plan to ensure that you’re consuming the right amount of carbs and fats to help you lose weight. A study conducted by Lumen Metabolism reported that participants who used the device and followed the customized nutrition plans lost an average of 6.8 pounds in 30 days.

However, it’s important to note that Lumen is not a magic tool that will help you lose weight overnight. It’s still up to you to maintain a healthy diet and engage in regular physical activity to achieve sustainable weight loss.

How accurate is Lumen?

The accuracy of Lumen has been a subject of debate, with some experts questioning its reliability. Some experts claim that the use of a single breath to determine metabolic rate is not sufficient since several factors influence one’s metabolic rate, such as age, weight, gender, and activity level.

However, Lumen Metabolism conducted a study with a sample size of 40 individuals, and the results showed that Lumen’s estimates were within a 10% margin of error compared to metabolic rate measurements through indirect calorimetry.

How much does Lumen cost?

Lumen is currently priced at $299 on their official website. The device comes with a mobile application that allows you to track your progress and provides personalized nutrition plans based on your metabolic rate.


Lumen seems to be a promising weight loss tool based on the science behind it. However, it’s important to remember that it’s still up to you to maintain a healthy diet and engage in regular physical activity to achieve sustainable weight loss. Lumen is also not a substitute for professional medical advice, and it’s recommended that you consult with a healthcare provider before using the device.

Q: Does Lumen require any calibration?
A: Yes, Lumen requires calibration every 8-12 weeks to ensure accurate readings.

Q: Can multiple people use one Lumen device?
A: Yes, multiple people can use one Lumen device by creating their personalized profile on the app.

Q: How long does it take to get Lumen readings?
A: The device takes around 1-2 minutes to analyze your breath and give you the readings.

Q: Does Lumen ship internationally?
