Overview Of Lumen

Everyone is looking for the latest trick and trend that makes them look and feel the way they want – that’s why fitness trackers, sleep trackers, and smartwatches are some of the most popular devices in the fitness zeitgeist.

Staying healthy, however, is not all about keeping track of your activities, sleep quality, and heart rate. You also need to check what you consume. But not everyone can afford fitness experts, personal nutritionists, or trainers, which is where Lumen comes in.

According to the manufacturer, the device helps consumers understand their bodies better and the role their metabolism plays in them. With personalized nutrition information, easy-to-understand metrics, and in-app lesions, Lumen is a convenient and efficient device that helps people gain better insight into their wellbeing.

Lumen reviews also suggest it helps you figure out if you have adequate energy before a workout or require fueling up—more on that below.

How Does Lumen Work?

Lumen is a product consisting of the Lumen device and the Lumen app. The device measures your metabolism by evaluating the composition of your breath. It also measures the carbon dioxide levels in your breath to figure out if your body uses carbs or fats for fuel.

On the other hand, the Lumen app provides you with a daily measurement of your energy source – fats and carbohydrates on a scale of 1 to 5, based on your respiratory exchange ratio (RER). Lumen then uses the measurements to offer your flex score, showing how flexible your metabolism is.

Who Is The Manufacturer Of Lumen?

Lumen, a firm based in Tel Aviv, Israel, manufactures the Lumen Metabolism Tracker. The device started with twin sisters Merav and Michal –Ironman winners and Ph.D. holders in physiology.
As scientists and athletes, Michal and Merav were passionate about creating a way to offer personalized nutrition.

They believed that a healthy metabolism is a key to improved health and that everyone can attain it. However, the only way to measure metabolism was expensive and time-consuming.

Therefore, they teamed up with revolutionary entrepreneurs Daniel, Dror, and Avi, and after two years, they developed the first Lumen prototype. After four years and hundreds of beta users, the team launched Lumen on Indiegogo. Now the tech is available to all and everywhere.

What Are The Features Included in the Lumen?

Lumen consists of the following features:

Lumen Device – The portable unit measures your metabolism from your breath. You need to inhale for a few seconds and exhale for another. Sometimes you have to inhale and exhale twice to get accurate results.
CO2 Sensor – Lumen comes with a carbon dioxide sensor and flow meter that determines the CO2 concentration in your breath. It helps you figure out the form of fuel your body uses for energy.
Lumen Metabolism Tracker App – The app provides you with daily measurements of your source of energy (either carbs or fats) on a scale of 1 to 5, based on your RER. The respiratory exchange ratio is the rate between the metabolic production of CO2 and the uptake of oxygen (O2).

The Science Behind Lumen

Unlike metabolic carts, Lumen solely focuses on carbon dioxide and does not measure O2 levels or consumption. The device measures CO2 and flow rate when exhaling to determine the peak CO2 levels equivalent to alveolar gaseous concentration.

The carbon dioxide concentration is measured using a specific breath maneuver, which is by inhaling a volume of air via the Lumen device (dynamic to every individual), holding it for ten seconds, and exhaling fully.

The results are delivered in real-time through the Lumen app and stored for future reference. The tech has been scientifically proven and peer-reviewed to measure metabolic fuel usage compared to the gold standard RER for assessing metabolism in numerous validation studies.
