Have you heard the buzz about the new Lumen metabolism tracker? This home metabolic tracking device is revolutionizing the way people approach their weight loss journey, fitness and nutrition.

It is a handheld device and app that can measure your metabolism using your breath. The amount of oxygen you breathe in and carbon dioxide you breathe out contains a surprising amount of information about how you process food.

The device which was launched worldwide in May this year is the brainchild of Michal and Merav Mor, twin sisters who are both scientists and endurance athletes.

It has been developed through years of scientific testing and validation by Lumen, the company behind the device that the sisters co-founded, which has always been at the forefront of health technologies geared towards improving personal health.

If you are curious about the lumen metabolism tracker, then here’s a comprehensive review of this amazing metabolism hacker device.

What Is The Lumen Metabolism Tracker?

The lumen metabolism tracker is a device that measures the concentration of your body’s carbon dioxide levels. These levels are calculated based on Lumen’s vast scientific research and development.

It will indicate the type of fuel that your body is using in order to produce energy, which is a mixture of fats and carbs. According to Michal Mor Ph.D., the co-creator of Lumen,

“Lumen provides you with a personal nutrition plan, which contains the amount of protein, carbs, and fat you should eat.”

This handheld device is very portable. In fact, using this device is said to be like having a nutritionist in your pocket. It offers personalized suggestions on when you should eat, and which types of food to eat in order to fuel your daily activities.

These suggestions are all personalized since the device will consider your body’s metabolic rate.

Aside from supporting your body’s fat-burning abilities, it will also help improve your metabolic flexibility, which is your body’s ability to switch from using carbs to fats for energy. This makes it ideal if you are currently following the keto diet or low carb diet and want to learn how many carbs your body really needs.

Dr. Mark Hyman , Functional Medicine Doctor, says:

One of the things that I really love about Lumen is that everyday Lumen tells me how to adjust my nutrition plan based on my body’s actual needs.

What Can the Metabolism Tracker Do For You?

Let’s now look at the ways you can benefit from using the Lumen metabolism tracker so you can fully understand.

Personalized Nutrition

The tracker is a very portable device that can fit easily in your pocket. Just like a nutritional health coach, it will train your metabolism by telling you what to eat and when to eat to fuel up your workout while improving metabolic flexibility and supporting fat burn.

When your metabolism is more flexible, you are better able to burn fat instead of carbs, leading to lasting weight loss. No more yo-yo dieting!

Easily keep track of your metabolism

You may have heard it said that that your metabolism cannot be changed but that is pure myth. With this device your metabolism is under your control.

It can help you find out how it’s affected by your physical activity, sleep, and nutrition. With this information you can change your metabolism for the better.

Over time, Lumen trains your metabolism to use the food you eat more efficiently. This is  known as metabolic flexibility.

Customize your nutrition

Receive personalized daily meal plans so you will know exactly what to eat and when to eat.

If you feel stuck at any stage Lumen offers a free 30 minute one-on-one Zoom consultation with a nutritionist to see if further in depth consultations might help.

Optimize workout

The device will let you know if you’ve got enough energy before a workout or if you need to fuel up more. It gives you the reason why too.

Monitor your metabolic health

Over time, the lumen metabolism tracker will be able to keep track of your metabolism, nutrition, sleep, and fitness data. It will provide you with a Lumen Flex Score, which indicates your level of success.

The aim behind Lumen is to improve a person’s “metabolic flexibility,” which is how efficient a person’s metabolism is at switching between fuel sources when needed. More about the flex score below.

A Convenient Way of Tracking Metabolism

Instead of going to a lab and paying expensive fees, this device allows you to track your metabolism at home or wherever you want to.

How to Use Lumen Metabolism Tracker?

The lumen metabolism tracker might be a new concept for many people, but using this device is not at all complicated. In fact, the way it works is pretty interesting. You just need to breathe into it three times and the device will start working.

It will calculate the concentration level of your carbon dioxide and will tell you via an app if most of the calories that you burn are fats or carbohydrates. You will receive a score of 1 to 5, which indicates how your body is using energy.

A score of 1-2 is the ideal “fat burning” state. If your body is running on energy from the carbohydrates you’ve consumed the score will be 4. A combination of both scores as a 3.

In order to achieve the best results in using the lumen metabolism tracker, take your measurements while the body is in a relaxed state, if possible while sitting. If you’ve just performed any activity that could increase heart rate, rest for at least 30 min before you start using the device.

You can use the tracker at any time throughout the day. However, taking measurements in the morning is said to provide you with the most insightful reading since it can capture your body’s metabolism while at a resting state.

Pricing and Warranty

When buying the lumen metabolism tracker, you will also get a charging dock and USB cable, aside from the device itself. You will also receive a travel case, as well as free access to the Lumen app membership.

Currently, the device is being sold at a discounted rate of $299 and you’ll get a 10% discount if you purchase two or more.
