Does Lumen Work for Weight Loss? Plus 6 Other Lumen Reviews 2023

Are you looking for a Lumen Review in 2022? I give feedback on using the Lumen Metabolism Tracker, and if you should get one, too! But let me start by introducing myself.

Hi, my name is Jasmine, and I am a yo-yo dieter.

I’ve tried diets and different workout plans in the past. And while some have helped me with weight loss and management, I still experience weight gain after the fact. Sleep tracking was another issue I was falling behind in. 

I was looking to hack my diet and lose weight in a way that let me know if all my efforts were working. I know you can get on the scale to see if what you are trying is working, but that can take days! When it comes to counting calories and exercise, it can feel like years!

Okay, I am exaggerating here, but you get what I am saying. Those who recently started a diet plan know the agony of it all. I knew there had to be a better way to tell what worked for me and didn’t help me achieve my health goals.

And it was this thinking that led me to use the Lumen metabolism tracker. But before I get into the details of my Lumen review, you should first know that this Lumen device helps to increase your metabolic state or help you achieve healthy weight loss.

What To Expect From This Lumen Review?

This post will give you a full Lumen review of my experience using the metabolism tracker and how it compares to other diet programs I’ve done. And I will share a unique code with you to get a discount on one if you decide to buy it!

To conclude, you will know whether your lumen flex score will increase. But before I get into this Lumen review, you should probably learn more about what this device does and how it can help cut grams of carbs.

What is the Lumen Metabolism Tracker?


Let me start by saying that I’ve never heard of or used metabolism trackers. Additionally, I was pretty impressed when I learned that the Lumen Flex score is something this company crafted to get an accurate reading of your metabolism in real time.

Lumen is the world’s first hand-held, portable metabolism tracking device to accurately measure respiratory exchange ratio and metabolic state. Moreover, its claim to fame is that Lumen Fitness Tracker can hack your metabolism to lose weight and help you reduce grams of carbs.

Here is how you can increase your lumen flex score.

To begin with, this Lumen breathalyzer tracks your resting metabolic rate (rmr) to determine if you are burning more fat or cutting more grams of carbs. Naturally, you are closer to your weight loss goals if you burn fat. However, if you are burning primarily carbs, you may have some work (maybe more physical activity) to get closer to your weight-loss goals. Nonetheless, it does this by simply blowing into the device.

How Useful Is the Lumen Metabolism Tracker Flex Score?

The device syncs to its connected app that includes metabolic testing, personalized nutrition plans, and research on several other resources to learn more about healthy lifestyles so you can lose weight for good.

The Lumen health device also has a daily lumen flex score (insight) that improves metabolism by improving metabolic flexibility. Good Metabolic flexibility is your body’s ability to shift efficiently between using body fats or carbs as a source of energy. Additionally, it’s proven to meet the gold standard of metabolism measurement (RER) in multiple validation studies.

Lumen began with twin sisters Merav Mor and Michal Mor—two Ironman winners and PhDs in physiology. As scientists and athletes, they were passionate about developing a way to provide personalized nutrition plans but knew the only way to measure metabolic state was costly and time-consuming.

So they teamed up with entrepreneurs with significant experience building large companies, Daniel, Dror, and Avi. Besides that, after two years of R&D, they developed the first Lumen prototype. The prototype measured metabolism in a single breath, in less than a minute, instead of an hour-long test in a lab!

After four years of hard work and hundreds of beta users, the Lumen team launched on Indiegogo. It broke the $1 million threshold on IndieGogo in weeks, and now it is leading the way in bringing personalized nutrition to the entire world.

Does Lumen Metabolism Tracker Work? My Honest Lumen Review

I know what you are thinking. “This sounds awesome, but is Lumen Metabolism worth it?” Does Lumen work?

Tell me about my experience with Lumen: Hack your metabolism and lose weight. Believe me when I say that!

I was lucky to get a Lumen measure metabolic device to try for free! Yippee! And I used every minute to understand how Lumen calories review can be presented to you in simple words.

Lumen Metabolism Tracker in the box

According to the Lumen app, you must use the metabolism analyzer for two weeks to get your personalized flex score. Lumen Flex score reflects how efficiently your body switches between carbs and fats as fuel. So, I wanted to try it out every day for at least that time. 

During this time, I did the Lumen breath measurement test at times they recommended, which included:

  • When I first woke up
  • Before I work out
  • 30 minutes after I work out
  • After lunch
  • After dinner

I also tried low-carb days and followed the Lumen nutrition guidelines recommended in the app. While I was not always successful with this, I tried my best to stick to the meal plans. However, I did have more success losing weight with Lumen when I started using the Diet Direct meal plan instead. Read more about my experience with Diet Direct here.

The goal of the Lumen Metabolism Tracker

The goal is to burn more fat than carbs. This is how you lose weight. And it was the best gift when I could get three or fewer in the morning. 

Once I blew into the device for the day, the app gave me a nutrition and fitness plan, depending on whether I was burning more carbs or fat. And the diet plans do carb cycling, so you have high-carb and low-carb days.

Overall, it was easy to figure out because the app guided me through the steps. But then, I had to follow the instructions, and I was good to go!

The Pros Of Using Lumen

I lost weight.

In this portion of the Lumen review, I want to start by saying that I still lost three pounds in my second week of using the device, even though I did not follow all my suggestions. And what’s even more valuable is that I understand why I lost weight. This alone means to me that lumen weight loss is more permanent weight loss.

I learned how sleep, diet, and exercise affect weight loss. Even if you are doing great in one of those three areas, not having it together in another thing can affect your results! It does boost your metabolism!

Moreover, Lumen Keto can inform you about ketosis. It points out whether your body is consuming fat to produce energy for your brain. Measure CO2 with Lumen carbon dioxide insight to understand the fat or carb burning in your body.

This will help you lose weight fast and give you an idea about blood oxygen saturation. However, you should not compare this device with other water-resistant devices such as the Apple watch series, Fitbit Inspire, or Fitbit Charge.

It made losing weight fun for me.

Using the device regularly made me look at my weight loss like a science experiment. I look forward to seeing how effective my exercise was on my metabolism. And how effective some activities, such as holding your breath, are compared to others.

For example, walking in the fat-burning zone was more effective than doing yoga alone. Doing both exercises daily made a massive difference in my metabolism. 

I also realized that intermittent fasting is probably one of the easiest ways to improve your metabolism. Of course, I’ve heard this before, but it was nice to see the results.

It kept me accountable—without any guilt.

I got to a point where I knew that I had to breathe into my Lumen after a meal and got used to seeing the notifications from the app to record my breathing 30 minutes after exercise. Blowing into this device several times daily made it easier to hold myself accountable and remind myself that I am working towards better breath measurement. Even the resting heart rate monitors seemed accurate to me!

It was easy.

The best way to describe what the device was like is similar to having a personal trainer that you can carry around in your pocket.

To start, learning how to use my device was super simple. Also, holding your breath and breathing into the machine takes five minutes.

The Cons of Using Lumen

As much as the Lumen was a success, I did not like a few things about the device. And what good is a Lumen review without hearing the bad stuff, too?

It does not link directly to Fitbit.

If you are as big of a Fitbit fangirl as I am, you are out of luck for this baby to accurately track your steps. However, it links to Apple Health and Garmin, so if you are an Apple watch or Garmin user, congratulations, this will be wonderful for you.

However, if you are a Fitbit user, there is an app you can download called PowerSync for Fitbit that allows you to sync your Fitbit data to Apple Health. So, even as a Fitbit user, it still provides practical value.

Annoying, holding your breath and blow into the device.

Okay, I’ll be honest; I am trying to develop another con because this fitness performance-tracking device is fantastic! But, sure, it is a little annoying when it comes to holding your breath and blowing into this device every few hours. And you have to blow into the device 2-3 times each time to get an accurate reading.

But I also enjoy having to do this. The routine reminds me to think about my breath measurement several times a day, which, sadly, is not something I do enough.

So, while blowing into the device a few times a day can get annoying, it has more benefits in staying mindful of your diet than the annoyance of having to do it.

Update: On 3/28/2021, Lumen updated their device, so instead of blowing into the device 2-3 times for an accurate reading, you only need to blow into it 1-2 times for a precise breath measurement!

How Much Does Lumen Metabolism Tracker Cost?

Okay, so you probably wonder what works as your trainer, nutritionist, sleep advisor, and so much more costs you.
