Does Lumen Work For Weight Loss? Plus 6 Other Lumen Review

Are you looking for a Lumen Review in 2025? I will provide feedback on using the Lumen Metabolism Tracker and suggest whether you should consider getting one as well. 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 area where I was falling behind. 

I was looking to hack my diet and lose weight in a way that would 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.

This thinking led me to use the Lumen metabolism tracker. However, before I delve into the details of my Lumen review, it’s essential to understand that this device helps boost your metabolic state and support healthy weight loss.

What To Expect From This Lumen Review?

This post will provide a comprehensive review of my experience with Lumen, including my thoughts on its effectiveness as a metabolism tracker and how it compares to other diet programs I’ve tried. I will also 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. However, before I delve into this Lumen review, it’s essential to understand what this device does and how it can help reduce carb intake.

Let me start by saying that I’ve never heard of or used metabolism trackers. However, I was quite impressed when I learned that this company developed the Lumen Flex score to provide an accurate real-time reading of your metabolism.

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

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.

The device syncs with its connected app, which includes metabolic testing, personalized nutrition plans, and access to various resources to learn more about healthy lifestyles and achieve permanent weight loss.

The Lumen health device also features a daily Lumen Flex score (Insight) that enhances 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 has been proven to meet the gold standard of metabolism measurement (RER) in multiple validation studies.

Lumen began with twin sisters, Merav Mor and Michal Mor, who are both Ironman winners and hold 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, such as Daniel, Dror, and Avi. Besides that, after two years of R&D, they developed the first Lumen prototype. The prototype measures metabolism in a single breath, in under a minute, rather than the hour-long test typically conducted in a lab.

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

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! I used every minute to understand how the Lumen calories review can be presented in simple words.

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 the 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. Although I was not always successful with this, I made an effort 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 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 provided me with a personalized nutrition and fitness plan, depending on whether I was burning more carbs or fat. The diet plans involve carb cycling, which alternates between high-carb and low-carb days.

Overall, it was easy to figure out because the app guided me through the steps. I just 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 note that I still lost three pounds in my second week of using the device, despite not following all my suggestions. What’s even more valuable is that I understand why I lost weight. This alone means to me that Lumen’s weight loss is more permanent.

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

Moreover, Lumen Keto can inform you about ketosis. It indicates whether your body is utilizing fat to generate energy for your brain. Measure CO2 with Lumen Carbon Dioxide Insight to understand how your body burns fat or carbs.

This will help you lose weight quickly and provide an indication of your blood oxygen saturation. However, you should not compare this device with other water-resistant devices such as the Apple Watch series, the Fitbit Inspire, or the Fitbit Charge.

It made losing weight fun for me.

Using the device regularly made me view my weight loss as 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 reached the point where I knew I had to breathe into my Lumen after a meal and became accustomed to seeing notifications from the app to record my breathing 30 minutes after exercise. Blowing into this device several times a day made it easier for me 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.

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

Although the Lumen was a success, I had a few reservations 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 a Fitbit fangirl as I am, you are out of luck with this device accurately tracking your steps. However, it integrates with 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 available for download called PowerSync for Fitbit that allows you to sync your Fitbit data with Apple Health. So, even as a Fitbit user, it still provides practical value.

Holding your breath and blowing into the device isn’t very pleasant.

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 you have to hold your breath and blow into it every few hours. You must blow into the device 2-3 times each time to obtain an accurate reading.

However, I also enjoy doing this. The routine reminds me to take my breath measurement several times a day, which, sadly, is not something I do often 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 March 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.

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

Not as much as you may think! The app is free, and the device is $299. However, if you use our promo code MISSMILLMAG, you will receive $25 off your order!
