Lumen: Two-minute review

Are you currently burning carbs or fat? Lumen, a tiny breathalyzer equipped with Bluetooth to sync with an app for smartphones and the Apple Watch, will tell you. Why do you need to know? Your body’s metabolism is very important. It provides energy to cells and organisms and plays an important role in weight loss. But while fitness trackers, smartwatches, heart rate monitors, and smart scales will tell you exactly what activities you’ve done and monitor your progress – be it better fitness or weight loss – they won’t tell you how efficient your body is at burning calories. , or what and when to eat.

Lumen: Two-minute review

Lumen helps you achieve ‘metabolic flexibility. This is effective when you start the morning burning mostly fat and then switch to carbs depending on your activity. Overall better energy levels, more effective weight loss, and is able to see the effect exercise/run/swim/hike has on your body.

Is it backed by science? Lumen says its device has been validated as a metabolic measurement tool by a study (opens in new tab) conducted by San Francisco State University.

A device no bigger than a pair of truly wireless earbuds in its battery case and modeled on the kind of pocket-sized devices that analyze your breath for alcohol levels, the Lumen is a little e-cigarette/ Looks like a vaping device.

It’s just as easy to use. You fire up an app, follow the breathing instructions, hold your breath for 10 seconds, exhale, then wait for the results, which arrive a few seconds later and tell you exactly. What your metabolism is currently burning: mostly fat, mostly carbohydrates, or somewhere in between. It does this by monitoring the level of CO2 in your breath (more CO2 = carbs, less CO2 = fat).

Also, it doesn’t actually do anything that quickly. Our long-term test, constantly required retaking the breath test, meaning measurements took longer than advertised. When you are asked to do this several times a day, it becomes quite overwhelming. Lumen is in need.

Despite the fact that it gives the user very specific insights, actions, and nutritional advice, whether Lumen succeeds in being a practically useful tool in health tracking depends largely on how committed the user is. Is. You’ll either love Lumen or quickly forget all about it, but it’s a new way to optimize your health, fitness, and diet.

  • 74 grams weight
  • Soft touch material
  • The charging cradle uses USB-C.
  • Design Score: 4/5

The breathalyzer – which has a CO2 sensor and a flow meter inside – is a better piece of kit that feels expensive. A soft-touch matte finish sees it through, even though the mouthpiece is metal, which adds a premium feel as you inhale and exhale. On the front is a ring of LEDs that light up to indicate different modes: green for charging, and purple for connecting to your phone.

Although it’s designed to sit on a USB-C cable-powered charging base, the Lumen’s battery lasts about 14 days, which means you can take it on a trip without having to move the charging base. During our tests, Lumen and the app always connected automatically and there were no dropouts, lags, or connectivity issues of any kind. It even senses if your heart rate is particularly high and prompts you to sit for a while before taking a measurement.

However, it is a clever product in more ways than one. After a few weeks, the saliva accumulates and when you blow it, it comes out at the bottom. As well as requiring periodic cleaning, it’s best not to share your Lumen with anyone but a very close family – although technically it can be shared with someone else when Until they download the Lumen app on their smartphone separately and create their own.

Lumen metabolism tracker: Performance

Lumen metabolism tracker: Performance

  • Often two breath samples are required.
  • Quite demanding
  • It takes two weeks to get serious.
  • Performance Score: 3/5

Although it is advertised as a tool that takes only 10 seconds to use, in practice it is a time-consuming tool. You’re encouraged to use it about 30 minutes after waking up, before eating, after eating, before exercising, and the last thing at night (which the last thing is especially hard to remember). This routine is made more difficult to follow by Lumen which often requires two breath patterns, doubling the commitment required. The app also prompts the user to wait 15 seconds between samples.

This is the real problem with Lumen; Instead of the honeymoon period you get with most new gadgets, this one gives you the opposite through an annoying new daily routine and a lack of insight in return. This is a problem because after just two weeks of continuous use you get a weekly summary, a ‘Lumen Flex Score’ (an indicator of your metabolism’s flexibility), and a personalized nutrition plan.

The more Lumen you use, the more it does for you. If you sample before a workout, it gives advice based on your results. So after telling Lumen we wanted a ‘pre-workout’ test and choosing from a list of activities and durations, she measured our metabolism and told us we were burning mostly fat. Then he told us that we need to fuel our workouts to give us the energy we need (because burning fat doesn’t give the muscles the energy they need to run). However, after that it got very specific, it is recommended that we eat high glycemic carbohydrates such as fruit, dates, bread, or cornflakes between 15 and 60 minutes before the run.

On the way back we measured again and were told we were now burning carbs. No wonder we just ate some bread, but proof that Lumen is right and can’t be fooled. He then told us that we should eat a small portion of low-medium glycemic carbohydrates over the next 30 minutes to two hours: yogurt, milk, muesli, or whole bran. His diet plan is similarly filled with very specific advice, such as eating 45 grams of protein.

Lumen is a very serious, professional tool, although it may be surprising at first. So the company offers one-to-one onboarding video calls and sends helpful follow-up emails that use helpful and supportive language. You just need to fully commit to it – and that will be a problem for many potential customers.

Lumen metabolism tracker: A companion app

Lumen metabolism tracker: A companion app

  • The Lumen app is free.
  • Easy to use and good quality
  • The first two weeks can be frustrating due to the lack of information.
  • Companion App Score: 4/5

The free Lumen app is excellent, never crashing once during our lengthy review. It’s also incredible at holding the user’s hand. It has to be, because who among us knows how and why to use a breathalyzer?

The first thing it teaches you is how to inhale and exhale into the instrument. It then gives a visual countdown for each stage. Now exhale until the circle on the screen turns green, hold your breath for 1, 2, 3 … now exhale until the circle disappears. If your times are wrong, you have to start the whole process over. It’s easy to learn, but it takes a few tries.

After you exhale on your device, the app gives you a view of a semi-circular pie chart divided into five colors. Blue on one end for mostly fat burning and orange on the other end for mostly carbohydrate burning.

For the first two weeks, that’s about it, and it’s a frustrating period because you feel like you’ve wasted your time looking for some useless data. It’s not until you’ve been using Lumen for a few weeks (if you’ve even gotten that far) that it starts to pinpoint what you should be eating when you should be eating, and when. Should you exercise and how much sleep should you get?

Lumen also now offers an app for the Apple Watch that takes data from the breathalyzer, lets you log your carb intake, and if it thinks you need low-carb days (which He looks obsessed) so lets you set your daily ‘carb budget’.
