Garmin-Lumen Partnership Launches Second Phase Integration With Metabolic Fitness Data

Garmin-Lumen Second Phase Integration

Lumen, the maker of metabolism measurement device through the breath, and Garmin International, have launched the second phase of integrating health and activity data.

The second phase will integrate that metabolism data with biometric data collected with the Garmin wearable itself. In that regard, people will now be able to view their body battery and heart rate data (both resting and active) directly in the Lumen app to gain a better sense of how their workout affects their metabolism. The information can be used to optimize their training and their diet based on the results.

According to the research team at Lumen, the trend is clear: Garmin users are now optimizing their fitness routine by training their metabolism, reports BusinessWire.

“Proper nutrition is just as essential as your workout routine, whether you’re just getting started on your fitness journey or training for a triathlon,” said Travis Johnson, global product lead for Garmin Health. “The combination of real-time metabolic data from Lumen and biometric data from Garmin is a powerful tool that lets you make informed decisions about how to fuel your body and achieve your fitness goals faster.”

Throughout the last 3 months of this integration, Garmin users took over 11,000 post-workout metabolism measurements. The results of these measurements were highly successful, as 70% of users shifted to burning fat as a fuel source following their workout. This efficient shift from carbs to fat burn is a key factor to training a flexible metabolism.

Compared to the average user, they also worked out 15% longer, fasted and woke up in fat burn 10% more, and took 18% more daily steps.

“We see that Garmin users who measure their metabolism with Lumen become smarter athletes because they get metabolic feedback in real time on their wrist after workouts. In phase 2, users can connect their metabolism to Garmin’s Body Battery™ energy monitoring feature to optimize their workout readiness with the right nutrition,” says Barak Alon, head of data at Lumen.

The feature integration was first launched in November 2020, as the Lumen metabolism measurement app was made available for Garmin users on the Connect IQ™ Store along with a Health API integration.

In this second integration phase, Garmin users can now directly correlate their Body Battery, heart rate, and workout to see how well their body shifts from carbs to fats as a fuel source.

The new data metrics now available to Garmin users in their Lumen app include:

  • Body Battery
  • Resting heart rate
  • High heart rate

With 1 in 5 American adults owning a wearable device, the future of health tracking is shifting to the combined value of nutrition and fitness data. Innovative integrations such as Garmin and Lumen are at the forefront of utilizing data and technology to determine what workouts truly work for our body through real-time metabolic insights and personalization.


In collaboration with San Francisco State University, Lumen has validated an ongoing study launched in 2020, which shows the validity of Lumen to detect changes in metabolic fuel utilization in a comparable manner with a laboratory standard metabolic cart, providing the ability for real-time metabolic information for users under any circumstances.
